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.
I just set Swordtail's timer for his bath and paused it so I could actually fill his soaking bowl up and he crawled over my phone and canceled the timer
Mirage came out of brumation on April 26. He was doing great. On May 2 he started acting funny. We just redid his tank, and he keeps going into one of his hides. He just lays there. He shows no intrest in food. HELP!
