LED Lighting generates more light while consuming less electricity. LED stadium lights have gotten popular in a very short time. The major reason why is because of the savings they offer teams, clubs, and owners of sports venues.
Metal halides have a life expectancy of 12,000 - 20,000 hours while LEDs have a rated life of 50,000 - 100,000 hours. Since LEDs last much longer than metal halide lamps, they are perfect for use in stadiums. They are also very well-built and need very little maintenance during their lifetimes.
LED lights can reduce energy consumption by as much as 90%. Pairing them with lighting controls ensure stadium lights are on only when needed. And if the lights are not used every day of the week, their life expectancy goes up.
Metal halide lights may provide enough lighting to stadiums and sports arenas. But they were never built with today's TV broadcasts in mind. The thing is, a camera does not see light the way a human eye sees it. Modern cameras pick up blue, green, and red spectrums. It mixes these colors to create digital broadcasting.
Lighting that works for fans who are in the stands will not work for fans who are watching the game from home. But most sports venues can't broadcast in ultra HD, even with correct lighting. The lighting systems can't work with 4K or 8K broadcasts. This is another reason why stadiums and sports arenas must embrace LED technology.
Another advantage of LEDs is that they don't flicker. This means they won't affect slow motion replays with a distracting, flashing effect. They improve the game experience
LED lights not only improve the game for the spectators, they also improve it for the players. LED lights were installed at a race track in America. The drivers reported that the light was uniform and that glare had been reduced. Precise pole and fixture placement and advanced lenses ensure that drivers have the best visibility around the racetrack.
When LED lights are installed in a hockey rink or a baseball field, they provide uniform light. This helps the players to see the speed of the hockey puck or the baseball. If metal halide lights are used in these spaces, they create bright and dark spots. As the ball travels through a shadow created by a dark spot, it appears to be slowing down or speeding up. This is a disadvantage to a player who only has a second to determine the position of the ball.
Because sporting activities vary, Their lighting requirements also vary. Games like cricket are quick action with a small playing object and a long viewing distance. They need high light levels. Football and basketball have a bigger ball and a close viewing distance need optimal light levels. The Illuminating Engineering Society gives lighting specifications for different sports and recreational areas. There are also other guides that recommend luminance levels for different sports. Lighting recommendations for different sports are usually grouped into classes of play.
Class I: Top level competition
Class II: Middle level competition
Class III: Low level competition as well as supervised training
The EN 12193:2007 recommends these lighting levels for the major sport arena.
Why are photometrics important? They allow you to see your area and how it would look under LED Lighting taking the risk out of buying. We can easily run different options with our lights, and provide you with the proper information and guidance. We're here to save you money with LED. But it's as important to get the lighting right A Photometric study is designed to analyze the current placement of your lighting fixtures and propose a more practical, efficient or safer solution. Whether you"re looking to optimize security in your parking lot or safety in your factory, a proper review of your lighting placement will identify areas of improvement for maintaining uniform light levels, reducing glare, and highlighting points of interest.
When you request a photometric analysis, you will receive:
The glare rating for all light fixtures used in top level competitions must be 50. Fixtures used in intermediate level competitions must also have a glare rating of 50, except those used in athletics which should have a rating of 55. For lower level competitions, the lights must have a glare rating of 55, except those used in bowls (lawn bowls) which should have a glare rating of 50.
These 8 tips ensure you buy the best LED option.
1. Go For High-Quality LED Chips
High-quality LED chips deliver high brightness, luminous efficacy, and color temperature. The malfunction rate of these chips is very low. We recommend you get LED stadium lights with high-quality, high efficiency LED chips.
2. High Luminous Efficacy
Luminous efficacy is the major indicator of the performance of a LED bulb. It is calculated as the lumens generated for a single watt of electricity pulled. Luminous efficacy measures how well a bulb produces visible light. Which is usually measured in lumens. Thanks to advancements in LED technology, the current luminous efficacy standard is 100 lumens per watt. But, most high-quality LEDs have a higher luminous efficacy than this.
3. The Right Beam Angle
The beam angle usually dictates the distribution of light. If the beam angle is wide and the light uniformity is very high, the brightness on the ground will be very low. But, if the beam angle is narrow, the light uniformity is low. Many dark spots are on the ground despite the brightness of the light.
Choose lights that have the right beam angle balancing light uniformity with brightness. Our lighting engineers can show you by doing a photometric analysis. This will help you choose lights with the right beam angles.
4. The Lights Must Be Waterproof
The longevity and efficiency of light fixtures depends on where you install them. Stadium lights are outdoors and affected by conditions such as water and humidity. This is why they must be designed for wet locations.
Wet locations where water can flow, drip, or splash on the fixtures can affect the components. The light fixtures must be UL Listed for wet locations. They should have an IP rating of 66. IP66 rated lights work well in all weather conditions for stadiums and sports fields.
5. Excellent Heat Dissipation
Heat sinks prevent LED lights from getting damaged because of overheating. Good ones are usually made of pure aluminum which has the best heat conducting rate (238W/mk). The higher the value of the aluminum, the higher its conductivity rate. A good heat dissipation system should provide enough air ventilation passage.
There should be space between each single row of LED chips. The structure should be hollow to reduce air resistance. This helps transfer heat from the lamp to the surrounding area. The heat dissipation section should also be large and dense. Aluminum fins can quicken the cooling process.
6. Color Rendering Index
The color rendering index shows how well colors are seen under a certain light source. It defines how a bulb makes an object appear to human eyes. The higher the color rendering index, the better a bulb’s color rendering ability. When it comes to sports lighting, the color rendering index needs to be 80. In sports like basketball, a CRI of 90 and above is preferred.
7. Color Temperature
Organizations specify the minimum allowable color temperature (correlated color temperature) for sports fields. For instance, FIFA and FIH require their lights to have a CCT of 4000K and above. The NCAA needs lights with a CCT of 3600K and above. While the NFL uses lights with a color temperature of 5600K and above.
Our eyes adapt well to light sources with different color temperatures. Television and digital cameras do not. They must be adjusted to display the colors humans expect to see. This is why it is so important for LED lights in a sports venue to have the proper correlated color temperature. If they don’t, TV cameras will display irritating color shifts as they move across the field.
8. Glare Rating
While the glare rate is seldom mentioned, it is very essential in sports lighting. Too much glare may lead to visual discomfort and cause people to squint as they watch or play a game. It may also impair the vision of details and objects. For example, players may be unable to see fast-moving balls. Glare also reduces the brightness of the light in some areas. Our flood lights have advanced lenses that focus the light beam and decrease light leakage by 50%.
