Here you go, friendo.
Can’t speak to it at all but it was fairly easy to find. I’m sure there are other like this you can shop around. This was the cheapest I found.
I'm also not aware of programmable individual solar-powered lights.
I have a decent-sized solar system on my coop, and 12V LED lights for coop lighting. I have 200W of panels and 100 Ah of battery storage, because I also have a automatic coop door, a solar heater, and eventually an electric fencers. That said, I have a 24x24 building and 100 hens.
I don't have a timer yet, but I could get a 12V timer if I thought I needed one. They are $12 on Amazon.
Is your coop somewhere where you could run AC power? I didn't have that option, which is why I invested so much in 12V and solar.
There’s lots of things like that:
