For example, its 2000-lumen output can illuminate a path up to 277 meters, ensuring safe visibility on unlit roads or trails. With a built-in 21700 battery, USB-C charging, and a powerbank feature, it offers practical functionality. Featuring a 1-year warranty, this Sofirn BS01 for Outdoor Use suits cyclists and outdoor enthusiasts.
Powerful Illumination for Outdoor Use
The Sofirn BS01 features high-efficiency LEDs with a color temperature of 6000-6500K, delivering a maximum output of 2000 lumens with a beam throw of 277 meters, powered by a built-in 21700 Li-ion battery (5000mAh). It offers six modes, controlled by a single button switch, with the following lumen outputs and runtimes:
- Turbo: 2000 lumens for approximately 1 hour (throttles down after a few minutes)
- High: 400 lumens for approximately 3 hours
- Medium: 200 lumens for approximately 6 hours
- Low: 100 lumens for approximately 12 hours
- Strobe: 2000 lumens (runtime not specified)
- SOS: 2000 lumens (runtime not specified)
The light charges via a built-in USB-C port in about 2.5 hours, with a battery indicator (green for 50-100%, red for 25-50%, flashing red for under 25%). It is IP68 waterproof (submersible to 2m) and includes a smart mode that turns off after 30 seconds of no movement, though the lack of a lock mode may lead to accidental activation, requiring careful storage. This makes the BS01 a versatile choice for outdoor use, though users should manage heat and ensure proper mounting.
Durable and Compact Design
The Sofirn BS01 is constructed from A6061-T6 aluminum alloy with a durable finish, offering reliability for rugged cycling conditions. It measures 32mm x 30mm x 112.8mm, weighing approximately 200g with the built-in battery, making it sturdy for bike mounting. The light features a Garmin-compatible mounting system (also fits Wahoo frames), a rubber button with an LED indicator, and a sleek design, though its size may require a secure mount to prevent wobbling during rides. This makes the BS01 a durable, compact choice for outdoor use, though users should ensure a stable mount.
Designed for Outdoor and Cycling Use
The Sofirn BS01 2000 Lumen 277m Throw Rechargeable Bike Light with 21700 Battery and Powerbank for Outdoor Use is tailored for cyclists and outdoor enthusiasts needing a reliable, smart light for night riding, commuting, or emergencies. For example, its 277m throw ensures visibility on dark trails, while the powerbank function can charge a phone during long rides, though the step-down from Turbo after a few minutes limits sustained high output, and the smart mode may turn off unexpectedly if the bike stops, requiring manual override. The IP68 rating, USB-C charging, and motion detection enhance its utility, but users should avoid direct eye exposure due to its intensity. The BS01's affordable price, included battery, and powerbank feature make it a practical choice for outdoor scenarios, offering a balance of power and convenience, though users should plan for mode adjustments and mounting stability.
