Two things tend to burn out lamps early, water and vibration. A leak
somewhere will provide the water. You want to eliminate that. Vibration is
also possible. Is that light near some sort of equipment that may vibrate,
like the garage door? I suggest you may want to try a CF (compact
florescent) or garage door lamp. Both tend to handle vibration better.


Regarding your using the term "burn out"...

I concur with the vibration part, but how does water cause a bulb to
"burn out"?

I can see water corroding electrical connections and maybe those
connections would cause localized heating at the base of the bulb which
could even melt the soldered joint at the base tip and disconnect the
bulb, but that won't make the filament "burn out" will it?

A better term to use have been "fail", not "burn out". G
