This hard hat light easily attaches directly to any Skullerz® Hard Hat or Safety Helmet light mount. It simply slides and clips into the front or rear built-in mounts without the need for clunky straps or clamps. This portable headlamp features a built-in magnet on the back for securely attaching the light to metal on the worksite or for storing when not attached to a hard hat or helmet. Simply detach from the built-in mounting bracket to use as a flashlight/work light or to change batteries. It features a five-position tilt design for visibility where you need it. A one-button switch supports two working modes: spotlight and floodlight. Spotlight (150 lumens for 6 hours) is for tight-beam long distance visibility and floodlight (50 lumens for 10 hours) is for wider close area visibility. Requires 3 AAA batteries (not included).Note: This is a non-returnable item.
