Norman Lamps, Inc.

AR-111 bulbs are low-profile, disc-shaped reflector lamps commonly used in high-end retail displays, museums, and architectural lighting where a clean, modern appearance matters. The flat face and wide diameter (4.37 inches) create a distinctive look in track and recessed fixtures. These use a G53 bi-pin base rather than a standard screw base, which is specific to AR-111 fixtures. They're popular in commercial spaces where the lighting design calls for a minimal visual profile from the fixture.
