These are the Alphas that started it all!
These three Blue Label finishes have been out of production for several years. Now they are back in limited quantities!
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.
As with standard Alphas, these lights use an 18650 battery, but we are also rolling out our "shorty" bodies that can convert an Alpha to 18350. The shorty bodies are only available as a separate accessory at this time.
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. Enough talk, let's get to the details.
