Does anyone's cooling fan ever come on? I have yet to see my cooling fan run in six weeks of running these lights. It is winter so the house is around 70.

Yes or house has been in the 60's and the fan does come on really quiet though.

I'm glad to hear I'm not the only one, this is a little bummer but so far I'm happy with these lights and I hope I don't find any future problems and reject selling my Kessil.
Mine does but is very quiet and I notice goes on for short periods of time when I run the light around 80%.

Review after half a year: I wish I didn't buy it.
1. It's UV channel is dangerous. One time I raised it by 10% at peak, and it burnt half of my tank. It was my bad that I didn't test for PAR when doing the change. Later I did test it, I found that, raising other channel by 10% raise PAR about 20~50 at 6" depth, but raise UV channel from 80% to 90% raise PAR by more than 80. Now I kept that below 70% at peak to be safe.
2. The sexy looking mount is actually very inflexible in practice. Because the angle of the arm is set, rising the light will also push it towards the front of the tank. My tank surface is 30" x 18". In terms of power, it's capable to give full coverage of the whole tank at peak. But that requires it to be mounted at the highest point of the mount. Unfortunately, that position also push it literally on top of the front glass. It's front edge is actually out of the front glass, and the back, where the top of rock is, is very dim. And if it's mounted lower so that it's in the center of the tank in its depth, it will be too close to the water than produce significant hot spot in the top middle of the tank. So now, I mount it at the middle level, put it on about 70% at peak, and have 2 Kessil A160WE, which I happen to have around, to cover two corners. For that setup, I wish I bought a A360WE at its place and it would do a better job and cost less.

NO3 is 0.5 at that time, with red sea test kits. PO4 is the lowest number the kit can read.

Wondering what depth is your tank? I have this led and don't have a problem with it. My peak is 70%blue and 50% uv on a 20in tank. I wish I had a par meter. My Sps seem to be growing fine but there not really bright in color. Wondering if that's because of the light.

It's 30"x18"x18". I mean the light is not that bad, I'm still using it. It's just that its mount limited its usbility. It could have cover my whole tank if it can be mounted in the position I needed it to be, and free up the two A160WE on it's sides. Keeping UV low is smart choice. I'm just disappointed that they allowed such dangerous channel exist on the fixture. It's like a noob trap. They should change some led from UV channel to blue ones.

I use my ethereal with one of preset programs until july 2016, i never had this kind of problem. YOu very low nutriment level, in case of ULNS you need to keep your Alk beteween 6,5 and 8 max. in case of your Alk is more than 8, the risk is to burn your coral. You can use Fauna marin color element to prevent this king of effect.
look this article, they talk about the burn
