Hi,
I need to hack together a power supply for an "illuminator".
Bulb is rated 6.5V 2.75A.
Easy solution is a DC "brick".
However, I think the original power supply was probably just
a transformer (i.e., driven with AC, no regulation (?)).
This got me thinking as to whether there *is* a difference
driving incandescent lamps with AC vs. DC -- i.e., what would
the mains frequency have to be in order for there to *be* a
difference?
And, how would that difference manifest itself, otherwise.
