I have two on my front porch. The bugs don’t seem to be drawn to them as much as incandescents.
I guess the bugs don’t like the light either....lol. That is one good point though. I’ll have to try a couple outside.
I know they don’t work well with photo electric cut offs. My outside lights have these so they will shut down during the day. About drove a friend of mine nuts, trying to get it them to work.
