could have model-specific, nonstandard-shape headlamps, using any of a wide variety of replaceable light bulbs. Between 1940 and 1956, all U.S. cars had to have two 7-inch (178 mm) round headlamps with dual filaments, so each lamp provided both a high and a low beam light distribution. In 1957, a system of four sealed-beam headlamps—two per side, of

PAR38 lamps, with an E22 base and with ratings up to 150W, were often used for domestic outdoor floodlight illumination for patios, backyards, and often combined with a PIR sensor switch as a security/convenience light, for example, in a driveway. Coloured versions were popular with discos and mobile

Depending on the parabolic reflector geometry, the configuration of the filament and its placement within the paraboloid, PAR lamps can achieve a wide range of beams, from narrow spot to wide flood. The following suffixes are commonly used with PAR lamps to indicate their beam width: PAR lamps are

In the United States of America, sealed-beam headlamps were introduced in 1939, becoming standard equipment across all American-market vehicles starting in 1940 and remaining the only type allowed for almost four and a half decades, until the 1984 model year. Before and after those years, vehicles

High-power, mains-voltage, theatrical PARs usually use the bi-pin GX16d "Mogul" lamp connector; G9.5 and variants are common too. Theater metal-halide lamps use G12. In addition to being used on light bulbs themselves, the G38 connectors are also found as a part of the Raylite reflector assembly,

PAR lamps come in a variety of standardized sizes. The size of a round PAR lamp is expressed as the nominal diameter of the mouth of the reflector, in eighths of an inch—so the approximate nominal lamp bell diameter in inches can be found by dividing the PAR size by 8. A PAR56, for example, is 56

inches (146 mm) diameter, was allowed in some U.S. states. The following year in 1958, all states allowed the new system. Two of the lamps contained two filaments and served as low and high beam, while the other two lamps contained only one filament and were active only during high-beam

eighths of an inch (7 inches) in diameter; a PAR36 is 36 eighths (4.5 inches) in diameter, and so on. Similarly, the diameter in millimeters can be found by multiplying the PAR designation by 3.175. For example, a PAR16 lamp is approximately 2 inches or 50.8 mm in diameter.

A PAR lamp consists of a light source, with lens and a parabolic reflector with a smooth aluminium surface determining the spread of the beam. The most common sealed beam type combines these three elements into an integral unit. The light source usually approximates a

The size of rectangular PAR lamps is expressed as the letters REC followed by the reflector's mouth height, the letter "X", and the reflector's mouth width—with both dimensions in millimeters. For example, REC142X200 lamps are 142  high and 200 mm wide.

although some Raylite reflectors have "tails" which then require connection to the mains flex with the use of a ceramic connector block (ideally fixed to the can's body).
