An energy efficient fluorescent reflector lamp includes a fluorescent light source enclosed in a reflector with a defined cavity and circumferential rim defining a light emitting opening, and a circumferential flange at a mating opening. The reflector cavity enclosed with a lens at the rim, has an interior wall as a reflective surface for directing light out from light emitting opening. The fluorescent light source is attached to a base located inside the reflector cavity and located inside the mating opening. The circumferential flange diameter is larger than a diameter of the mating opening. The base is assembled and locked together with a ballast housing of defined space sufficient to accommodate an electronic ballast and an electricity supply base. The ballast energizes the fluorescent light source to emit light, and the ballast includes power input terminals connected to said electricity supply base and output terminals connected to said fluorescent light source. The fluorescent reflector lamp has luminous efficacy which exceeds that of corresponding halogen reflector lamps while having an overall outline fitting substantially within the ANSI specified outline for PAR lamps
