Ok, I'll have to read that item later due to shortage of time right
now, but I'm harking back over 40 years to the first generation of
LEDs which were used for panel illumination on electronic instruments.
They'd typically draw about 15mA before going phut and were dimmer
than the filament bulbs they were replacing. That's if my memory is
not letting me down, that is.
