Review on TANSOREN USB Rechargeable Bicycle Light Set: 2000 Lumens Front and Back LED Lamp for Road Cycling - Waterproof, 5 Light Modes by Jeb Moorehead

At low speed, best for city driving. Light hair for courtesy light. Has a very good running time. So far there are no problems. Haven't been in the rain yet. More than I expected. And harder. Which is understandable given the size of the battery and long runtime. Put it on my mountain bike instead of my gravel bike. The gravel bike was the intention. Looks better on a mountain bike. good light. The quality looks good. If it gets better or worse over time (I've used it less than 6 hours so far) I'll definitely update it. UPDATE: The base is broken. On the 1st bumpy trail I took it. It broke at the hinge. The light has actually gone out. Made it through a rocky area by vibrating the pedal. Now my excellent bicycle light has become just a flashlight that I no longer need any other. Base combined with light weight is a bad combination. The high weight of the lanterns is ok. Top quality light. The base is complete junk. 1 star because I now have to buy a different bike light.
