Skullerz 8981 Hard Hat Headlamp easily attaches directly to any Ergodyne Skullerz Hard Hat or Safety Helmet light mount. Simply slide and clip the LED light into the front or rear built-in mounts for a secure fit. Headlamp also includes a built-in magnet on the back of the mount to attach the light anywhere metal or to use as storage when not on the hard hat. LED light features a four-position tilt-head design and one-button switch that supports two working modes: spotlight and floodlight. Spotlight (150 lumens) is for tight-beam, long-distance visibility. Floodlight (50 lumens) is for a wider, close-area visibility. Light lasts up to 6 hours in spotlight mode and up to 10 hours in floodlight mode. Headlamp requires three AAA batteries and is rated for IP54 protection. The light can be easily detached from the built-in mounting bracket to change batteries or use as flashlight.
