Abstract
A dual emitter light assembly employs a reflector having a pair of concave reflector dishes. Each dish is associated with a lamp socket. Each concave dish comprises at least three parabolic reflector surfaces having a common focal point. The axes of the parabolas of revolution which define the reflector surfaces are non-parallel and lie in a common plane, the axis of both dishes lying in the same plane.
