IIRC (and correct me if I'm wrong), *some* power diodes will have a nasty

Around 0.6v (for silicon)
That is what I call "insignificant"
It's not the 0.6V diode forward voltage drop, if anything it's the
reverse recovery time. When the diode goes from conduction to reverse
bias there can be a short delay before it shuts off, allowing a little
reverse current to flow initially. Then it cuts off suddenly which can
cause a small transient.
Even so, not liklely to be a problem, but use of diodes like this is
unsatifactory because it makes the lights flicker enough to be
distracting. The alternative suggestion of dimming one step by switching
bulbs in series is better, or simply having several banks of lights and
switching them on and off as needed.
