diodes that emit light. I'll give you some links to explain the real
physics behind it if your interested. The real beauty of LED light is
that it transfers electricity into light in the most efficient way. A typical
incandescent light bulb only transfers about 10-20% of the energy it
uses into actual light, the rest is in the form of heat. LED bulbs
transfer 100% of the energy used into light.
Most people think of LED's as the little red number displays on a
calculator from the 1970's. LED's have come leaps and bounds
since then. This is especially true in the last 5 years or so. With the
introduction of super bright LED's into the market it is now possible
to use it as a form of useful light. The only hinderance is the price at
the present time but even that has come down to the point of being
affordable.
