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 ! !

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.

Poor Man's Luminaria
It's a little 2-1/2" square base with brushed-aluminum-look sides and a mirrored top, in the middle of which 3 colored LEDs flash on and off in individual and combination patterns. Makes a dandy base to show off crystal and cocktail glasses, but stick a large styrene coffee cup upside down over it and put it in a dark room and you have the world's cheapest multi-color light show. Line up a dozen or so on the front walk and you've got the world's first flashing multicolored luminaria show for party nights. You add (3) "AAA" batteries.

Mighty Bright Loupe
This 8X folding loupe in white plastic and aluminum has a pair of very bright white LEDs next to the lens. Runs on (3) button-cell batteries, included, and has a tiny wrench to help you replace them. When folded, it looks like a standard coach's whistle, or a really big apostrophe. Forgive the package for saying 30X - if it didn't say it, we wouldn't have it!
