1. A system comprising:
a power input; a first die comprising a first light emitting diode with a light emitting surface; a second die comprising a second light emitting diode with a light emitting surface; a third die comprising a first current limiting element, wherein the first current limiting element of the third die is electrically coupled to the first light emitting diode of the first die and the second light emitting diode of the second die, the first and second dies are electrically coupled to produce a combined forward voltage greater than a forward voltage of either the first or second die, and the third die comprises a first terminal coupled to the power input and a second terminal coupled to at least the first light emitting diode or second light emitting diode; and a planar substrate, wherein the first, second, and third dies are formed on one side of the planar substrate.
