8000mAh 5 Led Bike Light Front Waterproof Led Flashlight for Bicycle Rechargeable 5200Lm Headlight Lamp Bicycle Accessories

I have 3 versions of this light;

I use the 2400 lumen, 4000mah 3 LED version on my gravel bike. Its worked great for 6+ months. Doesn't last long enough for running 3-4 hours but I only use it to light up the night for a couple hours at a time and use tiny but silly bright drone blinky lights for my "being seen" marker lights. It lights up enough for road and gravel rides in pitch black for sure.

I've been using the 5200 lumen, 8000mah 5 LED light on my mountain bike for 6-8 months as well. I do night rides about once a month on it and its lasted 2-3 hours on high. It is crazy bright and I have yet to encounter someone with more light on their bike for under $150. It makes the 1000 lumen headlamp I use pointless in all but the most vertical or fastest places where you can utilize the head lamp pointed high too see around turns/hills.

I just received the 6000 lumen, 10,000mah 16 LED light. I haven't compared it anywhere except the garage, hoping to get out early this coming weekend and compare it on the trail with my buddies who also has the 5200 Lumen.

I've used the supplied powerbank feature on all of them just in testing to see if they'll charge my phone or my computer and they do. But, I don't see myself needing such a feature very often.
