UM2-A-BK 084871324458
The new UM2 is much more than just a higher-output version of our classic U2 Ultra™ LED flashlight. Yes, the UM2 features the same no-look selector ring that provides quick access to six preset output levels ranging from a long-runtime five-lumen setting all the way up to an impressive high-output setting of 600 lumens—all activated with just a click. But this new model features a one-of-a-kind TIR optic that creates a beam that’s a cross between the high-intensity patterns produced by our patented TIR optics, like that found on our Backup® models, and the broader but still-far-reaching reflector-focused beams created by our popular Fury models. This unique TIR lens forms a smooth beam optimized for both range and peripheral illumination. The UM2 has a lightweight, durable Mil-Spec hardanodized aluminum body—that’s been completely redesigned—and a heavyduty pocket clip that permits multiple carry options. It keeps you in control.
