you can use your black light but it most likely won't give off much heat
Nope, Thats not true, they give off alot of heat. Believe it or not, but a 75 watt black light gives off a ENORMOUS amount of heat for a 75 watt. The only disadvanatge is it doesnt project the heat down as much if you dont have a dome light. Other than that they are fine, and it gives the bp a sence of night, alot of ppl recommend a black light. but i found from when using 24/7 they tend to burn out alot. But with a price of 2-3$ it all makes up for it

Hope that Helps
