The B&M beam is a trapezoid, and I can aim it so there is no wasted light anywhere. That's why 200 lumens (my estimate) suffices for me. It's not enough for some people, but it's more useful than some higher power lights because of the shape of the beam.
If you ride enough to be picky, then be picky! Your emphasis on light
distribution instead of light
output is refreshing. There is a reason some car people (myself included) still insist on Cibie headlights instead of million-lumen Bloo Blinderz HID junk from the fleabay. Seeing is critical; blinding other people is dangerous, arrogant, and counterproductive.
I am not serious enough yet to spend up for a B&M, but I definitely do want an automotive-style low beam cutoff. I think I'm going to try the Ravemen PR900. The combination of both low and high beams, with different light distribution, makes more sense to me than adjustable brightness does.
