A device for an LED has a substrate and a circuit on the substrate configured to accept the LED. The circuit includes a first set of electrical traces terminating at a first set of solder pads for a first sized LED, a second set of electrical traces terminating at a second set of solder pads for a second sized LED different from the first sized LED, and peripheral electrical traces for electrically interconnecting electrical traces of the first set of electrical traces or between electrical traces of the second set of electrical traces. Connection components electrically interconnect the first set of electrical traces with each other or the electrical traces of the second set of electrical traces with each other, respectively, at corresponding solder pads. The device is configurable to provide a first voltage and a second voltage to the LED.
