This is almost certainly nitpicking but since there's enough other
review comments that you will have to respin anyway ;-)

Is an LED really "usually powered by a voltage/current regulator"? Some
LEDs have a software controlled power supply but I'm not sure it is
the usual case.

Likewise its a little confusing to be talking about LEDs with an
external current regulator since, although that is possible, it is also
one the main features provided by LED driver chips.
