I wanted to replace a very power-hungrey combination blue led ... fluorescent tube ... ballast-driven metal halide system. I wasn't feeling all that confident in the amount of light I'd get from the 48" version of this fixture, but I was (quite happily) wrong.
Not only is it as bright as I could have hoped for, the eight blue moon LEDs are also high powered, illuminating the tank nicely; I'm sure the coral will react to this more than the puny little LEDs in my old fixture.
Interestingly, there is some UV (ultraviolet) light emission from the blue LEDs, and my mushrooms fluoresce a beautiful green color. I don't know what to think of this in terms of good for / not good for the coral, swimmers and crawlers, but it sure is interesting. Looking around on the net didn't really illuminate (sorry) the issue, either. As a side note, UV emission is common with blue leds. With LEDs as powerful as these, I guess I shouldn't have been surprised, but I really hadn't consider it beforehand. So now you know, too.
I like the way the fixture sits close to the tank top glass. Between that, and the fact that the LEDs themselves and their lenses make them fairly directional (downward), there is much less "splash" light from this fixture than my old one. I consider this a significant benefit. It's easier to look into the tank without a lot of glare up above it.
I also appreciate the huge reduction in heat generation -- hopefully that'll change the amount of salt deposition and so forth I get from surface evaporation and splashing, but even if not, the fact that the fixture is easily handled means that it'll be much easier to keep the top glass clean even if the deposition rates are similar. I can't imagine they'd be worse... the MH fixture was HOT!
The fixture itself is very light and easy to handle, and the power supply, although a switching one, does not emit significant RFI, which would have caused me to replace it, as I am a radio operator and require a quiet RF environment. Looks like they spent some money there, for which I am grateful.
The timer came set to usable defaults (although it strikes me as odd that the moonlight is just an hour before and a couple hours after normal light... moon stays up all night sometimes, so... ? But I'm not changing it until I read up on that a bit more.
Setup was a breeze. Unpack, attach to the power supply, set it on the tank, plug power supply in, a short self test runs, and on it came. I set the clock --- trivial -- and was done. Well, if you don't count the work of taking my 40 lb MH/FL/LED combo fixture down. But I can't blame that on this product.
The only thing I would have liked to see was the power cord coming out of the same end of the fixture that the timing controls are located on. Instead, it comes out the opposite end. This means that both ends of your tank now have cords and etc.; previously, I had a "show end" and a "busy end", now I have two busy ends. Oh well. :)

I purchased this light strip and it stopped working after about two years. Due to the cost and the short life expectancy, I would not buy this product! It only has a one year warranty.

Rated 1 out of 5 by 1234567891011r Not really reef capable unless you have only low light corals and don't care about true color rendition
Fwiw I got this light ( 2 months old) with a tank purchase and gave it to a friend who needed to send his" real" fixture in for repair. I just want to leave an honest educated opinion of this fixture for those who will be lured in for the price of this unit compared to real reef led fixtures.. So if you read nothing else of this review please take note that this fixture is not really reef capable power wise and especially spectrum wise, it's a waste of time and money and your corals will die eventually under it. Should be labeled saltwater fish capable only due to par readings posted below.
This unit I feel is made for beginners who don't know any better and buy it to fill the void of not being able to afford a better option, so buyers beware there is a reason it's so cheap. I'm not saying cheap like burn down the house cheap, I'm saying cheap as in money wise and to boot does not work to grow coral other than mushrooms or extremely low light corals. My friends tank is all zoas and lps and this light caused serious stress on his tank, it went from thriving under a t5 fixture to a downhill spiral two weeks into the switch. I took par readings on the fixture and got 89 par directly under the water surface with my apogee mq200..So not only is it only white and blue they are only 1 watt let's that are most likely under driven with par readings like that.. In a standard 55g he was seeing a par of 18-22 dead center of the sand bed ( that = no corals living) he replaced the Bunk Marineland fixture with his original t5 fixture 8" above the water ( par reading of 270-300). A week into a proper fixture his tank was on a rebound and went back to normal in the weeks following
I'm not really trying to bash it to much as I'm sure it's safe for a fish only tank but my honest advice is save the money and buy a used fixture or spend the money on quality leds from Dr foster and Smith if you really want leds over a reef tank. You will buy corals that will end up suffering and withering away under this light so in the long run you WILL loose money compared to doing it right from the beginning.
Sorry for the rant but I just want newbies or people who don't want to research leds in general a true opinion of the fixture from someone who actually knows there are way better options out there and has been reefing for 20+ years =)..
Just searching the name of the light on any major reef forums will give you all the info you need fwiw..
