The light looks like an industrial accident, a siamese twin of a light made by mistake.
However, once the bulb is plugged in, you can see its visual trickery.
The light, when plugged into a pendant, looks as if it will fall off its base any moment.
It makes the light into a more delicate, almost temporal, object.
The secret of this bulb is, it has two bayonet caps. You can use one bayonet cap, the other is just an ornament.
