your friend Bobby is right!
for UVB my preference is 5.0 exo terra reptiglo, either full spectrum or tropical.
there is another lamp bulb by exo terra that seems interesting to try based on a description, but I haven't seen it for sale yet. Exo Terra : Natural Light Ion / Deodorizing Bulb

Lija, this is the bulb I buy costs me about 28 euros but they do last a long time.

I used to get the all in one bulbs but they fail quite rapidly, specially the 100w/125w I used for my reptiles.
I think it is better to buy separate ones.
