This is the Peak LED Solutions 1xAAA 3xLED flashlight.
It is labelled as coming from the Matterhorn Collection.

The Peak comes in a black anodized body; probably with a type III hard anodizing.
Another Peak 1xAAA 3xLED flashlight I received with this group comes in a brass body.

There are 3 white LEDs in the head, and a single AAA cell inside the barrel powers them.


The light came to me ready to use, with a Panasonic Industrial AAA alkaline 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 1/4 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) throw it in the toilet, and flush 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.
Aren't you glad you didn't flush away that bezel now? ;-)

The brass version measures 122mA on my DMM's 2A scale.
I was not able to measure the black HA version because the anodizing is nonconductive.

Because it was requested, I started a battery discharge analysis of the black HA Peak a short time ago (approximately 5:20pm PDT 06-18-04); the machine should poop out a chart late this evening or tomorrow morning.

And here's the battery discharge analysis.
Runs for 1 hour 50 minutes to half-intensity, 9 hours 20 minutes to 10% intensity.
Test was run for 14 hours.

I used the Panasonic Industrial alkaline cell that came with the flashlight.

Unit can be turned off and back on even in this nearly discharged state.

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 whapped it against a steel rod ten times (five on the barrel, and five on the bezel) and did not damage it in any way that I can detect.

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.

I tried to cut the black HA Peak with the blade of a Swiss army knife, and was not successful. This tells me it probably has a type III hard anodized finish ("HA-III" as us flashaholics know it).
Would I really try to cut up a brand spanken new flashlight?
You bet your sweet patootie I would, if it's in the name of science.
The brass Peak has no exterior finish of any type, and I would probably be able to put a visible cut in it. Let's see what happens...BRB...ok, I unscrewed the tailcap of the brass Peak, and tried to put a cut in the exposed lip, and was successful. But I do this in the names of science and accuracy, so I guess it's alright.

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 at 82F (27.7C) (to simulate a user dropping it into a creek), I dried the outside off with some toilet paper, unscrewed the bezel, examined the flashlight, and found 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 LEDs, 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) when you get a chance and it ought to be as good as new.

There is a light knurling (diamond-shaped texturising) present on the barrel 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 bezel (head) has 6 flats machined into it. Although this does not function as an anti-roll device, it does help a bit to aid in your grip when you turn the flashlight on and off.

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. The black HA version has a stainless steel split ring; the brass version has a brass (non-magnetic) split ring.

The very tail end is removeable (by unscrewing it), to allow the flashlight to be affixed to a large and sturdy magnetic clamp assembly. This assembly was included; see the photograph directly below:

This clip has a large, heavy-duty clamp with very strong jaws, a large ceramic ring magnet in its base (under that shiny metal thing at the bottom), and a flexible arm that can be positioned pretty much anywhere.
Once the flashlight's very tail end is unscrewed and removed, the flashlight can then be screwed onto the end of the red arm, and pretty much aimed wherever you need light. In this picture, a 1xCR123A 7xLED brass Peak is shown. But this flashlight fits on the arm the exact same way.

Note: The brightness difference between the two units is NORMAL,
and does not indicate any problem whatsoever with the flashlights.
This type of variation is quite common in individual LEDs.
To the eye, there is no noticeable difference between them.

Test unit was sent by MJ of Peak LED Solutions along with three of their other flashlights and a magnetic clamp thingie, and was received on 06-14-04.

Here's an example of the retail packaging these flashlights come in.

From a posting on Candlepower Forums by MJ:
At this time we are working on a resolution for the battery rattle. If you would like you can send the unit back to us to be replaced or refunded. The resolution to this problem should be available with in 2 weeks as soon as this is available we will also be sending this out to all customers prior to this being done.
