And a diode is not a bulb.

domestic mains lighting dimmers change the shape of the waveform to reduce the overall power in each AC cycle and can only be used with lamps that work with a non-sinusoidal AC supply (hence the need for dimmable LED lamps, and even then some are fussy about the waveform).
Resistive dimmers are too bulky, inefficient and get too hot to be practical in domestic lighting.

It started lighting intermittently (~1s) when switched off.

They may contain capacitors which could store sufficient charge to power the lamp for a short duration after the supply voltage has been removed.

My guess was some sort of current leakage allowing it to recharge. It died a few weeks after.

It does this by turning the power on and off around 100Hz.
Most LED drivers don’t react well to this.

I'm fine to mod your battery operated synth but don't let me rewire your house.
