It's interesting because I just set up a 24 gallon reef and I bought the Evergrow IT2040 LED's for lighting. I know they are the Chinese brand but they have 55 Cree 3 watt LED's. Full spectrum with the whites, UV's, Royal Blues, Blues, Greens, and Red. They also have full programmability. I liked the color(tried many different color combinations) but wasn't thrilled so I thought I would try the Kessil A350W. Really made a difference. The colors popped and you could see colors that the LED's didn't bring out. The shimmer is amazing. Also my corals opened up and responded better. The Kessil is set up mostly blue with a little white. I assume the Kessil is not as intense so corals will go slower but it sure looks nice. Also maybe since my tank is a little smaller the lower intensity won't matter as much.
