So how do you explain the several people here who have ridden
successfully with only dynamo lights for decades?

In the "way back when" days folks rode bicycles equipped with a
carbide lamp successfully. I my self rode back and forth to work, for
more then a year, on a bike with a "bottle generator" and an
incandescent light bulb.

One can only speculate how "back in the good old days" we were able to
accomplish these seemingly miraculous feats and now one must have some
sort of super light with multi giga-hoozet power.
