There are no laws restricting maximum brightness.
StVZO only requires that when the middle of the beam is aimed to reach half the mounting height 5 meters from the bike, at 10 meters 3.4 degrees above the brightest spot must not measure over 2.0 lux.
E-code HID projection headlamps in cars are astonishingly bright in spite of a being allowed only 1.0 lux at that inclination and 25 meters.
I've tried some German lights, and though the beam pattern is nice, they're not bright enough for my rides.
Which ones? Newer ones with better reflectors put twice the light on the road with longer run times.
