hooked up two 155w chinese leds on my 75 g standard size tank tonight. for the price I think these things look awesome exspecially compared to the pc lights I had on there. I have them 12 in from the water and I'm getting gd coverage like this. can anybody tell me how much I should turn them up at first and how often or how high I should turn them up too, so I dont burn up my coral. thanks

30% wear they are now Is fine. ramp it up 5% every week until you hit 75 or 80

Yeah are great bang for the buck :)

Using one on our fuge right now. Also using a 60" long one on our frag tank. Just wish I could put the long one on a timer... can only turn it off with the timer. Have to turn it on with the remote :(
