The LED option may not work - depending upon your goals
LEDs operate between 1.5-2 VDC
so a 'dimmable LED bulb' has a Circuit in the base that can take the nominal output from a 120 VAC dimmer and make it vary to support the LED array (usually multiple individual LEDs wired in series)....

If you want a variable Power supply, Assuming Voltage, a Variac will work wonderfully, with good meters.
If you want to vary frequency...
You'll need a Variable Frequency Drive, and that will need to be sized for the load...
Happy Listening
you may be better off with a variac and a current meter - Chip647 09:33:08 02/16/25 (0)
