NightStick NSP-4640B FORGE™ Helmet-Mounted Multi-Function Flashlight

Product Description


The NSP-4640B Helmet-Mounted Multi-Function Flashlight is the most versatile choice for helmet-mounted hands-free lighting. The 4640 outshines the competition with its powerful 360-lumen tightly-focused flashlight and a beam distance rating of 218 meters (715 feet). The user can also choose a lower 180-lumen setting for increased runtime. The 4640 also features a 30-lumen for 30 hours Survival Mode.

The 4640 will fit on any Fire Helmet (or side-brim hard hat) regardless of whether it has an up-turned or down-turned brim thanks to the multi-angle mount that allows the user to fine-tune the exact light position and angle for optimal aim. This feature makes it possible to not only avoid goggles, face shields, and other helmet-worn gear but also place the light exactly where it’s needed. The 4640 is IP-X7 rated waterproof and meets the requirement for NFPA-1971-8.6 (2013). Power comes from 2 included CR123 batteries.
