Last updated 11-08-05

This headlamp is a head-mounted light that uses a 0.5 watt high power LED to produce its light, has two modes (low & high) accessible from a single pushbutton, and feeds from two AAA cells.

It has an elastic (stretchy) 3-point headband system, so it feels comfortable to use even though the batteries and illuminator are both in the front.


To use the headlamp, place the headlamp - where else - on your head, and adjust the buckles so the unit fits properly.

The illuminator head is adjustable by swinging it down or up as needed; it is on a detent-equipped hinge with a fairly stiff action, so the headlamp should stay where you put it unless you hit it against something. The forehead plate has a foam rubber pad which rests against the forehead for comfort. The straps themselves are affixed to plastic loops with their centers open; this allows the straps to be removed for cleaning when necessary.

Press and release the rubberised button on the top of the unit once for low mode. Press and release it again for high. Finally, press and release it a third time to turn the unit off.
Just like it reads on the back of many shampoopoo (or shampeepee) bottles, "lather, rinse, repeat". In other words, pressing and releasing the button a fourth time turns the headlamp on in low mode.

The focus is adjustable from a medium spot to a narrow flood; to accomplish this, turn the bezel (the round part where the light comes out) counterclockwise to widen the beam, and clockwise to narrow the beam.
I don't think this headlamp was INTENDED to have an adjustable beam, but it does.

So why aren't my eyes showing in this photograph?
Because I had brain surgery in late-2002, and my left eye is now what's known as a "googly eye", and makes photographs look just terrible. So with every headlamp I've evaluated since early-2003, I have to crop the photograph above my eyes because it just looks wierd otherwise.

To change the batteries, turn the headlamp so the front (where the light comes out) is directed (aimed) forward.

On the left side of the unit behind the bezel (that circular part where the light is emitted), grasp the black cap, press in on it, and turn it approximately 1/12th of a turn counterclockwise (as if unscrewing it). It should now lift away, but remain attached to the body of the headlamp via a thin rubberised cord.

Tip the used AAA cells out of the body and into your hand, and dispose of or recycle them as you see fit.

Insert two new AAA cells in the body, orienting them so the cell on the left (toward the bottom of the unit) goes in button-end (+) positive first, and the other cell goes in flat-end (-) negative first.

Place the cap back on, press down until it fits flush (rotate it if necessary), and turn it approximately 1/12th of a turn clockwise (as if screwing it in) until it does not turn any more.

Notice I didn't suggest kicking, stomping on, throwing away, or flushing away anything here...there are no parts that come off to do that to.

Current usage measures 23.7mA (low) and 138.2mA (high).

The headlamp appears reasonably durable. Due to its plastic construction, I will not administer the smack test on it.

I administered that terrible suction test on this headlamp, and did not detect any leakage.
So it should be fine to use in foul weather, and shallow-water landings should not kill it either.

The light output by this headlamp is a white in color with a noticeable bluish tint. This tint isn't horrible and obnoxious in my opinion, but it is there and is noticeable.

Beam photo (narrow focus) at ~12".
Measures 112,000mcd (low), and 320,000mcd (high).

Beam photo (wide focus) at ~12".
Measures 14,200mcd (low), and 63,400mcd (high).

Beam photo (high, narrow focus) at ~15'.
That red star thing is from an American DJ Laser Widow, and that rectangular graphic thing at the lower-left is a marquee from a Williams 'Stargate' upright coin-op video game from the early-1980s.

All measurements were taken on a Meterman LM631 light meter.

Test unit was sent by an as-of-yet unknown outfit in Hong Kong and was received on the afternoon of 11-07-05.
