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, 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 360-degree pivoting mount that allows the user position the light at the optimal angle. 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). Power comes from 2 included CR123 batteries. (Not compatible with rechargeable batteries.)
I have used all different lights and this is my favorite. The people at my station use pelican, nighthawk and stream light. This is just as sturdy, mounts similar and just as bright. I've had no problems with the function of the battery compartment, and the c123 lithium have lasted for a while before I had to change. The buttons are easy to feel with fire gloves on, a dimmable button would be nice to conserve power but not needed. My most favorite function is the floor light, it's TRUE that it isnt as bright as the main light but I'm only using it to navigate and not blind others like we most often do. I would have given this light more than a 5 out of 5 if I could.BStiteler (03.2020) via Amazon.com
