Abstract

A H.P. discharge lamp comprises a closed discharge vessel containing a rare gas, Hg, Tl, In, Na and I as described in Specification 1,008,339, except that the quantity of Tl is 3-10% by weight of Hg, plus a quantity of Li greater than that which would evaporate during normal operation, the vessel operating at above 600 C.
