PAR56

PAR56 is a designation for a Parabolic Aluminized Reflector lamp used in stage, architectural, and specialty lighting. The 56 typically refers to the reflector size, roughly seven inches in diameter, giving the lamp a characteristic wide-watt, forward-focused beam. These lamps have historically been incandescent or quartz-halogen, operating on mains voltage in many theater and architectural fixtures, and were also used in rugged outdoor and pool lighting where a sealed, robust unit was advantageous.

Construction and use: A PAR56 lamp uses a parabolic reflector to direct light from a filament or arc tube into a controlled beam. The typical form includes a protective outer lens and a sturdy envelope suitable for outdoor or damp locations. Wattages commonly seen in the traditional PAR56 family range from around 300 to 500 watts for halogen variants, with lower-power or specialized versions available in some market segments. The fixtures housing PAR56 lamps are designed to accommodate the size and mounting style of this reflector, and may be rated for low-voltage or line-voltage operation depending on the system.

Modern developments: In recent years, LED technology has produced PAR56-compatible LED modules and fixtures that preserve the familiar form factor while offering lower power consumption, longer life, and adjustable color temperature or color output. LED PAR56 units are widely used in stage productions, architectural lighting, and stage-safe underwater or outdoor installations when compatible power and control gear are available.

Applications and safety: PAR56 lamps are used in theaters, concerts, film lighting, architectural accents, and some pool or fountain lighting setups. As with any high-intensity lamp, proper heat management and electrical compatibility are essential, and replacement should occur with power removed and equipment cooled.
