I finally got brave enough to knock out all of the wasp nests that were in my porch lights. I haven't been able to change the lights in there for a while, but since I wanted to try these out, I had to bite the bullet and clean out the wasp nests. Well, I got them in tonight, and I wish I had done it long ago! There are a very bright white, which I like. I can leave the light switch on knowing that when the sun comes up they will turn themselves off. I wish I had done this sooner......
