Configurable circuit layout for leds

A system for attaching a plurality of LEDs, the system comprising:

• a substrate;
• and
• a plurality of circuits that are arranged on an upper surface of the substrate and configured to accept a respective one of the plurality of LEDs,
• wherein each of the plurality of circuits comprises:
• a first set of electrical traces, at least some of which terminate at a first set of solder pads configured for electrical connection to a first sized LED;
• a second set of electrical traces, at least some of which terminate at a second set of solder pads configured for electrical connection to a second sized LED that is a different size from the first sized LED;
• a plurality of peripheral electrical traces for providing electrical interconnection between electrical traces of the first set of electrical traces or between electrical traces of the second set of electrical traces, wherein the plurality of peripheral electrical traces comprise a plurality of peripheral solder pads for mounting connection components to provide the electrical interconnection between the electrical traces of the first set of electrical traces or between the electrical traces of the second set of electrical traces, respectively,
• wherein the system is configurable to provide a first voltage and a second voltage to each of the plurality of LEDs.
