0.5 Watt White LED Flashlight, retail $14.95 (
Manufactured by Suncke
Last updated 06-11-07

The Suncke Light flashlight is an aluminum-bodied light that has a single 0.5 watt white LED in the end, powered by a single AAA cell held in its barrel. The LED & reflector are protected by a glass window (or "lens" if you prefer).

A DC-DC inverter circuit in the flashlight's head boosts the ~+1.5 volts from the AAA cell to the ~+3.6 volts the LED needs.


Getting this light to work is as easy as turning the head clockwise (as if tightening it) until it lights up; turn it the other way to turn the LED back off.

To change the batteries in this flashlight, unscrew and remove the bezel (head), dash it to the ground, and stomp on it with spiked golf shoes...O WAIT!!! THAT'S THE GOOD PART!!! So just set it aside instead.

Tip the open end of the barrel into your hand, and dispose of or recycle as you see fit the used AAA cell that comes out.

Insert a new AAA cell in the barrel, orienting it so its button-end (+) positive faces outward, and screw the bezel back on. Unscrew it slightly when the light springs to life so you don't just waste that new AAA cell.
Aren't you glad you didn't stomp on that bezel now?

Unable to measure current usage due to how the product was constructed.

I'm running a battery discharge analysis on the 0.5W Flashlight right now.
Assuming I don't bump something and queer the test, the machine should poop out a chart on the day of 06-11-07.

The test got queered, so I started a new one with a new AAA cell at 1:19pm PDT.

Battery disacharge analysis
Here is the battery discharge analysis.
It ran from 1:19pm PDT to 2:52pm PDT; a total of ~1 hour 20 minutes to 10% intensity (the extra time shown on the right hand side of the chart is because it was below 10% intensity).

I beat the living tweedle out of it (gave it ten firm whacks against the concrete floor of a patio; five whacks against the side of the tailpiece and five whacks against the side of the bezel), and found the expected damage. There is some VERY MINOR gouging to the bare Metalcherrymon - er - the bare Metaldatirimon - um that's not it either...the bare a sec here...THE BARE METAL (guess I've been watching too much Digimon again! Now I'm just making {vulgar term for poopoo} up! ) on the side of the tailpiece and bezel where it was struck. No optical or electrical malfunctions were detected. It still works as well now as it did when I received it two days ago.

I tried to cut through the window with a folding knife, and I was not successful. This tells me it is made of glass, not plastic.
Would I really try to chop up the window of a perfectly good flashlight?
You bet your sugar-coated toilet muscle (sweet patootie) I would, if it's in the name of science.

This flashlight is splash- and weather-resistant at absolute maximum, but I do not believe it is submersible. There's an O-ring on the bezel, but I don't know exactly how effective it is. It has a "loose" feel to it, so it may not provide 100% water-resistance. So please try not to drop it in creeks, rivers, ponds, lakes, oceansides, docksides, puddles of concentrated camel urine, 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.

If it fell in water and you suspect it got flooded, disassemble it as you would for a battery change, 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, if somebody squirted a Massengill brand post-menstrual disposable douche at it (and hit it with the douche), or if somebody or something peed on it, rinse all the parts out with fresh water before setting them out to dry. You don't want your flashlight to smell like seashells, flowers, or urine when you go to use it next. Besides, salt (from seawater, pee, or disposable douches) can't be very good for the insides.

I'm not familiar with the LED used in this flashlight, so please no emails asking this.

There is a wide band of knurling (cross-hatch shaped texturising) on the barrel and on the bezel (head); this helps to aid in retention (the ability to hold onto the flashlight when your hands are cold, oily, or soaked with water, cold coffee, diet Pepsi, gasoline, piss, Fanta, pine sap, melted vanilla ice cream, etc.)

The light can be stood on its tailcap to beam onto a light-colored ceiling for use as an electronic "candle".
