One of the primary advantages of uniform lighting is that it eliminates shadows and dark spots on the playing surface. By providing consistent illumination, athletes can accurately perceive the movement of the ball, players, and other objects, leading to improved performance and reduced risk of injury. Additionally, uniform lighting enhances the viewing experience for spectators, allowing them to follow the action seamlessly without any distractions or visual inconsistencies.To achieve uniform lighting, several key considerations need to be addressed during the design process. These include selecting the right LED fixtures, positioning them strategically, and properly configuring the lighting layout. Most optical designer indeed know that the higher poles, the greater uniformity, and more lamps with smaller power, the better uniformity.For example, Romanso have designed a stadium lighting project of the FIFA Grade A for one of our customers in August, 2023. We designed two solutions for 28m height and 36m for customer's comparison. The result you can image? Same quantities and same power of LED sports light for a same project, but different lighting effects and uniformity for different heights. We can see from the pictures below, the lighting effects and uniformity of 36m height are much better and the 28m.

Secondly, let's talk about the color and visual perception of stadium lighting with high glare energy and glare hazards. The stadium lighting with high glare energy is intuitively manifested as high color temperature, more blue light, and a light color that leans towards cyan.

When the color temperature of the lamp body is 6500K, the proportion of visible light will decrease, and the glare energy will be higher. The color of the lamp surface is cold white light. Although the light is white and bright, there is a sense of coldness and warmth in the vision. When looking directly at the surface of the lamp body, there is no obvious tingling sensation in the light, but there is a noticeable discomfort. When the eyes leave the surface of the lamp body, although there is no obvious visual black phenomenon, there is an instantaneous "visual flower" phenomenon, and then the visual sense can be normal.

This type of stadium lighting does not have a significant amount of glare energy and poses a risk of glare, which is not serious. However, the degree of harm caused by glare cannot be ignored. Used for venue lighting, players may tolerate the level of glare hazards but may experience visual discomfort. To some extent, it will affect the operational efficiency of sports venues.

When the color temperature of the lamp body is 6800K, some companies will further increase the color temperature to 6700K -6800K in order to pursue the surface brightness of the stadium lights. High-color temperature venue lighting significantly reduces visible light energy and increases the proportion of glare energy, resulting in high glare energy. The light color of the lamp body is not bright white, but rather slightly blue. Looking directly at the surface of the lamp, the light is harsh and the visual pain is obvious. When the eyes leave the surface of the lamp body, there is obvious visual blackness, and the time for visual restoration to normal is also relatively long.

This type of stadium light has high glare energy and poses great harm to glare. If used for venue lighting, the level of glare harm to players is usually unacceptable and intolerable. It will seriously affect the operation of sports venues.
