Review on 🚴 Unleash Superior Visibility with 6400mAh Rechargeable Bike Lights Set - 1200lm Super Bright Headlight & Taillight for All Bikes: Hybrid, Road, MTB - Easy Installation! by Jason Connolly

I love these lights! I can confirm that the headlight emits 1200 lumens at 2ft when measured by a titanium disc. It's so bright you'll never be able to use it on high settings. I haven't measured the performance of the rear light yet. Suffice it to say that it is bright enough. And a surprise - if you press and hold the button briefly, it turns off, and the next time you press it to turn it on, it remembers your settings (flash, steady, etc.) I haven't tested charge/discharge values for yet every light. I will update this if and when I do.
