The pole quantities of led football field light are recommended that: four and six. The four pole rule is that: two poles are located on each side, and not closed to the sideline. A six pole rule is that: three poles are located on each sides and closed to the sidelines.
The sports light will form a illuminated surface through lighting up the lamp, and we called it “beam angle”. If the angle is small, the light uniformity is low and can’t satisfy the need. However, if the angle is larger, the light regularity is higher and cause the waste of lighting. The beam diffusion of led light should project the maximum amount of light onto the football field without generating hot spots. Beam angle must be wide enough to distribute aiming point with an adjacent overlapping.
The minimum installing height of all poles is 50 feet. The installing height can make up extra lumen efficacy by increasing the pole’s height. In order to reduce glare and efficiently use the beam angle of light, the installing height should be increasing at anytime.
