Growing coral like crazy over here. I believe the red and green LED were causing algae issues per some saltwater boards I belong to. So I switched them out for some UV and 20K white. Hopefully that helps. But seriously, this will grow anything. Buy it now. Forget those crappy 100$ "Reef" fixtures, Chinese LED are the way to go.

I am overall very happy with these lights. I purchased them as an upgrade over my 29 gallon mixed reef and wow do they kick out a lot of light. I run whites and blues at 30% and am seeing good growth of SPS that I have in the top half of the tank. I did have an issue where one of the drivers went out and half of the fixture's blue LEDs would not dim, however I sent a message to the seller with a description of the problem and they rapidly diagnosed the issue and sent me a replacement part free of charge. I would recommend suspending the lights higher than I have (~4 inches above the tank) as there is some color separation of the LEDs on a couple spots on the rockwork. All in all I am very happy with these lights for the price point, and believe that they are fully capable of being the only lighting for a successful and attractive aquarium

Have these on my 150 reef tank. Corals seem to like them Have SPS and softies, and a couple of clams. I have 2 of these lights that seem to be enough for them to look good the growth is not bad but not as good as i think more expensive lights might give you

I really like this product. The suction cup for the outer display doesn't stay well but nothing a little super glue can't fix. Accurate or near accurate readings. Must have to get water for WC to right temp and fast

Really like this light, very bright, good color rendition. Simple controls, just use regular timers. I picked this one because the ones with electronic timers don't hold the settings if there is a power failure. My only recommendation is to open the fixture and remove the lenses. They come off easily. The lenses focus the light way too much, make hotspots and rainbow effect, and kept the light from covering the front and back of my aquarium. Without the lenses the coverage is greater, with more even lighting. The lenses are used in all the fixtures, so it's not unique to this brand. Love the light. And fans are fairly quiet.

This is a very powerful LED. When I put it on over my rbta's they all closed up. I have to slowly acclimate my tank to this light. The only thing I'm concerned with is the fan only goes on when the full spectrum is on and not when just the blues go on. Doesn't seem to be too hot, but time will tell if it lasts. Good value!

Works great! Accurate temperature & nice design, really like the way it looks! Suctions to the tank so I can easily read temperature of the water. Would definitely purchase again and highly recommend if you are looking for an accurate, sleek thermometer.

The coral growth and color this lift gives my tank is crazy makes me want to return the SB reef light I put on my other tank 😑

So far the lights are what I expected! Still waiting for electric bill to compare the difference with the metal halide!
