Sigma Buster 1100/Buster RL 150 (SD19870)

The front and rear bike light set by Sigma is a solution positioned between the mid-range and advanced price segments. The manufacturer recommends these accessories for purchase by quite demanding cyclists, including fans of road racing, long trips, brevets, etc. The front light of the Sigma Buster 1100/Buster RL 150 set is notable for having two quality Osram LEDs. These provide a high luminous flux of up to 1100 lm and good lighting range of 165 meters.

Users are offered 6 different modes, including 4 brightness settings (starting from 150 lm) and two flashing options—more intense daytime and nighttime. The battery life ranges from 2 to 16 hours with constant lighting and from 5 to 50 hours with flashes. The Buster RL 150 rear light has two LEDs, provides brightness up to 150 lm, and visibility up to 2 km. Besides its 5 operating modes (2 types of constant light and 3 flashes), it supports a brake light function: a special acceleration sensor automatically activates the model for 3 seconds when braking. The useful features of the accessory set include the memory function for the last set configurations, a protective lock against accidental activation, informative charge level indicators (the front light also has a mode display), USB C port power, and all-weather design (confirmed by IPX4 water resistance rating).
