Beam Comparison - Bike Light


Battery Life vs. Beam Distance - the above graph shows how beam distance at the brightest setting degrades as battery life runs down. We use the ANSI FL-1 battery run-time spec, which says run-time for the high mode is finished when brightness degrades 90% from its initial value.

                                       Cygolite Metro 360: we measured the maximum beam distance as 135 meters and the ANSI battery run time for the high setting as 2.1 hours.
                                       NiteRider Pro 1800: we measured the maximum beam distance as 172 meters and the ANSI battery run time for the high setting as 4.9 hours.
