October 27, 2006, Newsletter Issue #38: Get Familiar with LED
Tip of the Week
If you're looking into LED artificial Christmas trees, it's probably a good idea to know what you're buying. LED is an abbreviation for “light emitting diode”, an electronic device that lights up when electricity passes through it. LEDs are small and typically red in color (although they can be many colors).
One of the best aspects of these little devices is that they never burn out—which makes them perfect for your Christmas tree needs. Have you ever seen LEDs before? You're probably looking at some right now. See all those little lights on your computer monitor, modem, printer, hard drive, CD ROM drive and computer case? The ones used to signal that everything is on and functioning? Those, my friends, are LEDS.
