The LED series/parallel array wizard is a calculator that will help you design large arrays of LEDs.
The LED calculator was great for single LEDs — but when you have several LEDs, the below wizard will help you arrange them in a series or combined series/parallel configuration.

The wizard determines the current limiting resistor value for each portion of the array and calculates power consumed. All you need to know are the specs of your LEDs and how many you’d like to use.
