If you're looking for a tiny LED flashlight, look no farther than the Micro Opto E-Light. This tiny thing is powered by an equally tiny lithium battery, and provides a red-orange light for up to 20 hours on the same battery.

The all-metal flashlight is smaller than a common cigarette, and probably better for your health too.


The light comes ready to use right out of the package.

Turn the knurled tailcap clockwise to get light; turn it counterclockwise to turn it off.
Flashlights just don't get much easier than this.

What the heck is that thing?!?!
If you can believe it, this is the battery used by the Micro Opto E-Light. Eddie Bauer sells stuff used by outdoors type people, but I dare you to find this battery at the local 7-11 on your way to the campsite. It is a lithium BR435 cell, used in some types of lighted fishing lures.

If you can find a replacement, changing the battery is as easy as unscrewing the tailpiece, dumping, and then dropping the new battery in the barrel with the pin portion going in first. Then screw the tailpiece back on; and back it off a bit when the flashlight comes on. I've been told the battery this light feeds from is used in some types of electric fishing lures, and as such you just might find them in your local bait shop or wherever lots of fishing supplies are sold.

Stated life is 20 hours. We'll see about that.

The first thing you'll want to do with this thing is put it on your keys, or else you will probably lose it. It's small enough to go down the drain.

Speaking of drains, the light is not 100% watertight, so try to keep it out of sinks, tubs, and toilets. It is weather resistant and sprinkle resistant though, so it should do fine if it gets rain or snow on it while you're using or carrying it. But will leak through the head, so please don't drop it in the toilet or the fishtank.

Light was received in March 2002. I apologise for not having the review done more quickly.

UPDATE: 10-29-03
I have heard from a reliable source that more recent LED-Lenser products really do have lenses on the end, rather than just the bare LED. This product is apparently one of them. While the model I have for testing does not have a lens, apparently a more recently produced model does.

UPDATE: 12-27-04
I have heard that this flashlight may also be sold as the Nano-Lenser.

Small and easy to hide
Very good looking for a flashlight

Not waterproof
Strange battery might be expensive and/or difficult to find
Dimmer than most other LED flashlights
