The NSP-4650B Helmet-mounted Multi-Function Dual-Light™ Flashlight by Nightstick is the most versatile choice for helmet-mounted hands-free lighting. This light outshines the competition with its powerful 220 lumen tightly-focused Flashlight and a beam distance rating of 183 meters (600 feet). The user can choose from two additional lower lumen settings of either 100 or 30 lumens for the ability to dial-in just the right amount of concentrated light.

It gets better. Located just below the Flashlight, and perfectly angled at 45 degrees to the flashlight, is a user-selectable brightness Floodlight. Since Floodlights don’t have a reflector, the light pattern doesn’t have a bright center spot, instead the Floodlight’s soft unfocused light pattern is perfect for lighting up nearby objects. Reading the gauge on a respirator, inspecting or working on things within arm’s reach and illuminating the ground as the user walks are now possible because of the integrated Floodlight. Brightness settings for the floodlight give the user the choice of either 100 or 50 lumens for typical use, as well as a “Survival” mode at 15 lumens for emergency situations when having less light that runs for 60+ hours might just make the difference.

Additionally, in Dual-Light™ mode (both the Flashlight and the Floodlight turned on at the same time), the user can light up the distance AND the ground at the same time for maximum versatility and user safety. The 4650 also has a green, rear facing LED light so that others can easily identify team personnel in smoke-filled or dusty environments. The 4650 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 adjustment feature that allows the user to fine tune the exact position and angle of the light. 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 4650 is IP-X7 rated, waterproof, and meets the requirement for NFPA-1971-8.6 (2013). Powered by two CR-123 batteries (included).
