I want to install a couple solar motion sensor lights on my run when it is finished. It would be handy if I have to go out to the coop at night as well as alert us to predators. I was wondering if anyone uses these and if so, do they work well and do they last a long time? I am planning to put the actual lights under the eaves of the run so they are somewhat protected from the weather and the solar panel on the roof, which faces south. We won't be having electricity run to the coop just now, so solar is out only option. Would love to hear your experiences. Thanks.
