Bike light how many lumens?

A bike Light can have varying levels of lumens, which determines the brightness of the Light. Higher lumens generally mean a brighter Light, making it easier for you to see and be seen while riding your bike. The number of lumens you need for your bike Light depends on where and how you will be riding. For urban or well-lit areas, a Light with around 100 to 300 lumens may be sufficient. However, if you frequently ride in areas with poor lighting or off-road trails, you might want to consider a bike Light with 500 lumens or more to ensure optimal visibility and safety.
