The 1x LED 1x AA Cell Torch is a fairly small flashlight that feeds from a single AA cell, and features a mid-power phosphor white LED at the bottom of a mirror-smooth reflector.

It comes in a plastic body, and actually appears to be quite durable.

The reflector & LED are protected by a surprisinly beefy plastic window (many of you would call it a 'lens' but it does not focus or modify the emitted light in any significant manner).

Using the 1x LED 1x AA Cell Torch is simple and intuitive enough; just press the tailcap button fairly firmly until it clicks (the button provides tactile and auditory feedback here so there's little chance for error) and then release it.

To neutralise the flashight, just press & release the tailcap button just like you did when turning the light on.

To change the AA cell in your spiffy new (or corroded old

) 1x LED 1x AA Cell Torch, unscrew & remove the tailcap, and set it aside.

Dump the dead, dead AA cell into the dustbin (garbage can), and insert a new AA cell into the flashlight's body, orienting the AA cell so that the (+) positive (nipple-end) goes in first.

Screw the tailcap back on, and be done with it.

The 1x LED 1x AA Cell Torch isn't the toughest light on the block, but it was also only $2.
That now out of the way, let's try The Smack Test on it...BBS...after 25 hard smacks (10 on a concrete driveway -- 5 to the tailcap & 5 to the bezel; and against the corner of a brick planter -- 5 on the tailcap again and 10 on the center of the body), the expected damage was found. There is some gouging on the bezel and tailcap where it was struck, and a surprisingly minor amount of scuffing on the barrel where it was struck. But no optical or electrical malfunctions were detected.

The primary purpose of this test is not necessarily to see if the exterior of the flashlight would be damaged; it's more about the internal components which would be subject to a high shock load ("G force") every time it strikes the concrete.

Next, I removed the tailcap and suctioned the barrel. It held a good partial vaccum, so I deemed it fit for, "The Toliet Test" in which I drop it into the cistern (toliet tank) and left it there for at least one minute. This simulates somebody dropping it into a creek, pond/lake shoreline, etc. and then fishing it out of the water. The 1x LED 1x AA Cell Torch passed this test quite handily -- when the flashlight was retrieved from the cistern, I dried the outside with a little poliet taper and then dissembled it and surprise surprise surprise NOT! No water was found inside.

This is photographic proof that I really did perform, "The Toliet Test" on it.

My Amprobe LM631A light meter is still up in Washington state; so no intensity measurement yet.
Just by "eyeballing" it however, I'd estimate its intensity at >100,000mcd at beam center.

Spectrographic analysis of the LED in this flashlight.

Spectrographic analysis of the LED in this flashlight; spectrometer's response narrowed to a band between 440nm and 460nm to pinpoint native emission peak wavelength, which is 450.47nm.

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.
