JEWEL LITE

Last updated 08-22-06




The Jewel Lite is a very nice appearing, somewhat effeminate looking LED flashlight. It is about the size of a large cigerette lighter, and should fit nicely in purses, handbags, and similar articles.

The Jewel Lite features a 10mm white LED, which is powered by a pair of lithium coin cells in a custom battery carriage. I believe the batteries and carriage are one piece, so you have to go where you purchased the flashlight (I bought mine on ebay at this link) to get another battery assembly for it, at a cost of $2.00.

There are holographic stickers on the front and back of the Jewel Lite, giving some measure of sophistication about it.


SIZE



The Jewel Lite comes ready to use right away. Slide the black slide switch on the side of the product down to get light, and slide this switch up to not get light.

There is no momentary or signalling function; so please do not expect to find one.



The battery carriage appears to be a complete assembly inside the flashlight, so you'll be replacing it in one piece.

Open the Jewel Lite by unsnapping the latch you find on its side, and swing the two halves open. Remove the old battery carriage assembly (a white, rectangular object), and dispose of or recycle it as you see fit. Insert a new battery carriage assembly, orienting it so the (+) sign marked on it is nearest the contact at the front edge of the flashlight - not near the hinge. See photograph immediately below to see the correct orientation of the battery pack. Close the Jewel Lite back up, and latch the latch so it stays closed.

Measures 44mA on my DMM's 2A scale.




The above photograph is of the Jewel Lite open, showing the 10mm LED and the battery pack.

The Jewel Lite is reasonably sturdy, but could become broken if stepped on, run over, or maybe even sat on, assuming the chair or couch you set it on is heavily upholstered. Normal and ordinary usage should not cause it to become broken. So you can keep it in a purse or handbag, and it ought to work when you need it to. Just don't stomp on it or violently sit your toilet muscle on it.

The light is not water resistant or submersible, so you should try not to drop it into creeks, rivers, ponds, lakes, puddles of dingo pee, snowbanks, oceansides, docks, mud puddles, etc.
If it fell into water or if you suspect it got douched, unlatch the side, remove the battery carriage, and dry the parts in some place warm and dry for a day or two, and the flashlight ought to be good as new again. If it fell into seawater or if something peed on it, rinse the parts in fresh water before setting them out to dry.

More later...let me just FTP this page up for now.

Exposure value reduced to -2.0 on my digital camera to show the beam better.
