In the last couple of years or so, I have noticed the rapid proliferation of
LED flashlights.  I purchased one about a year ago, and I was impressed by
how bright they are and long the battery lasts in these flashlights and also
the fact you can't easily break these "bulbs".  They also emit very little
heat.

In the computer industry, we have been familiar with LEDs for a long time
but they were always red, green or yellow.  I recently came across this
article which I thought some people might enjoy.

DOE.gov shows that in the US about 9% of electric consumption is for
lighting.  I don't have the time to look for industrial use or even
government use of electricity for lights, but it seems to be a good fraction
of total use.

Coming soon to a hardware store near you?  I certainly hope so.
