Types of light sources
The stream of light is the main characteristic that determines how much the light source burns. The fact is that the efficiency of lamps can be different and different types. Incandescent lamps are the most common in our country. They display warm and soft light, which perceives human vision well. It is best to use chandeliers with incandescent lamps in bedrooms and living rooms. But these light bulbs are a lack — their efficiency is in the region of five percent. That is, only 5 percent of energy is spent on the light, and the other goes to the heating of the room. However, these shortcomings are compensated by the simplicity of the type and low cost.
