Headlight illumination — 35 lux.

The Sigma bicycle light is a rechargeable accessory in the mid-price range. The model is suitable for daily use and bike rides, featuring a brightness sensor and fully automatic operation mode: the light output adjusts between 15 to 45 lux depending on the current ambient light. Additionally, users have access to two other modes: eco and standard (maximum brightness). The lighting range reaches up to 55 meters, which is generally sufficient for leisurely, not too fast cycling.

The Sigma Aura 45 light is powered by a rechargeable battery, which can be charged via a micro USB port (full cycle from 0 to 100% takes 2.3 hours), has an indicator of the current charge level, and should provide from 6.5 to 21 hours of autonomous operation. Other features of the model include the plastic housing's resistance to adverse weather conditions (claimed to meet IPX4 standard), activation with a double click to prevent accidental activation, compact size (housing length up to 9 cm), lightweight (88 grams), and easy tool-free mounting with the included flexible strap.
