Yes, I made an error, a boo boo, a mistake on terminology. I admit it. I shall now step away and resign myself to washing cars for a living.
"Linear DC is regulated DC, but not all regulated DC are linear DC. Bridge-rectified filtered DC is not regulated DC or linear DC."
I still think this is an interesting topic for exploration / discussion.
If a switched mode "AC only" power supply has rectification to DC, filter caps, then its own AC frequency generator before it hits the isolation transformer... then it will work on DC. DC of any polarity will "rectify" to DC and away we go.
SMPS are becoming popular everywhere now for energy efficiency purposes and smaller/lighter design, and most everything with a SMPS can probably handle DC as input at the same voltage as AC RMS without any difficulty.
Yes, anything that depends on the specific properties of AC power such as the frequency, won't work and will act as a resistive element on DC. Induction motors, synchronous motors, shaded pole motors simply won't work, and may burn up from overcurrent.
But it appears theoretically possible to have a dual purpose AC/DC "resistive/inductive ballast" which is a wire wound resistor that acts inductively on AC and resistively on DC. Though it is likely that most inductive ballast AC fluorescents probably don't bother.
A fume hood with forced-air exhaust is probably a good idea for initial testing.
