Arena Lighting Calculator: A Comprehensive Guide

As the name suggests, an arena lighting calculator is a tool that helps you calculate the amount of lighting required for a particular arena or space. It takes into account various factors such as the size of the space, the type of activity that will take place, and the desired level of illumination. In this comprehensive guide, we will discuss everything you need to know about arena lighting calculators.

Arena Lighting Calculator: A Comprehensive Guide

Why do you need an arena lighting calculator?

An arena lighting calculator can help you determine how much lighting is required for a specific space or activity. This is important because inadequate lighting can negatively affect performance and safety. For example, if you’re playing basketball in a poorly lit gymnasium, it may be difficult to see the ball or judge distances accurately. Similarly, if you’re working in a factory with insufficient light, it could lead to accidents and injuries. An arena lighting calculator ensures that you have enough light to perform your tasks safely and efficiently.

Factors to consider when using an arena lighting calculator

When using an arena lighting calculator, there are several factors that you need to consider:

  • Space size: The size of the area will determine how many lights are needed.

  • Desired illumination level: The level of illumination needed depends on the activity taking place in the space. For example, a basketball court may require more light than a dance studio.

  • Light fixtures: Different types of fixtures provide different levels of illumination. You’ll need to choose fixtures that provide enough light for your needs.

  • Ceiling height: The height of the ceiling affects how far apart the lights should be placed.

  • Reflectivity of walls and flooring: The materials used on walls and flooring can affect how much light is reflected back into the room.

These factors must be taken into account when using an arena lighting calculator to ensure accurate results.

How does an arena lighting calculator work?

An arena lighting calculator works by taking into account the factors discussed above to determine how much light is needed for a particular space. It uses a formula that takes into account the surface area of the space, the desired illumination level, and the efficiency of the light fixtures.

Here’s an example:

Let’s say you have a basketball court that measures 50 feet by 94 feet with a ceiling height of 20 feet. You want to achieve an illumination level of 75 foot candles (fc). You’ve chosen LED fixtures with an efficiency rating of 100 lumens per watt.

To calculate how many fixtures you need, you can use the following formula:

(Number of Fixtures) = (Total Lumens Required) / (Lumens per Fixture)

To calculate the total lumens required, use this formula:

(Total Lumens Required) = (Surface Area) x (Illumination Level)

First, calculate the surface area:

(Surface Area) = (Length) x (Width)

(Surface Area) = 50 ft x 94 ft

(Surface Area) = 4,700 sqft

Now, calculate the total lumens required:

(Total Lumens Required) = (Surface Area) x (Illumination Level)

(Total Lumens Required) = 4,700 sqft x 75 fc

(Total Lumens Required) = 352,500 lm

Finally, calculate the number of fixtures needed:

(Number of Fixtures) = (Total Lumens Required) / (Lumens per Fixture)

(Lumens per Fixture) = (Fixture Efficiency Rating in Lumens per Watt ) x Watts

We know that we’re using LED fixtures with an efficiency rating of 100 lumens per watt. Let’s assume each fixture has a power rating of 400 watts.

(Lumens per Fixture)=100 lumens/watt X 400 watts=40,000lumens/fixture

(Number of Fixtures) = (Total Lumens Required) / (Lumens per Fixture)

(Number of Fixtures) = 352,500 lm / 40,000 lm/fixture

(Number of Fixtures) = 8.81 fixtures

Since we cannot have a fraction of a fixture, we round up to the nearest whole number. So in this case, we would need nine fixtures.


An arena lighting calculator is an important tool for ensuring that a space has adequate lighting for its intended use. By taking into account the size of the space, desired illumination level, and other factors, a lighting calculator can determine how many lights are needed and which types of light fixtures are best suited for the job.

By following these guidelines and using an arena lighting calculator, you can ensure that your space has the appropriate level of illumination to keep people safe and productive.


What is an arena lighting calculator?

An arena lighting calculator is a tool used to determine the appropriate type, quantity, and distribution of lights needed to achieve optimal illumination in an indoor or outdoor sports facility.

Why is it important to use an arena lighting calculator?

Using an arena lighting calculator ensures that you have the right amount and type of lighting necessary for a safe and enjoyable experience for both spectators and athletes. It also helps save on energy costs by avoiding over-lighting or under-lighting the space.

How do you use an arena lighting calculator?

An arena lighting calculator will typically ask for information such as the size and height of the facility, the type of sport being played, and any specific lighting requirements. Using this information, the calculator will recommend the necessary number of fixtures, lumens, and beam angles required for optimal illumination.

Can you use an arena lighting calculator for outdoor facilities?

Yes, an arena lighting calculator can be used for both indoor and outdoor sports facilities. It takes into account factors such as ambient light, weather conditions, and glare from surrounding buildings in order to provide accurate recommendations.

What are some common mistakes made when choosing arena lighting?

Common mistakes include not accounting for different types of sports activities that take place in the facility; using incorrect light levels which affect player performance; poor placement or spacing of lamps; and overlooking required protection against excessive glare caused by reflection off shiny surfaces or windows.

What are some benefits of using LED lights in arenas?

LED lights last longer than traditional metal halide bulbs, reduce energy consumption up to 50%, generate less heat which prolongs lamp life expectancy; and are more environmentally friendly by reducing CO2 emissions with no toxic substances or mercury waste disposal costs associated with them.

Can you install arena lighting by yourself?

It is not recommended for the average person to install arena lighting. An experienced electrician or lighting professional should be consulted to ensure proper installation and wiring, and adherence to safety codes and regulations.

What is the difference between foot candles and lux when it comes to arena lighting?

Foot candles are a unit of measurement used in the United States to describe light levels, while lux is used internationally. One foot candle is roughly equivalent to 10 lux. This means that if an arena has a recommended minimum of 1000 lux, the equivalent measurement in foot candles would be approximately 100 fc.

How do you calculate uniformity ratio for arena lighting?

Uniformity ratio is calculated by dividing the minimum illuminance level in an area by the average illuminance level. For example, if an area has a minimum of 400 lux and an average of 800 lux, then the uniformity ratio would be 0.5 (400 ÷ 800 = 0.5). The goal is usually to achieve a uniformity ratio of at least 0.7 for sports facilities where accurate visual assessment is required such as basketball or tennis courts; while other activities like ice hockey may require lower ratios because illumination levels vary depending on position due to changing play patterns.

Can LED lights affect athletes’ performance?

Successfully designed LED systems can improve a player’s ability to see detail, detect motion more accurately, track objects better with less flicker-inducing glare than conventional HID lamps when certain criteria are met such as selecting high color temperatures (5000K or higher) with high color rendering indices (=90+), adequate vertical footcandle (fc) levels on task area at least one meter above finished floor level measured horizontally upstage center stage downstage using a calibrated light meter with cosine correction etc. This might result in improved reaction time, reduced errors, and faster decision making.
