Forward: As written in the forward in my other LED Lights article, I would like “Aquarium Article Digest” readers to know, while it’s obvious I have a bias towards a few particular LEDs and do not care as much for some others; this is based on use, science [much of it simple too such as energy lost as heat], reading/research which IS cited here, and much input from true aquarium professionals, who maintain and set up aquarium systems for a living.
My favortism/opinions are based on the above including one source with over 40 years of hands on experience in the hobby!!
It’s not that LEDs I rate with less favor do not work, they in fact DO work, some quite well.
Though, they ALWAYS use more input energy/wattage to achieve the same results as those I recommend based on actual use, patented emitter bins, and currently known scientific technology & research! Some of the science is basic common sense.
As well, this post/article is meant as a complement to this article:
LED Aquarium Lights, Lighting
This post is also meant as a compliment to a newer article, which admittedly had input with a comparison chart from an employee of an online seller I have much respect for his knowledge:
What to Consider When Choosing Your Aquarium LED Lights
Put simply, this post is meant to dispel the many myths as I see them… circulating about what many LED lights can and cannot do for your aquarium, so as to help others make an educated decision about their aquarium lighting.
I would be grateful if readers here would read all the cited references as well as my other articles explaining LEDs for further information as to why not all emitters and drivers are the same and why a 30 watt LED fixture using the latest emitters/drivers can surpass a 60 Watt LED fixture.
Without reading the above articles first, as well as many of the cited references & resources, along with THIS article, one CANNOT make a totally informed decision about LED aquarium lighting based on this LED Review article.
Whenever choosing an LED, make sure it’s known as to what is trying to be achieved, such as Reef, Freshwater Planted, Nano Reef, Deep Freshwater Planted, etc.
Then know how to compare “apples to apples”.
Avoid placing too much emphasis on these attributes:
This is where the less easy to discern PUR/PAS (Useful Energy/Photosynthetic Action Spectrum) is MUCH more important.
See Reference: Aquarium Lighting- Measuring PAR
More information about PAR and Quantum Sensor, please see Apogee Instrument Knowledge Base:
Aquarium PAR Meter Information
EVEN When comparing different LEDs as there’s a wide difference in output per watt per emitter and many poor quality lights make up for this in a shotgun approach of dozens of low output emitters and higher wattage, which IMO defeats one of the purposes of LED lighting: “lower wattage”.
See also my other article: Aquarium LED Lights, Lighting
In fact, most of these fixtures listed here [with a few exceptions such as the Marineland Double Bright and a few not listed such as the Sky LED], will keep reef life or freshwater planted aquariums.
I ask for readers to have an understanding of my complaint, which is these LEDs are marketed as the best when in fact a simple look at the facts of Kelvin, PUR/PAS [much more so than PAR], and circuitry/emitter technology shows many as “wanna bes”, which often require 3-4 times the electrical wattage and have much shorter life spans than the truly best LEDs.
Here’s how each of these reviews will be laid out.
*Zetlight Qmaven/Maxspect R420R/TMC V2 iLumenAir
They are all made in Honk Kong, however Zetlight reserves some of its technology ONLY for their name brand line such as the smart fan and better Cree emitters over Bridgelux.
Zetlight also has other LED models, not reviewed in this article at this time. (Mini Aquarium Series, Nano Aquarium Series, Aqua Aquarium Series, Pro Aquarium Series, Project Aquarium Series, IOZEAN Aquarium Series, Lancia Aquarium Series, and Shieldo Aquarium Series).

12 x 3W Royal Blue (465nm)
V2 iLumen Air 900- 170 Watt
2 x 35W (6500K) diodes
24 x 3W Royal Blue (465nm)
3 x 3W Red (640nm)
3 x 3W Green (530nm)

Designed to be primarily cooled passively, the body is entirely in aluminum, serving as a large heat sink. With the aerodynamic design, cool air is brought through the bottom of the fixture and heat will be dissipated through the aluminum chassis. With a built-in temperature controlled system, with active cooling.
In the end, my choice would be the ZetLight, since is uses the best emitter combination of the three, with the least wasted PUR/PAS energy.
The Maxspect would be my last choice with the strange mix of warm white and cool white emitters to balance out the otherwise excellent blue/violet emitters thus resulting in a considerable amount of wasted light energy outside of optimum PUR.
The use of cooling fans implies that the Zetlight Qmaven, Maxspect R420R, & TMC V2 iLumenAir all use 0-10V “Current Reduction” versus the superior PWM to control the emitters.
See: Aquarium LED Lighting- PWM
The “smart fan” used by these Zetlight manufactured fixture is another nice feature, since it does not require constant operation of the fan.
The negatives again are the LACK of energy conserving, light efficient PWM controller technology, less than desirable PUR due to the many colored LEDs, and less than optimum PUR efficient emitters.
Part of the problem is the use of warm white and cool white emitters, such as the Cree XPG 3000k warm white, which is not an emitter best used for aquatic applications.
This said, these are nice LED fixtures for those desiring a good light for coloration of their reef specimens where an efficient lower wattage per PUR/PAS fixture is not important. These are clearly not the best as per the known science of aquarium lighting, but are certainly reef capable at albeit a higher cost of operation (and higher carbon footprint), as well as shorter useful product lifespan.
The bottom line is, while not the very best as per the more important PUR (NOT PAR), emitter kelvin ratings, and emitter technology, these are a less than efficient BUT VERY reef capable LEDs with MANY unique features, which many would find very useful in their reef lighting applications.

The Mazarra-X Lighting system can be connected to PC through USB, allowing users to update firmware easily through the USB connection. Upcoming Maxspect Computer Control program will also allow users to program photo-period profile directly from the PC and upload the profile onto the master module.
The use of cooling fans implies that the Maxspect Mazarra use 0-10V “Current Reduction” versus the superior PWM to control the emitters.
See: Aquarium LED Lighting- PWM
The Maxspect Mazarra lighting system is one the first LED systems on the market to utilize the 410/420nm Super Actinic LED chips (violet). Maxspect claims this spectrum is crucial for the success of any reef and water plant aquariums as it is required by Chlorophyll A for photosynthesis, where absorption peaks at 412nm.
While this claim is not fully substantiated, there is evidence that SOME corals need this spectrum for proper growth. However, little evidence exists that this spectrum is needed for freshwater aquarium plant growth.
Other fixtures do have this color of emitter as well.
Maxspect Mazarra Warranty = 1 Year
*TMC AquaRay AquaBeam/AquaGro- 2000 Reef White, 1500 Ocean Blue, 1500 GroBeam/Colour Plus Tiles
TMC AquaRay is one of the leaders in both Reef and Planted freshwater aquarium LED lighting [especially in Europe], with 11 different module fixtures to mix and match depending on species being kept and aquarium specification. Emitters are fully lincesed or patient, meaning no other fixtures have these emitters. They also have an exceptional 5 year warranty to back them up, which is far longer than most all other aquarium LEDs.
Based on the known science of aquarium lighting, what sets their LED Light fixtures apart are these factors:
Instead of warm white or cool white emitters, the AquaBeam/AquaGro LEDs use more reef or planted freshwater friendly kelvin temperature emitters. These emitters are also aquarium specific meaning they are meant to be used in a more wet environment and can handle larger voltage swings, due to long term exposure to moisture.
Other good/excellent “High End” LEDs such as Aqua Illuminations, EcoTech, and Kessil do not daisy chain their emitters either.

30 watt AquaGro Colour (Color) Plus
4 x Cree XP-G 6500K daylight white
2 x Cree XP-E green

This color mix is comparable to many other LEDs, which compliment the higher PUR emitters with colors to make corals and fish colors pop. The Colour Plus has a beam angle of 120 degrees, a lux of 3750, and produces a PAR rating of 129 at 400mm (15″).
While this is certainly a capable LED light, TMC does NOT market it as a sole reef light, nor should it be used this way. Unless a FOWLR, low to medium light planted, or fish aquarium, this is best used as a compliment to all other TMC AquaBeam and GroBeam lights.

This is what really sets the TMC AquaRay apart from others, since there’s little heat loss with PWM compared to other methods. This is also for long-term security of the emitters, as over time with a moist environment, spectrums and emitters can start to degrade.
The AquaRays do not have fans, which is a large plus considering the life of the fan will never last as long as the emitters are rated for. With less heat, these means more energy is being used as light and less watts of energy are being used. This also helps makes the fixture completely IP67 waterproof.
Probably the only downside to this technology is the complexity of the circuitry and it does come with a price. A separate controller is needed. TMC chooses to keep their dimmer separate, as not everyone needs it and the fixtures can simply be raised and lowered or a good grounded timer can also be used [which is what most persons used until LEDs became practical].
A higher pitch sound also has been reported with PWM dimming, but is something not noticeable unless someone is specifically listening for it and can hear it over other sounds of the aquarium. It is also worthy of note that other Aquarium LEDs use fans, which make their own noise and often breakdown prematurely, so this is a draw here.
My only other complaints are that the TMC controllers are not as user friendly, although their new Multi-Controller 8 with new features certainly void this issue. Now the new controller has more user features not even found with other common fixtures. Either way the use of PWM and lower heat loss resulting in more light overrides these issues in my experience/opinion.
See Reference: Aquarium LED Lighting- PWM
The result of these industry leading technologies as well as not going with the gimmicky, yet popular multiple color emitters such as green/yellow/orange emitters, these TMC AquaBeam & AquaGro GroBeam have the highest PUR output for the lowest wattage input, often by a very wide margin.
Further Specific TMC AquaBeam/GroBeam Information
TMC has changed its 1500 XG Ultima line of LED Fixtures to the NP 1500 Ultima.
As well the 500/600 is now an “Ultima 600” and the GroBeam 1000 for planted aquariums has been upgraded to the GroBeam 1500 Ultima.
As of August 2013, the new Reef White 2000 NP Ultima was released
See these product resource links:
Pictured below is a Reef White 2000 NP Ultima and 600 Ultima NUV LEDs over a 60 Gallon Reef Aquarium
The new 1500 & 2000 LED combines the exclusive and licensed Cree 10000K XT-E daylight emitters with the high output XT-E Fiji Blue.
Even more impressive is the TMC Ocean Blue NP 1500 & Reef White NP 2000 includes the patented innovative NP Blue Osram Olson emitter which is specifically designed for photosynthetic reef life, providing a blue light, which still is full spectrum.
It provides the growing power of 20K, while having a 16K appearance. This is a higher level tech emitter, not available in any other aquarium fixture.
As well these TMC fixtures, continue to use advanced driver technology, which does not waste nearly as much heat energy as other comparable LED fixtures. Instead, much more energy goes to actually lighting your aquarium.
The TMC Ocean Blue NP 1500 is an excellent choice for aquarium keepers with tanks under 22 inches of depth desiring a very high output blue and daylight light combinations from a small footprint yet high output (high PUR) aquarium LED.
This is a COMPLETE LED for reef aquariums with a PAR reading at 15 inches of 142 µEinsteins/sec/m2 PAR and 4250 lux at 400 mm with no supplementation needed assuming complete coverage.
Here are some important points as to what the NP 1500 series LED lights can and cannot do:
The NP 1500 with a beam angle of 120 degrees has a 24 x 24 inch light spread, with fixture at optimum 8-12 inches above tank. While the light spread is about 18 x 18 for the 2000 Ultimas, which have a 60 degree beam angle.,/li>
It is also noteworthy, the combined emitters used in the NP 1500 have a higher PUR in proportion to the testable PAR (PUR is the actual useful light energy).
Below is a video with a reef aquarium using AquaRay Ocean Blue NP 1500 LEDs
Reef Aquarium with Ultima NP LEDs Video
This is an important note, although not as easily verifiable with easily and inexpensively obtained equipment (such as a Light Spectrometer). There is simple, albeit not fully accurate equipment such as lenses that can display certain wave lengths to help with this determination.
Please also reference this EXCELLENT article:
PUR vs PAR in Aquarium Lighting
A 75 gallon planted with two GroBeam earlier generation LED tiles is pictured to the left (picture courtesy AAP)
The 2000 tiles are still the most focused best depth penetrating (albeit with the lowest light spread) of all TMC AquaRay lights and quite bluntly MOST any other aquarium LED but for the Orphek & Kessil!
This makes the AquaBeam 2000 LEDs the best choice (as per TMC products) for tanks over 20-24″ in depth including deeper hexagon or similar reef aquariums.
As noted earlier with the 1500 NP Ocean Blue, this LED uses the exact same emitters, but with lenses producing a much smaller 60 degree cone of light with much more depth penetration.
Below is an SPS Frag grow out tank under TMC AquaRay 1000 LEDs:
The TMC 600 models are excellent as stand alone LED fixtures or as compliments to the 2000 and even 1500 models so as to add light spread in larger deep tanks.
See this review of the 600 Ultima:
*New TMC AquaBeam 600 Ultima Aquarium LED Light
TMC also now utilizes the newest licensed XT-E Deep Blue 450nm un-lensed emitters in their AquaBeam Fiji Blue Fixture (pictured above), which is an excellent compliment to the Marine White or even the AquaBeam Reef Blue for a very nice full blue spectrum, specifically for enhancing the fluorecence of corals. Notwithstanding, the EcoTech Radion does a nice job here too mixing blues.
See this product resource link:
AquaBeam Fiji Blue LED
The Picture to the Left displays the new TMC Mini 500 LED which is designed for small Nano Reef Tanks under 15 gallons (the picture displays this light with a “MountaRay” bracket for easy attachment to small tanks)
See this product resource link: TMC AquaRay Mini 500 & 400 LED
While I personally have found this an excellent new offering from TMC, I find the moonlight mode somewhat a gimmick based on known facts about moon light and its affect on corals, etc. However, my understanding is TMC is simply bowing to customer demands here.
Please Reference: Aquarium Moon Lights Review
This is a far better choice for a small nano planted or a reef refugium than any CFL, as at 12 watts, this LED fixture will out produce ANY CFL under 80 watts!
The picture above is of a 29 gallon aquarium with two Mini 400 Tiles providing excellent plant growth (click to enlarge).
Also see this review of the 400 from Aquarist Magazine:
TMC Aquaray Mini LED 400 Aquarium Light Tile Review
Also see LED Aquarium Lights & Lighting for further LED information and as well for further information about the TMC AquaBeam 600 and 1000 Ultras.
TMC had a failure of their quality control for the Ocean White 1500 in that CRee sent cool white emitters (those used by EcoExotic at the time) instead of the patented 9000-10000k XP-G emitters. These were installed in a few runs in the spring of 2012.
The fixtures in question have these numbers on the box side:
It is noteworthy, this mistake was caught by a couple of customers with a good knowledge of what a quality LED should produce in light energy and they noticed the difference from other TMC LEDs since these Cree cool white emitters produce a more yellow, lower quality PUR light.
Here is an excellent newer website documenting the LED research at Saint Mary’s College of Maryland by Dr. Walter Hatch, THIS IS A MUST READ!
TMC AquaRay LED Warrenty = 5 years
*TMC AquaBar LED:
This is a new offering by TMC that is made to TMC specification in China with 6500k White Samsung LED emitters instead of the patented Cree & Osram Olson Emitters supplied with their premium AquaBeam and GroBeam line of LED Lights.
Update: The AquaBar has been taken off the aquarium LED market.
*Current Satellite Freshwater LED:
The Current Satellite Freshwater LED is a relatively new LED sold primarily at discounters such as Amazon or Petco and is quite frankly typical of LED lights sold at discounters in that it is full of gimmicks that will appeal to those with little knowledge of aquarium lighting, but are easily marketed to by “bells & whistles”.
The fact these lights get good reviews on Amazon is why consumer reviews such as these are not to be relied upon.
I will use the model #4007 as an example for this review.
This LED is designed for 36”-48” aquariums and uses 25 watts of electricity.
The LED emitters consist of 72 White & 36 RGB (Red, Green, & Blue) emitters.
First the good, this truly is a feature rich freshwater aquarium LED, with a nicely laid out controller.
Once we dig into the science of lighting, we see that this light achieves its 6500 Kelvin with no-name emitters. Not even known quantity off the shelf Bridgelux or similar, which at least reasonable quality LED fixtures utilize.
To balance out the 25 watts between 108 emitters takes at least a reasonable driver circuitry, which this LED does not do since the emitters are clearly daisy chained together as one would do with Christmas lights.
The result is uneven voltage which affects the quality of the light spectrum as well as the life of the emitters, hence the poor one year warranty.
Also, is the fact that the green emitters are useless light energy as per photosynthetic life, and even research into Redox shows that fish too benefit from good quality light. The un-balanaced blue emitters can also lead to increased algae growth, in particular black beard algae. This is a common problem with many of these low end LED lights marketed for freshwater aquarium keepers by discounters such as PetCo and Amazon.
Now let’s look at typical cost when compared to a couple other freshwater capable LEDs.
At about $105 for the model #4007 you get an LED, which uses 25 watts and can light an aquarium comparable to a 40 watt T8 aquarium light.
This would be reasonable lighting for fish, but far from the best too. More importantly this would NOT be the best light for high light requiring plant growth or to fend off algae.
My point is this is a well marketed LED, which should be avoided if quality and long life of the fixture are at all important to you.
Just based on warranty alone, the end price will actually be higher than a better PUR light quality LED, so your value goes right out the window!!
Current USA Satellite Freshwater LED Warranty = 1 year
*TMC Aqua Red/Blue Flexi-LED & Truelumen (by Current):
While TMC is an awesome company, these products are primarily decorative and are mostly useless for lighting an aquarium as per the necessary light energy, especially needed by freshwater plants or symbiotic zooanthellic algae found in many corals, clams, & nudibranchs.
That said, TMC is not marketing this product for anything other than minor supplemental or decorative lighting.
Please click on the picture to enlarge
The picture to the above/left shows the TMC Flexi-Red LED Light mounted on an aquarium both at night with only the Red LED “on” and in Daylight with a TMC GroBeam also illuminated (‘On’).
As you can see in operation with the GroBeam this Flexi-Red only provides subtle highlights of red (which might be great for some freshwater tetras, discus, etc.), however at night by itself this Flexi Red LED does add an interesting effect in the aquarium.
The Flexi-Red Strips are excellent for use with nocturnal fish such as Blennies, as many nocturnal fish are active with low level red lighting present in their aquarium. As well as a supplemental light, the Flexi-Red can be added to planted aquariums to add a small amount of additional near-infrared red light energy for plants such as Rotala.
The blue strips are excellent for use as a moon light for those who prefer a blue color for night lighting, notwithstanding that moon light is not actually blue, but this is the color most persons seem to prefer regardless.
Reference: Aquarium Moon Lights Review- Is Moonlite truly Blue
TMC Flex Red/Blue Adhesive LED Aquarium Lighting
The TrueLumen by Current USA is similar, however it is unfortunately marketed by many as a main light source, while as with the TMC Flexi-Red the TrueLumen is only for supplementation.
The Kelvin Color temperatures (other than the Rose, Rose/White) are primarily for marine aquarium supplementation.
Both these products are nice ideas when properly used with the TMC available in 18 inch strips and the TrueLumen available in 10 inch strips.
Both are very easy to install with the TrueLumen available in more varieties while the TMC is a better value (due to a considerably longer strips for only a marginal amount of $ more)
TMC Aqua Red/Blue Flexi LED Warranty = 2 years
The popular “Ecoxotic Stunner” is simply for additional lighting, not Reef or planted freshwater aquarium lighting. The LEDs are not of the output, wattage, or even the same generation technology as the LEDs used by other tech.
As well the PAR output generally is below the necessary 50 mmol required for photosynthesis. Now a days, with new higher PUR tech, something like 20 mmol of PAR is all that is required for photosynthesis. This is with more useful energy in the PAR spectrum (PUR), not just any mmol throughout the whole PAR.
Ecoxotic Panorama Strips have 12 older technology 1 watt emitters (vs. the 2.4 watt high PUR emitters used in other fixtures). More emitters are required due the lack of precision (useful energy output, etc).
That said, while the Ecoxotic Panorama Strips are not top level technology, these are still a big improvement on the “Stunner” and can be considered for Reef Tanks. A popular model is the Panorama Module 8000K/453nm Actinic Blue, which consists of 8 white lights and 4 blue lights.
The newer Ecoxotic Panorama Retro 36 is closer to the higher end LEDs, even then the emitters are still not of the high output useful light energy bins.
Please reference: Aquarium Lighting, Useful Light Energy
Worse is Ecoxotic’s approach to patents for the emitters they are using is “go ahead and sue me”, not the kind of company I think any honest person should support.
There is a reason that the better LEDs are priced as they are. It is called licensing.
(See Orbital Technologies Corporation Statement; Patent Infringement)
Ecoxotic Warranty = 1 Year
*Marineland Reef Capable, Single & Double Bright:
The over hyped Marineland Double Bright LED lights from Marineland are also purely for highlighting fish only or complimenting other lights.
As with the Ecoxotic Stunner, these are much older “cheap” technology LED emitters of 1 watt each that do not come close in lumen, focused lumen and PAR output as the newer technology LEDs.
The so-called “Reef Capable” LED’s by Marineland, albeit much better than the Double or Single Bright, are still 2 generations behind the emitters used by the other newer generation lights, which utilize the best emitters, the best drivers, and PWM technology.
These Marineland LED’s have a PAR reading, with the newer Apogee PAR meter, above 80 umol at a distance of 18 inches, but this is not the full story.
Since it’s useful light energy (PUR), which is MOST important and this Marine “Reef Capable” LED with its 21 inferior one watt emitters is severely lacking here.
While the “Reef Capable” are what they say they are in being capable of keeping some photosynthetic reef life, their 21 one watt emitters (on the 18-24″ model) are not of the best PUR available in the better newest generation emitters and yet the Marineland “Reef Capable” are about the same price as the vastly superior LEDs. In fact, using 30 watts of input energy of high output emitters will well out produce the largest Marineland Reef Capable with its 54 one watt low PUR emitters.
See the picture/graph below, which clearly shows the extreme short comings of the Marineland emitters. While there’s a correct spike in the blue (which most older technology emitters have been able to achieve), there are not the two essential spike in the infrared (red) wavelengths.
In fact, the vast majority of light output is in the useless green/yellow visible spectrums which will provide a PAR reading that is false as per actual useful energy (PUR). As well, give the human eye a false sense of a larger volume of light energy when in actuality this is clearly not the case.
Please reference: Aquarium Lighting; PUR.
*As another update to the Marineland Double and Single Bright LEDs, I met with one of my aquarium maintenance colleagues and discussed the results further and re-examined this LED light in action.
After further examining of the low PAR output Chinese emitters used by Marineland as well getting further expert input that these lights are at best for fish only tanks. Basically, the Marine Single Bright had no more output than an 18″ 15 watt T8 Fluorescent aquarium light and should be sold/purchased as such!
In summary, the Marineland LEDs, whether the Single or Double Bright highlight LEDs or the better “Reef Capable” LEDs are still vastly inferior LEDs sold primarily at only often questionable mass merchandisers such as Pet Mountain.
Marineland Warranty = 1 Year ?
*Blue Moon Aquatic 90-watt LED:
As you can see with the picture/diagram below, this LED light is much to heavily weighted in the blue spectrum of light for an accurate PUR (Useful Light Energy).
I would only recommend these LED fixtures as a compliment to 6500K to 10,000K light and even then if you get a great deal, otherwise for 1/3 the wattage you have a much better LED light in better technology.
Reference: Aquarium Lighting- PUR (Useful Light Energy)
The other problem with these two LED Fixtures is the more emitters, the more complex and expensive the drivers, so when you have a fixture such as this TaoTronics or Blue Moon LED with a shotgun approach of emitters yet with essentially no drivers you are essentially stringing hardware store quality LEDs together over your aquarium.
Blue Moon Warranty = 2 Years
*Evergrow & Ocean Revive LED Aquarium Light- Including the OR-D120:
Both the Evergrow and Ocean Revive are the same LED fixture from China using the same lower end Bridgelux emitters.
The Ocean Revive OR-D120 uses 120 watts to achieve the questionably similar PUR output to a high out 30 watts unit, which defeats the purpose of LED energy savings.
As well this is another LED, which utilizes heat producing, energy wasting 0-10V current reduction technology rather than PWM technology, which is much more energy efficient.
Reference: Aquarium LED Lighting; PWM
The Ocean Revive uses these common Bridgelux binned emitters:
(2) Red 660nm
(2) Green 520nm
(20) Blue 460nm
(7) Royal Blue 450nm
(4) Violet 420nm
(8) Cool White 12000K
(6) Neutral White 7500K
(6) Warm White 3500K
While one could argue the green emitters add nice colors, the science cannot be argued with, that is these are purely useless lights when it comes to ESSENTIAL PUR.
As well the use of warm while emitters is also very questionable, as no one would ever place Neutral or especially a warm white fluorescent light over their reef aquarium, YET it is somehow OK for an LED?
The cool white is also a questionable emitter.
Here are a couple of Spectrograms, which further prove this point, as you can see most of the light energy is NOT within the important spikes required by photosynthetic life, rather mostly in the middle useless nanometer spectrums.
In the end, when science is applied, not opinions or sales hype, one has to discount the “useful energy” output of many of the emitters, which in part (besides the use of “current reduction”) is why this LED requires 120 watts of energy to even compete with a much better 30 watt LED fixture using patented emitters and much better driver & PWM technology.
The above said, this IS a reef capable LED light, just at a cost of much more electricity used (& higher carbon footprint), with a much lower PUR as per energy used than the MANY much better LEDs, as well as a much shorter fixture lifespan due to heat damage. But the color mix is nice and pleasing to some, especially those who place appearance over technology.
Some people will claim the addition of these color emitters are for coloration of the corals and prefer color over optimum growth of the specimen.

*Aqua Illumination SOL:
The Aqua Illumination SOL Aquarium LEDs use good quality, albeit older generation Cree XP-G 6500K and blue/royal blue XP-E series LEDs (AI does NOT have the license “rights” to the latest CRee emitters). The lenses and over all design is top notch.
The driver/circuitry is well designed as there is less heat generating heat spikes than some other LEDs using Current Reduction.
Reference: Current Reduction Versus Pulse Width Modulation
|Here is a break down of the popular AI Sol Super Blue:
Cree: XPG, 6500K
These LED fixtures are marketed more on features in my opinion rather than what is important: Useful Light Energy (PUR), NOT PAR only as some reviews may claim.
Please reference: Aquarium Lighting- Useful Light Energy, PUR.
This said, the AI Sol LEDs have interesting and admittedly cool features include proprietary 40 and 70 degree lenses and feature rich controllers that do an excellent job of getting light where it is needed.
The Aqua Illuminations LEDs are capable LED lights for many light reef applications with many reporting reasonable results.
I recently was reading forum posts and noted a lady had read a lot of information and despite the plethora of good information, went with the bells and whistles of the AI Sol Blue over the facts of newer technology LED emitters in better kelvin temperatures for reef aquariums??
However from my understanding of the science of reef lighting, this LED does not have the best balance of blue and higher kelvin daylight, nor is the PUR of the emitters of the capability of the newest CRee emitters not available to AI.
This LED is essentially an older version 6500K planted freshwater light with good saltwater depth penetration of maybe 12″, combined with an excellent but older binned (non patented) version XP-E blue CRee emitters, which are good for aquarium applications under 20 inches but not for deeper tanks as many unaware reef keeper have used these LED fixtures for.
It appeared to me, the bells and whistles won out, but hopefully since she mostly has fish (from what I read), this will not present too many issues with the few softies corals she does have (soft corals should do well with an AI Sol LED).
My point is that that while the Aqua Illumination SOL is a good and capable LED light for many reef aquariums, at the price charged for this LED light fixture, there is little reason to pay more, use more electricity, and get less in my opinion.
In my opinion, do not let bells and whistles win out over facts in your important aquarium lighting decision.
This said, I will note that based on others results and known facts about the emitters used in the AI Sol, this is still a good choice for reef tanks under 20 inches of depth (based on emitters used, the EcoTech Radion, and TMC AquaBeam Reef White, and Kessil LED are better choices for reef tanks over 20 inches).
*Aqua Illumination Vega:
This is a really clever & unique concept as per the controller.
Here is a quote from Aqua Illumination’s website:
“With built-in wireless control capabilities you can connect wirelessly to the New Controller or upcoming Director platform with ease and freedom”
This in my opinion is one of the most innovative controllers that is chock full of features, including the future “Director”!
HOWEVER, I must also point out the obvious negatives and that is this an aquarium LED light fixture, which is feature rich with lots of bells & whistles, it still lacks where it counts in my opinion/research; IN USEFUL LIGHT ENERGY!
Here is a list of Emitters in the AI Vega, it should be noted that all are from generic emitter bins:
4 – Cree XM-L Cool White
4 – Cree XP-E Royal Blue
4 – Cree XP-E Blue
4 – OSRAM OSLON Deep Blue
2 – Cree XP-E Green
2 – OSRAM OSLON Deep Red
4 – Cree XM-L Cool White
Here is the Vega Color Spectrograph:
Please note that while this is one of the better spectrographs demonstrating PUR compared to many aquarium LED fixtures offerings, which is why this is one of the better LED fixtures, one has to question the use of the generic cool white emitters, which can be shown to basically be wasted light energy in the middle spectrum as well as the green emitters.
This equals as much as 30% of wattage input goes as light energy OUTSIDE of optimum PUR!!!

*Aqua Illumination Hydra FiftyTwo:
Here is a break down of the AI Hydra FiftyTwo:
16 – Cree XP-G2 Cool White (> 70 CRI)
4 – OSRAM OSLON Deep Red
4 – Cree XP-E2 Green
12 – Cree XT-E Royal Blue
8 – OSRAM OSLON Deep Blue
4 – SemiLED 415nm Violet
4 – SemiLED 400nm UV
This is one of Aqua Illuminations newer offerings.
A nicely made and excellent “high end” LED fixture that steps up from previous offerings with this 135 Watt LED Fixture.
This fixture along with the similar TwentySix has a very eye pleasing color balance which along their sleek design and balanced 80 degree optics with 90% optical efficiency are their main selling points. The wireless controlling features are also nice, although lacking of more efficient heat loss reducing PWM, hence the need for a fan.
Moreover, these LED fixtures still use “binned” Cree XP-G2 Cool White LED emitters which is inferior aquarium lighting PUR/PAS based on my fact-finding, as it has lower kelvin color temperature rating than is considered best for marine reef lighting. Additionally, this LED uses green emitters, which while these are nice for color, these also considerably lower the important PUR/PAS output (but are great for adding colors to your aquarium if this is what your desire).
This is my guess as to why AI publishes the peak PAR of 304 µMol [for the FiftyTwo], but ignores the PUR as a light can be excellent with PAR but still lacking in the more important PUR.
I would also question the use of 400 nm emitters as while these may look nice, I do know from others use of UVA lights, that some burning of corals has occurred (although I have no evidence that this will occur with these LED lights). There is little evidence these 400nm emitters provide much if any useful PAS to corals.
A positive though is the Osram Oslon Deep Red emitters do a nice job balancing the many blue emitters.
The Aqua Illuminations TwentySix is another well made/designed LED fixture similar to the FiftySix except with half of the same emitters.
Here is a break down of the AI Hydra TwentySix:
8 – Cree XP-G2 Cool White (> 70 CRI)
2 – OSRAM OSLON Deep Red
2 – Cree XP-E2 Green
6 – Cree XT-E Royal Blue
4 – OSRAM OSLON Deep Blue
2 – SemiLED 415nm Violet
2 – SemiLED 400nm UV
In summary, while a nicely packaged and widely popular aquarium LED, the “Hydra FiftyTwo” and “TwentySix” still pursues PAR numbers and colors over PUR/PAS and utilizes the less efficient “Current Reduction” albeit with wireless features driver controlling technology, which AI utilizes for their other LEDs.
Aqua Illuminations Warranty = 1 Year (with certain sellers in the UK providing a 2 year warranty at their expense)
I watched a video promoting this, which missed a key point in my experience/opinion, where he only used a PAR meter which does not show PUR, which is MOST important and requires a spectrograph to show more correctly.
Please Reference: Aquarium Lighting; Measuring PAR
This video review did show the Radion can and DOES maintain corals, but it is using the “shotgun approach” in my opinion versus a direct approach of specific LED emitters and use of PWM technology, which in the end require about twice the wattage input for the same PUR results of an AquaRay Ultima.
By “shotgun approach” I mean the common way in the past of lighting aquariums with multiple lamps using T8 or T12 bulbs to obtain the necessary light energy for photosynthetic life rather than specific light nanometers [this is not to say the EcoTech are even close to a T8 or T12 lamp, as they are vastly superior, this is only used as an analogy].
An example of what I mean, are the cool white and green emitters used, see below.
The EcoTech Radion, emits a significant percentage of its light in the blue as well as some green, yellow, & red spectrums
Here are the emitters used as of 2013 for the Radion XR30w PRO:
• 8 x White: Cree XT-E Cool White (5W each)
• 4 x Red: Osram Oslon SSL Hyper Red (3W each)
• 4 x Green: Cree XP-E Green (3W each)
• 8 x Blue: Cree XP-E 468nm Blue (3W each)
• 8 x Royal Blue: Cree XT-E 442nm Royal Blue (5W each)
• 4 Indigo: SemiLEDs UV, 415nm (2.5w each)
• 4 x Ultraviolet: SemiLEDs UV, 405nm (2.5w each)
Max Wattage of Radion Fixture: 155 Watts (170 used)
This is certainly a nice mix of Blue emitters with both the XP and XT, albeit generic emitter bins from Cree. The Indigo and Ultraviolet emitters certainly add nicely to the blue mix.
The mix of Blues is probably the best aspect of the EcoTech Radion, and why when compared to the AI Sol, I would pick the the EcoTech for any tank over 20 inches in depth when compared to the Aqua Illuminations.
The overall spectrum is probably one of the best, comparable to the TMC AquaRay Reef White NP 2000 Ultima
See this article for a Spectrograph comparing the Cree Blue emitters (although the ones used in this article are not generic off the shelf Cree emitters):
PUR vs PAR in Aquarium Lighting; Including Spectrographs
The use of cool white and green emitters is questionable as per references cited here and elsewhere in this article, as well as other researched articles.
I also mildly question the use of Red emitters for Reef Lighting applications, since photosynthetic zooanthellic do not require as much near red lighting spikes and also since most corals and their symbiotic photosynthetic zooanthellic have adapted over eons to the more blue environment of the oceans versus photosynthetic “higher” plants found in freshwater applications.
From discussions with other reef keepers, they have not noted any improvement with added red lighting and in fact have anecdotally noted slower coral growth.
The other misleading aspects are the completely useless RGB and capacitive touch ‘features’. Controlling your RGB (Red, Green, Blue) of your light has little bearing on obtaining the exacting nanometer spikes necessary for photosynthetic life.
There is no known benefit from the RGB feature and in fact some reviews state this can be stressful/harmful to coral. The reason is above spectrograph output only holds true when the emitters are run at the operating voltage and current that they were designed for unless PWM is employed. As soon as that simple voltage rheostat is used (“control technology”) or RGB is altered, the spectral output changes.
As noted in other articles cited/referenced here, the emitter choice is just part of the LED equation, the use of “Current Reduction” instead of the vastly superior PWM technology is a major drawback of the EcoTech Radion.
The evidence is the requirement of a cooling fan, which can break down from the heat produced, one reason for the 1 year warranty offered by EcoTech in my opinion.
Further Reference: Radion XR30w Gen 2 Fan Failure.
More importantly, the excess heat which requires a cooling fan also represents a considerable amount of lost input energy to heat that could be going to lighting your aquarium reef specimens. This is NOT an opinion either, as it is basic science that energy going to produce heat is energy NOT going to light!
Another evidence is that the Radion Pro produces 1100 µMol•m²•sec PAR from 155 watts of input energy at 6 inches of air, but when compared to the before mentioned AquaRay Reef White 2000 NP Ultima, the AquaRay is rated at 380 µMol•m²•sec at 15 inches of air.
Just assuming both were at 15 inches of air, so as to compare equally otherwise, when you multiply the 5 AquaRay 2000s at 30 input watts to equal the Radion Pro, you get 1900 µMol•m²•sec. So in other words (using these numbers), just in PAR, you only get half the output per wattage of energy used for the EcoTech when compared to the AquaRay LED.
As well since we were comparing EcoTechs number at 6 inches, and AquRay at 15 inches, this also would increase the AquaRay numbers by even more.
The end result is a fixture that may require about 1.5 watts per gallon to light an advanced reef tank compared to .8 watt for, as an example, the AquaRay Ultima.
What I have noted from my own research and that of my aquarium design & maintenance friends is that the EcoTech Radion is well marketed to the point that many if not most forums and aquarium stores assume this is the best LED available when although excellent, it is not necessarily the best as per reasons and research cited here.
Even EcoTech’s own customer service [according to a friend who forwarded me an email] will refer questions about their product to forums.
See this quote:
“I would recommend doing a search in some online reef forums”
So, all I ask is that one does there research, do not just take my word, as while these are certainly an excellent reef capable LED light, these are not necessarily the best. The bells and whistles also certainly may be what one buyer would desire, but another buyer might prefer an equally reef capable LED that is more efficient with less energy lost to heat or used as green light energy (that has no known PUR benefit).
In fact as per electrical saving alone, this fixture will cost you $62 more per year based on running at 12 hours per day and with an average electrical cost of .13 per kWh. Factor in the one year warranty and lower lifespan (1 year warranty) and this can be a very expensive Reef Aquarium LED to purchase and keep over time!!
Finally as per a comment asking me to back up my claims with data, while I cited references throughout this article, the above three, which includes my base article about LEDs, are also now added just above.
As well as the Radions own data as per emitters used, simply reading the references and combining this with the Radions own published emitters pretty much backs up my statements, not to mention hands on use by others I know and the second reference above.
CRI is also often cited as a selling point for the EcoTech, however this is not a parameter a reef keeper needs to be concerned with as this is for human lighting; see Aquarium Lighting- CRI
EcoTech Warranty = 1 Year
TMC had a quality control failure in 2012 where-by these same cool white Cree emitters from EcoTech were used in their Ocean White 1500 XG fixtures instead of the correct patented XPG 9000-10000k emitters.
What is interesting is this mistake was caught by knowledgeable customers, one of whom made a spectrograph so as to back up their claim that these were not the correct emitters.
Why I find this interesting and why I post this in the review of the EcoTech LED is that those with reasonable knowledge of “Useful Light Energy” easily spotted this problem, yet based on friends in the retail industry and others will argue about CRee licensing while missing this very simple and basic problem with the LEDs using Cool White emitters.
*Kessil A360WE Dimmable Special Blend LED -Tuna Blue Wide & Kessil A160WE:
This is a very sleek and compact LED light, one of the better ones in my opinion. The Kessil LEDs also use patented emitters.
Kessil’s emitters are patented Dense Matrix LED™ technology which concentrates multiple LED chips into an array.
The Kessil A360W (the ‘W’ is for wide angle) is their flagship as of the most recent revision of this article.
Multiple Kessil A360Ws can be controlled with a single Apex Controller—two channels are required for each Kessil controlled. Future versions of the Apex Controller software will add functionality to the Kessil A360W. An example of this added functionality is a more gradual dimming and color shift.
The A360W still has the two knobs, just like the A350W. But instead of one knob controlling the blue LEDs and the second knob controlling the white LEDs, one knob is used to control overall intensity and the other knob the blue/white LED spectrum mix. You can tune a preferred color within the spectral range thousands of research and testing hours determined to be the optimal spectral points.
The A360W is a wide angle model has a beam spread of 70 degrees vertically (140 degrees edge-to-edge) and is recommended for larger tanks that are relatively shallow while the Kessil A160WE Coverage Area is up to 24″ surface diameter for fish-only/soft corals and up to 18″ surface diameter for mixed reef with LPS or SPS corals.
The Kessil A360W is 90 Watts with an effective light greater than a 250 watt metal halide while the Kessil A160WE is 40 Watts.
Now some of the the negatives, based on the known science of lighting:
- The adjustable feature that is cool to most aquarium keepers is also degrading to effective PUR, as while it is nice to have these features from our perspective, the simple fact is what you or I might like is not often what is the optimum PUR.
In the end you are much better off with a fixed PUR spectrum set from the factory.
- The amount of energy wasted as heat is still high due in part to its features such as use of tuning without PWM, hence the need for a cooling fan. This is also why the Kessil A360W only replaces a 250 watt MH when higher PUR per watt, Other LEDs can accomplish this with half the wattage.
- Kessil Warranty = 1 Year, not very long for such an expensive LED
*E.Shine, Stark LED:
E.Shine often does not sell directly under their name, rather they market to retailers and distributors for their own branding.
Stark LED (distributed by Sea Dwelling Creatures of LA) is probably the most common marketer of this LED Fixture.
While E-Shine has updated their emitter bins, they remain behind the industry leaders as E.Shine utilizes common “binned” Cree & Bridgelux emitters, often a generation or two back at that.
In fact even E.Shine’s own web site admits that the older generation 3 watt CREE XG used for their COOL WHITE Daylight Aquarium LED Lights vary from 8000~10,000K; not the exacting emitters used by high end LED fixtures that target specific nanometer wavelengths for the best PUR.
Reference: e-Shine 60 Watt Cree Classic LED.
Please note that these are cool white emitters. Would you go to the hardware store and place a cool white lamp over your reef tank?
These emitters used by E.shine do NOT maintain the peak PUR necessary for delicate marine life, and instead have much more wasted yellow and green wavelengths due to use of cool white and green emitters.
It is also noteworthy that ALL E.Shine LEDs require a fan, some more than one at that. A proper driver along with PWM does not require a fan due to better control of voltage between the emitters, notwithstanding, spikes in voltage which decay PUR show up as excess heat!!
Also please read this article:
PUR vs PAR in Reef, Planted Aquariums Lights
E.Shine does a great job “pushing” these LEDs on companies looking to sell a nice looking product at a VERY good mark up, as I know of a friend in the business that gets these LEDs constantly marketed to him at prices that would allow for much better margins (since the emitters are low cost generic Cree emitters). However he has rejected these out of integrity to sell the best generation LEDs, even if the profit margins are lower.
One plus is E-Shine has increased their warranty to 3 years for most fixtures. From input of those using these products longer term, e-Shine has basically used the same design and technology, keeping development costs down while also improving quality control, thus the better warranty.
In the end with eShine, you get a very energy wasting, but still reef capable LED of older technologies, and with a good price and good warranty.
Stark/e-Shine Warranty = 1-3 Years
*Other LED Aquarium Lights (such as the Boost LED, Orphek):
There are many other LED lights coming fast onto the market, occasionally excellent, many good, many not so good, some a downright rip-off!
Knowing about what makes for correct Aquarium Lighting is quite helpful in making an informed decision.
Please reference: Aquarium Lights Facts and Information- Correct lighting
I would also stress that even among the more effective new LEDs hitting the market, such as the BoostLED, these all have to compensate for inferior emitters with high amounts of wattage used, which in my humble opinion defeats a primary reason to use quality LED lighting for your Reef or planted freshwater aquarium; lower electrical consumption per output of useful light energy!.
Using 4.5 times the energy (wattage) to produce only 30% more PAR, as in the BoostLED versus other tech, makes little sense to me or most aquarium professionals I have spoken with seeking the best lighting for their clients. This “shotgun” approach to aquarium lighting defeats the reasons to use LED lights [energy savings], one might as well use a good 150 Watt Metal Halide rather than a 135 Watt LED.
A Few decades ago, the “shotgun approach” is all many aquarium keepers of high light planted or basic reef tanks had as per comments by a 35 plus year aquarium professional I interviewed. So using eight 48 inch 40 watt “cool white” T12 lights to light one 60 gallon aquarium was sometimes necessary, but this is not necessary with many modern lights, so why go backwards when the technology is here?
The Orphek Nilus 120 watt LED light contains 60 LEDs in 90 degree lenses running at 2 watts each within a 24″x 6″ x 2″ housing.
This LED has (4) innovative “True Violet” 380nm – 420nm emitters (excellent for 30″ + tanks) as well as (4) 640 nm red emitters (which are nice for coral color aesthetics, but little to no effective PUR use in tanks over 18 inches of depth).
Other emitters include (3) 14,000K-16,000K White emitters and (22) Royal Blue 450nm – 470nm emitters
This LED is quite expensive (over $800), however it is designed for tanks over 30 inches in depth [replacing Metal Halides]. The overall color temperature is about 16,000k.
The spectral range is greater than the common Cree or Luxeon LEDs used in many LED fixtures, starting at just around 400nm (violet) and spanning all of the way to 750nm.
This is a top notch LED Aquarium Light for deep reef tanks, however I do not agree with a couple aspects of this design of this light and that is its emphasis on CRI (Color Rendering Index), as this is more important to what we see and not what the symbiotic zooanthellic algae within corals actually require. As well the Orphek white emitters are 12000K to 25000k leaving out much of the essential near infrared.
Please reference: Aquarium Lighting; CRI (Color Rendering Index)
While I realize that the popular fad of fading/dimming LEDs for sunrise/sunset is simply that; a fad as there is no scientific basis that this aids corals, I also do not agree with Orphek’s use of “blue” lights for moon light phase, which is also just a fad with no scientific basis in fact.
So once you get past the hype, this is still an excellent LED for those with deep tanks that may otherwise use a 400 Watt 20,000K MH, assuming you can even obtain these LED Aquarium Lights, however based on Orphek’s own data, this is NOT an LED fixture for tanks under 24 inches in depth
LED REVIEW SUMMARY
Emitter bins used in LED Lights are improving rapidly, although I am sure at some point these will hit the technology ceiling.
In the mean time, one can be certain of one thing, the best emitters are going to be licensed/patented and one is not going to find these in many of the cheapie knock offs. Even many of the “better” LEDs may use the newest emitter bins, but these are still “over the counter” emitter bins meant for many uses, not necessarily aquarium lighting and these bins generally aimed at higher CRI rather than the much more important PUR.
Another issue is that some companies are practicing patent infringement to close this technology gap. Purchasing these LED Aquarium Lights is not only a moral decision, but also many of these “stolen technology” LEDs are cheaply made and once these LEDs are legally closed down, the person who did not care about the moral issue, will likely face the problem of a light that fails to work long term with no customer support. This will result in these knock off LEDs being useless and not the bargain one might think when purchasing.
Finally, also realize the most important light measurement is “Useful Light Energy” or PUR and although I recommend the use of PAR Meters as a measurement of any aquarium lighting fixture, in the end this FAR from 100% accurate, especially when one considers the emitter bins used, and useless PUR emitter colors such as green. Often the “cheap” LEDs produce considerably more useless green/yellow light and are bottom heavy in the Blue Spectrum.
So, consider whether your so-called “deal” of a LED Light is really a deal at all or look at it this way: would you use multiple LED Flashlights you can purchase at Walmart to light your Reef or planted Aquarium? Although this analogy is a bit exaggerated, it is still a reasonable analogy when one considers current technology advances and the costs of developing these advances.
For further Aquarium Lighting information, I strongly suggest reading this long, but in depth article:
* “Aquarium Lighting; Reef, Planted, More”
While making recommendations, if your aquarium has a UV Sterilizer for Disease Prevention and Redox Balance, I recommend changing your UV-C Bulbs every six months for maximum performance and this and this is the place for premium UV Bulbs:
