LED
Emission of light caused by heating the filament (bulbs.com)
Replacement for incandescent or halogen lamps.
Two types: screw-in & plug-in.
Screw in lamps are self-ballasted and can generally be placed in an existing screw socket without any additional equipment.
Plug-in bulbs require a ballast and a socket that corresponds to their specific base configuration. (bulbs.com)
Utilize light-emitting diodes in order to produce light.
“Solid-state” technology, which means that the materials used to generate the light are encased within a solid material.
