I'm quite happy w/ my old-school generator + Union headlight,
supplemented a little with flashlight battery lights.
It is enough. A lead/acid ***cycle battery would
be overkill in terms of power o/p, let alone environmental
concerns when the damned thing is ready to be discarded.
The venerable Union headlight still works well because of
its intelligently designed Fresnel(ish) lens + reflector,
and the broad disc of light it emits.
New technology isn't always better technology. A lot
of times, predecessors have already figured things out
for us, that continue to work quite well. In that vein,
I guess posterity needs us contemporaries to figure out
how to make LEDs work best for 'em -- if indeed It Is
Written that posterity will only have LEDs at their avail.
Frankly, when riding at night, I don't even want to
turn night into day. That's not what bicycles are for.
Adaptation requires artfulness & finesse, not the
Brute Force & Ignorance impinged by the ongoing quest
for "better/stronger/brighter," and for technologies
that do our brainwork for us.
Nothing is safe from me.
