The LED-Lenser V Square (also known as the 7736) is a small handheld flashlight that uses a white Luxeon III LED and an acrylic optic to produce its light, feeds from three AAA cells held in a side-by-side carriage in its barrel, and comes in a black Type II anodized aluminum body.


This flashlight came to me already fed, so it ought to be ready to rock when you receive it too.

Press the button on the tailcap until it clicks and then release it to turn the flashlight on.
Press the button on the tailcap until it clicks and then release it to turn the flashlight off.
Yes, it really is as easy as that.

To use momentary or signalling mode, press the button less firmly (before it clicks) and hold it that way for as long as you need the light; releasing the button turns the V Square back off.

The V Square comes with a nylon belt holster; however, since I do not own or use pants that require a belt, I cannot test it in the way in which it was intended.
The flashlight fits in the holster bezel (head)-up OR bezel-down, and the holster has a Velcro flap that closes over the top, preventing the flashlight from unintentionally falling out

To change the batteries, unscrew and remove the tailcap, gently place it on the ground, and kick it in the garden so the praying mantids will think it's something to eat and strike at it...O WAIT!!! YOU'LL NEED THAT!!! So just set it aside instead.

Tip the black plastic battery carriage out of the barrel and into your hand. If necessary, remove and dispose of or recycle the used AAA cells from it.

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

Slide the now-full battery carriage into the flashlight barrel, orienting it so the spring on one end of the carriage goes in first. Finally, screw the tailcap firmly back on.
Aren't you glad you didn't kick that tailcap into the garden with all those praying mantids now?

Current usage measures 253.6mA onmy DMM's 400mA scale.

The flashlight appears to be reasonably sturdy. Ordinary flashlight accidents should not be enough to do it in. I administered the smack test on it (ten whacks against the corner of a concrete stair; five whacks against the side of the tailcap and five whacks against the side of the bezel), and found the expected damage. There is some gouging on the sides of the tailcap and bezel where it was struck. No optical or electrical malfunctions were detected.

This flashlight is splash- and weather-resistant at absolute minimum, but it is not submersible. So please try not to drop it in creeks, rivers, ponds, lakes, oceansides, docksides, puddles of white lab rat pee, slush piles, mud puddles, tubs, toilet bowls, cisterns, sinks, fishtanks, dog water dishes, or other places where water or water-like liquids might be found. A little rain or snow probably wouldn't hurt it though, so you need not be too concerned about using it in moderately bad weather.
Because I already determined it is not waterproof, I won't try to drown the V Square in the toilet.

If it fell in water and you suspect it got flooded, disassemble it as you would for a battery change, dump the water out of the barrel if necessary, and set the parts in a warm dry place for a day or so just to be sure it's completely dry inside before you reassemble and use it again.

If it fell into seawater or if somebody or something peed on it, douche all the parts out with fresh water before setting them out to dry. You don't want your flashlight to smell like seashells or urine when you go to use it next. Besides, salt (from seawater or pee) can't be very good for the insides.

The end of the flashlight where light comes from is not protected; there is also a hole visible there. So you should try to keep the V Square in its holster if possible to help prevent damage to this component and to help prevent lint and other nasties from getting in there.

The light color is a pure, slightly cool white, with no pink, yellow, blue, purple, or "rotten octopus urine green" tint to it. Not in the hotspot; not in the corona either.

The barrel has fairly aggressive (sharp) knurling (crosshatch-shaped texturising) on it, so retention (the ability to hold onto the flashlight when your hands are cold, oily, or wet (with water, milk, Orange Crush, ginger ale, Pepsi, wee-wee, beer, or coffee)) should not be an issue.

Test sample was sent by "Doc" of www.GlowGadgets.co.uk and was received in 12-23-05.

UPDATE: 09-18-06
I have been informed that a new, signifigantly brighter V Square flashlight is now available. It has been reported that the new version of the V Square is available at Target stores in the United States.

Bright for a one-banger
Sturdy metal body
Knurling is aggressive enough to greatly aid in retention

Not that water-resistant
Front end of flashlight is not protected
