Natural light can’t be turned down or turned off the way artificial light can. This element of control is crucial for auditorium settings. When calculating the lighting needed, never include natural light in the equation since it will usually be more of a hindrance than a blessing.

- Scoop lights.
- House lights and worklights.
- LED stage lights.

What is value of illumination for auditorium?
An illuminance level of 500 lux is therefore recommended. At the same time, the lighting must be dimmed down during videos or screen based presentations. To avoid glare during lectures is necessary and the glare rating should not be above 19.
What are the lighting and ventilation requirements in an auditorium?
One-tenth of the floor area excluding doors for dry hot climate. ii. One-sixth of the floor area excluding doors for wet/hot climate. No portion of a room should be assumed as lighted if is more than 7.5m away from the door or window which is taken for calculation as ventilating that portion.
Is standard for lux level?
Today the light level is more common in the range 500 – 1000 lux – depending on activity. For precision and detailed works the light level may even approach 1500 – 2000 lux.
Indoor Light Levels.
| Activity | Illuminance (lx, lumen/m2) |
|---|---|
| Public areas with dark surroundings | 20 – 50 |
| Simple orientation for short visits | 50 – 100 |
What is a good Lux level?
Recommended Light Levels by Space
| Room Type | Light Level (Foot Candles) | Light Level (Lux) |
|---|---|---|
| Retail Sales | 20-50 FC | 200-500 lux |
| Stairway | 5-10 FC | 50-100 lux |
| Storage Room – General | 5-20 FC | 50-200 lux |
| Workshop | 30-75 FC | 300-750 lux |
What is a scoop light?
In stage lighting, an ellipsoidal reflector floodlight (sometimes known by the acronym ERF which is often pronounced “erf”), better known as a scoop, is a large, simple lighting fixture with a dome-like reflector, large high-wattage lamp and no lens.
What height should auditorium be?
Auditorium Stage
Assume that the typical stage is 30-35 feet deep with a proscenium opening of 40-50 feet wide, and up to 30 feet tall. The side stage should be at least half the size of the proscenium opening on each side.
What are the requirements for good acoustics of an auditorium?
According to classic acoustics theory there are five requirements which, when met, result in good acoustics:
- an appropriate reverberation time.
- uniform sound distribution.
- an appropriate sound level.
- an appropriately low background noise.
- no echo or flutter echo.
Is auditorium the same as gymnasium?
As nouns the difference between auditorium and gymnasium
is that auditorium is a large room for public meetings or performances while gymnasium is a large room or building for indoor sports.
What is selective visibility?
1. Selective visibility: the lighting designer makes the stage visible to the audience; he also selects what should be seen and what should not be seen at any point in the play.– or a highly stylized effect by lighting the stage in a way that could not possibly come from “real” sources.
What kinds of things can lighting add to a show?
Functions of lighting
- Selective visibility: The ability to see what is occurring on stage.
- Revelation of form: Altering the perception of shapes onstage, particularly three-dimensional stage elements.
- Focus: Directing the audience’s attention to an area of the stage or distracting them from another.
How much natural light is required for a habitable room?
For example: For a 20m2 room the minimum area required for natural light is 10%. If a rooflight is installed only 0.6m2 would be required. If the roof light was only 0.3m2, then a window or equivalent borrowed light would be necessary.
What is natural light and ventilation?
A natural ventilator is an effective way to help bring fresh air and natural light into a building. By placing vents to let the stifling air out at the ceiling level and intake openings on side walls at the floor level, air will move throughout the interior space.
What is light ventilation?
Simple, natural light cuts down on the need for artificial illumination and therefore can save energy.When a window or door in one room will provide light and ventilation to another room then the area of both rooms must be calculated together as one and the window or door must qualify for the entire area.
What is DMX lighting?
DMX is an acronym for Digital Multiplex. It is the standard digital communication protocol that is used to remotely control intelligent lighting fixtures.
How many lights do you need for stage?
My rule of thumb is to have two lights per zone on the stage. No matter what type of lighting you are doing having the front wash set up is the most important task.
How many Lux is direct sunlight?
130,000 lux
Illuminance
| Illuminance | Example |
|---|---|
| 300 500 lux | Sunrise or sunset on a clear day. Well-lit office area. |
| 1,000 lux | Overcast day; typical TV studio lighting |
| 10,000 25,000 lux | Full daylight (not direct sun) |
| 32,000 130,000 lux | Direct sunlight |
How many lux equals a lumen?
One lux
Lumens: The total output of visible light from a light source is measured in lumens. Typically, the more lumens a light fixture provides, the brighter it is. One lux is equal to one lumen per square meter (lux = lumens/m2).
