How many watts should I use for lighting in a room?
Home decoration, interior lighting design is an indispensable part of it. Many people think that lighting design is very simple, just choose a few lights and it's OK. Let's not discuss whether this approach is right or not. If you really do it, then what brightness should be used for lamps or light sources in the living room, bedroom, kitchen, bathroom, etc., or how many W should be used? Woolen cloth?
Home lighting design
Here, we do not discuss the topics of technology and art, but only make the following suggestions for the selection of the wattage of lamps in each room of the home (taking LED light sources as an example):
Living room: 1 square meter needs about 1.7W, 15 square meters living room needs about 25W light source for lighting, other space algorithms are the same.
Living room lighting
Kitchen: about 1.7W per square meter (such as spotlights in the operation area, cupboard light strips and other auxiliary lighting are not within the scope of this article)
Dining table chandelier: According to the normal size of the dining table, about 8W lamps are needed. If there is a diffuser, the power needs to be increased by 5W. Of course, if your home is very rich, it is OK to double the power.
Restaurant lighting
Lights under the kitchen cabinet: The console is above 1m and below 2m. If you use light strips or light tubes, then 1m or so, about 5W of power is enough, and it can be deduced if it exceeds two meters.
Bedroom: Compared with other rooms, the brightness requirements of the bedroom are lower, 1 square meter with 1W is enough, of course, if you like to read on the bed, then a bedside lamp with a light source of 5W is also enough.
Bedroom lighting
Bathroom: about 1.7W per 1㎡
PS: Regarding table lamps and floor lamps, no matter which room you place them in, we believe that 5~10W light source is sufficient.

Finally, let me explain again, the above brightness matching is based on LED light source as an example. If the light source of the lamp you choose is an energy-saving lamp, multiply the wattage by 2 on the basis of the above (take the living room of 15 square meters as an example, the LED light source needs 25W, and the energy-saving light source needs 50W); if your lamp light source is For incandescent lamps, multiply the wattage by 6, and the algorithm is the same as before.

The above calculation result is an ideal value, and the choice of light source cannot be just that precise. When purchasing a light source, we should just follow this reference range. If you have high requirements for brightness, or the lampshade has strong shading, you can increase the wattage by about 30% proportionally on this basis.
