Abstract:
A mercury-free discharge composition is provided. The mercury-free discharge composition may include Titanium, Zirconium, Hafnium, or combinations thereof, and a halogen. The composition may be capable of emitting radiation if excited, and the composition may produce a total equilibrium operating pressure of less than about 100,000 pascals if excited. A mercury-free discharge lamp is also provided. The mercury-free discharge lamp may include an envelope; an ionizable discharge composition including Titanium, Zirconium, Hafnium, or a combination thereof applied within the envelope.
