Rubber-armored, drop-tested to 9.8', with flicker-free light at a comfortable 90 CRI, the LEDLENSER H7R Work Rechargeable LED Headlamp is a powerful and versatile lighting tool for professionals (but you'll probably find yourself using it around the house, too.) Its high power output is 600 lumens, but you can boost that to 1000 with a touch of the button, and the lamp's wheel switch provides dimming capability, so you can dial in just the right brightness level. Maximum runtime is an impressive 45 hours on the low (15 lumens) power setting. The H7R Work's aluminum and polycarbonate housing is IP67 waterproof and dustproof, with rubber armoring and a plastic lens cover for further protection from the rigors of the workday. Recharging the 4800mAh Li-ion battery is as easy as snapping on the magnetic charge cable. LEDLENSER's Advanced Focus makes it easy to change from flood beam to spot beam and back, while the lamp itself tilts steplessly 130° so you can shine the light right where you need it. The overhead strap distributes the weight of the lamp for comfort and support.
