Delta Flashlight Special Edition
Notes on this drop: Happy May the Fourth! Meet the Delta Spathi: A fully modular Delta that can convert between 18350 and 18650 batteries. The body is made from 3 separate sections. Simply remove one of the end-sections to convert to 18350. The center section is always required, but you can swap out either end section and customize the appearance to your liking. Eventually we plan to launch different style body tubes, heads, and tailcaps so you can lego your own look.
This Spathi is bead blasted and then buffed out on the high spots. We always nickel plate aluminum, but it just didn't look "right" in this application, so we are going raw! Over time this will also allow for developing a more worn-in look that's appropriate to the canon.
You MUST NOT (EVER) use 2x18350 batteries in series. This will destroy the driver and possibly cause a fire and/or explosion !!!

SPECIAL EDITIONS: FIRST COME, FIRST SERVED 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. These unique, and typically one of a kind, lights go up for sale here. Sign up on the Blue Label wait list and you'll receive an email when we stock Blue Label lights. We generally have a drop every month, and they go fast!
The Delta is our newest light and boasts more power than an Alpha (thanks to the triple LED) in a smaller package. I held off making an 18350 triple for years. It became the format de jour and seemed like the segment was too crowded. However, you dear customers are persistent and I caved. Of course I couldn't just make "another" 18350 light, so I created the Delta to set the standard for the category.
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.
Launched in 2018, I took my previous 7 years of flashlight design and manufacturing experience and crammed it into the Delta flashlight. It inherits everything that is legendary about the Alpha, and delivers it in a smaller EDC package.
I wanted to create something special, and I leaned heavily on engineering (not fads) to accomplish that. The exposed fins on the solid copper pill transfer heat directly to your hand and the environment instead of trapping it inside the light. This also allowed me to use 6/4 titanium (on titanium lights) without paying the performance penalty characterized by the poor thermal conductivity of titanium alloy. The Delta was also our first light to use a graphite thermal pad that is now standard on all Alphas and Deltas. User swappable optics also makes the Delta much more customizable.
You can't have everything though. The 18350 battery is 1/3 the capacity of the Alpha (18650) battery. You get the same performance but at the expense of reduced run time. However, if you select the Journeyman or Master package, you get two batteries so you aren't left in the dark. The Delta is a pocketable EDC light where the Alpha is a (just) pocketable workhorse.
