Good point, If he bought the 5mm RGB LEDs 12v w/Resistors that come pre-wired he is good, if not than yep it's PITA. The COB RGB (Halos, Angle Eyes, Orbs) come with 12v resistors already. The LEDs pop up on Ebay from time to time 12v with resistors.. Luck of the draw on what color they have.
Robs lights had 4 RGB LED's on his main projector and they weren't bright enough for that big lens. Osiris and I were talking about this
Ultra Blue Devil Demon Eyes LED Strips Module for Projector Headlights Retrofit | eBay as a possible solution. It can be mounted closer to the main projection lens. The problem is the projector were you drill and mount the LEDs is almost 6 inches away from the lens. This little thing can slide under the housing just above the lens. Trying to do mine to see if it works good enough to recommend.
