Mtbr Light Meter Measurements
This light measured 153 Lux on our ambient light measurement facility. The light output measurement is performed by placing a Lux light meter beside the light. Both are pointed at the ceiling (five feet above) of a dark room. This measurement uses the ambient light produced by the bike light.
Integrating Sphere Measured Lumens
This light measured 1477 Lumens in an integrating sphere. Claimed Lumens by the manufacturer is 2100 Lumens. The Lumen-hour graph below shows how the light performs over the first three minutes of its battery cycle.
Tunnel Beam Pattern Photo
The location is useful since it has walls and a ceiling that can display a bike light beam pattern. The walls have a lot of graffiti on them and actually show detail when they are lit up by a light with a wide angle. Cones and targets are set up with the far target set up at 120 feet.
