The majority of high power white LEDs is designed to be ran at 350 mA constant current. This is because the chemistry of a white LED sets the forward voltage at about 3 V and 3.0 V x 0.35 A ~ 1 W, ...
In designs using multiple LED strings such as brake lights, daytime running lights, rear lights and other automotive lighting applications, current-balancing circuits supply equal current to all LED ...
