dusk to dawn light over garage

I too have had some problems with a dusk to dawn light over my garage. I placed an energy saving florescent bulb in this fixture and it worked great. But the next day I found glass where the bulb apparently busted and the ballast that are built into those types of bulbs was all burned up. Someone told me it was probably because I put a bulb with its wn ballast into a fixture with a ballast. So I installed a HPS bulb& it didn't work then I installed a MH bulb and it didn't work. At this point I figured I burned the ballast in the fixture up but before replacing it I installed a plain flood light and it worked. SO I am guessing my open bottom dusk to dawn fixture has no ballast?

RE: dusk to dawn light over garage

you are listing different types of fixtures, i was not aware a fixture would accept those varied styles.

as far as "Someone told me it was probably because I put a bulb with its wn ballast into a fixture with a ballast." a regular d-d fixture does not use a ballast. the reason your CFL burst is that it was not designed for this use. you need a CFL flood light that is made for outdoor inverted use. most regular CFLs will overheat and fail when installed inverted.

The broken glass also makes me think water got to it. Even if protected from rain...fog or dew will do it.
