The rechargeable AURA 45 USB illuminates 45 meters at a distance of 55 meters, making it ideal for safety-conscious everyday cyclists who also regularly organize their leisure time activities by bicycle. A new feature is the integrated brightness sensor, which automatically regulates the illuminance and thus enables the optimum ratio of luminosity and lighting duration.
In standard mode, the AURA 45 USB illuminates at 45 lux for approximately 6.5 hours; in e-mode with 15 lux it brings a total of 21 hours of illumination. In addition, it has the auto mode with automatic brightness adjustment.
Automatic light adjustment
The AURA 45 USB is the first SIGMA bike light that thinks! In the "Auto" lighting mode, an integrated brightness sensor automatically adjusts the illuminance to the ambient light. This ensures the longest possible lighting time.
Multiple zone illumination
With a homogeneous light image, the AURA 45 USB provides optimal visibility in the long-distance, side, core and close-up, without dazzling other road users. This ensures maximum safety on the road.
In auto mode, the built-in brightness sensor automatically adjusts the illuminance to the ambient light within a range of 15 to 45 lux.
Wide lateral lighting elements on both sides provide improved visibility of the bicycle light in traffic.
The AURA 45 USB has a built-in battery. This is recharged via the micro USB socket, which is also possible on any PC. With the enclosed Micro-USB cable, the front light is fully charged in just over 2 hours. The lithium-ion battery has a deep discharge and overcharge protection. Furthermore, it has no memory effect and can easily be fully recharged.
Battery and charge indicator
The charge indicator on the control knob tells you what state the battery is in. Under 70 percent of the battery capacity, the LED in the button glows green, below 30 percent red. Also during the charging process, it informs you about the current state of charge. As soon as the battery is full, it lights up green. You can also charge the AURA 45 USB during operation. B. on the way with a power bank.
With a double-click, the bicycle light is switched on, with a long press of the button again. This function prevents unwanted switching on, eg. B. in the bag.
The AURA 45 USB is protected against splash water according to the international IPX4 standard and therefore also suitable for bad weather conditions.
The practical silicone handlebar mount is firmly attached to the AURA 45 USB and guarantees fast and precise attachment to any bicycle handlebar. This allows the bicycle light to be mounted and removed without tools. In addition, the AURA 45 USB is also compatible with other SIGMA holder systems, such as the screw bracket and the universal helmet mount.
The AURA 45 USB is equipped with an Osram LED. In combination with the high-performance optics, this creates a very uniform light distribution across all light zones.
