My little coop has no power and I need to extend the daylight for the layers. Solar Lights seem like they could be a great low hassle solution. One trick is that we live in WA and our winters are not the sunniest, and I would need to get a light that can put out about 5hrs of light per day and then re-charge under cloudy conditions. Our coop is ver small, so I don't need a massive output for my little space. Figured someone on here has done some homework on this and could recommend a few products. 12V LED systems seem like they might be a good Solution.. Thoughts? thx.
