Football is one of the most popular sports in the world. There are enthusiastic fans in every corner of the world. With more and more participants and people watching the game, the requirements for lights for football field are getting higher and higher. Lighting equipment must ensure that athletes and referees can clearly see what is happening on the playing field. All activities and scenes enable them to achieve their best performance, and spectators must also pay close attention to the athletes and the game in a comfortable and pleasant environment. The lighting design of the stadium must not only meet the needs of all kinds of personnel on site, but also provide high-quality TV broadcast scenes for the majority of TV audiences. So, what kind of light is most suitable for a football field? You may find the answer after reading this article.
Different field of view size and illumination requirements lead to different wattages of the lamps used. Generally, a standard football field needs 1000W LED lights to meet the illumination requirements. For a small entertainment football field, 300W to 500W is sufficient.
The football field is divided into an indoor football field and an outdoor football field. Outdoor (indoor) football field illumination standards are divided into: training and entertainment activities illuminance 200lx (300lx), amateur games 300lx (500lx), professional games 500lx (750lx), ordinary TV broadcast 1000lx (1000lx), 1400lx (14) large-scale international competitions High-definition TV broadcast, 1000lx (750lx) TV emergency.
What are common football field sizes?
Futsal football matches are rectangular, 25-42m long and 15-25m wide. In any case, the area of the international competition venue should be: length 38 ~ 42m, width 18 ~ 22m. Need 300W-1000W sports lights.
The size of the 7-a-side football field: 65-68m in length and 45-48m in width. Need 500-1000W sports lights.
The size of the 11-a-side football field is 90-120m in length and 45-90m in width; the standard length for international competitions is 105-110m and the width is 68-75m. Need 1000W LED sports light.

What are advanced features of our lights for football field?
1. Update optics
As sports lighting requirements become more and more stringent, our lighting quality has also improved accordingly. Using our 5th generation optical lens, energy efficiency, effective ground reach lumens, anti-glare and anti-flicker capabilities have been increased by 30%. For fast sports involving players’ strenuous exercise and football, we believe that our new generation of lighting equipment is most suitable for all outdoor and indoor games.
2. Advanced thermal control
High temperature resistant outdoor stadium lights
Our third-generation integrated heat dissipation system consists of an enlarged LED base plate and densely extending fins. The system reduces the junction temperature by effectively conducting heat from the source (LED chip) to the circular aluminum heat sink structure. Reduce the temperature inside the lamp body and the optical lens, so as to protect the light well. This is the reason why our stadium LED lighting works more than 85,000 hours.
3. Bright LED packaging technology
Gold Wire Free Packaging is only found in high-end LED products. We use this amazing technology because it can further improve the efficiency and life of LEDs. In addition, we upgraded the key materials in the packaging to provide further insurance.
4. Lightweight LED lights
Lighter lamps can reduce your installation costs and time. Our LEDs are lighter than other LEDs because these lights are designed for football fields. Our engineers constantly modify the design to make the lamps more compact. Whether it is a new installation or replacement of an old lamp, our products are easier to install.
5. High-quality lights
Quality stadium lighting supports 4K broadcast requirements
Our LED stadium light has excellent CRI and TLCI> 90 colors, wide color temperature from 5000 to 7000K, select high-purity lights, stable DC output power supply to ensure <0.3% flicker rate. All these features make our lighting solutions suitable for general sports, professional sports and broadcasting, and high-speed camera broadcasting.
6. Environmentally friendly and safe materials
Our lights for football field are made of die-cast aluminum. In addition, our lamps use polycarbonate instead of acrylic optical lenses, and 304/316 stainless steel screws and brackets instead of galvanized iron alloy materials. Unlike metal halide lamps or mercury lamps, our LEDs do not contain toxic chemicals such as lead and mercury, making them safer and more practical to use.
Lights for Football Field: Buyer’s Guide 2022
What is the best stadium light? Why do metal halide lamps, halogen lamps, high-pressure sodium lamps and mercury lamps need to be replaced with LEDs? What are the factors to consider when buying lights for football field?
It is exciting to start preparing documents and products for the lighting tender. In order to increase the chance of success, the first reminder we need to consider is the requirements of the lighting equipment, including lux (brightness) and uniformity.
1. The brightness of the football field
The lighting is divided into two parts: horizontal brightness and vertical brightness. The horizontal direction is the light covering the entire court, and the vertical direction is the portrait of the player. The document stipulates that the lighting level of the stadium should be 2000 lux, and the vertical should be 1500 lux. For this setup, we will need hundreds of sets of high-power LED floodlights.
2. Illumination uniformity
UEFA also requires stadium lighting to have a uniformity of 0.5 to 0.7. This parameter is based on a ratio of 0 to 1 and indicates the degree to which the brightness is evenly distributed. This is an important consideration because uneven light can irritate the eyes of players and spectators. In fact, it is not an easy task to achieve high uniformity, because we can imagine that the light spot is circular (or often rectangular), with overlapping and non-overlapping areas. One of the technologies we use is to use LED lights with a smaller beam angle and lower power. Asymmetrical design can improve lighting distribution. We provide LED lights for international competitions such as the Premier League and the Olympic Games.
3. TV broadcast compatibility
This is a new era of 4K TV broadcasting. The uniform and high-quality vertical brightness on the LED floodlight can achieve high standard photo and video production. Therefore, we also strive to reduce the glare of the lamps. The anti-glare optics in our LED lights will not give players and spectators flicker and glare. This technology is achieved through a special lens cover and coating, which can suppress unwanted glare while maintaining brightness.
4. Stadium roof height
The height of the lamp is generally within 30-50 meters; therefore, we need good LED lighting without much loss of brightness. In fact, with today’s technology, light loss is sometimes inevitable, because no matter how precise your photometric design is, not all light beams are 100% projected onto the football field. On the contrary, part of the lumen (about 30%) is scattered around. In order to solve this problem, we have two methods.
a) Use better optics
With high-quality LED chips and lens caps, the beam is more concentrated, reducing brightness loss; however, the limitation is that we cannot use these lights on the entire football field because the uniformity will be reduced-imagine there are countless circular spots on the ground. Therefore, it is necessary to achieve a good balance through a comprehensive photometric design. Our engineers are happy to help. By filling out our form, you can always get a timely response.
b) Increase the number of lamps used
Installing more floodlights on the ceiling of the stadium to prevent lumen decay is a relatively passive way. For example, if the theoretical (calculated) value is 10,000 watts, we will eventually need at least 12,000 to 13,000 watts to get the best results.
5. Required LED light power
Quickly understand the total power required by the football field lights. We can perform the following calculations. Take the traditional 105m*68m football field as an example. A lawn of 7140 square meters requires 7140 * 2000 Lux = 14,280,000 lumens. What does it mean? Since the luminous efficiency of our stadium floodlight is 140 lm/W, the minimum wattage of the LED should be 14,280,000 / 140 = 102,000 watts. This is the theoretical minimum we need, because we also need to consider the light loss and the height of the luminaire mentioned above. Before the computer lighting simulation, we will know that the required power is about 150,000 watts.
Having said that, you may ask, what will happen if I use metal halide lamps to illuminate the football field? This answer is to double the power required! Since the luminous efficiency of metal halides is about 70 lm/W, the required power is about 300,000 watts. Therefore, replacing stadium lights with metal halides can save a lot of energy, thereby saving electricity bills.
6. Light pollution in stadiums
The top lighting of the stadium must not cause light pollution. Due to light leakage, neighboring residential areas were seriously affected. In 2017, there were repeated incidents related to this issue in Michigan, the United States. The NFL stadium in Detroit uses very high power lighting. However, there is considerable light scattering outside the venue. Some people even complained that when the house is 5 kilometers away from the competition venue, the lights are very exciting and seriously affect sleep. The safety of road users is also negatively affected.
In fact, the brightness of the ground around the arena should not exceed 25 to 30 lux. It has become one of the lighting requirements.
About 45% of football stadiums in the United States still use traditional light sources, such as metal halide, HPS and HID lights. Although the efficiency of MH lamps has been improved from time to time, it is still significantly inferior to LED lamps. Today, the efficiency of LEDs has increased to 140 lm/W, while MH is about 75 lm/W. In addition to the lights for the new arena, we also provide high-quality LEDs to replace the metal halide of the football stadium lights.
7. Longer service life
By transforming metal halides into LED lamps, the service life of the lamps has been greatly increased to 80,000 hours. If the lights are turned on for 8 hours a day, our products can be used for at least 25 years without a significant drop in brightness. Due to its solid-state characteristics, LEDs are also considered a durable lamp. Our modified lighting products do not contain precision parts such as surface welding and gold wires.
8. Good heat dissipation system
Another reason for the high durability is that our football stadium LED lights have a very good heat dissipation system. In fact, if heat continues to accumulate around the LED chip, it will reduce brightness and life; therefore, we also attach great importance to improving the heat sink to reduce the junction temperature of the lamp to achieve long-term operation. Usually, it is achieved by aluminum extension fins that contain large circular arrays with large surface areas.
9. Durability of floodlights
After the stadium lighting is replaced with metal halides, we can provide stronger materials for the lamps. This is because our LED lights are made of polycarbonate and high-quality aluminum alloy. The material is corrosion resistant, so it is unlikely to be damaged during normal use. In addition, our products have IP66 waterproof certification. It can withstand heavy rains and general water splashes.
According to our experience, LED companies usually provide a warranty period of 1 to 5 years. We offer a warranty of 5 years. Why not choose a longer shelf life so that you can get fast support from the company at any time.
