SKU CH-EWQ1-BM145

Helmet-mounted LED flashlight with 360, 180 and 30 lumen modes, IP-X7 waterproofing and up to 715-foot beam distance

  • Hands-free helmet mounting for secure, adjustable aiming
  • 360-lumen high beam reaches 715 feet for long-distance visibility
  • 180-lumen medium setting balances brightness and runtime
  • 30-lumen survival mode runs 30 hours on two CR123 batteries
  • IP-X7 waterproof rating withstands immersion in wet conditions

Purpose and Fit

The Night Stick NSP-4640B Forge is a helmet-mounted LED flashlight built for firefighters and industrial workers who need hands-free illumination. It clamps to any fire helmet or side-brim hard hat and the multi-angle mount lets the user aim the beam around goggles or face shields. The three output modes cover scene lighting, general work and a 30-lumen survival setting that runs for 30 hours on two CR123 lithium cells.

Runtime and Environment Limits

The highest 360-lumen mode throws a focused beam to 218 meters (715 feet) but will drain the batteries faster than the lower settings. The 180-lumen mode extends usable time while still providing strong forward light. IP-X7 waterproofing means the light survives temporary immersion, yet it does not guarantee protection against high-pressure jets or prolonged submersion beyond the rated depth and duration. Cold temperatures can also reduce lithium cell capacity, shortening actual runtime in winter conditions.

Mounting and Common Issues

The included multi-angle bracket slides onto standard helmet brims and locks with a thumbscrew; no tools are required. Users should verify that the brim thickness falls within the clamp range before relying on the mount in an emergency. Over-tightening the screw can crack the bracket or deform the helmet brim, while under-tightening lets the light shift under vibration. The CR123 cells must be inserted with correct polarity; reversed installation will prevent operation and may damage the contacts.

Questions about this item

Which lumen setting should I choose for the longest runtime?

The 30-lumen Survival Mode runs for 30 hours on two CR123 lithium batteries, giving the maximum operating time.

How far does the 360-lumen beam actually reach?

The high-output beam projects to 218 meters (715 feet), providing long-distance illumination for search or scene lighting.

What does the IP-X7 rating allow in real use?

IP-X7 means the light survives temporary immersion in water, so it keeps working in heavy rain or if dropped in shallow water.
