The AURA 45 USB bicycle light from SIGMA SPORT is characterised by a full 45 lux and a harmonious light image up to a distance of around 55 metres. Safety-conscious cyclists are delighted with the integrated brightness sensor, which automatically regulates the illuminance. This ensures the longest possible lighting duration. This makes the bicycle lamp ideal for city cyclists who are sometimes off the beaten track.
In the "Auto" lighting mode, an integrated brightness sensor automatically adjusts the illuminance to the ambient light. The Auto mode is indicated by the yellow indicator light. In addition, the AURA 45 USB has the standard mode with 45 lux and 6.5 hours light duration as well as the Eco mode with 15 lux and 21 hours light duration.
StVZO bicycle lighting in a set
SIGMA offers bike safety at a fair price: The AURA 45 USB front light is available as a set with the NUGGET II tail light. Together they ensure good visibility all round.
The AURA 45 USB has an integrated rechargeable battery. This is recharged via the Micro-USB socket, which is also possible on any PC. With the included Micro-USB cable, the front light is fully charged again in a maximum of 2.8 hours. The lithium-ion battery has a deep discharge and overcharge protection. Furthermore, it has no memory effect and can easily be fully recharged.
Wide side lighting elements provide improved visibility of the bicycle light in road traffic.
Homogeneous light image
The AURA 45 USB is equipped with an Osram LED. In combination with the high-performance optics, this produces very uniform light distribution and ensures optimum illumination across all light zones.
The AURA 45 USB can be switched on by double-clicking on it, and then switched off again with a long keystroke. This function prevents unintentional switching on, e.g. in the pocket.
The practical silicone handlebar holder is firmly attached to the AURA 45 USB and guarantees quick and precise attachment to any bicycle handlebar. This allows the bicycle light to be mounted and removed without tools. The AURA 45 USB is also compatible with other SIGMA mounting systems, such as the Screw Bracket and the Universal Helmet Mount.
