not of its a capacitor or an inductor.
frankly a choke and a full wave bridge and a smoothing cap is all you
need. Shove the LEDS in series.

Same as a fluorescent in principle, less the starter ********.
Fluorescent tube is just like an HV LED in general electrical
characteristics, once 'lit'.

Not very 'dimmable' mind you.


Interesting idea - use perhaps a 12-24V high frequency AC supply and
replace the classic series resistor with an inductor. Put the high power
LEDs back to back in parallel.

That might be scalable to adding arbitrary numbers of lamps in parallel
with a generic range of PSUs (by max power rating).

I guess if you are clever the dimming could be handled by the PSU as it
is by dimmable SELV PSUs
