MR11 Halogen Light Bulbs
are 11/8" (1 3/8") diameter reflector type light bulbs with 2 pins
on their base. MR11 light bulbs are low voltage (between 6 and 24 volts) and
have either a DC (BA15d) or G4 base (sometimes called a GZ4). These bulbs are
often listed by a 3 letter code called an ANSI Code (i.e. FTD, GBF) that identifies
the bulbs wattage, voltage, base, and beam spread. MR11 Halogen Light Bulbs
are used for fiber-optic decorations, novelty lamps, fountains, display cases,
track lighting, and landscape lighting. Like MR8 light bulbs, MR11 light bulbs
are available in a variety of beam spreads.
