I have four solar panels with two lights each on long wires. There are four lights in the rabbit colony, one in the feed shed, two in the chicken coop and one in the turkey shed. They turn on and off at the panel and on the light itself. I think they are made by Noma, you get a solar panel and one light in a box and you can buy a second light separately. I have had the oldest one for a few years now and it still works great, deep cold in winter, heat in summer, no problem. I don't recall even having to replace the batteries in any one of them yet and the lights are very bright. I have had a problem with the switches on a couple of panels and a couple of lights but it's an easy fix. Along with four solar spotlights, my set up lights up like a little city block at night. I also wear a battery powered head light made by Energizer, it has two intensities of white light, a red light and a green light, it is the single most convenient item I have ever bought.
