LEDBeam 3xC 3W Luxeon Flashlight, retail $39.95 (www.ledbeam.com...)

Last updated 03-05-07

This is an almost all-aluminum flashlight that uses a Luxeon III LED at the bottom of a mirror-smooth reflector, and is powered by three C cells in its barrel.


The flashlight comes almost ready to use right out of the package; just needing to be fed three C cells that you provide.

Press the rubberised button on the barrel until it clicks and then release your finger and the flashlight will come on. Press and release it 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 the light while it is already on by partially depressing the button. If you don't mind the reverse or "backward" feel, you can blink the light this way.

To change the batteries, unscrew and remove the tailcap, throw it in the garbage can (dustbin), and take the garbage bag (bin liner) to the outside garbage so the garbage man (dust man) will haul it away in his garbage truck (dust lorry) next week or a few days or whenever garbage day is for you...O WAIT!!! YOU'LL NEED THAT!!! So just set it aside instead.

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 into the barrel, orienting them so their button-ends (positive) (+) go in first. Don't just drop the batteries straight down or you might cause damage; hold the flashlight so its barrel is nearly horizontal (so the head is only slightly lower than the tail), and then load it by pushing the C cells in so they slide gently down.

Screw the tailcap firmly back on.
Aren't you glad you didn't dispose of that tailcap now?

Current consumption measures 1,201mA on the DMM's 4A scale.

This is a very nice looking flashlight; with two bands of knurling (cross-hatch shaped texturising) (one wide band on its barrel; one narrow band on its tailcap). Because of this knurling, retention (the ability to hold onto the product when your hands are cold, oily, or soaked with water, diet Pepsi, milk, or pee) should not present a problem.

I beat the living tweedle out of it (ten whacks against a concrete patio floor; 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 minor gouging to the bare Metaletemon - er - the bare Metalgarurumon - um no that's not it either...the bare Metalkabuterimon...er...uh...wait a sec here...THE BARE METAL (guess I've been watching too much Digimon again! ) on the sides of the tailcap and bezel where it was struck. No optical or electrical malfunctions were detected. It still produces the same predominantly circular medium spot that it did when I removed it from its package for the first time.

This flashlight appears to be at least somewhat weather-resistant (there are O-rings on the tailcap and on the bezel), but water resistance is not superior. When I relieved the flashlight of its batteries and then suctioned it, a fair amount of air was admitted. So it should be OK to use it in lightly bad weather, but try not to dredge it. If it falls into water or you otherwise suspect it got flooded, take it apart as you would for a battery change and let the pieces dry for a day or so before you reassemble and use it again.

If it fell into seawater or if somebody or something peed on it, douche all the parts with fresh water from the faucet before you reassemble & use it again; you don't want your flashlight to smell like a "flushlight" now, do you?
Besides, salt (from seawater or urination) can't be very good for the insides.
