They normally charge but my father in law retired from the utility company and called in a favor. :)
They aren't super bright but enough the neighbors might not like it, depending on proximity. My house is probably 100 yards or so from the arena and has a few trees between & it casts a small amt of light on my yard. Posted via Mobile Device
The only thing I can come up with is HPS lighting. I have two very small ones right now, but either I have them angled incorrectly, or they are not mounted high enough. We used HPS lights on the ski-hill years ago, I would have thought there might be something new out there by now. Maybe not.
