Last updated 08-28-05

The Nuwai HLX-1113A Headlamp is a head-mounted light that uses a 1.2 watt SE (side-emitting) Luxeon Star LED to produce its light, has four modes (high, medium, low, and blink) accessible from a single pushbutton, feeds from three AAA cells, and has one thing found in very few flashlights or headlamps: an LED battery status indicator.

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 Nuwai HLX-1113A headlamp (hereinafter, just called a headlamp), feed it first (see directly below), and then you can go paint the town red - or in this case, white.

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 right side of the battery chamber once for high mode. Press and release it again for medium. Press and release it a third time for low. Finally, press and release it a fourth time to turn the unit off.

From any mode (including off), pressing and holding in the button for 3 seconds or more activates flash mode. This causes the LED to blink at full power at approximately 2Hz (2 blinks per second).
Regardless of which mode you were in when you activated flash mode, pressing and releasing the button in this state turns the unit off.

Unfold the headlamp away from the strap assembly. As the headlamp is facing forward, unscrew and remove the black cap from the left side of the yellow body, and set it aside.

Tip the battery carriage into your hand. If necessary, remove and dispose of or recycle the three used AAA cells from the carriage.

Insert three new AAA cells into the carriage, one in each compartment. Orient each cell so the flat-end (-) negative faces a spring for it in its compartment.

Once the carriage is full, insert it into the headlamp's body, orienting it so the label on one end faces outward, and turning it so the red arrow on the label is pointed toward the two ridges on one side of the inside of the body. Slide the battery carriage in - do not force it. Screw the black cap back on, and be done with it.

Finally, fold the headlamp assembly and strap assembly back to where you had it before, and there, you're finished.

Notice I did not advise you to stomp on anything or flush anything away.

Due to the way the headlamp is constructed, I am not able to provide you with current usage readings.

Battery life is advertised to be 1 hour on high, 3 hours on medium, 5 hours 30 minutes on low, and 2 hours 30 minutes on flashing mode.

It is stated on the package in capital letters to use alkaline cells only; apparently rechargeables do not have the testicles to operate this headlamp properly (insufficient terminal voltage), and lithiums might be just a bit too much for the poor thing.

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

It appears to be water-resistant, but NOT submersible. When I removed the battery cap, relieved the headlamp of its battery carriage, and administered that dreadful suction test, it leaked, but only VERY slowly. So it should easily withstand being used in crappy weather without leaking or becoming flooded, and shallow-water landings shouldn't kill it either if you fish it out right away. The dog just took a leak on it? No problem. Just take the garden hose to it - good as new.

One thing present on this headlamp that is uncommon to find on other headlamps or flashlights is a battery status indicator.
Approximately three seconds after turning the unit on, one of the battery status indicator LEDs just in front of the switch will light.
A green LED means you have plenty of power (100% to 50%), a yellow LED means "caution" (the batteries are pooping out; 50% to 20%), and a red LED means you should change the batteries as soon as possible (20% or less power remaining).

The brightness levels are labelled as 100%, 50%, and 25%.

The light output by this headlamp is a pure white in color, with no pink, yellow, blue, purple, or "rotten seal urine" green tint to it. Not in the hotspot, not in the corona either.

The hotspot is slightly irregular in shape, but not so much that it would detract from the usefulness of this product.

Test unit of this headlamp and 17 other products were sent by A.L. of Amondotech and were received late in the morning of 07-11-05.

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