Abstract: A negative glow discharge lamp including a light transmitting envelope having supported therein electrode means for establishing a negative glow discharge in the lamp. The fill material includes a metal-based gas such as sodium which, upon excitation thereof, directly emits visible light. The sodium has a resonance radiation in the visible part of the spectrum. The cathode is a hot cathode.
