Use a Humidifier, man. Get the rh up to like 50%.

I GARUNTEE YOU WILL SEE A DIFFERENCE!
As for affecting your lights, no way. You SHOULD have proper air exchange, which prevents that moisture buildup, especially since the lights are so hot anyway.

Again, check out any books by Jorge Cervantes or Ed Rosenthal.
Good luck, Dude!
