A lamp is made up a reflector, a base and a cover connected along their circumferences defining an inner cavity enclosing an arc tube coaxially oriented within the cavity and mounted to the base. A shroud surrounds the arc tube and is cemented to the base. An anti-glare cap and a clamping element is arranged between an end region on the side of the cover and the anti-glare cap affixed to the shroud via a clamping element.
