Much is made about different methods of measuring bicycle lights. I think the best thig is to asctually try the light in the conditions you ride in.

If I'm going to or have to test a light only AFTER BUYING it then I'll just wait until night time, ride to where I need to know how the light works for me and then simply turn on the light. Does it light up the road enough and far enough ahead for me at the speeds I ride? Yes, then I'll keep the light. No, then I'll return it for something better.

Opps. Sent too soon.

I meant to add that lights can have very similar outputs but widely varying beam shapes/road illumination and therefore widely varying usefullness. I was aastounded at just how poor the hub dynamo light I tried outside a bicycle shop on a very dark section of road actualy was. Ditto for some battery lights.

Huh. My experience was the exact opposite. I suspect we've used
different dyno-lights. I'd been a die-hard battery-light disciple for
years, and had several different models (each better than the last, as
tech improved.)

But I was persuaded to try a dyno-hub for my 2 mile suburban commute,
where light _to see by_ just wasn't needed, or hardly, and the dyno
convenience was a factor.

I so liked my B&M Luxos, I tried it on a recreational ride in the _dark_
countryside, and within a month, put another Luxos on my rando bike.

On my first long dark ride with it, I continually annoyed my riding
partner with "I really LOVE this light" - because of its useful beam
pattern. The Luxos has no more lumens than my last few LED battery
lights, (at least not on the settings I used) but it enables me to see
much better. No central "hot" spot to affect my night vision, just an
incredibly wide field of even light.

(Paired with Shutter Precision dyno-hubs).
