I like good lights and don't like when bike light beam is designed as flashlight. I understand that lights for mountain bikes and road bikes serve different purpose and I think lights need to be marketed as such. I also like StVZO certified lights not only because they don't blind incoming traffic and pedestrians but also because they put all light where it's needed for the road bike. I spent quite some time searching for a good light for my Brompton. With all above in mind it wasn't easy. STVZO certified lights are mainly available in Germany and are mostly not available for delivery to Turkey. I checked other options form the like of Kreptonine and StVZO certified cat eye models (yes they also exist) but couldn't find perfect option.
Monsters from Lupine and Supernova were insanely expensive with pretty big battery packs that I wasn't sure would fit my Brompton.
And then I came across Outbound Lighting in one of the forums. While it's not StVZO certified, it's designed by the same principle with light cutoff and wide spread. So I decided to give it a try as it also looked like battery pack is not too big and could fit under the frame.
Well, it just came in! While I'm yet to make pictures outside of the beam pattern I'm very happy to say that it fits my Brompton. And it fits perfectly! Gopro mount design by outbound lightening is very smart and ensures low profile while mounted with huge gap between the bag mounted on the front carrier block! Looks slick too. I figured best place for battery will be under the front portion of the frame but will need to see how it will fold this way and if cable will rub it too much.
Beam pattern to the wall:
Even though I took my phone camera to manual exposure which didn't change its still not possible to make picture exactly the same as what human eye sees. You see more light than on these pictures but it would give an impression of beam pattern on the ground. Beam pattern would probably be better if the light would've been mounted on the handlebar. Min and Max settings:
Light on TRIGO bracket using gopro friction mount adaptor on the light:
With mounted battery:
Bike folds with this setup just fine.
