Same awesome, smaller size!
I've been selling "shorty" bodies for Alpha flashlights for years, but this is the first time we've offer them as stand-alone lights. This variant is a standard Alpha with a short body that accepts and 18350 IMR battery.
Battery type is IMR 18350 ONLY. Standard lithium ion batteries (non-IMR chemistry) in any size CANNOT handle the 3.4A current drain. Using these batteries are DANGEROUS. Appropriate batteries can be purchased here.

Alpha lights are assembled to order and may take up to two weeks to ship, depending on our current workload.
The Alpha wasn't always a classic, but my three original finishes are back from a very long hiatus. basically I wasn't able to keep up with the workload, but the current Prometheus team numbers six souls and we can get a lot more done. An 18350 battery is 1/2 the size but only 1/3 of the overall capacity. This makes the 18650 great for a work/utility/duty light when you need to use it regularly. The smaller 18350 is more suitable for EDC (Every Day Carry) and casual use.
I've been working on this driver for over two years. It's simple, powerful, and full of features even the most demanding flashlight enthusiasts will appreciate. A maximum current of 3.4 Amps delivers class-leading power and an advanced software platform lets you make Icarus a reflection of your unique preferences by programming it any way you like...
This driver is 100% designed, programmed, and manufactured (in the USA) just for me. Until now, I've been limited by "what is available," but Icarus is the realization of a long standing goal. No expense is spared, no shortcuts taken, no compromise accepted. I'm proud to put the Prometheus stamp on this driver as the crowning jewel of the Alpha platform.
