NUWAI HLX-813A
LUXEON HEADLAMP

Nuwai HLX-1113A Luxeon Headlamp, retail $21.50 (www.amondotech.com...)
Manufactured by Nuwai (www.nuwai.com)
Last updated 08-28-05




The Nuwai HLX-813A 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, and feeds from three 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.


SIZE



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.


Photograph of the headlamp on a flashlight tester's head.
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.



Unfold the headlamp away from the strap assembly. As the headlamp is facing forward, turn the black oblong cap on the left side of the body counterclockwise (as if unscrewing it) approximately 1/8th of a turn, pull it straight off, 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 according to the polarity labels in the bottom of each chamber - do not let the leaf springs in the chambers be your guide - that won't work here.

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 illuminator head. Slide the battery carriage in - do not force it. Place the black cap back on, and turn it clockwise (as though tightening it) approximately 1/8th of a turn, 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.



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, and possibly even submersible to shallow depths too. When I removed the battery cap, relieved the headlamp of its battery carriage, and administered that dreadful suction test, it held a vaccume (vacumn, vacume, vaccuummnne, vaccuumne, vaccum, vacuum, etc.). So it should easily withstand being used in crappy weather without leaking or becoming flooded, and shallow-water landings shouldn't kill it either. The dog just took a leak on it? No problem. Just take the garden hose to it - good as new.

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 porpoise urine" green tint to it. Not in the hotspot, not in the corona either.

Like the other Nuwai headlamp I evaluated today (08-28-05), the hotspot is slightly irregular in shape, but not so much that it would detract from the usefulness of this product.

Look a lot like that other Nuwai headlamp's web page?
No, you're not seeing things.
I used it as a template for this web page.

TEST NOTES:
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.
