FLT-4001-1LW Luxeon LED FlashLEDŽ Flashlight, retail $59.95 (www.ledtronics.com...)

Last updated 09-04-04

This is the newest incarnation of the FlashLEDŽ, made and sold by LEDTronics. It comes in an almost all-aluminum body, has a 1.2 watt Luxeon LED to produce its light, and uses three C cells in the barrel to power that LED.

The FLT4001 has an adjustable (focusable) beam, which you can set to spot or semi-flood just by turning the bezel (head).

It has a HD (high-dome or lambertian) Luxeon Star LED in it. I verified this by unscrewing and removing the bezel and examining the LED.


The FlashLEDŽ came to me ready to use, with three C cells already installed.

To use the FlashLEDŽ, press the rubberised button on the barrel until it clicks, then release it. This turns the flashlight on.
Press and release the button the same way again to turn the flashlight off.

There is no momentary or signalling mode available when the flashlight is off, however you can blink it while it's on by more lightly pressing the switch - before it clicks.

The bezel comes all the way off, so you can use the FlashLEDŽ like a candle, by standing it up on its tailcap. What little water-resistance there is will be lost if you do this though, so don't use it in the rain or snow like this.

The FlashLEDŽ comes with a nylon belt holster. The flashlight fits in this holster bezel-up, and a Velcro flap closure prevents loss of the flashlight when carried this way.
The holster has a Velcro closure for the belt loop; it appears to be designed to be used on belts up to two inches wide. 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.

The FlashLEDŽ operates on three C cells. These were included with the sample I'm evaluating for you today.

To change them, unscrew the tailcap until it comes off, and set it aside.

Tip the three used C cells out of the barrel and into your hand, and dispose of or recycle them as you see fit.

Insert three new C cells in the barrel, button-end (+) positive first. Screw the tailcap back on, and be done with it.

Current usage measures 665mA on the three alkaline C cells that were included with it.
Reading was taken on my DMM's 2A scale.

The FlashLEDŽ appears to be at very minimum reasonably durable. One of the first tests I did after measuring the light output was the smack test. I smacked it against a steel rod ten times (five on the tailcap, and five on the bezel), and caused very little physical damage to the flashlight (some very, very minor denting was found on the bezel), and the electrical & optical functionality of the FlashLEDŽ was not changed in the least.

I was able to scratch through the finish of the FlashLEDŽ with the blade of a Swiss army knife; showing that the finish is a type II anodizing.
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.
The body is made from CNC machined aluminum, so even if the finish does become scratched, the rest of the flashlight will not become damaged.

The FlashLEDŽ is weather-resistant, but it is not waterproof or submersible. When I removed the tailcap, relieved the flashlight of its batteries, and performed that dreadful suction test, leakage was found. So while you shouldn't have any problems in rain or snow, please try to keep it away from streams, rivers, ponds, lakes, oceansides, puddles of tiger pee, snowbanks, slush piles, pet water dishes, tubs, toilets, sinks, and other places where water or water-like liquids might be found.

If you know or suspect it got flooded, take it apart as you might for a battery change, and set the parts in a warm, dry place for a day or so. If it fell into seawater or if someone or something peed on it, douche the parts out with fresh water before setting them out to dry. You don't want your FlashLEDŽ to smell like seaweed or urine the next time you go to use it. Besides, salt (from seawater or potty) can't be very good for the inside.

The barrel has a grippy, rubbery material covering the majority of it. This material isn't just for looks, it helps to aid in retention (the ability to hold the flashlight with cold, oily, or wet hands) too. Do not attempt to cut this material off - you'll most likely be sorry if you do.
