A glass extension (,) with a cavity (,) for an amalgam (,) is added to an exhaust tube (,) or a flare (,) of a fluorescent lamp. The mouth (,) of the cavity (32) is provided with a bimetal valve having a cover portion (,) to close the cavity (,) when the lamp is cold and to open the cavity when the lamp is hot. The amalgam (,) is a metallic amalgam of, for example, mercury or other know suitable materials for establishing a metallic vapor equilibrium during operation of a discharge lamp. The amalgam holder helps to maintain optimum mercury vapor equilibrium at start-up, and to reduce the effects of mercury vapor starvation resulting from off-times.

The formation of leachable mercury upon disposal or during TCLP testing of mercury vapor discharge lamps is substantially prevented by incorporation of an organic or inorganic metal mercury antioxidant in the lamp structure or in the test solution.
