Adrian, are you aware that here in the US we still use Edison (screw) base
lamps?  One of Edison's carbon-filament creations would fit very nicely in
the reading lamp by my desk.   I don't know if it's still there, but I
recall an Edison lamp installed at a fire station in Livermore, CA that's
been burning for many decades.
Cheers,
