The electric lamp has a quartz glass lamp vessel (10) in which an electric element (3, 4) is accommodated. The lamp vessel locally has a light-absorbing, non-reflective coating (11, 12). The coating mainly consists of 2 to 10 % by weight of glass which is free of lead oxide and has a softening point between 600 and 700 DEG C. Iron 50 to 60 % by weight, primarily in metallic form, and manganese oxide, 30 to 55 % by weight, are dispersed therein.
