Inova X03 Flashlight, retail $54.95 (
Manufactured by Inova (
Last updated 10-12-07

The Inova X03 is a fairly small, almost all-aluminum flashlight that has a 5.8 watt (advertised) Luxeon LED in its business-end, and uses two CR123A lithium camera cells to power that LED.

The body of the flashlight is black anodized aluminum, which is texturised to aid in grip.


Press down on the rubber tail button to turn the light on in momentary mode. Release to turn the X03 off.

Twist the tailcap (as if tightening) it to turn the X03 on in continuous (hands-free) mode. The light will then stay on without any further intervention on your part. Twist the tailcap counterclockwise (as if loosening it) approximately 1/8 of a turn to turn it off.

To engage the LOTC (Lock Out Tailcap) function, unscrew the tailcap approximately 1 turn more, and the light will not activate itself and waste the battery when packed away in a box, backpack, or camping bag.

To change the batteries in the X03, unscrew & remove the tailcap, throw it in the {vulgar term for feces}bowl, yank that silver handle on the front of the cistern down, and flush it away...O WAIT!!! YOU'LL NEED THAT!!! So just set it aside instead.

Tip the dead CR123A cells out of the barrel and dispose of or recycle them how you see fit. Lithiums don't like water, so don't throw the dead batteries in a full tub or try to flush them down the john.

Drop two new batteries in the barrel, button (+) end facing up. This is the opposite polarity of how the batteries are installed in most other flashlights, so please pay attention here. Screw the tailcap back on; and back it off slightly when the X03 springs to life.
There, you're done with it.
Aren't you glad you didn't flush that tailcap away now?

Current consumption measures 653mA on my DMM's 4A scale.

This is a loaner, and I'm sure its owner will want it back with no dings in the bezel or rat pellets or yukky old toliet water in the barrel. So I won't throw it against the wall, stomp on it, try to drown it in the {vulgar term for feces}bowl or the cistern, run over it, swing it against the concrete floor of a patio, bash it open to check it for candiosity, fire it from the cannonada (I guess I've been watching the TV program "Viva Piņata" too much again - candiosity is usually checked with a laser-type device on a platform with a large readout or with a handheld wand that Langston Licktoad uses), send it to the Daystrom Institute for additional analysis, or inflict upon it punishments that non-loaner flashlights may have inflicted upon them.
So this section of the flashlight's web page will seem a bit more bare than this section of the web page on a page about a flashlight that is not a loaner sample.

The Inova X03 is weatherproof and highly water-resistant at minimum. When that dreadful suction test (this is a totally nondestructive test!) was performed on it, no air leakage was detected.

The barrel has longitudinal flutes milled into it; this helps to aid in retention (the ability to hold the flashlight when your hands are cold, wet, or oily).

The light produced by the X03 is a pure white, with no yellow, blue, purple, or "rotten Weddel seal urine green" tint anywhere in it.

Test unit was loaned to me by a website fan on 10-10-07, and was received on the afternoon of10-11-07.

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