The Acebeam BK10 LED bike light delivers up to 2,000 lumens for clear road and trail lighting. Its STVZO-style rectangular beam aims light at the road while reducing glare for people ahead. An optical PMMA lens gives a broad, even beam with an 85-degree spread.
First, choose one of five light levels to suit the route. Turbo reaches 2,000 lumens, while the 30-lumen ultra-low mode can run for up to 37 hours. The light also has an SOS mode for an emergency signal. A single switch controls every setting.

Beam design and run time
The BK10 uses a 21700 5100mAh cell. Therefore, it combines high output with useful run times across the lower modes. High gives 1,050 lumens for up to 1 hour 45 minutes. Medium gives 350 lumens for 6 hours, while low gives 150 lumens for up to 15 hours 45 minutes.
Also, the aluminium body has a hard anodised finish and a removable rubber pad for shock control. Smart heat control adjusts the output when needed. Finally, mount the Acebeam BK10 LED bike light firmly, aim it below eye level and test every mode before riding. Charge it in a dry place and follow local bicycle-light rules.
