Aitec AT3100L 'Sure Grip' Flashlight, retail $69.95 (www.quality-items...)
Manufactured by Aitec for Diamond Flashlights (
Last updated 11-11-04

The Aitec AT3100L 'Sure Grip' flashlight is a small, bright flashlight that comes in an aluminum body, and features a 3 watt Luxeon LED at the base of a smooth reflector to produce its beam. Three AAA cells in a side-by-side carriage inside the barrel power that LED, and an extremely aggressive texturising on the barrel help aid in retention - you won't drop this flashlight with cold, wet, oily, or gloved hands very readily at all!!!
I guess that's why they call it 'Sure Grip'.


This flashlight came to me ready to use, with batteries already installed. If yours does not come with the batteries installed, put them in (see directly below), and then you'll be ready to rock.

To turn the flashlight on, press the tailcap button until it clicks and then release it.
To turn the flashlight off, just do the exact same thing again.

There is no momentary or signalling mode available when the flashlight is off, but you can blink it while it's on by pressing the tailcap switch less firmly (before it clicks).

The flashlight comes with a nylon belt holster that has a hook and loop fastener on its flap. The flashlight will fit in the holster bezel-up or bezel-down - your choise here.
A belt loop on the back of the holster will fit belts up to ~2 inches wide; however since I do not own or use pants that require a belt, I cannot test this accessory in the manner in which it was intended.

This flashlight uses three AAA cells held in a carriage inside the barrel.

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

Tip the carriage out of the barrel. Remove the used AAA cells from the carriage if necessary, and dispose of, recharge (for rechargeable cells only!), or recycle them as you see fit.

Insert three new AAA cells in the carriage, orienting each cell so the flat-end (-) negative faces the spring for it in each chamber.

Slide the full carriage back in the flashlight barrel so the raised button goes in first (toward the flashlight head). Screw the tailcap back on, and be done with it.
Aren't you glad you didn't flush away that tailcap now?

Current consumption measures 636mA on my DMM's 4A scale and the Duracells that were included with it.

The first thing I noticed about this flashlight was just how aggressive (sharp) the texturising on the barrel was. There's just no way you could lose this flashlight by having it slip out of your hand. Ain't gonna happen, folks!!!
There's a reason they call it 'Sure Grip'. I kid you not. If you lose this flashlight by having it slip out of your hand, then your hands must be made out of teflon or something.
This texturising is EXTREMELY aggressive, and would probably eat through your pocket rather quickly if you carried the flashlight that way on a regular basis. Use the nylon holster that is included - that's what it's for.

Now let's get to what I'm known for...the beat test...after being beaten ten times against the edge of a concrete stair (five against the bezel and five against the tailcap), damage to the flashlight is very, very, very minor. Some slight scuffing on the side of the bezel where it was struck, and some small, minor denting on the side of the tailcap where it was struck. The flashlight has shown no evidence of optical or electrical malfunctions.

I tried to cut through to bare metal with the blade of a Swiss army knife, and with only minor difficulty, I was able to. This tells me that there is probably a Type II anodizing on this flashlight.
Would I really try to cut up a brand spanken new flashlight?
You bet your sweet patootie I would, if it's in the name of science.

This flashlight is water-resistant, and probably submersible to a short depth too. When I performed that dreadful suction test on it, no air was admitted. The tailcap also leaked no air, even when the switch was actuated several times. So you need not be concerned about using it in foul weather; and shallow water landings should not kill it either. If the dog lifts his leg on it, just take the garden hose to it or douche it off under the faucet...good as new!

The beam has a slight greenish tint to it, but if you showed the beam to a group of people and then asked them what color it was, I guarantee you that the vast majority of them would holler out "WHITE!!!" in answer to that query.
