bulb placement

[raycopp]

What is the best height to place 250w 14k bulb from the top of the water.

Thank you

You want the light to cover the entire area you want lit but you have to be careful with heat issues and also the occasional splash can do damage to glass parts around the light.

I like 6" or so.

I have my 250's 8" off of the water.
