The LED Earlight is a reading light designed to be placed on your ear to light up only the pages of the book you have your nose buried in and nothing more.

It comes in a plastic body with a flexible, curved rubber "stalk" to fit over your ear, has three modes plus off, and has a white LED in its "turret".

It feeds that LED with a pair of CR2032 lithium coin cells.

To use the LED Earlight, feed it first (see below), and then you can go to town.

Press and release the pushbutton switch once to get "fast blink" mode, press and release it again to get "slow blink" mode, press and release it again to get "steady-on" mode, and finally, press and release it a fourth time to turn the LED Earlight off.
Just like the back of the shampoopoo (or shampeepee) bottle reads, "lather, rinse, repeat".

There is a piece of grey rubber or rubber-like tubing that fits over the outside of your ear. The part of the light containing the LED and the switch can be swivelled up or down over an approximately 65 degree angle; this turret also pivots inward and outward over a 10 to 15 degree range of motion. I do not have the equipment to measure these angles though, so I kinda had to "eyeball" them.

The LED Earlight is labelled to fit over either ear. It appears to be tailored specifically to fit over your left ear though, as the grey rubbery tubing that fits on the outside of your ear will go over the top.
It does fit over the right ear, but it feels a LITTLE less secure than it does over the left ear because it fits over your right ear with the end of the grey rubber tubing over the top & front of your ear rather than behind it - it seems to fit the right ear "upside-down" as the photograph directly below shows.

Product shown fitted to my right ear.
I'd have normally used a "Phoam Head Phred" (styrofoam wig modelling form) for this photograph, but my parents forced me to throw it in the garbage can in December 2008 prior to us moving from Sacramento CA. USA to Federal Way WA. USA around New Years Day 2009.

To change the batteries, turn the LED Earlight so the turret (the part with the switch and LED) is on the bottom. You'll now see a circular battery door with some projections on it. Turn this door approximately 1/8 to 1/4 of a turn counterclockwise (as if loosening it), note how the projections on the battery door are oriented with regards to the rest of the LED Earlight, lift it straight off, throw it in the john, and flush it away...O WAIT!!! YOU'LL NEED THAT!!! So just set it aside instead.

If necessary, remove the two expired CR2032 cells from the battery compartment, and dispose of or recycle them as you see fit.

Insert two new CR2032 cells, orienting them so the flat side (+) positive faces up.

Place the battery door back on, rotating it so the projections on it are oriented the way they were when you first removed the door, and turn it 1/8 to 1/4 of a turn clockwise (as if tightening it). Just turn until it stops - it is now on and should not fall off of its own accord.
Aren't you glad you didn't flush away that battery door now?

Due to the way the LED Earlight was constructed, I cannot take current consumption readings.

The LED Earlight is reasonably durable - at least to the point where it won't just fall apart or go out during normal use. This product is intended specifically to be used on your ear, not abused or manhandled like a regular flashlight. So I won't try to slam it against a steel rod or flush it down the can. I did throw it to the floor a few times, and did not damage it in any way I can detect.

Measures 14,630mcd on a Meterman LM631 (now Amprobe LM631A) light meter.

Unit lighting up the pages of a book about used-up old insulaters.
As you can see, the beam is a bit too narrow for this product to do a truly excellent job here. It's not *BAD* by any means; it's just not superb.

A beam cross-sectional analysis of this type of product should not even be necessary, but the beam is narrow enough here to warrant such a test.

A product's country of origin really does matter to some people, which is why I published it on this web page.
