BOOKMAN

Mounted on a GoPro mount and works great. Easy to adjust strength with the wheel. Using it for a gravel bike.

If a company can turn an unsatisfied customer (due to a defect in the lamp mounting in the previous version) into a satisfied customer, then that is a big deal, because not every company can do that. Thank you for the very positive resolution of the complaint - currently the lamp is holding well on the mounting and I hope it will work and please for a long time 🙂

Great light, really like the replaceable batteries for longer rides and how easy it is to change the modes. Wish it came in more colors

Best bike light.
The brightness is excellent and the Akku endurance is also excellent.

Volume 1500 fulfilled all my expectations of a high-end premium light. Great functions and beautiful design!

Just bought the 10 pack for my bike and they are so awesome. It was enough to cover my whole bike and a lot of people mentioned how cool they look. Would totally recommend BOOKMAN and I’m going to shop some other reflective things for my bike soon!

Very practical lamp with intensity control via the selector rather than a button, I love it!
What's more, on long runs it's difficult to recharge the lights, so the fact that you can change the battery directly is really great - almost no other brand offers this and it's a real bonus!
The brackets supplied are practical and high quality!
Thank you for this great product!

I've used couple of lights already and I have dyno lights too but Bookman changed everything. Powerfull device in awesome design.

The Volume 1500 works well in situations requiring warm winter gloves, whether for road, gravel or MTB, because it is so easy to control the brightness. Important, because to maximise battery life, it is best to switch to lower lumen levels when possible. On a full charge I could just about ride all night. I find the full 1500 lumen brightness is seldom necessary unless road cycling at speed. The 750 lumens setting is my go-to level of brightness and the stated 5 hours is about right.
I compared the light with a range of other bike lights and it beat the competiton at the 350 lumens setting. At this level I found I was still able to ride gravel and mtb in pitch black on narrow single tracks.
In terms of feel, build quality, and packaging, in my experience it does not get any better.
Mounting: On my MTB with a thick bar (30mm diameter) it fitted easily and quickly. Fixing the mount to my gravel bike handlebars did take me more than 10 minutes. Once mounted I liked the way you could move the light horizontally a few degrees from centre - R or L.
Battery charging: The light arrived at my house with two bars of battery life illuminated. So, I decided to run the battery right down and then I did a full battery charge, taking just over nine hours. What I didn't like is the fact that the battery will suddenly die at a particular setting when out of juice. I have to check the 4 battery charge levels and as soon as they get to only two I turn the light down a notch.

Just a quick update. I've been very happy with the battery duration and the easy to manage. The looseness was solved after tithing up the bolt inside the Garmin like lock.

JUST, if you have a Tarmac SL8 and a EXS Handlebar it won't fit. Not sure with other integrated cockpits, but the Roval should be fine as the computer mount lies in front of the cockpit. But if your integrated cockpit haves the mounting bolts underneath and you have a Tarmac SL8 it won't fit because of the speed sniffer.

Not tested to its fullest as yet as I haven’t ridden in the dark.
Have been using on flash mode for a few hours whilst riding and the battery is still full!

I’ll be testing to capacity later in the year with a 14 hour ride.

Really solid construction

This is the best bike light I have ever had! It is super strong, stable and very cool! The turning knob is a smart way to change brightness easy on the go. I absolutely love the bright orange color.

Good light when compared to others I have! Sturdy material, nice design and sufficient functions. Battery life goes beyond advertised.

Great cross belt, wide straps, dresses very well :) good buy for night adventures

I have been using it for Gravel/road rides the last 3 months now and I fully agree with all previous 5 star comments.
