The Bulb Factory: How vintage filament bulbs are made by hand

Jazzy music plus light bulbs made by hand! This promotional video from William & Watson in London, England demonstrates how their vintage filament bulbs are put together and tested. From Wikipedia:

An incandescent light bulb… is an electric light with a wire filament heated to such a high temperature that it glows with visible light (incandescence). The filament, heated by passing an electric current through it, is protected from oxidation with a glass or quartz bulb that is filled with inert gas or evacuated… The light bulb is supplied with electric current by feed-through terminals or wires embedded in the glass…

Incandescent bulbs typically have short lifetimes compared with other types of lighting; around 1,000 hours for home light bulbs versus typically 10,000 hours for compact fluorescents and 30,000 hours for lighting LEDs.
