The Concept 1 brings some new features to the table. With a side switch that is placed on the outside to keep the length of the light short, this Concept 1 has two modes that are activated from Standby, Turbo and Strobe. Both shine up to 1800 lumens out of the LED after three clicks, powered by just one 18650 (not included). At a 90° angle from the switch is the pocket clip, bolted into place. For added usage, the Concept 1 has a magnetic tailcap, allowing it to stick to any ferrous surface.

This light is machined from aerospace-grade aluminum alloy, given a military-grade hard-anodizing to be durable against impacts from 1.5 meters up. The lower half of the Concept 1 is diamond-knurled for an easier grip over longer periods.
