ive not long had Terri and not changed it yet but i hear its about every six months or so. i use a repti-sun 10, the only uv that is talked about by BD owners. hope this helps.

Yes, it's recommended that the UVB bulb be replaced every 6 months.
A great one to use is the Repti-SUN 10.0 (not to be confused by repti-glo).
I have chosen to use the Powersun 100watt for now, and have had no problems with it. I love it and my beardies do as well.
Good luck!
I use megarays MVB for my older guys and change them out yearly and reptisun 10.0 linear for the babies and those need to be changed out every 6 months.
Hi there a little update we went from a 50 watt heat lamp to a 100 watt basking halogen heat lamp hahaha I saw some comments about it being so close so I made sure to put it a ruler away from her
