With up to 1000 lumens of hands-free light and the ability to choose spot or flood beams, the RucPac Professional Focus Headlamp is a versatile lighting tool suited to a wide range of uses, at work and at home. The light offers high, medium, low, and flash settings, all controlled by a large rubberized push-button switch that's easy to operate even when wearing gloves. Four AA batteries will power the light for 6-24 hours, depending on brightness levels used. The rear-mounted battery pack and overhead strap distribute the weight of the lamp for balance and comfort. The lens tilts to direct light right where you need it.
