It would be nice if the manufacturer's website was a lot more transparent about the specifications so you could make an intelligent comparison with other lights. It is not listed on the bike headlight database
https://www.bikelightdatabase.com/headlights/ where you can compare lights side by side. Doesn't list the light dimensions, the battery capacity, average run time in each mode, and weight. As to "literally outshines car lights", this is true since an H1/9004 headlight puts out 700 lumens in low beam and 1200 lumens on high beam. So, it is brighter than a car on low beam but not on high beam. However, a simple single CREE XML-T6 flashlight run on a 18650 battery can put out 1070 lumens according to the CREE website. The idea of a replaceable Li-ion battery is a plus but I wonder why they chose the rather oddball 26650 size (19.5 x 65.4 mm) rather than the very common 18650 (18.6 x 65.2 mm) when the capacity of the two are almost the same.
