OZARK TRAIL LED HEADLAMP
Ozark Trail Headlamp, retail $9.82* (www.wallart.com...)
Manufactured by (Unknown) for Wall*Mart (www.wallmart.com)
Last updated 08-06-20
The Ozark Trail Headlamp is part of a six-piece package that also includes an LED lantern, two LED penlights, and two 6x LED flashlights.
For this review, I'll only be focusing on the headlamp.
This headlamp uses an unusual high-power phosphor white LED with five dice (light-emitting regions) to produce a remarkably potent medium flood with a bit of an abrupt edge to the beam.
It gets its power from three AAA cells, which are included in the package.
Advertised runtime is 3 hours.
* This comes as a six-piece set, including this head lamp, two penlights, two flashlights, an LED lantern, and 17 AAA cells all for $9.82.

To use the headlamp, feed it first (see directly below) and THEN you'll be ready to go camping or brighten up that room after a power failure.
To turn the headlamp on in "high" mode, press & release the orange pushbutton on the upper part of the front of the product.
To turn the on in "low" mode, press & release the orange button again.
To turn the on in "strobe" mode, press & release the orange button again.
To neutralise the headlamp, press & release the orange button again.
Just like it reads on the backs of many shampoddy bottles, "lather, rinse, repeat". In other words, pressing & releasing the orange button again turns the headlamp on in "high" mode.
Photograph of me with the headlamp on.
I'd have normally used a, "Phoam Head Phred" (a styrofoam wig modelling form) for this shot, but I was forced to dispose of it prior to a move that I made in 2008.
My left eye is what's known as a, "googly eye" as a result of a serious brain operation that I had in 2002; please ignore it. And I look a bit piddled-off in this photo even though I'm really not; the same brain surgery that fv¢k€d up my left eye also robbed me of my ability to smile.
To change the AAA cells in this headlamp, press and hold in the two black buttons on either side of the product, and pull the two halves of the unit apart.
Set the black piece aside.
Remove the three the "dead-as-a-doorknob" AAA cells from the unit and dispose of them into the dustbin (garbage can) or drop them into the battery recycling box if your community has a battery reclamation program in place.
Install three new AAA cells into headlamp, orienting them so that their flat-ends (-) negatives face a spring for them in each compartment.
Finally, fit the two halves of the headlamp together and use your fingers to squeeze them until the little black buttons snap into place and protrude slightly out of the holes for them in the grey half of the case.
Current usage measures 172.60mA (high) and 48.0mA (low) on my DMM's 200mA scale.
Unable to measure strobe mode because it's...well...STROBE MODE.
The Ozark Trail Headlamp appears to be reasonably durable, but because of its all-plastic construction, will be spared The Smack Test.
I know that you like to see me and try to break stuff, but "ain't" "gonna" happen today, folks.
Water-resistance is negligible at best; you'll most likely be okay if you use this headlamp in ***LIGHT*** mist or sprinkles, but anything heavier than that will probably kill it.
The LED appears to be a COB (Chip On Board) type.

Measures 26,700mcd (high) and 9,770mcd (low) on an Amprobe LM631A light meter.
If I've told you once, I've told you 2,458,770 times: wider viewing angles always, always, ALWAYS produce lower mcd values!
Output is stated as being 30 lumens; however you need a rather expen$ive instrument called an integrating sphere to measure light in lumens, and I do not own or have access to one of these critters.

Spectrographic analysis of the white LED in this headlamp.
Spectrographic analysis of the white LED in this headlamp; spectrometer's response narrowed to a band between 440nm and 460nm to pinpoint native emission peak wavelength, which is 451.180nm.
The raw spectrometer data (tab-delimited that can be loaded into Excel) is at ot-head.txt
A beam cross-sectional analysis would normally appear here, but the ProMetric System
that I use for that test was destroyed by lightning in mid-July 2013.

TEST NOTES:
Test unit (the entire kit actually) was purchased from the proprietor of the Happy Market located at the intersection of N. Maple Ave. and W. Shields Ave. in Fresno CA. USA on 04-29-20.
He offered to sell it to me; of course since I've been running this website for over 20 years, I took the bate.
