UVB Lighting- An Absolute Essential For WTFS?

[Mentat]

I added a small UVB tropical CF bulb on Duncan's (mini GABF) enclosure last Spring and after couple hours exposure he moved away from it and took cover under some silk plants. Moved light to corner farthest from his hanging off area and that appeared to be OK. He seems not to care about it being on or off a few hours every day .

That's interesting, none of my greys ever moved away from it, but Atlas seemed to have a burn like mark on his head last spring after getting new UV bulbs. (Before that, he was in QT with just an incandescent on the tank.) I thought it was from an incandescent that I used to heat, but even removing that, the mark was still there. When I switched to LED, it finally healed up. Made me wonder if the UV was too strong for the size of tank and the greys. None of my other 3 ever had an issue like that, but Atlas slept as close as possible to the lights, where the other 3 kept a bit of distance from them.
