Electronic – What’s the voltage used to power LEDs inside an LED light bulb

led

I have opened an LED light bulb today, and there are two thick wires sticking out of the center to power the LEDs.

I know it will vary by design, but I can't find even a range of voltages, therefore I ask. What is a typical voltage used to power the LEDs in such an LED lightbulb ?

White LEDS start at 2.85V and operate near 3V. The designer chooses series, and maybe shunt arrays for redundancy to match the generated voltage. So if there were 80 LEDs that's almost a 240V string or two 120V strings.

The big contacts in the centre are for mechanical rigidity not current.
