@gunrunnerjohn posted:No resistors needed Stan, if he has two greens in parallel and two red's in parallel, he can just put those in series/parallel and use the LED regulator board.
When you say series/parallel do you mean connect the red (+) of the RED LEDs to the (+) 20110 LED Lighting Regulator, then connect the black (-) of the RED LEDs to the red (+) of the GRN LEDS and then finally the black (-) of the GRN LEDs back to the (-) input of the regulator? No resistors needed? Similar to the diagram below?
