PROBLEM TO BE SOLVED: To provide a mercury-free composition; and to provide a lamp incorporating gallium. SOLUTION: This ionizable mercury-free discharge composition may include gallium and a halogen. The composition may be capable of emitting radiation if excited, and the composition may produce a total equilibrium operating pressure less than about 100,000 Pa if excited. This mercury-free discharge lamp 20 may include: an envelope 22; an ionizable discharge composition including gallium contained by the envelope 22; and a phosphor composition contained by the envelope 22 and in communication with the ionizable discharge composition.
