How many watts per square meter do LED billboard lights have?

This question is difficult to answer accurately. First, you must determine the model of your LED screen. Take the common P10 outdoor full-color, the power of the LED screen is close to 1000~1200W/square. If the efficiency of the switching power supply is 80% (a parameter that is often ignored, some power supplies have a large starting current), the input power is is 1200/0.8=1500W! . On the basis of this value, some margin should be added to ensure the safety of the power-on system. Therefore, a balanced selection parameter design should be carried out while ensuring safety and margin.

The wattage of the LED lamp must be determined according to the area, so as to achieve lighting. Next, the editor will bring you a LED lamp wattage area comparison table. For your reference.
