I have 4 outside. 2 work great during the summer sun, 2 are out all of the time. Unfortunately, I cant run AC power to 3 of them. So, during the winter, they are "out" more than they are on. We've repositioned them many times. One, the cord isn't long enough for me to position the solar panel at max. It usually takes a month for it to finally charge back up, will last two weeks, then blink out again. Oh and when they do work, they dont work, because it's too cold. ♀️ so I get a message saying "temporarily paused due to cold temps" or something like that. I live an hour outside of DC / Baltimore.
