BOOKMAN is a lighting brand started by two friends in Stockholm, Sweden.
Drawing on their nation's deep-rooted culture of prioritizing safety, combining it with minimalist and functional Scandinavian design, and incorporating innovative technology, they sell lights, reflectors, and more designed for cyclists, runners, and pedestrians.
With their unique forms and colorful variations, these items have been attracting attention, especially among design-conscious users, and we have begun carrying them at Circles starting this spring.
Today, we would like to introduce three items from BOOKMAN!
Block Light


The Block Light is as cute as it is compact. Measuring just 2.2cm W x 3.2cm H x 1.3cm D, it is incredibly small and can be easily attached to a bicycle using a rubber band.

Honestly, I initially wondered, "Can such a tiny light really illuminate the road properly? And I'm worried about the battery life..." But when I actually turned it on in the dark, I was shocked—"It's so bright... wait, this is amazing!" (laughs)
The secret to its brightness lies in its slim lens, which disperses the light. I was surprised at how much difference a lens could make, even with a maximum output of 50 lumens.
Additionally, it features the latest LED and lithium-ion battery technology, allowing it to run for up to 25 hours.
This light is perfect for smaller children's bikes, or for those who feel that large lights are too conspicuous and detract from the look of their bike!

BOOKMAN Block Light (Front/Rear)
Dimensions: W2.2 x H3.2 x D1.3 cm
Light modes: Flash, Strobe, Steady

Battery: Rechargeable lithium-ion battery

Volume 800

Have you ever had the experience of entering a tunnel while riding or finding that it's gotten dark out, only to realize the power button on your light is so small that you can't easily press it?
The Volume 800 solves that annoyance.

With a large power button and a dial on the side, you can adjust the brightness just like turning the volume knob on a stereo.





The brightness can be adjusted across five levels, and you can switch between flash and steady light with a simple tap of the top button. With a maximum of 800 lumens, it illuminates the path ahead even on roads with few streetlights.
Additionally, the oval-shaped beam eliminates dark spots, and the cap edge ensures that oncoming traffic is not blinded.
