The Delta is our newest light and boasts the power of an Alpha in a smaller package.
Delta lights are assembled to order and may take up to two weeks to ship, depending on our current workload.
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.
The "Spun" finish is achieved by utilizing our shop-made magnetic finishing machine. A liquid filled bowl holds thousands of tiny stainless steel pins. A plate of magnets spin below the bowl at high RPM and violently agitates the pins. The raw aluminum parts are placed in the finisher and spun for 30 minutes. The pins break sharp edges and lightly peen the surface. After that, the lights are sent out for Electroless Nickel plating. The result is a smooth surface with a bright finish that preserves most of the raw machined texture.
Currently this finish is available in two body styles:
- Prometheus grooving: my trademark (radial grooves around the body)
- Fuller grooving (small axial grooves along the length of the body.
We are currently offering the following LED options:
- Nichia 219C (4000K) ~850+ Lumens / 92+ CRI
- Nichia 219C (5000K) ~950+ Lumens / 92+ CRI
- Nichia 319A (4000K) ~950+ Lumens / 80+ CRI
- 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.
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.
Packages include things like accessories, maintenance tools, and replacement parts.
If you are looking for a gift, I suggest package #2 (the "Apprentice") which includes everything you need to get started.
Package 1: Light ONLY
This is pretty self explanatory. A good option if you already own 18350 batteries and a charger that you are happy with.
Package 2: Apprentice (+ $30.00)
Dominate the dark with the basic package: light + battery + charger
- Delta Series light
- 2x18350 Keeppower 1200 Batteries
- Battery Case
- Foursevens USB Flex Charger (Lithium-ion and NiMH)
Package 3: Journeyman (+$65.00)
Maintain your Delta like a pro and avoid buyer's remorse about your button color. Includes everything in the basic package, but you also get:
- Maintenance kit (Nano-Oil + replacement o-rings)
- O-ring removal tool with rubber grip
- Three extra button colors of your choice
- Switch Tool (Pronged tool to aid in removal of the switch and retaining ring. Machined in-house!)
Package 4: Master Package (+$75.00)
The full boat. A good friend once told me, "two is one and one is none." He was right, don't get caught in the dark. You get everything above, but you also get:
- Spare UCL window (glass lens)
- Spare McClicky tailcap switch
All our lights are made in small volume to be functionally perfect, not cosmetically perfect.
Every custom flashlight is designed, machined, finished, assembled, and tested in my shop.
We use state of the art CNC machines, but a significant amount of hand finishing and assembly goes into each light. As a natural result, each light exhibits some cosmetic variation from one to another. Each light has its own character.
I do not intentionally remove "machining marks" from the lights because I like to retain some evidence of the process. I actually think machining marks are beautiful because they explain how the light was made. Each light has an experience and history even before it arrives in your mailbox, and some show it more than others.
During production, a light might receive a small nick, ding, or scuff. Aluminum is incredibly soft and it's very difficult to get a light through the dozens of manufacturing steps without a blemish of some sort. Sometimes a metal chip will get stuck between the part and the vise and leave a little dent. Even the paper transport cartons will scratch a polished or sand blasted finish before it's been plated.
When all the machining and finishing work is done, these lights are electroless nickel plated by a local plating company (sometimes dings occur here). This coating is extremely hard and wear resistant and will protect the light from now on, but at this stage any imperfections have been permanently "sealed" into the finish.
The point of all this is you should not expect to receive a light that is 100% cosmetically perfect. That's just not how low volume manufacturing works. If you can't accept this degree of uncertainty, you should stick with mass-produced brand ;).
