How critical is it that I use a UVB emitting compact florescent CFL bulb. Brands like Exo Terra have them and they are about 15 bucks each but I can get "normal" CFL bulbs for the light hoods for a lot less. If the BPs are typically hiding during the day (when the bulbs are on) and i have them near a window in Florida how critical is buying a UVB bulb? I was thinking of getting one 26w UVB and the other 3 "normal" ones.

Thoughts?
