are coming out lately, but few know exactly what they are or
what makes them different from other bulbs. In short, Light
Emitting Diodes (LED) are bulbs without a filament, that are low
in power consumption and have a long life span.  A Little
History  In 1907, a British experimenter, H. J. Round, was the
first to report of a light-emitting solid-state diode.
Unfortunately, this discovery produced no practical use for many
decades. In the 1970s LED indicator lights started to become
commercially available for use in appliances such as TVs,
radios, and telephones. Although these LEDs were bright enough
to use as indicators, they were not able to illuminate an area.
As the technology started to advance, the light output of LEDs
increased, and have now become brig
