the compact uvb bulbs are supposed to be pretty bad healthwise, reptisun 10 striplight is whats usually recomended im sure someone else can be a bit more in depth
also what are the basking temperatures etc.
It's safest to go with a Reptisun 10.0 or a MVB.
The compacts, coils, ESU's, some of the Reptiglo bulbs, an any generics can be harmful to your beardie.
