I have 3 of their fixtures right now. A 2 bulb, a 4 bulb w/moonlights48" and a 6 bulb (actually 12 bulbs 6 rows) 72" w/moonlights. I really like mine, I have the 4 bulb on my freshwater and the 72" on my reef tank.
I have a problem with the moonlights on the 48" but I called customer support and they were super nice. They had a problem with a batch of the leds so they are sending out new ones to me at no cost.
