Unfortunately, I lost my beardie last night. I'm at a loss right now and miss him terribly. Once I give myself proper time to grieve, I would like to get another scale baby, not to replace my Mushu, but because these guys are amazing little babies. Anyway, my question is, unplugged, and turned off, how long does a UVB bulb last? Or would it just be best to get a new one when I am ready for my new Lil guy? The one I have currently is a little over a month old of use.
