So I'm planning on getting a 700ma 3W LED runs at 3.8V. I'm planning to buy a 21-38V 900ma (+-5%) LED driver.
Will this work if I want to run 9 LEDs.
Main question is can i get a 900ma driver for 700ma leds, I always assumed leds will draw as much current as needed. not sure the LEDs will draw more then needed and burn out.
