Yes you can but coil UVB bulbs are bad. Most are on the low spectrum of UVB which is the harmful forms of UVB and can cause eye problems especially in lizards. If you really want to use UVB, which I don't see as that useful for crepuscular snakes, I would go with something like a Reptisun 5.0 uvb tube. I personally use Reptisun 10.0 HO T5 tubes for my beardie but I don't use any UVB on my snakes except outside time during the summer where they ride around on me while I do stuff outside in my yard.
