Horizontal Lux Requirements
Horizontal lux refers to the light levels that illuminate the playing field horizontally. The goal of horizontal lux is to ensure that players can clearly see the ball, other players, and the field markings, without shadows or dark spots interfering with the gameplay. Horizontal lighting is critical for maintaining the visibility of the entire pitch, as well as ensuring optimal conditions for television production.
For the Premier League, the minimum horizontal lux requirement is generally 1,500 lux, as set by international sports governing bodies, including FIFA. However, for high-definition broadcast quality, this requirement is often exceeded, and many stadiums in the Premier League aim for lux levels ranging from 2,000 to 2,500 lux. This higher illuminance ensures that every detail of the match is visible, from the players’ movements to the ball’s trajectory. Broadcast quality is essential for the Premier League, as matches are viewed globally on various platforms, including HDTV and ultra-high-definition (UHD).
The increase in lux levels required for broadcasting is part of the global push for enhanced viewing experiences, where HD and UHD technology require higher-quality lighting to capture the crisp details of the match. The FIFA World Cup standards, for example, require 2,000 lux for general play and 2,500 lux for HD broadcast. Many Premier League stadiums have adopted these figures to ensure the highest production standards.
Vertical Lux Requirements
While horizontal lux deals with illuminating the pitch’s surface, vertical lux addresses the light required to properly illuminate the vertical surfaces of the stadium, including the players, the goalposts, and the spectators in the stands. Vertical lux is particularly important for capturing the details of the players’ movements, such as facial expressions, ball control, and aerial duels, which are especially important for broadcasting.
The typical vertical lux required for Premier League stadiums is between 500 and 800 lux, depending on the specific venue and lighting setup. This range is sufficient to highlight the players’ movements and uniforms, ensuring that they are clearly visible to both fans in the stadium and the viewers watching the match.
In contrast to horizontal lux, which is focused on the illumination of the playing field, vertical lux is more concerned with visibility at the human scale. For example, when a player heads the ball or performs a skill move, proper vertical lighting ensures that the audience can fully appreciate the athleticism involved. Additionally, vertical lux can also be used to highlight key features of the stadium and its environment, such as crowd reactions or sponsor logos.
A Detailed Comparison of Horizontal and Vertical Lighting
Both horizontal and vertical lighting serve distinct yet complementary functions in a stadium. While horizontal lux illuminates the playing field, vertical lux provides clarity for everything above the field—whether that’s the players’ actions, the goalposts, or the surrounding environment.
Horizontal vs. Vertical Lighting in Practice
When comparing horizontal and vertical lux, one key difference lies in the spatial distribution of light. Horizontal lighting is more about uniformity and ensuring that the entire pitch is evenly lit, which is crucial for creating consistent playing conditions across the whole field. This even distribution allows the players to track the ball in any part of the pitch without experiencing shadows or inconsistencies in light intensity. The higher the horizontal lux level, the better the clarity of the entire field, which is important for both the athletes and broadcasters.
Vertical lighting, on the other hand, is essential for detailed views of player actions, making sure that the audience can easily see the nuances of the game such as precise passes, tackles, or shots. It’s the component of lighting that allows viewers to see individual players clearly, especially during aerial or skillful moments.
Thus, the difference between horizontal and vertical lighting lies in their focus: horizontal lux is about providing general field illumination for gameplay, while vertical lux highlights the players and crowd, ensuring that the action is captured effectively on camera and easily perceived by fans in the stadium. Both types of lighting are integral to providing the best possible matchday experience.
