LEDs By The Dozen
Light emitting diodes. Solid state devices that provide the ubiquitous power and indicator lights on your electronic gadgetry. Unlike lamps, there are no filaments that glow. Rather, some two volts of DC power at a miniscule 10 to 20 milliamps of current get the chemistry excited, and they just plain emit. Emit is a good word, too, as they don't really cast light, but glow brightly. We have a nice assortment of 3 and 5 MM diameter sizes in red, green, orange, and yellow. The longer lead is always positive, the shorter always negative, and you always need a current limiting resistor (about 500 to 1,000 ohms for 5 to 9 volt DC sources) to keep the current in the 10-20 MA range. If that's Greek to you you're either going to blow a lot of LED's or learn to change incandescent indicator lamps ! !

Green LED
A nice green LED that is rated at 3 VDC 55 mA, but works at 4.5 VDC 120 mA. The first 1-1/4" of the leads are sheathed, and hold the LED upright. The remaining 8-1/2" of twisted leads end in a 2-pin connector.

Tiny Table Lamp
On tiny tables or the desktop, this lamp throws a nice puddle of light for its size. The 4-1/4" x 3" x 1-1/2" tall base supports an 8" long gooseneck with (14) bright white LEDs at the top. Silver-plastic and chrome, with a pushbutton switch on the base, it comes with (3) "AAA" batteries. We're putting ours on top of the dresser so maybe we'll finally be able to tell what color socks we're taking out of the top drawer, but it would make a nice little reading or camping lamp. Should give 15 hours of light with fresh batteries.

A Message From One Of Your Fans
Literally. Here's a little (4-3/8" tall) battery-operated plastic fan with an LED display built into one of the rubber blades. While it blows the air it also magically flashes (6) different messages of up to (16) characters each. You create the messages with push-buttons on the side and watch them scroll and rotate. "I'm all sweaty" and "Leave me alone" both fit, we've learned. Will hang from an 18" neck cord or stand up on its little bottom. Fan body color can be blue, red, green or black, our choice. The (3) "AA" batteries it needs are included.

Get A Little Flashy
Small glittery flashing LED buttons, each 7/8" dia round x 1/2" thick with a tiny on/off switch, a magnetic back and a steel disc to attach it to paper or fabric. Put a bunch on your shirt for your birthday, brighten up the logo on your cap, or highlight your name tag at the next convention. People ignoring your notes? Use one as a paper clip. They work nicely as hair ornaments but, sadly, the magnets are not quite strong enough for earlobes. Each comes with a replaceable (if you have tiny-enough fingers) CR927-G7 button cell inside. Our each is a box of (10). You'll get (3) light green, (3) red and (4) blue, but the LED flashers inside are all red and green. Even if you do get an occasional dud (which you might), these are a real bargain at this price!
