Lumex Expands Sunbrite Family of General Illumination LED Products

An LED’s power conversion (wall-plug) efficiency varies inversely with its optical output power. Wall-plug efficiency can exceed 100% at low applied voltages and high temperatures. The laws of thermodynamics were not overruled. The "extra-power is provided by vibrations in the device’s crystal lattice due to the high environmental temperature.
