Re: Playing with LED Filaments.

Interesting! Have a product link for these?

It's interesting that each filament seems to want around 65 volts before they even start illuminating - that indicates that they consist of a LOT of LEDs in series internally. Based on how you describe this, it sounds like in the assembled bulb the filaments are wired in parallel and not series?

With a 65+ volt Vf, I wouldn't be surprised if these particular bulbs skip the usual driver and just use a current limiting resistor...
