Meet the Delta, the latest light from Prometheus

Compact, powerful, awesome.

SPECIAL EDITIONS: first come, first serve

These lights are our opportunity to play around a little bit. The selection always changes and we may (or may not) ever produce a specific combination again.

Delta lights are assembled to order and may take up to two weeks to ship, depending on our current workload. 


Black Marble: Wabi Sabi is the Japanese tradition of imperfection. This finish was developed using our Alpha Pen Base Station. I attempted to achieve perfection by embracing the lack of it. This finish is our trademark Electroless Nickel plating over aluminum, 4 step ultrasonic cleaned, kiln dried, oxidized black, vibratory finished, and baked for 2 hours to harden the far my favorite finish to date...and by far the most labor intensive. We retain the luster of nickel, the contrast of darkness, and an imperfect finish that is unique to each and every light like a fingerprint. 

    The Delta is our newest light and boasts the power of an Alpha in a smaller package.

    I've taken my last 7 years of flashlight design and manufacturing experience and crammed it into the Delta flashlight. One major upgrade is our graphite thermal pad with about 5x thermal conductivity compared to pure copper! The exposed fins on the solid copper pill transfer heat directly to your hand and the environment instead of trapping it inside the light. 

    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

    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. 

    LED Options: 

    We are currently offering the following LED options: 

    1. Nichia 219C (4000K) ~850+ Lumens / 92+ CRI
    2. Nichia 219C (5000K) ~950+ Lumens / 92+ CRI
    3. Nichia 319A (4000K) ~950+ Lumens / 80+ CRI
    4. Nichia 319A (5000K) ~1100+ Lumens / 80+ CRI


    The Delta is assembled with your choice of optical beam angle. The narrow optic will give you the most range and smallest hotspot. The wide optic will give broad flood of light over the entire beam, with a slight bias towards brightness in the center. 

    1. Narrow: 26 Degrees beam angle
    2. Medium: 33 Degrees beam angle
    3. Wide: 46 Degrees beam angle

    Glow in the dark insert:  

    You may choose to include (or omit) a glow insert around the LEDs. This insert is made from the highest quality glow material and is manufactured in-house. It's bright enough to be used as it's own light source for several minutes (in total darkness) after being charged by running the light on 100% power for a few seconds.
