If you want to set the home lighting to avoid wasteful electrical, calculation and careful placement of light points are very important.
The cost and power are two things that usually become attention of the people when setting home lighting for their homes. Before setting for home lighting, the first thing that we need to do is to calculate the allocation of electric power for our home lighting. Allocation amount of electric power for home lighting in a room is influenced by the amount of activity in the room. For example, in a room with 20m² spacious is used for living room and dining room. Electrical power allocation is about 300 watts.
And then, the 300 watts of electric power amount is divided for each space function. Family room and dining room, each of them is received 150 watts of electric power allocation. The electric power had been allocated will be divided again according to the number of light points that are determined to our activity in the room.
After we make the division of power, then we need to create the groups of lights. For a single room, you can use two until three lamps groups. Each of them is controlled with a single switch. For example, one switch control accent lamps, and other switches are made to control the lighting ambience. This grouping of lights will make us easier to control the lights. We can determine which lamps are turned on when the activity remained in the room and which lights should be turned off.
If the activity of the living room is busy activity and all lights in switch on, the electric power used is 150 watts. You need to seek power which is spent on home lighting in the dining room is lower, for example 50 watts. This can be done by turning off some of the lights that are unnecessary, such as accent lights. Vice versa, if in the dining room activity is high, you should turn off lights that are not needed in the family room.
What you must do if the activity in the second room is busy too? You must keep the electric power in order not to spend the entire allocation of electric power. For example, you can make the allocation of home lighting that balanced with 100 watts of each power. You can turn off the unnecessary lights group. With those methods, you can avoid wasteful electrical for your home lighting.
