You're going to get LOTS of opinions on this question...so here's mine. :D These don't look bad as knock-off eBay style lights go. I think they will probably grow coral just fine (some of your colors might not be as good though). They will not compare to setups like Radions and Hydras that are just better equipment as far as spectrum and quality of light goes. I know because I have some cheaper fixtures (1 from eBay and 2 from another company), and they do alright for those of us on a budget (I definitely couldn't afford the more expensive LEDs when I was first setting up). I'm now in the process of upgrading my lights...but I don't regret buying the cheap lights first...they were what I was able to get at the time and grew my corals (SPS and all). :D

Hope this helps! Good luck!

The price in the link given by the OP is for 3 fixtures (ad says "3 FULL setups"), so I think they're good on price.

I only sold it cause i wanted to go back to T5 but then I switched again from T5 to LED.

There is a reason the good LEDs cost more money is that they are designed with much higher standards. As such the build cost is much higher, add in to that the R&D for the complex controllers many have and you can cost justify all but the most expensive mainstream LEDs. If affording mainstream LEDs is a problem you can always look at going the T5 route. It will cost more in the long run but a lot of people really like it and the best looking tanks I have seen that have LEDs also run T5s.

BTW the selection of LEDs in the light on eBay linked is insane.
The only blue LEDs in that fixture are at 460nm, between royal blue and cool blue. You need to cover as much of the 440 - 480 nm range as possible, clearly this fixture only hits one point.
There is a blend of whites including 3500K LEDs, which are way too warm for a reef tank and are likely to turn your reef tank in to planted tank. Anyone looking to archive a full spectrum using natural white LEDS uses 4500K - 5000K LEDs.
The use of UV LEDs (400 - 420nm) is not recommended. UV light damages all life and for that reason some people have UV based filtration, but you do not want it in your display lights. Violet is desirable 417-420 nm, but no UV.
With the warm white LEDs there is no reason to use 520nm, or 660nm, LEDs as the warm white already has plenty of both of these for reef keeping.

have you used it. No so you really have no backing to what you are saying. the light works good. it has really nice color and make corals color up and do just fine. But use what you want. for the cost its a pretty good light
 
Up to a point you most always get what you pay for.

I could not imagine this fixture in a closed canopy being thermally stable. On top of a tank open maybe...Spent $7 on a fan and the heatsink temperature drops well over 30%...

The Bridgelux knockoffs do grow coral but there are better more efficient LEDs that offer a more complete spectrum to tweak the look of your corals.

More often than not with any thing in this hobby if you go affordable aka cheap it will cost you more in the long run.

Spending $1500-1800 on a setup that lasts over 6 years or spending $400 after shipping on one that lasts 18 months...Its close but also factor in the higher electricity due to inefficient LEDs and the hassle of repurchasing.

Just food for thought.

I've got 5 Chinese LEDs from eBay over my 210 sps dominated tank. It's hard to tell if there better or worse than the name brands because i don't have one to compare to. But my growth and color are booth fantastic! I've had them for over one year. In the future I might try a name brand such as ecotech LEDs on one half to compare them.
