Unusual Japanese Electric Light Bulbs

These light bulbs were all bought in Japan about 12 years ago. Because they are supposed to run on 120 volts, Tim is connecting two bulbs at a time in series. The UK mains voltage is 240 volts, but by connecting two bulbs in series, they end up getting a lower voltage passing through them.
First up is an electric light bulb that is advertised as flickering like a real gas flame. The bulb contains a long filament inside, and there is a magnet attached to the outside of the bulb. Presumably as the alternating current flows to and fro, the magnetic field created in the filament is alternately attracted to and repelled by the magnet.
We then have the Candy Light, and the Charm Light.
Finally a spectrum stick bulb.
