LEDS don’t produce heat as infrared (IR) radiation. The bulb and surrounding area of an LED bulb aren’t hot to the touch. Stadiums benefit from this because of the high volume of people and the surrounding environment. Proper heat dissipation in an LED stadium light is crucial. Without it, the LED light will die and lose certain characteristics. These include: Forward voltage Lumen output Output wavelength Lifetime of light Choosing a light with proper heat dissipation ensures the bulb will last longer than a high-pressure sodium or metal halide bulb.
