With a light range of around 70 metres and 60 lux, the Aura 60 USB illuminates roads and paths evenly and provides improved lateral visibility with the "Light Guide". This not only increases road safety, but makes the StVZO light a top quality companion especially for sporty riders and commuters. 3 modes from 60 lux in Standard mode to 30 lux in Mid mode to 18 lux in Eco-mode, bring optimal light both in the city and off the road. By choosing the appropriate mode, the burn time can be extended from 4 to up to 10 hours. The AURA 60 USB is therefore suitable for demanding cyclists (for example commuters and athletes). Also suitable for safety conscious leisure cyclists. Weighing only 105 grams, the Aura 60 USB is hardly heavy and impresses with its unique construction for all cyclists who pay attention to design and weight. Its flat, sleek and slightly conical body as well as the side "Light Guide" round off the sporty appearance. The AURA 60 USB has a built-in lithium-ion battery. This is charged via the micro USB socket, which is also possible via any PC. With the included micro USB cable, the battery is fully charged and functional in a maximum of 3.5 hours. The lithium-ion battery has a deep discharge and overcharge protection. In addition, it has no memory effect and can easily be fully charged. The side "Light Guide" is not only an optical highlight, but thanks to the two additional LEDs also provides a significantly higher visibility in road traffic. Illumination intensity (LUX): 60.
