Norman Lamps, Inc.

A Norman Lamps PAR 46 is a specialized directional lamp built with a Parabolic Aluminized Reflector. The "46" indicates its diameter is 46 eighths of an inch, making the face of the bulb nominally 5.75 inches across. Norman Lamps designs these heavy glass sealed beam lamps to feature waterproof construction and precise beam spreads. Depending on the specific model, these bulbs connect to fixtures using various bases, such as screw terminals, brass slip-on terminals, or medium side prong bases.

Norman Lamps offers the PAR 46 in a wide variety of voltages and wattages to suit specific electrical systems. Their inventory includes 32V 150W models, 115V 150W lamps that output 1,750 lumens, and 130V 200W versions. These bulbs are often built with an internal halogen capsule or quartz-halogen technology to provide fully dimmable operation and sustained lumen output over a long lifespan, which can reach up to 6,000 hours in certain traffic signal models.

Because of their durable sealed construction and sustained lumen levels, Norman Lamps PAR 46 bulbs are utilized across demanding commercial and transportation environments. They are engineered for specialized vehicular uses, including high-performance motorcycle lights and heavy-duty locomotive headlights for rail applications. Additionally, their wet location certified models are widely used as reliable traffic signal lamps, while medium flood versions provide clear, diffused lighting suitable for various commercial needs.
