Part of the solution.
Let me see, those LED spotlights are something like 180 watts equivalent each. I think there was a typo in the original listing. I offered $20 and they’re on their way.
I am curious about the concept of “white light.” I don’t mean white-colored light, I mean white light as in white noise. My two problems are I don’t like the light in my bedroom and I don’t like driving up to or even seeing my house and yard light up by a light maniac. I’ve done some serious experimenting with lighting trees (because I think they are amazing). I have some beautiful—people call them rock outcroppings, I call them cliffs—things to light in my backyard. I’ve never been one for lights; in fact, I prefer it dark.
Just suppose I light up the things in my yard that I want to see. Will this alleviate light pollution?
In the past I have not had much success with white light. It did not seem to block the incoming light and the neighbor and police had a hard time dealing with it. Brighter and bigger may cause a problem.
Remember, your enemies have not won until they change who you are. Ordinarily I would pay close attention to the property line when lighting anything. Now I know A LOT more about that subject.
