A PAR lamp ( 10 ) having a tungsten halogen capsule ( 12 ) mounted in a hard glass, pressed reflector ( 14 ). A hard glass lens ( 16 ) is bonded to the envelope ( 14 ) by an adhesive such as epoxy or silicone. More specifically, the envelope ( 14 ) defines a cavity ( 18 ) having a base ( 20 ) and an opening ( 22 ) defined by an edge ( 24 ), the opening ( 22 ) being opposite the base ( 20 ). The capsule ( 12 ) is mounted in the base ( 20 ) and contains a filament ( 26 ) that is designed for operation at greater than 2700K. The lens ( 16 ) is preferably a borosilicate glass and contains between 0.3 and 5 weight percent neodymium.
