The wattage of LED lights required in a living room depends on the level of brightness desired and the specific LED light fixture being used. As a general guideline, the recommended wattage per square foot for LED lighting in a living room is approximately 1.5 to 2 watts.
For example, if your living room is 150 square feet, you would need approximately 225 to 300 watts of LED lighting (150 square feet x 1.5 to 2 watts per square foot).
However, it’s important to note that wattage is not always the most accurate measure of the brightness of LED lights. Instead, the brightness of LED lights is typically measured in lumens. Therefore, you may want to consider the lumens of the LED lights you are considering, and choose a fixture with an appropriate brightness level for your living room. For general lighting in a living room, a range of 5000 to 7000 lumens is typically suitable.
