I’m building a Custom set of Headlights for my 2001 F250. I am adding 20 RGB LED’s to each headlight. I will be connecting them to a Morimoto Bluetooth Controller.
Spec for the RGB LED Bulb: Forward Voltage / Current: Red:2V-2.2V Green:3V-3.2V Blue:3V-3.2V | 20mA (each color)
I split the difference for my calculations I.E. Red:2V-2.2V I used 2.1V and Green:3V-3.2V I used 3.1V. I also used 14 volts instead of 12 volts because my truck is putting out 14 volts when running.
I am planning on putting 5 sets of 4 bulbs in the string with appropriate resistors per color.
4 Bulb Design Red
4 Bulb Design Blue & Green
Do these calculations for the 82 and 300 ohm resistors look correct?
