Abstract
A lamp to produce white light includes an envelope; and a composition disposed in the envelope and including an initiator; a primary halide; and a secondary halide, wherein the primary halide, in a presence of the secondary halide, has a vapor pressure that is greater than a vapor pressure in an absence of the secondary halide, and the composition is configured to emit white light in a presence of an electrical discharge in the envelope.
