I saw rope lighting was an option on Boaphile racks. A quick search of the interwebs found me a 30" (exactly the length I needed) indoor/outdoor white LED rope at Affordable Quality Lighting for $20 +shipping. After it arrived, I coiled it up in a Tupperware container and let it run for 6+ hours then temped it. I got 82 on the LEDs, and 88 on the resistors. The in and outside of the Tupperware temped the same as the ambient in my snake room (where it was plugged in). Pulled the back off the rack, cut a small notch to match the diameter of the rope in each shelf, slipped rope light into place, reinstalled back, and plugged into a timer on a 12 hour cycle. Took all of 30 min from start to cleaned up.
