This is the Peak LED Solutions 1xCR123A 1xLuxeon Star 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 is 1 white Luxeon LED in the head, and a CR123A lithium cell inside the barrel powers it.

It is labelled as being the Atlantic, which would consist of flashlights that use one CR123A cell and have 1 Luxeon Star LED in their business-ends.


The light came to me ready to use, with a Sanyo brand 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, and stomp on it with old or used bowling shoes...O WAIT, YOU'LL NEED THAT!!! 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 hit 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 some very, very, very light scuffing on the side of the tailcap where it was struck), and it still works correctly too. Very few flashlights are damaged or destroyed by this test however; maybe I need to come up with something even yuckier.

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 three minutes in the cistern (toilet tank) in about a foot of water at 54F (12.2C) (to simulate a user dropping it into a creek), I dried the outside off with some toilet paper, unscrewed the bezel, and there was a little water inside the barrel. So yes, weatherproof, but no, not submersible.

If it falls into shallow water, just shake it off and keep going. If it falls into seawater or if the dog goes #1 on it, take it apart as you would for a battery change, douche the parts off with fresh water, and set them in a warm, dry place for at least a day to be sure it's all the way dry before you reassemble and use it again. You don't want your Peak to smell like seashells or old dog pee when you go to use it next.
You should have no trouble at all though using it in bad weather.

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.

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 Luxeon LED constant power until the battery can no longer provide that power, then the intensity of the LED 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 a 1.2 watt white Luxeon Star LED, which produces a beam with a slightly cool white central hotspot and a soft, white corona. This is a pretty typical beam out of a white LED flashlight that uses a Luxeon LED and a smooth reflector.

This makes the Atlantic the brightest Peak LED Solutions product I've tested to date.
