We put a knob on it!
Dial the brightness up and down easily, and it’s named Volume – ba boom!
The knob makes a lot of sense while riding and needing to quickly and easily adjust on the fly, as opposed to the normality of current products with press-and-hold buttons to change modes.
With a replaceable battery and sustainable materials, it seems to be the simple things that make a real change.

The Volume Light comes in two different models: The Volume™ 800 has an efficient 800 lumens beam and a lightweight and durable plastic casing aimed at commuters or training rides. The Volume™ 1500 is even more powerful: With its 1500 lumens, high-capacity 4000 mAh battery, and a sturdy aluminum body; it meets the needs of the most demanding cyclists and for long rides. Both lights can also be charged while riding.
With the Volume light, Bookman also introduces USB-C charging with a replaceable battery. Great if you need a backup battery for long rides, need to replace a damaged battery, or when recycling the product at the end of its life – making it more sustainable. Bookman has also shifted their packaging away from plastics to a 100 % paper-based, sustainably sourced solution that can be unpacked and resealed without ruining the packaging.
