LEDs

I had never really thought much about LEDs, until a friend showed me the GlowBug.com website. The GlowBug site is entirely devoted to LED lights of all kinds... flashlights, keychains, lamps, lanterns, headlights, and even booklights.

I learned a lot from GlowBug. Did you know that the life expectancy of an LED is 5 to 10 years of continuous use? Or that they consume less than 1/10 the electricity of equivalent lightbulbs? LEDs are also much less fragile than lightbulbs. (They don't break when you drop your flashlight!)

While still too expensive to replace household lightbulbs, LEDs are very affordable for flashlights and other "portable" applications. Plus... they're cool! (Literally, because unlike lightbulbs, LEDs waste very little energy in the form of heat.)
