You then screw this entire thing into the socket. It's called a "bulb

The RMS voltage across the bulb is reduced by ~29%.

Ooh, DejaVu, I think we've had this discussion before...

The bulb savers that I used back in the '70s were varistors. They
slowed down the turn-on of the light. They were low resistance when
warm, and high when cold. There was no diode.
