I don't think it's anything fancy. It didn't list the lumens (usually means it's nothing to brag about), but I think it's much lower than 1,200. But from the testimonial videos, it looked much brighter than what I had.
The battery is smaller, like 2,000mAh, but should be good for 5 one-hour bike rides before it needs charging. The rear light should be roughly twice that. That battery readout is pretty low tech, supposedly just flashes red when it gets low.
But I bought it because it was cheap ($19) and had decent reviews. Most of the riding I do is somewhat lit, but there are quite a few sections where there aren't any street lights. This is also so that people can see me as well. There's a lot of old farts in Florida, so I want to make sure these people can see me riding down the road.
I had a dude yell at me for riding in the bike lane going against the flow of traffic. The lanes are marked with arrows going with the flow of traffic. I like to see people coming so that I can tell if they're drifting towards me or not.
