Hi,
I am setting up a 100 LED lighting system, i'm going to use a computer PSU 3v rail to power them. I don't want to solder individual resistors to each LED so what size resistor would I need to run all 100 safely? i'm thinking about 0.5 Ohm, 10W wire wound? Or is this completely wrong? Or is there NO need for resistors when using this type of supply??
LEDs are 75mA MAX , 3.0v supply.
