Like the other reviewers, I also hate this fixture. I've replaced the lamps three times in the past year, with the last two giving me about 3 days' life before blowing out. I returned from a short trip to find my driveway dark and insecure.The lamps always fail the same way - the internal structure just falls apart, leaving the filament intact but unconnected. My thoughts are that the lamps aren't made to be used base-side up. And yes, I know how to handle the glass envelope of halogen lamps - these were installed correctly. Like the other reviewer, the tiny flat-blade set screw that holds the lens assembly in place is tiny. While mine hasn't locked up, it is such a pain to twist around on a ladder, crane your neck under the eaves and find that tiny screw, not drop it and not drop the entire lens assembly.The upside are the small "eyelid" shades that keep light spill out of the neighbor's windows.
