I just put my Repti Sun 160 w MVB in a ceramic-based, 11.5 inch wide aluminum lamp. It ran fine for a minute or two, but I realized my lamp was much too high. I unplugged it, took it down while I lengthened the chain it is on, then hung it back up. Now it won't go on at all. I read that even slight vibration can blow out an MVB. Could I have blown it already with just that little bit of movement???!?!??
