Well, kinda technical question... Im planing on buying a nb-uvb canopy. I always thought the only danger with fluorescent lamps/tubes were in case of accidental breakage. But I've read a source that states that they always leak an amount while switched on.
"Uy said most people believe that mercury leaks only when the bulbs break. That’s true too, he said, but they also leak mercury vapor into a room all the time—from the minute they are switched on to the time they are switched off."

Other sources say they don't unless broken, but Im not sure now.
