With 2000 lumen the 500 setting is good. Each LED has it's own reflector. Might not have enough cutoff, as it does light up signs a bit... but just point it down a little. 6 hours at 500 is good run time. And can be put on different bikes easily. Light can be taken off and used as a flashlight.
TAZ 2000 216 grams, $240.
SON Hub and Edelux light 450 grams, $400, plus new rim and spokes....add another $150, plus labor to build the wheel.
Take you pick Fietsbob... what's the problem
L&M is not junkie china stuff.
Don't tell me the SON hub has resistance when turning the axle, but it's not perceivable....that's BS.
