Delivering 700 lumens of white light from a single SF18650B rechargeable battery, it produces a powerful 100,000 candela beam capable of reaching targets up to 632 meters away.

Constructed from aerospace-grade, hard-anodized aluminum, this weapon light offers exceptional durability while maintaining a lightweight profile at just 5.9 inches in length. The Z68 click-style tailcap provides reliable ambidextrous on/off activation, and an IPX7 waterproof rating ensures dependable performance in wet conditions.
