Klein® rechargeable hard hat headlamp easily attaches directly to a Klein® hard hat or Klein® bracketed strap. When you need a stationary work light, simply mount the headlamp onto any ferrous surface with the convenient integrated magnet. This versatile light provides three light modes to fit your task - floodlight, spotlight and ultra-bright boost mode. You'll know when it's time to recharge the lamp, because the LED lights on the battery gauge clearly indicate how much battery you have left.
