Stage lighting instruments are used in stage lighting to illuminate theatrical productions, concerts and other performances taking place in live performance venues. They are also used to light maakeup studios and sound stages. In the USA, lighting fixtures are called « instruments » or « units. This article mainly uses terms common to the USA.

Although lighting instruments may look and operate differently, they all have the following components:. A metal or plastic container to house the whole instrument and prevent light from spilling in unwanted directions.

This comprises all of the exterior of the fixture except for the lens or opening. The housing may be designed with specific elements that help reduce heat and increase the efficiency of a lamp. Older instruments were made from rolled and machined steel makepu aluminum; however, instrujent the advent of the Source Fourmany lighting instruments are being made from die-cast metal. Instrkment allows for one single, light-weight piece that is more economical to produce and use.

Some instruments are made from plastic, such as the Selecon Pacific. The gap in the housing where the light is intended to come out.

The lens and the reflector, along with other beam altering devices are part of the optics system. This affects the quality and directionality inetrument the light output. An Ellipsoidal Reflector has a lamp set at one focus of an ellipse, bouncing the light and focusing it at the second focus of the ellipse.

This allows the light to spot. A Parabolic Reflector has insrtument lamp at the focus of a parabola, bouncing the light in parallel lines away from the reflector. There is no point at which the light converges, leaving an unfocusable light, mkeup the more flood characteristics. A reflector is located behind or around the light source in such a way as to direct more maakeup towards the lens or opening. Each unit has a characteristic reflector, used in conjunction with the lens or lack there of to create the light that a designer may use.

Most instruments are suspended or supported by a « U » shaped yoke, fixed to the sides of the instrument providing an axis of rotation.

The yoke is connected to the pipe or batten by one of the clamps mentioned below; it may also be affixed to the deck with floor mounts, or attached to the set with a stage screw. A C-Clamp utilizes a threaded bolt to prevent the clamp falling off the bar and also to instrumeny the clamp from moving.

In Europe, a hook clamp is used. The shape of the hook clamp prevents it from falling instruument the bolt stops the clamp from moving. Once secured, the insstrument can be panned and tilted using tension adjustment knobs on the yoke and clamp. A side arm is a longer arm attached to the light fixture with a C Clamp on the end. This enables the light to be hung to the side of an electric as opposed to below it.

Most theatrical light bulbs or lampsthe term usually preferred are tungsten-halogen or quartz-halogenan improvement on the original incandescent design that uses halogen gas instead of an inert gas to increase lamp life and output. Fluorescent lights are rarely used other than as work lights see below because, although they are far more efficient, they cannot be dimmed run at less than full power without using specialized dimmers and they inshrument not dim to very low levels.

They also do not produce light from a single point or easily concentrated area and have a warm-up period, during which they emit no light or do so intermittently. High-intensity discharge lamps or Makehp lampshowever, are now common where a very bright light output is required — for example in large follow spotsHMI hydrargyrum medium-arc iodide floods, and modern automated fixtures.

When dimming is required, it is done by mechanical dousers or shutters, as these types of lamps cannot be electrically dimmed. Some specially designed fittings now use light-emitting diodes LEDs as instrumnet light source.

LEDs are ideal where an intense but unfocused light source is required, such as for lighting a Cyclorama. Conventional non- intelligent lighting fixtures are designed to accept a number of different accessories intended to assist in the modification of the output. The most common, found on almost all stage lights, is the gel frame holder. The gel frame holder is intended to hold gelmounted in cardboard or metallic gel frames.

Other common accessories include gobo holders or rotators, iris holders, donuts, Barn doors and color scrollers. Lighting instruments can be broadly separated into two categories: The distinction has to do with the instrumdnt of the light produced by the instrument, with spotlights being a potentially tightly focused light, and floodlights being diffuse light.

Instruments that fall somewhere in the middle of the spectrum can be classified as either a spot or a flood, depending on the type of instrument and how it is used. Like an old-fashioned automotive headlight the reflector is integral to the lamp and the beam spread maekup the unit is not adjustable except by changing majeup lamp.

PAR lamps are widely used in architectural lighting and may often be found at hardware stores. PAR lights have seen heavy use in rock and roll shows, especially those with smaller budgets, due to their low cost, light weight, easy maintenance, and high durability. They are also often used as top or side lights in the theatre and for special effects.

All PAR lamps except those with narrow or instrumennt narrow lenses produce an intense oval pool of light, insgrument with fixed focus and soft edges.

The « number » associated with a PAR light e. Par 64, Par 36, Par 16 indicates the diameter of the lamp in 8ths of an inch. The beam angle is determined by the lamp.

Each angle has two numerical values since the beams are elliptical rather than circular. PAR-bars are aluminum pipes with par cans permanently attached and circuited through the pipe. Par-bars with 4 instruments are often referred to as 4-barsand par-bars with 6 instruments are referred to as 6-bars.

Ellipsoidal Reflector Floodlightsbetter known as Scoop lights or scoops are circular fixtures that do not have any lenses. They have a reflector at the back of the fixture that directs the light out of the fixture.

Since they do not have any sort of lens system they are cheaper than other fixtures. Scoops are most often used to flood the stage with light from above, or to light backdrops. Occasionally they are used as worklights, which are lights used during non-tech rehearsals and during set work.

House lights provide light on the theatre’s seats and aisles for the audience before and after performances and during intermissions. They are generally incandescent lights, however fluorescent lights or scoops may be used in some instances. House lights are often controlled by dimmers, but are sometimes on simple switches. Worklights provide general lighting backstage or in the houseand are often fluorescent fixtures.

Work lights are almost always switched only. House and work makuep are usually off during performances but are occasionally included in the lighting inztrument to establish focus or emphasize plot elements. When the house lights are not on a dimmer, the switch is usually under the unstrument of the stage manager. LED stage lighting instruments are stage lighting instruments that use light-emitting diodes Instrment as a light source.

LED instruments are an alternative to traditional stage lighting instruments which use halogen lamp or high-intensity discharge lamps. Like other LED instruments, they have high light output with lower power consumption. Most LED fixtures utilize three or more colors usually red, yellow, and blue which can be mixed to theoretically create over 16 million different colors.

LED stage lights come in three main types. PAR cansstriplights [ 14 ] and ‘ moving head ‘ types. Moving head lnstrument can either be a bank of LEDs mounted on a yoke or more conventional moving head lights with the bulb replaced with an LED bank.

A spotlight is general term for any lighting mxkeup used in theatre to create a pool of light on the stage. The lens is named after French physicist Augustin-Jean Fresneland consequently pronounced with a silent « s ». The distinctive lens has a ‘stepped’ appearance instead of the ‘full’ or ‘smooth’ appearance of those used in other lanterns. Another method of controlling the spread of light is to use either a snoot also referred to as a top hatwhich generally limits the light coming out, or a barn doorwhich allows the flaps to work as though they were shutters on an ERS.

insrument Fresnels use a spherical reflector, with the lamp at the focus. The lamp and reflector remain a fixed unit inside the housing, and are moved back and forth to focus the light. This is done by a slider on the bottom or kakeup of the lantern, or by a worm track. Instrumentt very tight focus, the lanterns are the least efficient, as the least light can escape the housing. Therefore Fresnels are not good for tight focus on small areas.

They are most often used at medium distances from the stage for area lighting. The fixture is more versatile, allowing for a flood or a softer spot. The flexibility of the ERS allows it to fulfill the bulk of lighting roles in the theatre, from broad area lighting to tight specials ; from long throws from the back of the auditorium to shin kickers on the stage.

The major parts of an ERS light are the casing in which the internal parts are mounted, an ellipsoidal reflector located in the instrumenr of the casing, a lamp mounted so the filament is positioned at the rear focal point of the ellipsoid, a dual plano-convex lens two instruemnt lenses facing each other in the barreland at the front, a gel frame to hold the color gel.

The light from the lamp is efficiently gathered by the ellipsoidal reflector and sent forward through the gate, shutters and lens system. Instead, an ERS is known by its brand nameor called a « profile spot » after its ability to project the silhouette or profile of anything put in the gate. Most manufacturers now use field angle to indicate the spread that the fixture has. However older fixtures are described by the width of the lens x focal length of the instrument.

For example, a 6×9 ellipsoidal would have instrumdnt 6″ lens and a focal length of 9″. This nomenclature was used because traditionally, the larger the lens, the more light output, however this is no longer true so most manufacturers now identify their fixtures by beam angle and light output.

As the field angle narrows, the instrument can be used further from the stage. A beam projector is a lensless instrument with very little beam spread. The primary reflector is a parabolic reflector and the secondary reflector is a spherical reflector.

The parabolic reflector organizes the light into nearly parallel beams, and the spherical reflector is placed in front of the lamp to reflect light from the lamp back to the parabolic reflector, which reduces spill.

The result is an intense shaft of light that cannot be easily controlled or modified. The beam projector no longer is used to the extent that it once was, as newer makeip and PAR lamps have created easier ways to produce the effect.

The followspot also called a trackspot or dome is a lighting instrument that is moved, by an operator or by DMX control, to emphasize or provide extra illumination and usually to ‘follow’ a specific performer, especially when he or she is moving around the stage. When most people use the term « spotlight » they are referring to the follow spot.
