Stage lighting calculations can be complex and require considerable experience. To calculate stage lighting, the lighting designer generally starts by examining the size, shape, and orientation of the performance space.
This information is used to determine the number of lights needed and the angles and levels at which to place them. Then, the lighting designer considers the type of lighting as well as the type of performance, audience size, and mood or atmosphere desired.
Once the basic parameters are determined, a light plan or diagram is created which sets out the placement of the lights and helps to create the desired lighting effects. The designer then determines the specific wattages, color temperatures and filters to be used.
Once this is complete, the final step is to program the lights so that they can be dimmed, flashed, and changed as needed – much like programming a computer.
To calculate the wattage for each light source, the lighting designer considers the size and shape of the performance space, its surface reflectivity, and the output of each lighting fixture. The desired lighting effects, and the cost of energy bills can also be factored into the wattage calculations.
The resulting wattage should be suitable for the task at hand while remaining within budget.

What is the formula for for light stage?
The formula for light stage is:
Light Stage = (Number of lights x Light intensity) / Room area
Light stage is a measure of how much light is delivered to a given area. It is calculated by multiplying the number of light fixtures in the area by the amount of light that each of them produces. This amount of light is then divided by the area of the room.
The result is a measure which can represent how brightly lit an area is.
Light stage is an important consideration when designing lighting systems. If an area needs to be illuminated to a specific level, the maximum light level (or light stage) should be determined. This figure is then used to choose the right number of fixtures and their intensity settings.
Consequently, light stage will be different for different places. A bright area, such as a stage, may require higher light stages than a residential living room.
How many LUX does it take to light a stage?
The amount of LUX required to light a stage depends on the size of the stage, the height of the stage, the type of lights used, and the type of performance. Generally, a minimum of 10 LUX is required when lighting a stage.
However, this can vary based on the performance taking place; for instance, a dance recital will require more LUX than a solo instrumentalist. For major theatrical performances, most venues require the equivalent of about 250 LUX for a medium-sized stage, and 500 LUX for a larger stage.
For a professional live concert performance, at least 1000 LUX is recommended. If the stage is located in a very large venue or space that can hold a lot of people, aiming for a LUX rating of 3000-5000 should provide a good light environment for the performers.
What is the angle for stage lighting?
The angle used for stage lighting depends on a variety of factors, including the size of the stage, the type of lighting setup, and the desired effect. Generally speaking, most theatrical lighting is usually set at around 65-75 degrees to provide wide coverage and minimize shadows.
The further out you go on the angle, the shallower the coverage will be, so you may need to position some of the lights differently to achieve your desired result. Additionally, the mood and type of show will also dictate where lights should be set.
If you’re looking for a more intense and harsher feel, then pointing the light at a sharper angle could be desired. Conversely, if you’re looking to evoke a warmer, inviting feeling, then you may want to go more towards the middle of the range.
How is the total lighting load in amps determined?
The total lighting load in amps is determined by multiplying the total number of lights by the amps per light. This can also be determined by the total watts of all of the lights, which is then divided by the total volts that the lights are working with.
Additionally, the number of lights can be adjusted by using the Voltage Drop Calculator and the Max Distance Calculator. While the Voltage Drop Calculation estimates the voltage on the farthest light, the Max Distance Calculator estimates the maximum run of lights without exceeding the appropriate wattage.
In conclusion, the total lighting load in amps is determined by multiple factors, including the total number of lights, amps per light, total watts of all of the lights, total volts, Voltage Drop Calculator, and the Max Distance Calculator.
What is a lighting load?
A lighting load is the total electrical load that is generated by the lighting fixtures in a building or space. The lighting load can be broken down into a few categories: fixed lighting, moveable and track lighting, gravity or low light level dimming, and specialty/task lighting.
Fixed lighting involves all the permanent fixtures that remain in fixed locations. Moveable and track lighting allow for flexibility and can be switched to a different position. Gravity or low light level dimming takes luminaires to a dimming level that works better for nighttime atmosphere.
Specialty and task lighting are commonly used for particular tasks such as reading, focusing on particular objects and activities, or directional guidance. Each of these lighting loads can be connected to the building’s electrical panel, depending on the size, complexity, and design of the system.
Lighting load calculations are important for identifying the amount of power that is needed to run the lighting in a space, how much money it will cost, and how much energy will be saved.
What are stage floor lights called?
Stage floor lights are most commonly referred to as footlights or floor cans. Footlights used to be created by candles or kerosene but are now powered by electric lamps. These lamps can be attached to tracks or used to emphasize certain elements in a show.
They are largely used for highlighting specific stages, figures or items. Footlights are a very effective way for a designer to create a dramatic effect that sets the right mood in a scene. Floor cans are often two or three lamped fixtures that are generally used to light a backing wall or to highlight a specific area on the stage.
The amount of adjustment you can get out of them makes them a very effective tool for design. The light they produce is usually softer and more diffused than a standard spotlight.
What do you call the lights in concert?
The lights used in concert are known as stage lighting or concert lighting. This type of lighting typically consists of spot lights, lasers, strobe lights, and colored stage lights, which all work together to create an exciting visual experience for concertgoers.
Stage lighting can also be used to make the performers stand out on a large stage, as well as to create dramatic lighting effects during dramatic parts of a show. Stage lighting can also be used to bring focus to key parts of the show, such as when a singer sings a solos.
What are the lights called for the Twin Towers?
The lights that illuminates the former Twin Towers of the World Trade Center in New York City are known as Tribute in Light. The Tribute in Light project was created by lighting designers Paul Marantz and Gustavo Bonevardi, who worked with the Municipal Art Society of New York, to commemorate the first anniversary of the 9/11 attacks.
The installation consists of 88 searchlights – each illuminated by 7,000 watts of energy – placed in a pair of 48-foot squares, mirroring the former location of the Twin Towers. These lights create two vertical columns of light that can be seen from up to a maximum of 20 miles away.
Although this light show was initially meant for the single evening of the anniversary, it was so well-received that it has been making regular appearances each September 11th ever since.
What lights are used for church stage?
As the type of lighting used for a church stage will depend on a variety of factors such as the size of the stage, the type of activity taking place on the stage, the budget of the church, and the desired lighting effect.
Generally, many churches use a mixture of traditional theatrical and modern LED lighting to light their stage.
Traditional incandescent lighting, such as Par cans and fresnels, is a relatively inexpensive and versatile option for lighting a church stage. Additionally, LED fixtures are becoming increasingly popular for church stage lighting as they are energy-efficient, long-lasting, and are available in a variety of colour temperatures and beam angles.
LED moving heads, also known as “intelligent lighting,” can be used to add interest and texture to the stage, as well as providing special effects such as rainbow effects, strobes, gobo effects, and scenery changes.
Other types of lighting used by churches include spotlights, lasers, and gobo projectors. Spotlights are versatile and allow for precise control of the light focus. Lasers can be used to add a dramatic effect to a performance, while gobo projectors can be used to project images onto the stage.
Additionally, wired and wireless dimmer systems can be used to control all types of lighting on stage.
Finally, churches should also consider adding stage wash and ambient lighting to their setup. Stage wash lights are used to create even lighting on the entire stage, while ambient lighting is used to create atmosphere and ambiance.
In conclusion, the type of lighting used for a church stage will depend on numerous factors. Churches should carefully consider their budget and stage requirements when deciding what type of lighting to use, but LED lighting, traditional theatrical lighting, spotlights, lasers, gobo projectors, dimmer systems, stage wash, and ambient lighting are all potential solutions.
