Abstract
A lens casting or housing provides a series of grooves for selective mounting of various lenses to achieve various beam spreads. By spacing lenses in the housing, it is possible to reduce the diameter and thickness of the lens nearer the light source with consequent improvement in thermal characteristics as well as efficiency in light transmission.
