The yalumi Spark headlamp utilizes a sophisticated optical lens for a superior beam pattern and higher light efficiency. Three AAA batteries (included) power one Cree XP-E high-output white LED light for long-distance illumination. It provides a narrow, focused beam of 105 lumens in maximum mode and throws light up to a long distance of 90 meters. The maximum burn time is 187 hours in economic mode and 95 hours on maximum mode (burn time may vary based on battery brand and life). The exceptional lens qualities in the yalumi Spark are rooted in more than 16 years of experience in engineering state-of-the-art solutions for camera lenses, video lenses, scanners, and other optical products. The adjustable headband with lamp-angle tilt allows aiming of the beam. Lock mode keeps you from accidentally enabling the light--and draining the batteries--when the headlamp is stored in your pack or pocket. The headlamp also is IPX4-rated for water resistance. With a compact and lightweight design, the Yalumi Spark LED headlamp is ideal for outdoor activities or for technical activities where bright, precision-focused lighting is a requirement.
