For the see-by front lights, it's a big spectrum but we generally start with urban lights with an output around 400 lumen, road lights starting around 700 lumen, gravel or off-road riding starting around 1,000 lumen and MTB lights are usually 1,400+ lumen

    Crazy to me, back in my day 450 for mtb was standard and 900 was a lot!

    The lens/reflector is just as important, but leds tend to trade lens design for more leds and more lumens. The fall off is much worse than focused lights, but they light up reflective paint amd signs really well, so people think they are working better.

    See blinding headlights on cars.

    I prefer a Sofirn Q8 Plus - it's half a kilogram so it takes a lot of duct tape to secure it to the bars, but the 16000 lumens are worth it. Car cuts you off? Double click to just vaporize them.

    Somewhere in the range of a 25 billion lumen strobe.

    Seriously though, sometimes it seems like we're invisible. Got run over a couple of years ago and I'm still salty about it.

    Cyclists are split between "why bother have a light at all" and "high-power headlamp that blinds oncoming traffic".

    Use the flashing setting. It halves the battery usage and doubles your visibility

    Up front, I usually use a flashing light during the day and a steady one at night.

    Cars can't see a steady light. I've had one pull out in front of me and i was right there.

    Cars see movement/change, and flashing lights are therefore more visible. Ideally irritating too so they stop and think 'what the fuck is that annoying flashing light'.

    Rapidly turning your handlebars to sweep the light around when you approach intersections helps too

    Either 69 lumens or 420 lumens

    The answer is you need two lights. Trail riding and having a light suddenly fail is not fun.
