I personally have purchased the 48 inch model of this light and used it prior to getting my hydras. Current led strips and this light are a well respected economy option of lighting in the hobby. The color blending is great and the actinics are awesome and will make your corals pop. Also the built in mounting brackets really create a plug in and play light with no hassles. The programmability is also easy. There are three modes that vary intensity through out the day I always kept mine on mode 3 with the highest intensity. There are two main problems. One is coverage. One unit over my 48 I felt like it worked but the spread was not enough to cover from short to back. Granted I had a bow from but I feel two would have been a better option. The second problem is the power. Like I said the color is awesome and I kept anenomes, zoas, Lps, and other soft corals. If you want to care for SPS these lights are out. So if I was an lps guy and had to rate this light 1-100 a 100 being the bet I would give it a 75% considering price, power, and coverage. The controllability tho is honestly Amazing for a light and controller at this price.
