The 4650 will fit 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.s

The NSP-4650B Helmet-mounted Multi-Function Dual-Light™ Flashlight is the most versatile choice for helmet-mounted hands-free lighting. The 4650 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 at 100 or 30 lumens for the ability to dial in just the right amount of concentrated light.

But the 4650’s lighting options don’t stop there. 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 thanks to the integrated Floodlight. Brightness settings for the floodlight give the user the choice of 100 or 50 Lumens for typical use, and a “Survival” mode at 15 lumens for emergencies when having less light that runs for 60+ hours might make the difference.

Additionally, in Dual-Light mode (both the Flashlight and the Floodlight turned on simultaneously), the user can light up the distance and the ground simultaneously for maximum versatility and user safety. The 4650 also has a green; rear-facing LED light so that others can quickly identify team personnel in smoke-filled or dusty environments.
The 4650 will fit 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 avoid goggles, face shields, and other helmet-worn gear and 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). Power comes from 2 included CR-123 batteries.
