The reviewer compares the Sofirn BS01 bicycle light to the Lumintop B01 and Busch & Müller Core 2. He notes it's a budget light (around €30) with a replaceable standard 21700 battery, USB-C charging, and multiple brightness modes. However, he criticizes its significant brightness drop over time, non-STVZO certification, and less-than-ideal beam pattern for distance vision.
