* Note: On this light, the amber color slightly reduces the
useful light output.
A light-emitting-diode (LED) is a semiconductor diode that emits light when an
electrical current is applied in the forward direction of the device, as in the
simple LED circuit. The effect is a form of electroluminescence where
incoherent and narrow-spectrum light is emitted from the P-N junction in a
solid state material.
