The Peak LED Solutions "Pacific" is a cute little keychain light which utilizes a Luxeon I LED and a regulator circuit in tandem with a single AAA alkaline cell to produce good output for over 2 hours. Two body materials are available - Type III anodized aluminum (reviewed) and solid brass, with stainless steel expected soon. Additional bodies are available, including a 2 AAA body, an AA body and a CR2 body.

(packaging example - unit shown is not the same as unit reviewed)

The body of the unit is machined aluminum with a Type III anodize finish - very tough stuff. Three bands of checkering surround the body. There are 6 flat facets machined into the side of the head that go from the bottom of the head to the half-way point. At the very front of the head are 3 grooves. At the tail end of the light is a removable keyring/lanyard attachment post. It can be unscrewed from the body to provide a flat bottom for tailcap standing. An O-ring provides resistance to prevent the tail post from unscrewing by itself, but the body is sealed regardless of whether the post is in place or not.

The bezel contains a reflector, Luxeon I LED, and a current regulating circuit (the best kind of regulator) to provide constant energy to the LED over the usable life of the battery. The smooth silvered reflector provides a surprisingly nice beam.

Output is nice and smooth. You'll find a central spot with a fading corona surrounded by a wide spillbeam. Overall output is more than sufficient for common close tasks. The beam itself is in the form of a smooth spot with a tapering corona and wide spillbeam. The color of the light is excellent. It was white with no tinting at all in the sample tested. Overall output with just one AAA cell (reading taken with new cells) is better than that of a Minimag AA or AAA.

Runtime Plot: With a single alkaline AAA cell, you should get about 1.5 - 2 hours of good light before you see a sharp dropoff as a result of the light dropping out of regulation. After that the light output diminishes over time, hitting 25% at about 6 hours. With the optional 2 AAA cell body you'll receive very good regulation from two alkaline AAA cells for about 2.5 hours before the light drops to a very low level. This long, dim "tail" gives you enough light to root around and find replacement cells for your light, or provides emergency level lighting for a long period of time

To turn the light on and off, simply twist the bezel. Tighten for on, loosen for off. Turning resistance is provided by a single O-ring in a groove which is quite sufficient to prevent accidental turning.

The light is completely sealed with O-rings and other rubber seals for water resistance. I'd classify it as dunkable. Shake it off and keep going.

Ergonomics: It's a tiny little light but easy to use. Easy to grip, easy to operate.

Size compared to a common 2AA aluminum light. 2-AAA body in middle for size comparison.

A single AAA alkaline cell powers the light, but you can use NiMH or L92 lithium AAA cells. To change the battery just unscrew the head, drop out the old cell, and place a new one in negative first.

Accessories: A pocket clip is included with the body. It's a chromed clip similar to a ballpoint pen, but stronger.

What I Liked: Water resistant, Tough/impact resistant, Semi-Regulated, Good battery life, Good output, Easy battery change, Lightweight, Removable lanyard lug

What I Didn't Like: Nothing

Other Things I Noticed: Nothing

Conclusions: Great little pocket/keychain light. Bright, long lasting good output, and built pretty tough. Extremely lightweight, very compact. A solid pocket light with sufficient light and runtime for almost any common tasks where you would use a small flashlight. Where do I see it being used? I think this would make a good replacement for a AA Minimag, especially with the two-cell body.
