LED LENSER lights are measured in lumens. LED LENSER uses ANSI/FL1 standards as published by the National Electrical Manufacturers Association (NEMA). To date, this is the only industry-wide, agreed-upon standard of measurement.
ADVANCED FOCUS SYSTEM™
Traditionally, light-focusing systems have consisted of either a lens, or a reflector. The Advanced Focus System (AFS) is the patented combination of a reflector AND lens to create a light system that provides both a focused beam for long-distance and a homogenous spill-beam for up-close reading. AFS means whether you’re reading a map up close or focusing down the path to a landmark in the distance, your light will be easy on the eyes, clear and bright.
With our Speed Focus system you can go from reading to searching by using the thumb on your holding hand to simply slide the bezel away from you. With one hand and one movement, you can achieve seamless transition from close to far and all points in between.
BLUE MOON FOCUS SYSTEM
Thanks to their special prismatic structure, our lenses separate parts of the blue spectrum from the white spectrum. The blue components are thus projected to the edge of the light cone and the result is an excellent, clean white light to read by with a mellow blue circle to frame the reading area. Blue Moon optics make reading and general viewing easy on the eyes for less eye fatigue.
