I was at one of our LFS the other day and the Red Sea rep was there demoing the light for them. Of course me being me, I stepped behind the counter and listened lol.
Supposedly you cannot burn your coral with them, provided the directions are followed. They have done extensive testing with the lights over numerous tanks, with crazy flow, calm flow, etc. This allowed them figure a par average based on numerous studies of different tanks. So per the reps wording, follow the directions and you should be good.
As for cooling, they have fans. The fans are near silent, even with the light on for over an hour at 100%. The heat sinks were warm to the touch, but not like you could not hold the light with it on and running. I even touched the inside of my forearm to it, and it was only warm in that aspect. Hands are not the greatest indicator of actual heat for me lol.
Color and spectrum was very nice, even on some of the presets he demonstrated. The cloud feature in some of the presets was nice as well. Seems like you could blast some SPS, but throw in a cloud here or there to give them a break for a few.
As for spread, the lens they use actually does a nice job of distributing the light.
For pricing, he was very tight lipped on it. The only comment was "It will be in line with other higher end leds." I did poke him about if he was referring to AI and Kessil or the Ecotech Radions. He just looked at me and gave no answer lol.
