Last updated 10-07-11

This is the Peak LED Solutions CPF Special 1xRCR123A rechargeable cell 1xLuxeon LED flashlight.

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

There is one Luxeon III white LED in the head, and a single RCR123A cell inside the barrel powers the LED.

This flashlight will be known as the Ranier when it becomes available to the public in early-2006.


The light came to me almost ready to use, just needing to be fed the included rechargeable Li:ION RCR123A cell.

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 in the {vulgar term for feces}bowl, look at it all funny, yank that silver handle on the front of the cistern down, and flush it away...O WAIT, THAT'S THE GOOD PART!!! So just set it aside instead.

Tip the barrel into your hand so the discharged RCR123A cell falls out. Recharge the cell in the included charger.

Drop the charged RCR123A 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 freshly charged battery ya know.
Aren't you glad you didn't flush away that bezel now?

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

To charge the battery or batteries, plug the wall wart into any standard (US) household receptacle furnishing 110 to 130 volts AC 60Hz. Plug the small plug on the end of the wall wart's cord into the receptacle for it on the charging base. Insert one or two RCR123A cells into the charging cradle, orienting the cell(s) so the button-end (+) positive of them faces the (+) symbol embossed in the chambers of the charging base. The LED on the charging base should now be glowing red. This indicates charge in progress.
When this LED turns green, that means the charge cycle is complete, and you can now unplug the wall wart and remove the cell(s) from the charging base.

This kit also includes a "siggeret" lighter plug & cordset that you can use in leiu of the wall wart transformer, so you can charge the batteries in your vehicle.

According to somebody who has tested this, you can expect a runtime to 50% intensity of ~40 minutes per charge on a rechargeable Li:ION cell.

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 sides of the bezel and barrel 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 56F (13.3C) (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 cat 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.

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 constant power until the battery can no longer provide that power, then the intensity of the Luxeon 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 2005 CPF Special can also be used with a disposable CR123A cell and can be outfitted with a pushbutton tailcap switch (available as an optional accessory)...I'll tell you about these later on.

Test unit was sent by Peak LED Solutions, and was received on the afternoon of 12-19-05.

Product was made in the United States. A product's country of origin really does matter to some people, which is why I published it on this web page.

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