The Peak LED Solutions 2xN 3xLED flashlight has 3 white LEDs in the head, and two N cells inside the barrel power them.

Ths unit comes in a brass body, with no surface treatment that I'm aware of.
Because the unit comes in a brass body, it will feel heavier than a flashlight in an aluminum body. I do not at all consider this to be a problem though; the unit actually feels rather stout and substantial in the hand.

This flashlight is labelled as coming from the Alpine Collection - flashlights that run from two N cells and have one or three LEDs.


The light came to me ready to use, with two Panasonic Heavy-Duty N cells 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 N cells fall out. Dispose of or recycle them as you see fit.

Drop two new N cells 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 brand spanken new batteries ya know.
Aren't you glad you didn't flush away that bezel now? ;-)

Measures 176mA on the Panasonic Heavy-Duty N cells it was supplied with.
If you wish to measure the current consumption of yours, you'll have to press down firmly on the top of the top battery with your meter probe, so the (-) end of the battery will press down on the battery rattle prevention device and make contact with the small projection on the bottom of the barrel for it.

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 LEDs themselves produce the vast majority of this flashlight's beam. So if the Peak's business-end becomes dirty or develops a patina, you do not have to worry about it.
If you wish to shine the flashlight back up, a common brass polish like Brasso may be used.

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.

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 sink test and see what happens...BRB...ok, after submerging it for three minutes in about a foot of water at 70F (21.1C) (to simulate a user dropping it into a creek), I dried the outside off with some paper toilets, 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 the dog lifts his leg 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 are four bands of 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 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 with a previous Peak flashlight; 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.

You can also stand this flashlight on its tail for ceiling illumination when the tailpiece is removed. This is a handy feature to have in almost any flashlight; I'm glad it was included on this one.

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.

Measures 35,000mcd on a Meterman LM631 light meter.

Test unit was sent by MJ of Peak LED Solutions along with twelve of their other flashlights, and was received on 08-04-04.
