Scott,

If it's a new home then call the electrical contractor who wired it..

Good point but I'd guess that this is a wiring hack job done by the previous
owner or his drunken jack-leg handyman using inexpensive devices purchased at
McLowesDepotBigBoxSuperMartHomeCenterOutlet...whic h explains why it's fubar.

After a few years even professionally installed sodium vapour lamps
purchased from first-line electrical distributors DO fail. About 3 of
the original 12 exterior floods at a 6 year old high end office
building are still functional. I've changed several of them - have
given up.

Not sure why you see frequent failures like that. Maybe your environment?
Our bulbs go on at dusk, off at dawn and last about 22,000 hours.
Winter lows are typically 20F and summer highs of 90F with lots of humidity.

Also, outdoor wire-nutted connections should be coated with appropriate grease
and oriented in the j-box so any water runs off instead of into the nut. (Think
upside-down coffee cup.)
