I have 2 lights on a photo sensor, set up parallel 120 VAC. The one closest to the photo cell turns off if I use electricity on the same circut. (I used a power drill / saw on an outlet coming of the same breaker) It also turns off if I turn on other equipment that isn't even on the same panel, and comes in strait from the breakers outside. I think it's 480VAC. Is there anything that would cause this other than the light fixture being bad? They are quite expensive and I would raher not buy one to find out that is not the problem.
It's not a nightlight they are outdoor flood lights.
