Review on 🚴 Cygolite Hotshot SL– 50 Lumen Bike Tail Light– 6 Night & Daytime Modes– User-Adjustable Flash Rate– Compact Design– IP64 Water Resistant– Durable Secure Mount– USB Rechargeable– Ideal for High-Traffic Roads by Tony Guernsey

I like the brightness of the light, but the load on my light is much less than the description "working time of 230 to 200 hours". The first charge seemed to last a while, but after that I only had 4 or 5 rides on a single charge. It turns out about 10 hours. Maybe it's normal, but it seems bad to me. Cygolite agreed so I sent the flashlight back to them and they "replaced" it under warranty. Unfortunately, the new flashlight only offers 11 hours of use on a single charge, suspiciously the same as the flashlight I returned. I would not recommend this light
