Today I spent several hours preparing for my installation of LED tape lights. I bought four reels of these:
Each reel is 16.4ft and consumes only 45w of 12v DC. The power will be supplied by two 100w Drivers. I wired the drivers in parallel and will connect them straight to the house current 120v AC.
The left driver (below) will supply power for the front and right sides of my layout.
The right driver(below) will power the left and back sides.
