The MT-023 is a combination LED flashlight and cellular telephone charger. You never have to buy disposable batteries for it, or be tethered to a recharging cradle, because the MT-023 has a dynamo built in that charges the unit's built-in rechargeable batteries.

The unit has five 5mm white Nichia brand LEDs, each positioned behind a positive (magnifying) lens in the bezel.

When the batteries poop out, you don't need to go and buy new ones - you unfold the hand crank and crank the dynamo with a winding motion. Clockwise or counterclockwise - doesn't matter here.


SIZE



The MT-023 comes ready to use right away, but as with all rechargeable products, it's probably a good idea to charge it first. So go ahead and do that now (see directly below), and then you can go paint the town red - or in this case - white.

Press the rubbery button on the top of the MT-023's body and then release it to turn the LEDs on; do the same thing again to turn the LEDs off. This is continuous or hands-free mode.

Press the button less firmly and hold it that way for as long as you need light; release the button to turn your MT-023 off. This is momentary or signalling mode.

To charge a cellular tephone, find the included cord, and grasp the male 1/8" stereo phone plug in one hand. On the left side of the MT-023's body, there is a rubber cover over the cellular telephone charger jack. Lift the tab on this cover (gently, so you don't just rip it right out of the flashlight body) to expose the female 1/8" charger jack. Plug the plug into the jack.
Plug the other end of this cord (looks like a 1/8" female DC plug) into the DC In jack on your telephone. The telephone should immediately start charging. Crank the flashlight dynamo's handle clockwise or counterclockwise at ~130RPM. According to the instructional material, one minute of charging provides two minutes of "talk time".

Normally, there is no need to change the batteries, but they are user-replaceable if need be in the future.

Unfold the crank, and turn it clockwise or counterclockwise at ~130RPM (just over two rotations per second). A green LED between the crank and the bezel comes on when you're turning the crank correctly, and goes out approximately two seconds after you stop cranking.

As taken from the web page the MT-023 is on:

It takes about 1 hour of cranking to completely recharge the battery, which will run the LEDs for about 24 hours. 1 minute of cranking on an empty battery will give about 30 minutes of light.

When charging is complete, fold the crank back into the body of the flashlight.

The MT-023 flashlight seems reasonably durable at very minimum, but because of its all-plastic construction and that dynamo, I won't do the smack test on it. It would almost certainly become broken if I did.

Water-resistance should be fair at minimum, although it is not submersible or 100% waterproof. It should be at least weather- and sprinkle-resistant. But please try not to drop it in creeks, rivers, ponds, lakes, oceansides, docksides, puddles of snapping turtle 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 lightly bad weather.

You don't have to worry about me doing "the toilet test" on the MT-023, not only because the commode is shared by two others, but because the MT-023 would probably drown in the bowl.

Measures 188,100mcd on a Meterman LM631 light meter.
This high value is predominantly because the LED beams are focused.

I don't normally provide beam photographs on a wall with non-Luxeon flashlights, but this flashlight is bright enough for this type of picture. That red star thing is from an American DJ Laser Widow
