Is this an LED connected to 220V AC?

I see a light that is connected in series and plugged directly to AC but I couldn't find any resistor or diode anywhere in the series connection and the wire that is connected in series is also very thin. I have two questions,

  • Is this an LED? If this is an LED which can be connected to AC supply directly ? What is the name of this specific LED?

  • As the wire looks very thin, how does it withstand AC current? I thought it would burn out but it is not.

Disclaimer: I am sorry if my questions sounds too basic but i really appreciate if someone can clarify this.

First, that is not an LED. It is a small incandescent light bulb.

Second, it draws only as much current as it needs. Incandescent lights do not need external current limiting. They are designed for a specific voltage range. As long as the voltage is correct, the current for that size bulb will be very small and handled easily by relatively thin wires.

Please post a photo of the entire light string. How many bulbs are in the string?

Totally 20 such lights are connected in series.

How much more such lights can be connected in series ?

That's a filament bulb, probably on a set of fairy lights.. 20 in series on a 240V supply is 12V each, or 6V on a 120V supply.

If it is a filament bulb or incandescent bulb then I guess it can work either in DC / AC current right?

Wanted to check, if I can add 20 more such bulb to the same series? Will there be any harm or impact in the light glow?
