Ive been working on a project to light a wall and am a little confused on powering it. It consists of 36 strips of 20 leds. The leds have a voltage drop of 3.3v, and require 20ma. I know how to power each strip individually in parallel with resistors. But, ive been looking around and see there is much cheaper ways. Ive been looking at Buckpucks but dont know what the total ma draw would be. Any suggestions on the easiest and best way to power this. Also Id like to power them all from 1 power source and dimming would be required. Thanks in advance for all your help.
