Depends on what Watts the light is

the best way to tell is the hand test put your hand under the light if its to hot for your hand its to hot for your plant Start her around 24" away then lower her every couple of days if you want to be safe most say 18" is the perfect spot


All the best

Distance could vary depending on factors such as is does it have a vented air cooled hood and vented?
I would start at 500w @ 18 inches and see what you get for temps at the plant level.
