...back of my house? My backyard is so very dark and someone keeps unscrewing the motion lughts on my garage. But what is a reasonable watt for an outside light, as the 60 watt that has been in the light for the last two years that i have lived here has never been an issue. New neighbors however, seem to enjoy jumping the chainlink fence and twisting it so it stays off all night. Why they think its ok to tresspass much less mess with my stuff is beyond me, but I leave it on before i go to bed which is super late, and they are outside all night doing whateber with their loud music and big bonfires. My husband is currently serving our country and I had thought I had just as much right to feel safe in my home with it just being my son and I. Just wondered, thanks!
