[AT] OT LED question

Sun Nov 6 04:00:44 PST 2016

Cecil, there's a really interesting little detail buried in your comment.
In short, beware of any LED bulb if you find one claiming to retrofit into
old automotive reflectors designed for incandescent.

I've done some reflector design, and it all begins at the light source (the
filament with incan, or the emitter surface with LED) and from there it's
just geometry, bouncing photons, like you're playing billiards.  A TINY
change in the light source and you miss the shot, so to speak.  LED emitter
surfaces look absolutely nothing at all like a filament.

SO
