This is the Peak LED Solutions 1xCR123A 7x5mm "Snow-White" LED flashlight.

This unit comes in a black aluminum body, with a Type III hard anodized finish on it, or "HA-III" as us flashaholics know it.

There are 7 "snow-white" white 5mm LEDs in the head, and a CR123A cell inside the barrel powers the LEDs.

It is labelled as being the McKinkey, which would consist of flashlights that use one CR123A cell, and have 7 5mm LEDs in their business-ends.


The light came to me ready to use, with a Sanyo brand lithium CR123A 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 1/8 of a turn from the fully tightened position.

To feed your light, unscrew the bezel (head) until it comes off (don't worry about losing parts or bulbs) throw it to the ground, look at it all funny, cock your head all wierd, and stomp on it with old or used tennis shoes...O WAIT, THAT'S THE GOOD PART!!! So just set it aside instead.

Tip the barrel into your hand so the used CR123A cell falls out. Dispose of or recycle the used up old cell as you see fit.

Drop a new CR123A 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 that brand spanken new battery ya know.
Aren't you glad you didn't stomp on that bezel now?

Unable to measure current usage due to how the flashlight is constructed.

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 performed that terrible smack test, by hitting it against the corner of a concrete stair 10 times (5 against the tailcap, 5 against the bezel), and did not damage the flashlight in any way I can see (other than causing some very, very, VERY light scuffing on the side of the bezel where it was struck), and it still works correctly too. Very few flashlights are seriously damaged or destroyed by this test however; maybe I need to come up with something even more awful.

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 Toilet Test" and see what happens...BRB...ok, after submerging it for one minute in the cistern (toilet tank) in about a foot of water at 69F (20.5C) (to simulate a user dropping it into a creek), I dried the outside off with some bunghole wipe, unscrewed the bezel, and examined the flashlight. No water was found in it.

If it falls into shallow water, just shake it off and keep going. If it falls into seawater or if the horse pisses on it, take the garden hose to it or douche it off under the faucet - good as new!!!

There is a light knurling (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 what I believe is a 12-sided shape machined into it. Although this does not function very effectively 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. If you wish, you can choose the barrel with the flat bottom, so it will be more comfortable to carry in your pocket.

The very tail end is removeable (by unscrewing it), to allow the flashlight to be affixed to a large and sturdy magnetic clamp assembly that you can get from Peak LED Solutions.

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 (a Peak brass CR123A cell 7xLED flashlight is shown in this photograph), and pretty much aimed wherever you need light.

You can also stand the Peak on its tail end when this piece is unscrewed; you can stand it on a dresser, counter, table, or other flat surface and let the light reflected off the ceiling light up the entire room.

There appears to be a regulation circuit inside the bezel (head), potted in a black epoxy compound. This circuit feeds the LEDs constant power until the battery can no longer provide that power, then the intensity of the LEDs rather quickly falls off. This is your cue to change the battery. You aren't just plunged into instant darkness, as can happen with some other regulated flashlights.

The flashlight uses seven 5mm "snow white" white LEDs, which produce a beam with a pure white central hotspot and a soft, white corona. This is a pretty typical beam out of a white LED flashlight that uses 5mm white LEDs; but much less bluish than is normal for white LEDs.

I don't normally furnish photographs of non-Luxeon
flashlights at 15', but this flashlight is bright enough.
As you can see, it was 11:26 when this photograph was taken.

Test units of this and three other flashlights were sent by Peak LED Solutions, and were received late on the morning of 07-16-05.

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