AcanLighting 600 Series Prism LED

Hi,

I was wondering if anyone else out there uses these fixtures? I purchased 2 back in November for a 90g.

I'm having an issue with brown SPS and I'm thinking its possibly the lights. I was at a LFS and they had them over a tank and also said that they are having an issue with brown SPS in the tank

Curious if anyone else has had any experience with these lights. What the max/best intensity would be, distance from the water level, what has given you the best results etc...

Thanks

I'm the only one out there that uses these lights?
