Do any of you recommend this light for UVB? Is it a tube light, or a bulb?
I prefer a bulb for UVB if possible since I already have the round dome, but I don't have a hood. I've been using a bulb that says Philips Colortone and it's blue, but I don't know how old it is and how long it has been used, so I want to replace it.
