The Peak LED Solutions 1xAAA 1xLED flashlight I'm presenting to you today is a prototype; it features an all brass body and a red LED, feeding from a single AAA cell. It is similar to the Arc-AAA flashlight, in that it is the same shape and size as one, uses the same battery, and turns on & off like one.

As I already said, it comes in an all brass body, and has no finish that I'm aware of. So it will develop a patina over time that can either be left as is, or polished back to shiny brass with a brass polish.


The light came to me ready to use, with a Panasonic Industrial alkaline AAA cell already installed.

To turn the light on, twist the bezel (head) clockwise (as if tightening it). And to turn the light off, turn the bezel counterclockwise (as if loosening it) about 1/8th of a turn from the fully tightened position.

To feed your light, unscrew the bezel until it comes off (don't worry about losing parts or bulbs) and throw it away...O WAIT, YOU'LL NEED THAT!!! So just set it aside instead. ;-)

Tip the barrel into your hand so the used AAA cell falls out. Dispose of or recycle it as you see fit.

Drop a new AAA cell in the barrel, flat-side (-) negative first, so the button-end is showing. Screw the bezel back on, and you're finished. Oh, and unscrew that bezel slightly when your Peak springs to life. You don't want to waste a brand spanken new battery ya know. ;-)

I don't have battery usage information here yet. The machine is still doing a chart for another product, and a second product is ahead of the Peak in the queue.

Current consumption is 71mA. This is for the red LED version.

Ok, as of 05-17-04, I now have the Peak on the battery discharge analysis machine. It should poop out a chart in the next day or so.

The battery test is now finished, so here's the chart:

Runs for 8 hours to half-intensity, and just over 22 hours to 10% intensity, when I stopped the test.
This test was done with an alkaline cell; the Panasonic Industrial alkaline that came with the light.

The brass Peak will develop a patina over time; this should have no to very, very, very little impact on the beam produced by this flashlight, because the LED itself produces the vast majority of this flashlight's beam. So if the Peak's reflector becomes dirty or develops a patina, you do not have to worry about it.

Picture comparing the Peak (bottom) and Arc-AAA (top).

As you can see from the picture above, the Peak is very similar in size and shape to an Arc AAA, another flashlight that has a single LED and uses a single AAA cell to power it.
The model I'm testing for you today outputs a red light, not white. So I cannot compare it with an Arc or any other white LED flashlight to see how it stacks up.

The Peak is very durable, and ordinary flashlight accidents (dropping it, whapping it against a doorframe or car door in alarm, sitting on it, stepping on it, sucking it up the vaccume cleaner, etc.) will not damage it. I usually whap flashlights against a steel rod to determine "smackability", but since that rod is on a table hosting a running test at the moment, smacking the Peak against that rod is likely to queer the test, and I don't want to do that. Not on a test that's been running for three days anyway. So that part of my durability testing program will have to wait.
I did smack the Peak against the front of this table several times, but since this table does not have metal on it that I can reach, this test really does not substitute for the steel rod smack test I normally do.

(Edit 05-18-04)...I did that smack test today, and surprise, surprise, surprise...the Peak was not damaged by this punishment. I even did it without the battery so the flashlight barrel could more easily become crushed, and that did not happen. Examining the Peak after this test did not reveal any scratches or dings on it.

I ran over the Peak with a 400lb electric wheelchair four times, and as I expected, no damage was found and the Peak still works properly. Just to be fair, I ran over an Arc-AAA PE with the same wheel (the left rear drive wheel of the chair) the same number of times, and didn't break it either.

The Peak has an O-ring that seals the bezel against the barrel, so it should be fully weatherproof, and maybe even submersible to at least a foot or two. Let's try the bathroom basin test and see what happens...BRB...ok, after submerging it for three minutes in about a foot of water (to simulate a user dropping it into a creek), I dried the outside off with some bungwipe, unscrewed the bezel, and there was no water inside. So yes, weatherproof and submersible to at least 1 foot.
I also tried suctioning the bezel by itself to be sure no leakage occurred around the LED, and no leakage was detected.
If it falls into water, just shake it off and keep going. If it falls into seawater or if something pees on it, douche it off with fresh water, shake it off (or dry it off) and it ought to be good as new.

There is a light knurling (texturising) present on the barrel and bezel of the Peak; this helps to aid in retention (the ability to hold onto the flashlight when your hands are cold, wet, or oily). This knurling is not aggressive (sharp), so it won't cut a hole in your pocket if you carry the Peak that way.

The Peak is equipped with a small split ring on its tail, so you can affix it to a keychain and carry it that way if you desire.

Because of the narrow beam, the light does have increased "throw" over other 1-LED flashlights. But if the red color pisses you off, you may not like the Peak compared with flashlights that have other color LEDs or white LEDs in them. Choose accordingly.
Remember, this is a protoype; publically-released builds could have a different LED in them down the road.
