1980's.

The outer bulb is coated with yttrium vanadate (YVO₃), a colour-correcting phosphor: some of the ultraviolet radiation from the discharge is converted into more useful red wavelengths in order to improve the colour rendering.

Life: 10,000 - 15,000 hours.

Thanks to Péter Horváth (Fénymúzeum – Museum of Electrical Lighting and Industrial History, Hungary) who donated this lamp.
