No USB-C cable in box. The constant mode goes from 100? to 200? to flash? The flash modes work fine. Overall a nice light but something feels off with operation and packaging.

I use it for my Nanrobot D6 + electric scooter, in the community. It lights up very well.

I was not expecting such a high-quality light for the amount that I paid for this thing. So far I have not been disappointed by anything I have bought from O Light. Well done!

Purchased two both working great. The price is excellent. I did manage to break one of the retention straps on the mount on some single track but it was a pretty decent hit on a big rock and light was fine. I would rather have a strap break anyway. so far I have around 500 miles of riding in total on lights pretty ruff terrain.
