A Light Emitting Diode lamp is a solid state lamp (SSL)
that uses light-emitting diodes (LEDs) as the source of
light. Since the light output of individual light-emitting
diodes is small compared to incandescent and compact
fluorescent lamps, multiple diodes are used together. LED
lamps can be made interchangeable with other types, but the
presently at a higher cost. Most LED lamps must also
include internal circuits to operate from standard AC
voltages. LED lamps offer long life and high efficiency,
but initial costs are higher than for flurorescent lamps.
