A football field's lighting system is crucial to everyone's schedule. According to FIFA standards, the length of the soccer field for international competitions is 100-110 meters, the width is 64-75 meters, and there shall be no obstacles within 5 meters of the bottom line and sidelines to protect the safety of the participants.
For the World Cup finals, the dimensions are 105m in length and 68m in breadth.
The usual football pitch is 90-120 meters in length and 45-90 meters in width.

Football stadium lighting is not as straightforward as it may seem. It is separated into three categories, which according to the EN12193 international standards are excellent.
Football field lighting refers to the lights used to illuminate a football field. Typically erected at 70 feet, they may reach heights of up to 250 feet over the playing field in major stadiums. Currently, they are mostly LED-based for great efficiency and use high-end narrow beam optics to illuminate the ground without creating glare.
Brighter Lights, Less Energy Consumption, and Vivid and consistent lighting is necessary for viewing a football game, and LED light provides the brightest illumination. Something to carefully note is that lumens and watts are not the same. By simple definition, a lumen is the brightness of the light emitted. Watt is the amount of energy used to create light. An LED light produces a significantly greater amount of light (lumens) when compared to a traditional light source of the same wattage.
For example, if you compare 1500-watt sports lighter to a 500-watt LED stadium light, the difference in the brightness of light produced is staggering. The LED light produces more lumens than the traditional HID bulb but saves 1000watts each. Though your initial investment may be slightly more for LED lighting for your football field, you will save money due to less energy consumption and still have the vivid and uniform illumination that is necessary for the viewing of a game.
The Importance of Beam Angles
Uniformity and brightness are of utmost importance on any sports field, including the football field. This can be achieved by installing LED football field lights with a combination of correct beam angles. It is crucial to remember that the higher up the lights are to be installed, the narrower the cone should be to ensure you get the best lighting for your field. LED lights are smaller and require less maintenance and are therefore ideal when lighting needs to be placed at a greater height.
The first thing to consider if you are interested in LED football field lighting is will the installation be for an existing field or a new field. If you are installing lights on a current field, take into account installed fixtures such as high-mast poles. Working within your organization’s budget may require you to use these fixtures or limit you to the amount or type of poles, etc. you can acquire. On the other end of the spectrum, if you are lighting a new football field, you have options as to the placement of poles which allow for better design options. This is where a photometric study will be invaluable.
Photometric Study
A photometric study specifically determines how a light leaves a fixture and illuminates its surrounding area. It is imperative to have this done to take any guesswork out of your lighting needs. When having a photometric study conducted on a football field, engineers review the size of the entire field and then they make a note of the number, location, and height of the light poles. They also take into account uniformity and illuminance levels. They will use all of this information to design the lighting needed for the football field. This detailed study will ensure you meet any requirements set forth by football league regulations for any competitive level and any neighborhood ordinances. Photometric studies are done through the use of a computer program and are generally completed by an engineer. The study also allows not only for lighting needs but also for electrical requirements and cost estimation.
LED Lighting is of Excellent Quality
Based on a number of elements, LED football field lighting is of high quality overall. On the field, glare reduction may avoid accidents and mishaps. Poor illumination results in blinding glare, which may lead to dropped passes, inaccurate throws, and even missed sideline signals. Reducing glare may also improve the comfort of watching a game. Anti-glare and uniform lighting may greatly improve the game for all spectators, players, coaches, and other individuals present. The absence of shadows and dark areas is provided by uniform lighting, which improves broadcasting, photography, and replays on the big screen (if there is one). This also makes the playing area safer.
In addition to minimal harmonic distortion and CRI scores over 70, high-quality LED lighting also has two further key characteristics: Total Harmonic Distortion (THD) is the impact of all electrically powered devices on the power system. Low-harmonic-distortion LED football field illumination has a negligible influence on the power system in its region. CRI (Color Rendering Index) is a measure of how a certain light source renders color changes (hues of the same color). A higher CRI score indicates that the illumination enables the human eye to distinguish more variations. LED football field illumination with CRI ratings of 70 or more.
