I will try to add photos later- but - here are the exact led’s

They have been up for about 2 years now. We used light weight wire to marry all the strips (which are adhered to the inside of the door, so around the glass basically facing in towards the shelves) and ran the wires on the under side of each of the Billy faces (that lil on the bottom?) and then all plugs (I also keep my video games on there) are behind the electric fire place which is only like 6 inches deep. So you have some good space back there, and the fire place actually vents out the front so no additional heat is in the Billy. - hope this helped.

So if you are aiming for results and not just a fun learning project, then I would simplify some of this.

The WS2812 style LEDs are great if you want to have every individual light be individually addressable (like having animated light strips). However in this case you really just want a static white light (probably dimmable so you can tune power usage) so you can get a simpler and cheaper strip like this. This would also free us from needing a more complex controller like an arduino. There are usually also varying degrees of waterproofed strips depending on how exposed you expect these strips to be.

These should include a controller so you can set the brightness to something reasonable (you could usually go 1/4 or less the max and still be plenty bright while saving power).

Since you want it to turn on at night, you can get a photo sensor that automatically trips on when the ambient light level drops below a certain amount.

Note that these are actually all using 12v power. You can either just power it off a 12v deep cycle or use a step up converter to boost what are probably 5v lipos. Also make sure you size your components and wiring for the total amp draw of your lights. I suspect a chicken coop is quite small, but I am a city boy and don’t know any better. But basically if you are using a single strip or less, the you are golden.

You could charge either battery pack off solar, but that depends on the solar panel and charger you have (and is it’s own can of beans).

This is all actually pretty similar to a light set up I did for burning man one year, and if I could get to work half drunk and completely heat exhausted in a desert, then I have confidence anyone can handle this if they give it a try.

These are the exact LED strips. They have been up for about 2 years now.

And the tv is up a little high- BUT- it wouldn’t make that nice straight line with the top of the shelves!!! And actually the room is insanely mis proportioned- like longer then it’s wide, but not by enough to make it two areas, so it works. Not great for my gaming… but it works.

We ran led lights strips up all the doors. The smaller doors (21 inxhes) are standard oxenburg doors that we took apart and cut down and re-assembled with out the dowels. The doors went back together so tight. Someday we will re drill the handles so they match 🤦🏻‍♀️

Here are the Led strips for those asking:
