What are the best stadium lights available? Why should we consider replacing metal halide, halogen, high-pressure sodium (HPS), and mercury lamps with LEDs? What factors are crucial when selecting lighting for a football field? This article will provide insights into illuminating outdoor football fields to meet the high standards of events like the FIFA World Cup, Olympic Games, Premier League, and UEFA competitions using LED technology.
As you prepare documentation and products for a lighting tender, focusing on key factors is essential for success. The primary considerations include the requirements for lighting fixtures, such as lux levels (brightness) and uniformity.
There are various regulations governing stadium lighting. According to UEFA’s lighting guide, football fields are categorized into six levels: Elite Level A for Europa League finals, Level A for Super Cup finals, Level B for semi-final matches, and Level C for qualifying rounds, among others. The lighting standards escalate with the significance and prestige of the matches, with the highest standards reserved for the final.
Brightness of Football Fields
Effective lighting for football fields is comprised of two key components: horizontal and vertical luminance. Horizontal luminance refers to the level of light that covers the playing surface, while vertical luminance pertains to the illumination of the players’ portraits and surroundings. According to industry standards, a football stadium should achieve a horizontal luminance of 2000 lux and a vertical luminance of 1500 lux. To meet these demanding specifications, it is typically necessary to deploy hundreds of high-power LED flood lights. These powerful lights ensure that the field is uniformly lit, providing optimal visibility for both players and spectators. The extensive coverage ensures that the lighting quality remains consistent across the entire field, facilitating excellent performance and clear viewing experiences.
Lighting Uniformity
Uniformity is another critical aspect of stadium lighting, with UEFA guidelines stipulating a uniformity ratio between 0.5 and 0.7. This ratio, which ranges from 0 to 1, measures how evenly light is distributed across the field. High uniformity is crucial because uneven lighting can lead to visual discomfort and eye strain for players and spectators alike. Achieving this level of uniformity can be challenging due to the inherent nature of light distribution, where spots are typically circular or rectangular and can overlap or leave gaps. To address this, we utilize advanced techniques such as employing LED lights with smaller beam angles and lower power outputs. Additionally, our asymmetric lighting design enhances light distribution, ensuring more consistent coverage. These methods are particularly important for high-profile events like the Premier League and the Olympic Games, where precise lighting is essential.

Considerations for Luminaire Height
The height at which luminaires are installed in stadiums typically ranges from 30 to 50 meters. This height poses unique challenges for maintaining optimal lighting conditions on the football field. One significant issue is light loss, which is an inherent part of current lighting technology. Despite advanced photometric designs, it is impossible to direct 100% of the light beam to the field. Approximately 30% of the emitted lumen is scattered to the surrounding areas. To address this challenge, two primary strategies are employed: improving optics and increasing the number of lighting fixtures.
Using Better Optics
One effective method to minimize light loss is to utilize high-quality optics. By adopting advanced LED chips and lens covers, the concentration of the light beam is improved, which helps to reduce brightness loss. However, this approach has limitations. When using such optics across an entire football pitch, uniformity can be compromised. The result can be numerous overlapping circular light spots, which may lead to uneven illumination. To achieve a balanced lighting solution, a comprehensive photometric design is essential. Our engineering team is prepared to assist with this process. For a tailored solution, simply fill out our form for prompt support and guidance.
Increasing the Number of Lighting Fixtures
Another approach to counteract lumen depreciation is to increase the number of lighting fixtures installed on the stadium ceiling. For instance, if the theoretical power requirement is calculated to be 10,000 watts, it may be necessary to install 12,000 to 13,000 watts worth of floodlights to achieve the desired lighting outcome. This method helps to ensure that the field receives adequate illumination despite the inherent losses in light output.
Power of LED Lights Required
Calculating the Total Power Needed
Determining the total power required for stadium lighting involves precise calculations. For example, consider a standard football field measuring 105 meters by 68 meters. The total area of the field is 7,140 square meters. To achieve the required illumination of 2,000 lux across this area, the total luminous output needed is 14,280,000 lumens. With our LED floodlights offering a luminous efficiency of 140 lumens per watt, the theoretical minimum power required is calculated by dividing the total lumens by the efficiency, which amounts to 102,000 watts.
However, this theoretical value does not account for light loss and the height of the luminaires, which must also be considered. When these factors are included, the practical power requirement is approximately 150,000 watts. This highlights the importance of accurate lighting simulations to ensure adequate illumination.
Comparing with Metal Halide Lamps
If the stadium currently uses metal halide lamps, the power requirements will be significantly higher due to their lower lighting efficiency of approximately 70 lumens per watt. For the same football field, the power required would be around 300,000 watts. This comparison underscores the energy-saving benefits of switching to LED lighting, which can lead to substantial reductions in both energy consumption and electricity bills.
