The Preon P1 MKIII from FourSevens by Prometheus Lights is a sleek, simple and functional every day carry flashlight with 4 modes of operation for every situation and a lightweight construction that carries like a pen while delivering up to 100 lumens of output. This version is type three hard anodized black aluminum and carries via a robust stainless steel pocket clip.

Brand new direct from FourSevens.

Operation: Easy access tail cap switch clicks on/off with momentary on via half press. There are six Configurations that are user programmable allowing you to customize your UI for simplicity or complexity as the situation demands. The new Burst Mode was adopted from the flagship Prometheus Alpha Flashlights. It allows direct access to maximum output at any time by cycling off/on twice, very fast. This gives you maximum output when you need it but conserves battery life, utilizing the standard high mode for normal use.

Body: Made from solid 6061-T6 aluminum with Type-III hard anodizing the Preon P1 MK III is tough while maintaining a very light weight. The dual, anti-reflective coated Optical-grade glass lens is paired with the Nichia 219c LED to provides enhanced directional illumination and clean, even, 5000K / 90+CRI output. Carries via an improved stainless steel pocket clip for lens down carry.
