Inexpensive lighting is easier to install them most people think
I found these Cool White LED panels on eBay for 99 cents
Here is a link to the auction:

You can easily attach some wire leads to these and power them with a 4-12vdc power supply and a simple switch.
LEDS are hard to break, as long as you don’t exceed the recommended voltage they will be ok. You hook the positive lead to one leg and the ground to the other. If it doesn’t work, swap them.
Once you figure one panel out, you can wire up the rest with red/black 26 gauge wire.
You could light an entire display for less then $20
Here is my War Machine cabinet with full custom lighting:
The shelves have 36” LED rope lights and I replaced the 120VAC halogen lights in the Pucks with the 12VDC LED Panels.
Then I removed the plugs and connected them to a 3.7VDC cell phone power suply with wire nuts.
The center is still Warm White Halogens, so you can see a huge differnce in the lighting.
I could make some inexpensive lighting kits and sell them on this forum but I’m not going to pay $35 year to make a few bucks selling something that is very easy to make.
