Hi... just got my first baby sully and am learning as i go. The pet store provided me w/ a coil uvb bulb which I returned per everyones advice here. I have purchased a reptisun 10.0 fluorescent tube bulb / fixture, but i am not sure if i need it? since I live in south Florida and plan to be outside often. I only have a 40 gallon enclosure right now, so I do not have too much of a cool side during the day when the 100w basking light is on. Does the reptisun uvb bulb produce heat? can you have too much uvb light ? Thanks!!
