Not all floodlights are the same. How to choose a spotlight that can provide excellent lighting and save energy.
From the Lumens,PIR,Beam Angle,Color Temperature,Waterproof those factors.
Lumens: Measure the brightness of a light. —The more higher lumen the brighter of light. When choosing a Led Stadium flood light, the larger lumens is the better.For example,SED
1000w Outdoor Led Stadium Flood Light has 150000lm.Each watt has 150 to 170lm/w.
PIR: This stands for passive infrared receiver. It means that the floodlight is activated when motion is detected.When no person the light is off,when the person come the led flood light light on automationly.
Beam angle: The angle at which the light is distributed—the wider the angle, the more area is covered by light.Diffierent sports field need diffierent beam angle.
Colour temperature: Measured in Kelvin (k) from ‘warm’ to ‘cool’—the higher the number of Kelvin the cooler the light. If you are choosing floodlights to illuminate garden features you may want to choose a warmer, more welcoming colour temperature with a low Kelvin rating, such as a warm white. A cooler white with a higher Kelvin rating provides a crisper light, ideal for practical or security purposes.From 2700K to 7000k.
