    The light efficiency of LED lights is higher, you can choose to compound tile per square meter for reference, 40 square meters may need 60-80W LED lights.

    The total power of LED bulbs is generally about 20W, and if it is 5W, it should be at least 4.

    The luminous efficiency of the LED lamp itself is relatively high, the luminous efficiency of the light reaches more than 100 lumens watts, the ordinary incandescent lamp can only reach 40 lumens watts, and the energy-saving lamp hovers around 70 lumens watts. Therefore, with the same wattage, the LED lamp effect will be much brighter than incandescent lamps and energy-saving lamps. The brightness of a 1 watt LED lamp is equivalent to about 2 watts of energy-saving lamp.
