With a light output of 50 Lux, the X&O 50 is at the top of the X&O range. The X&O 50's efficient Reverse Beam Technology (RBT©) produces a powerful light beam. This allows you to see up to 70 meters and be seen from a distance of 4000 meters. The automatic daytime running light function provides a light beam during the day that ensures you are seen and provides visibility throughout the day, with a new high beam function that can be activated with an ergonomic separate handlebar switch. This switch produces a more intense, wider, and brighter light beam of 50 Lux on top of the normal 50 Lux light beam. This results in a total light output of 50 Lux + 50 Lux.
