They do produce a good amount of heat, but you can take the whoel thing apart, leave the ballast in the box it comes with, take the light, add an extention cord so you can move it away from the ballast, because if the ballast gets too hot, it will shut the light off temp., and ya dont want that. Really east, take it apart, look at where the power hooks up and the bulb hooks up and put extention cords there, it will work wonders. Also you can get a CPU heatsink to put on your ballast to keep it even cooler.
