Choosing the Right Theater Spot Lights
Theater stage lighting involves a lot of different techniques. Choosing the right equipment for your space is important to ensure that you’re getting the best results.
Ellipsoidal spotlights can be framed and focused in many ways, but they’re not as versatile as PAR lights, which can spread their broad beams over large areas.
Fresnel Spotlights
Fresnel spotlights are a staple in the theatre industry. They are easy to use, portable and durable. They can be used as a fill light, key light and anything in between. They also come with many accessories that allow you to manipulate the intensity and change the colour. This allows you to create a variety of lighting setups, including High Key lighting which is ideal for commercials.
A fresnel lamp has a lens in front of the bulb that helps to focus the light rays and can be adjusted to become either a narrow spot light or a wide floodlight. It is named after its inventor Augustin-Jean Fresnel, who was able to reduce the weight of large spherical lenses by carving out concentric rings in a flat lens.
The Fresnel can be attached to a set of barn doors that can be placed around the lens to direct the beam and prevent it from spilling over into unwanted areas. It can also be attached to a round scrim that will help to reduce the intensity of the light. The light can also be connected to a dimmer switch or control board to allow you to set the intensity levels.
The ellipsoidal spot is similar to the Fresnel spot, but it can throw the light much further and with greater distance because of its wider lens. It is a good choice for front lighting on larger stages and venues. Like a fresnel, it can be attached to various accessories, such as barn doors and round scrims. It can also be connected to a dimmer and control board to adjust its intensity level according to the lighting design plan.
Moving Head Spotlights
Perhaps no single innovation has affected stage lighting more than the moving head spotlight, invented in rock shows and used in theaters today. These automated lights allow for a wide range of movement, color and effect options, which can be synchronized to music and other effects. They’re popular with dance performers, concert productions, and other events, especially those that require high-quality, dynamic lighting displays.
A moving head light can produce a variety of different effects, including spotlights, wash lights, and beam lights. Spotlights create a narrow beam of light, ideal for accenting specific areas of the stage or objects. Wash lights, Moving head light supplier on the other hand, produce a wider field of light that can be used for general illumination or creating a mood and atmosphere. Beam lights, the narrowest of the three, are often used for aerial effects.
Many modern moving heads come equipped with a number of control options, including multiple gobo wheels, a mechanical dimmer, and zoom functions. They can also be controlled using the DMX protocol, making them easy to integrate into larger lighting rigs and effects systems. Some also have a feature that allows the user to view a rendered preview of the output produced by the fixtures, which makes them easy to program and synchronize with other lighting effects.
In addition to their versatility, moving head spotlights are typically more energy efficient than traditional stage lights, saving money on electricity costs. Additionally, some models offer a “smart” feature that can automatically adjust the output of the fixture based on an external input signal.
Followspots
The Followspot is a powerful operator-driven stage lighting instrument used to follow actors or presenters with a beam of light as they move around the stage. They are most often used in musicals, rock shows or large scale presentations that require a mobile spotlight to highlight key individuals. They can be mounted in the wings, a purpose built Spotlight Booth or on a catwalk.
Modern LED follow spots are available in a range of sizes and throw distances. Most models feature an iris control to change the size of the beam, from a small head shot to a full body wash. Some have internal color gels to change the color of the beam and a shutter for on/off.
In Theatre productions nowadays it is common to have three, four or six Followspots in operation at any one time. Depending on the style of show and venue there may be cues that are only outlined for the Followspot operator in a plot sheet, this can include things like ‘head & shoulders’ or ‘full body’. It also specifies the intensity of the light and whether it needs to have a soft (frosted) edge or be sharp.
The design of a good quality Followspot is challenging and has to achieve a balance between a powerful and stable beam, dimming ability and gobo projection all within an ergonomically designed package. Robert Juliat are the industry leaders in this area, producing high quality Followspots which are used throughout the world in venues from the smallest cabarets to the largest stadiums.
Spotlight Dimmer
A spot light dimmer is a small device used to control the amount of light produced by a spotlight. The device works by altering the current flow from the fixture, increasing or decreasing the brightness of the beam. It’s often mounted in the gobos or on the body of the lantern, and can be adjusted to suit the needs of the production.
Lighting has the power to draw the audience’s focus and Theater spot lights create a sense of drama. While spotlights are a crucial tool for creating focus, most productions will need a variety of other types of lights to help tell the story. Using the right tools will ensure that your production is successful.
When a show is over, it’s important that the audience knows when to leave. The use of lighting can help mark this moment through the subtlety of a shift in mood or the directness of a spotlight.
Often referred to as IWBs, internal wired bars are an integral part of most theater lighting systems. They feature cabling within the bar that connects to a dimmer or patch panel at one end, with sockets numbered for reference. Some lighting bars also have DMX outlets or hot power sockets for additional equipment.
