The LEDSupply Mini Keychain Lanterns are very inexpensive LED flashlights that use a Nichia white LED and three LR44 button cells. They are currently being offered on Ebay by LEDSupply, and can be had very inexpensively.

From what I can determine, this flashlight uses a Nichia NSPW500 LED; rank and stopper presence not known.

A short length of chain and a split ring attachment are affixed to the tail-end of this flashlight, allowing you to hang it from a keyring or hang keys from its own split ring.


The keychain lantern is ready to go right away. No funny business here. ;-)

To get a shot of light whenever you need it, press and hold down the button on the flashlight body, just behind the bezel (head). Release the button to turn the lantern back off.

The keychain lantern can be affixed to your keyring or just stuffed in a pocket.

To change the batteries in the mini LED keychain lantern, unscrew & remove the black bezel assembly, and throw it away...O WAIT, YOU'LL NEED THAT! So just set it aside instead. ;-)
Remove the LED and reflector assembly, and set that aside too.

Tip the barrel of the flashlight into your hand, and dispose of or recycle the three LR44 cells that come out. Insert three new LR44 cells in the flashlight barrel, flat (+) positive side first.

Once all three cells are in right, pick up the reflector/LED assembly, and examine it for one of the LED leads curved up going up toward the reflector. You'll want to line this up so it touches the metal switch contact inside the flashlight when you screw the bezel back on. Lay the reflector/LED assembly in the barrel of the flashlight so the upturned LED lead touches the switch contact, and screw the black bezel and window assembly back on. The thin plastic window can fall out of the black bezel ring and get away from you if you aren't paying attention, so watch for that when you're changing the batteries.

If the flashlight does not work after a battery change, remove the black bezel ring and reflector assembly, and reinstall them. Lather, rinse, repeat as necessary.

This does not appear to be a very sturdy or durable flashlight, but I believe the price is right. Can't go wrong there. You need not be ashamed to admit you own or use one, or display one dangling from a keychain. They're very cute little things, so they've got that going in their favour too.

The flashlight does not appear to be very water resistant. There are no O-rings that I can see, so I'd keep this one out of lakes, streams, rivers, oceansides, snowbanks, puddles of rhino pee, sinks, tubs, toilets, fishtanks, or anywhere else water may be found. If your light becomes flooded, take it apart, allow the pieces to dry (douche them out with fresh water first if it fell in seawater or if something peed on it), and it ought to be none the worse for wear. It should be very lightly splash resistant though, so if somebody throws a drink at you and some of it gets on your light, just shake it off and keep going. Be sure you leave the bar; there's probably a darn good tootin' reason why somebody threw a drink at you.

Lantern is in its earliest stages of testing. I just want to get this page uploaded for the time being, and call it a night.

Beam photo at ~12".
Measures 15,100mcd with a Meterman LM631 light meter.

While this is decent for a 1-LED flashlight, the tiny button cells inside will
not be able to maintain that level of LED intensity on a continuing basis.

Samples of the LEDSupply Mini Keychain Lantern were sent by J.L. of LEDSupply and received on approximately 03-10-04; and as of 03-13-04 are in the initial stages of testing.
