Meets ANSI FL-1 Standard: 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.
