This is the 9 white LED flashlight I purchased on Ebay sometime back. It comes in an aluminum body, has 9 white LEDs in its bezel (head), uses three AAA cells in a carriage in its barrel, and has a rubbery pushbutton on/off switch on its tailcap.

To use this flashlight, feed it first (see directly below), and then you can go to town.

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



To change the batteries, unscrew and remove the tailcap, throw it to the ground, look at it all funny, cock your head like a puppy that doesn't understand what it had just been told, and stomp on it with old or used bowling shoes...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 stomp on that tailcap now?

Current draw measures 66.1mA on my DMM's 400mA scale. This equates to just ~7.3mA per LED.

Since performing "The Smack Test" would probably void the warranty (which I'll need), I will not do that test just yet.

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 gila monster 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.

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 light output is considerably less than what I'd expect out of a device with nine LEDs in it.

TEST NOTES:
Test unit was purchased on Ebay and was received on 11-26-05. It is defective; the contact spring in the tailcap was rattling around loose inside there; intensity measurements were performed by bridging the center contact on the battery carriage and the barrel with a knife blade.

Looks like I'll have to cash in on that lifetime warranty if I am able to do so.

Product was made in China. A product's country of origin really does matter to some people, which is why I published it on this web page.
