MVB troubleshooting

[KeithC]

Hello all. I just started having trouble with my MVB. I replaced both the bulb and the fixture but now the new bulb starts flickering on and off as soon as it heats up. Any ideas?

Edit: I'm using a Solar Glo 125 W and a Flukers 160W fixture

the best advice i can give you is get rid of the MVB, especially the solar glo. ive tried multiple MVBs before, and even the megaray crapped out on me within a month. the only lighting setup that is completely worth getting is a reptisun 10.0 tube and a regular basking bulb. trust me, youll go through too much time and money trying to find the perfect setup like i did. im just trying to save you the hassle. hope this helps and good luck

Do you have the Flukers sun dome or an 8" diameter dome? What I have found is you need to have a 10" dia. dome so the bulb does not get to hot. And the dome should me mounted to a spot that does not move on the viv. Ounce I got the big dome mounted on my viv and stopped using my x-10 system to turn on and off the light the MVB became reliable and lasted a year. I have my light pointing straight down, I really do not know if that makes a difference.
The MVB are a pain because the mfg. do not give enough info on how to use them. They cannot be treated like a regular spot light, but they do solve some problems like getting the UV light where you need it and can save money by not needing to be replace as often as a fluorescent tube. My viv is to tall to have a fluorescent tube within 10 inches of my animal other wise I might have gone the Reptisun route as they seem to be more consistent in uvb output.
