P
P PATTERN
A sequence of lighting changes.
P2
Lighting Industry Forum code which identifies the (original) recommended usage of different lamp types. P2 coded lamps are photofloods, and have a color temperature of 3000°K.
PAGE
Some theater announcement systems use the term "PAGE" to mean making a call.
A way of increasing the functionality of a control on a lighting desk. For example, most computerized lighting desks with SUBMASTERS will allow you to store more than one lighting state in each submaster. Each group of submasters is given a page number which is used to select which set you want to use.
PAGEANT
Brand name of a 1000W beamlight made by Strand Electric in the UK. Produced a near parallel beam and had a set of spill rings on the front to minimise glare.
PAIRING
Connecting more than one lantern to one power outlet via an adaptor or splitter, or more than one speaker to one amplifier channel.
PAN
- A control on a mixing desk which allows the operator to position the channel's output in the final stereo image (L - R).
- A horizontal (side-side) movement of a camera or a moving light. Short for Panorama.
PAR
Short for Parabolic Aluminised Reflector lamp. A lamp containing a filament, reflector and lens in one sealed unit. Used in PARCANs to produce a high intensity narrow beam of light. Par lamps are available in many different sizes and powers. Par sizes available include 16, 36, 38, 56 and 64. (The number refers to the diameter of the lens, in eighths of an inch). The most common for theater use are Par 64s rated at 1000W (1kW), although other wattages are available. 110V Par lamps are often used in large UK venues or for touring due to the increased light output. Because the current is greater, the lower voltage lamps have smaller thicker filaments which give a more focussed beam than the thinner 240V filaments. In the film business, PAR lamps are known as "bird's eyes" after the alleged inventor Clarence Birdseye.
PAR CAN
A conventional lighting fixture which represents the original workhorse of the rock and roll touring industry. A PAR can is comprised of a PAR (Parabolic Aluminized Refelctor) lamp and a mounting fixture and base (the can). Standard PARs range in size from 4.75" (PAR 38) to 8" (PAR 64). The most common configuration for touring use is the PAR64. The PAR64 is usually fitted with a 1000 watt narrow or very-narrow beam PAR lamp. ACLs are often substituted for PAR lamps.
PAR LAMP
Parabolic type lamp available in various spread patterns & wattages.
PAR LAMP / PARABOLIC ALUMINIZED REFLECTOR
An incandescent or tungsten-halogen incandescent lamp with a hard glass bulb and an interior reflecting surface, a precisely placed filament, and a lens to control beam spread. The lens is hermetically sealed to the reflector. Metal halide PAR-lamps are also now available.
