What's about the size of a piece of candy, and just as colorful and cheerful looking?
Why, Gemlites, of course.

Gemlites are tiny (0.33 ounces), bright LED keychain lights that come in an assortment of bright, playful colors. They feature a super bright LED and are powered by common lithium coin cells. A spring-loaded keychain attachment keeps Gemlites handy on your keychain, ready to use at a moment's notice.


Gemlites are ready to use right out of the pack. Use a sharp knife or scissors to slit the side of the pack open, and you can then remove the goody inside without wrecking the card. Each one has a momentary switch: give the light a squeeze to turn it on, and stop squeezing to turn it off.

A spring-loaded clasp allows you to affix the Gemlite onto your keyring, zipper pull, or other suitable place; and a swivel collar prevents anything from becoming twisted or tangled no matter what else is sharing your keyring with the Gemlite.

Batteries are a "warranty item" much like with the Asp Sapphire; and aren't supposed to be user-replaceable. When the batteries expire, pack up your Gemlite along with your return address and $2 and mail it to:

Gemlite Division
International Parallel Machines
50 Conduit St.
New Bedford, MA. 02745-6016

Expected total battery life is approximately 10 hours; which is in line with other lights using this type and style of battery.

Gemlites are nice looking, and seem to be made from a slightly resilient plastic, rather than the really brittle material that some inexpensive lights are made from.

Colorful, like Christmas candy

Therefore, dropping them probably isn't going to damage them; though under some conditions, a small dent may be found. Test drops so far have not resulted in breakage; only a clattering, plasticky kind of sound as they smack into the floor. But wait till I load up my heavy keyring with a couple of Gemlites and repeat the test - then we'll see what happens.

Gemlites come in 5 colors; the LED color corresponds with the case color. The colors are associated with gemstones (hence, Gemlites, get it?) and are as follows:

Red - Ruby
Yellow - Topaz
Green - Emerald
Blue - Sapphire
White - Diamond

These flashlights are about as cute and loveable as they come - all they need is a smiley face on them and you have the makings of a new cartoon! Kids will love having these hanging from their keychains and book bags - assuming of course the school district in your area hasn't added "keychain flashlights" to their list of banned articles. :-P

30,000mcd White

IMPORTANT: These are peak instantaneous readings - in actual usage, the light output will drop substantially within the first several minutes. This is true of ALL direct-drive keychain flashlights using this type and style of battery, and does not in any way indicate a problem with the Gemlite.

I did not perform spectroscopy (pronounced "") of the red because I don't know where it is at the moment.
