The LED Lenser LED6107 SEO7R rechargeable Headlamp featuring Opti-Sense™ Technology is truly stunning. Cutting-edge technology and a contemporary fresh design combine effortlessly in this high-end German engineered Headlamp that raises the bar in performance hands-free lighting. The SEO7R incorporates one CREE® Power LED premium light chip that delivers an impressive 220 lumens from its rechargeable Li-ion battery pack (included). The micro-chip controlled Smart Light Technology™ enables two energy usage modes plus Power, Dim (100%-15%) or Signal light options to be selected and the patented Advanced Focus System™ optics provide the option of either flood beam (near illumination) or a sharply focused spot beam (distance illumination). The clever Opti-Sense™ Technology senses the amount of light required and automatically adjusts the light output. This function can be de-activated if desired. For directional lighting the lamp head swivels within an angle of 90 degrees and a very handy transport lock is integrated to prevent the Headlamp accidentally switching on, unnecessarily draining the batteries. The adjustable, anti-allergic, washable and replaceable headband combines with the precisely weighted lamp to add a level of comfort that is the icing on the cake of this exceptional lighting instrument by LED Lenser.
