The Elektrolumens XM-2 flashlight is an almost all-metal flashlight that has a type II anodized matte black finish, uses a 3 watt Luxeon Star LED, and a pair of CR123A lithium cells to power that LED.

It uses a custom-made optic, measuring 24mm diameter, and 12mm long, and produces a fairly wide hotspot with an even wider corona.


I believe you'll need to feed your XM-2 first, so go ahead and do that now (see below).

Once it's all fat and sassy, press and hold in the tailcap button to get momentary light, and release it to turn the XM-2 back off.

Twist the tailcap clockwise (as if tightening it) to get continuous, hands-free light. Twist the tailcap counterclockwise (as if loosening it) to turn the light off. This is continuous mode.

There is no LOTC (Lock Out TailCap) function in this flashlight; please do not expect to find one.

To feed your XM-2, unscrew and remove the tailcap, throw it in the toilet, and yank that silver handle down...O WAIT, YOU'LL NEED THAT TAILCAP!!! So just set it aside instead. ;-)

Tip the open end of the barrel in your hand, and dispose of or recycle the two used CR123A cells that come out as you see fit.

Insert two new CR123A cells into the barrel, button-end (+) positive first. Screw the tailcap back on; and unscrew it slightly when your XM-2 springs to life. Aren't you glad you didn't flush that tailcap away now? ;-)

Measures 1.10 amps (1,100mA). Measured on my DMM's 20A scale, to help minimise shunt resistance error.

As of the morning of 06-06-04, I'm running the XM-2 through my battery discharge analysis machine. This machine should poop out a chart later today.

And here's the chart the machine pooped out.
Runs for about 22 minutes to 50% intensity, and 2 hours 30 minutes overall.
When the test was ended, the XM-2 was approximately as bright as one properly driven 5mm LED.

The XM-2 is water-resistant, but not waterproof. You should be able to use it in the rain or snow and not have to worry about it, but dropping the flashlight into water or water-like liquids is not advised. When the tailcap was removed, the flashlight was relieved of its batteries, and then suctioned, it held a vaccume. But when the tailcap was replaced and the bezel end was suctioned, air got in. So it can leak through the tailcap, but not through the bezel.

The XM-2 is durable, in that it withstood 10 whacks against a steel rod (five on the barrel, five on the bezel) and it did not break or become damaged in any fashion. Very few flashlights are damaged or destroyed by this test, so maybe I should come up with something else.
Nothing like breaking flashlights, ya know. ;-)
It also withstood three drops to the floor; two moderate throws and a "lay up" against one of my wheelchair tires.

Speaking of wheelchairs, let's run over it and see what happens...BRB...ok, I ran over it four times with the left rear drive wheel of a 400lb electric wheelchair, and did not damage it. The XM-2 turned on when the tire was over it, and turned off when the tire had passed it. It did the same thing when I ran over it again. I soon found that I could activate and deactivate the XM-2 by pressing sideways on the tailcap. This only works if the XM-2's tailcap is unscrewed approximately 1/4 of a turn or less from constant-on.

The XM-2 comes with a nylon belt holster, however since I do not use or own pants that require a belt, I cannot test this accessory in the manner in which it was intended. The XM-2 fits in this holster bezel-up, and a velcro flap covers the bezel. The bottom of the holster is open, so the XM-2 cannot accidentally switch on.
The holster has both a closed loop and a velcro flap, so you can put the holster on when you put your belt on (using the closed loop), or put the holster on without having to take your belt off first (using the velcro closure).

The beam of light that comes out of the XM-2 is white, but has an overall slightly greenish or cyan tint to it. It is not objectionable though, and if you showed somebody the beam and asked them what color it was, they would most certainly holler out "WHITE!".

After about 30 minutes of constant-on, the head measures a temperature of 155F (68.3C)and the barrel 151F (66.1C).
While this is hot, it's not burning hot. So you won't burn yourself on the XM-2 if that's what you're worried about.
After about 70 minutes, the temperature of the head measures 131F (55C) and the barrel 129F (53.9C). So the temperature is going down.
