Hi,
Most high power LEDs are run off constant current drivers, but is this really needed ?
Can a 0.5Watt LED be run using a normal safety resistor as long as the resistor is rated high enough and the LED has a heatsink ?
Are the only reasons these LEDs are run off constant current drivers because of varying input voltages and for efficiency ?
Thanks.
