I did something like that for my Lego shelf. Used some LED strips and a motion sensor module to keep it all automatic. I had no idea what I was doing and bought a bunch of stuff I didn't need, but...
And if you're comfortable soldering, that's pretty much all you need to get something up and running. But I wanted to make it all modular so I could take it apart and set it back up without too much hassle. So I ended up buying adapters and coaxial power cable things:
I'm pretty sure I did it as inefficiently and cost ineffective as possible because I have severe amazon impulse control issues and just buy shit to get started on fun projects. I'm sure with a little more research/guidance you could do it a little cheaper. But I'm happy with my setup for now.
and here's a picture of the shelf. The shelf is terrible, and it's all a wreck because I'm in the middle of moving, but it shows the brightness pretty well. Oh and I have about a 1/4 roll of LEDs left, so I'd guess 2 or 3 rolls would take care of your shelf.
i bought these LED strip lights, which can be cut down to whatever length, and this power supply. i also bought some extra wire and connectors so i could run one long strip of LED lights through all four enclosures. worked around the adhesive issue by hot gluing the fuck out of them. i scratched up a line about two inches away from the front wall, to create some texture for the hot glue to grab, and allowed some extra glue to sort of wrap around the strip and prevent the strip from being peeled away from the glue.
Hey OP, instead of keeping the info in chat I'll post here so others might be able to use it.
I'm assuming you have no experience splicing wires, soldering, or using heat shrink tubing, so I found some quick connect things you should be able to use.
So, the parts I have here are the LED Strip (marked as 'sections' since you will be cutting it), the L Connectors, the 'Wire Harnesses', the Adapters, and the Wire itself.
I drew up a small diagram here with explanation.
​
If you, or someone you know would be able to do the stuff mentioned above, this could have a lot less parts by doing aware with the adapters and wire harnesses and just soldering the wire between LED strips.
(Maybe there is a local Makerspace near you that could assist)
​
Also, instead of the LED strip method, I've seen people with LED bars the run the length of the shelf, and have wires to connect up to another bar. Something like this. (search" LED under cabinet lighting")
If the above diagram seems too difficult, or you're not able to get anyone to assist, then this would be a super easy option for you.

I was running this at 2.5 amps without a heat sink but it will take much more if you have a fan or heat sink. 18 gauge wire will do fine with some headroom (1mm if metric). 20 gauge wire would normally be fine but low voltage wire can come in a connected pair so they are derated. For example, this 20 AWG wire pair is being derated to 3.2 amps by the manufactuer although the current-wire size charts would normally show this wire to be fine. That wire would be fine for 30-35 watts on this LED and the same wire I used on my testing.
Buy this 18 AWG wire:

Keep in mind that this is a constant voltage setup that you're likely doing. 12.6 volts and 12.8 volts can have a significant difference on current levels and how hot this COB gets so you want to actually measure the current level. Different COBs can have different voltage drops and COB temperature also plays a role in voltage drop and thus current levels in a constant voltage setup.
