Prometheus Lights Delta - Copper (Custom)

Compact, Powerful, Awesome

It’s always an exciting day in the office when Jason at Prometheus Lights releases something new. You just know it’s going to be good, and the Prometheus Delta flashlight does not disappoint. Bringing big innovation in a small package, the Prometheus Delta is everything you expect and then some.

Running on a single 18350 battery, the Prometheus Delta is pleasantly compact and measures in at only 1” (2.54 cm) x 3.75” (9.5 cm), making it perfect for your everyday carry. The triple 4000K Nichia 219C emitters (92+ Color Rendering) lets you see better in the dark while easily hitting ~800+ OTF lumens.

The biggest innovation of the Prometheus Delta is the use of graphite thermal pad upgrade. The most common problem with high output flashlights is that it gets really hot, really quickly. So while your flashlight might be able to put out 1000 lumens, it can only do so for a very short span of time before it gets too hot to hold. 

The graphite thermal pad in the Prometheus Delta has about 5x the thermal conductivity compared to pure copper. In addition, the exposed fins on the solid copper pill transfer heat directly outwards into the environment instead of trapping it inside the light. This means that the heat will be dissipated much more efficiency, allowing you to maintain the highest output for longer.

The body is made from solid C145 Tellurium Copper with the trademark Prometheus radial grooves around the body). And finally, the Prometheus Delta comes with the world-class Icarus LED Driver (3.4A max) that is 100% designed, programmed, and manufactured in the USA. In addition, it comes with the industry-leading McClicky Switch, UCL glass lens, and the perfectly tensioned Prometheus Lights titanium clip.

Compact, powerful, and impeccably crafted - the Prometheus Delta is the culmination of Jason’s 7 years of flashlight design and manufacturing experience, all crammed into a single, cohesive, masterpiece that’s designed for real-world use. If you want to experience the future today, you need to get your hands on one of these, pronto.

Note: We highly recommend picking up a Prometheus Lights Alpha Apprentice Package, which is compatible with the Delta.
