This allowed more flexible electrical mounting arrangements and more precise focussing. The innovation was using the lamp rim, rather than the base, as the reference plane for focusing. Wiley of General Electric (USA) was awarded patent #3,314,331 for a miniature reflector lamp in 1967. Many run on low voltage rather than mains voltage alternating current so require a power supply.

Common sizes for general lighting are MR16 ( 16⁄ 8 inches, 51 mm) and MR11 ( 11⁄ 8 inches, 35 mm), with MR20 ( 20⁄ 8 inches, 64 mm) and MR8 ( 8⁄ 8 inch, 25 mm) used in specialty applications. MR lamps are designated by symbols such as MR16 where the diameter is represented by numerals indicating units of eighths of an inch. They are suited to applications that require directional lighting such as track lighting, recessed ceiling lights, desk lamps, pendant fixtures, landscape lighting, retail display lighting, and bicycle headlights. MR lamps were originally designed for use in slide projectors, but see use in residential lighting and retail lighting as well.
