Is it possible to control LED brightness with a linear regulator? I am surprised to hear it - when I was making light effects with LEDs years ago, I understood PWM to be the only practical mechanism, due to the strongly non-linear conductivity curve.
But maybe it's possible, if you just want to fix your LEDs at a specific brightness which never changes, that you could find exactly the right current level...?
