The LEDs: current operated devices (only).
fluoros: current (conventional connection) and voltage (the intense
electric fields attract/repel/form ions in the TC case. However, in
effect an AC current is present in the tube although it may not be
longitudinal depending on tube orientation relative to the TC.
Incandescent: Normally current. However, voltage also to light up the
gas in a similar fashion to the fluoro. Ion bombardment of the
filament under this condition can cause the filament to incandesce.
Also implied is a current flow (moving charges).
In all cases a current flow is present since lighting takes power.
