Designed for working people, the Nightstick NSP-4608BC Clip-On LED Headlamp comes with a stainless steel clip that attaches to an adhesive-backed hard hat bracket, for hands-free light on the job site. You have the choice of a 180/100-lumen spot beam, a 140/80-lumen flood beam, or a 220/115-lumen dual beam, providing illumination far off, nearby, or both. 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. Runtime on a fresh set of three AAA batteries is 5/14 hours spot, 5/14 hours flood, and 4/7 hours dual beam.
