The Nightstick NSP-4612B Dual-Beam Headlamp is a versatile, long-runtime lighting tool that's built to last. It features a 100-lumen spot beam, 20/90-lumen white flood beam, 18-lumen red flood beam that protects night-acclimated vision, and dual white spot/flood setting for both focused distant viewing and nearby area lighting. Runtime on a fresh set of three AA batteries is 18 hours on spot, 13.5/75 hours on white flood, 37 hours on red flood, and 3.5 hours on the dual beam. The rear-mounted battery pack balances the weight of the light for comfort, whether you're using the elastic headband or the rubber hard hat strap. The lamp features a lightweight, IPX7-waterproof polymer housing that's submersible to 3.3' and rated to withstand drops from 6.6'. You can tilt the head to place the beam right where you need it.
