This standard was created by the American National Standards Institute (ANSI) to provide consistent performance measurements for handheld lights. Although bicycle lights are not required to follow this or any standard, Blackburn believes in offering full transparency in how the output, run time, water resistance and other performance claims are measured.
LED Fuel Gauge/Charge Indicator
A small built in LED light indicates the battery level. Green = >75%, Orange = 75-25%, Red = <25%
Universal Light Mount
The silicone mount fits diameters from 15-35mm along with a clip for clothing, bags or racks.
