You really can't get any more classic than the Watt ceiling lamp at John Lewis.
As the name suggests and the images show, this is a ceiling lamp based on the light bulb. Indeed, it's a bulb within a bulb, that larger outer bulb made of glass and with a brushed chrome finish, holding a 25w bulb for the light.
Sold with a 130cm drop of cable, it's yours for £45.
