For your money this product is priced to sell. Surprisingly well built, stupid easy to use, runs quiet, and so far reliable. Had it for a month now running on a day night schedule on a simple timer and nothing failed. All diodes running nice and bright. Only thing I can pick at is the diffusion of light under 5 ft. Do I recommend it? Of course. Especially if you don't want to spend $1000 or more on a comparable fixture.

This is a good reef light for the most part. I have 2 of these over my 7ft aquarium. I bought one as a test subject to see how well it did with my corals. They seemed to like it so after 4 months I bought a second to finally ditch my t5 and metal halide set up. When I sit the two side by side there is a notable difference between the blues on them. The older one doesn't have has great of coloring as the new one. I do not know if the bulbs just became weaker over time or if it was because of 2 different batches of bulbs being used. Either way im not very happy. I run these lights at the lowest setting for 5 hours, then ramp them up to 30% for 5 hours, and finally go back to the lowest setting for 4 hours, before turning them off for the night. That Being said I do not believe these bulbs should become weaker when I've never ran them up to or above 50%.Read full review

This is the second of these lights I've owned. The first one is just about one year old at this writing, and runs like a champ. That one arrived with one LED out, and Mars Hydro's response to that situation was to quickly shoot me a little bag with a half-dozen replacement LEDs, which made removing the dead one and soldering in a new one pretty easy. This unit arrived (across the US!) in just about two days, and in perfect condition. For the price, nothing else even comes close - and these _do_ grow corals; in fact, they can be turned up too high for some sensitive or lower-light species! Would I recommend to a friend? I already have done, several times - and will again.

All around great light for a great price. The 2 power cords 1 for each channel make timing your actinic and full spectrum cycle very easy and the built in dimmers are simple and easy to get just what you want out of each mode.

The lights from China look the same. This one does to. But the inside is built better. Dimmers work even at 20%. Lights turn on at the lowest setting. Some of the others have to be turned up to 40% before they turn on. Then you can back them down to 10%-20%. Better light. Will buy again.
