It has a daytime running light with 150 lumens, two dipped beam levels with 450 and 700 lumens and a brightness sensor that automatically activates the dipped beam in the dark. Thanks to the quick-release mounting on the handlebars, the light can be removed in seconds without tools. The housing and the quick release are made of CnC-milled and then black anodized aluminium. The built-in 12 Wh battery has a charging time of 3.5 hours and a maximum runtime of 2 hours in low beam and 16 hours in daytime running light.
The SL Mono is impact and water resistant to IK09 and IP67. As with all Lupine lamps, the housing is not glued to ensure long-term reparability and the replacement of individual parts.
