Abstract
A sealed gas discharge lamp is filed with a water vapor-enriched low pressure nitrogen oxygen mixture and a storage medium such as manganese dioxide is included in a separate vessel of the lamp for additionally storing water vapor but releasing the water vapor as the pressure in the lamp drops, the release may be augmented by heating the storage medium.
