20 square light ceiling, living room led, how many watts?
If it is suction, etc., choose square 400X800 is appropriate. If it's round, suggest 600. And the size of the power, then the living room of the LED lights are generally around 20W on it.
General: the chandelier diameter of not more than 1/4 of the width of the living room (if your living room is 20 square meters, is estimated to be 5 meters X4 meters, so your living room is 4 meters wide, so the lamp diameter of no more than one meter, maintained at about 800 mm in diameter and so on it)
LED energy-saving lamps are usually 3-4 times the number of ordinary daylight lamp, the living room area of 20 square meters, LED bulb to the general power of about 20W, and I hope to help you, I hope to adopt!
