The cap (10) of the capped electric lamp (1) has a resilient member (14) which acts transversely to the axis (10') of the cap. This allows the lamp to be used in a lighting system having the lamp and a reflector (40), in which the reflector is of a simple construction. The resilient member (14) presses reference locations (13) of the cap against flat mounting surfaces (50) in the reflector, which are located on the legs of a V. The cap (10), and thus the electric element (3) inside the lamp vessel (2), is as a result accurately positioned in the reflector in two directions transverse to the axis. The cap (10) may in addition have transverse projections (23, 24, 25) distributed over its circumference, by which the cap is able to keep itself fixed in the reflector (40) also in an axially aligned position through cooperation with ridge portions (46, 47, 48) of the reflector.
