Safe for use in hazardous environments, the red XPP-5418RX-K01 Intrinsically Safe Helmet-Mounted Flashlight from Nightstick mounts on either side of a firefighter helmet or hard hat in a way that provides clearance for face shields, goggles, or other equipment. The light is CE, cETLus, ATEX, and IECEX certified and meets NFPA 1971-8.6 (2013) standards. A tailcap push-button switch activates its 200-lumen beam on a momentary or constant-on basis, and the light will run for up to 10.5 hours on three AA batteries.
