They were called "beehive" bulbs, and we had one as a nightlight when we were kids. It had a lovely pink colour, and lasted about 10 years (≈20,000 hours) until it finally got broken, by which time they were no longer being made.
They also produced an argon one (purple/UV) for rock hounds (of which I'm one), which I'd love to get my hands on.
