Is spending on energy-saving lamps justified? On the one hand, they save energy. On the other - is it really so? Lighting plays an important role in the life of every person, it is necessary both for comfortable living and for work. Depending on the needs, most people prefer incandescent lamps with different capacities (40 W, 60 W, 100 W). From the course of school physics, it is known that the efficiency of an ordinary lamp is only 50%, the other half of the energy goes into heating the lamp.
An energy-saving lamp works with the participation of a phosphor - a special substance that forms visible light under the influence of ultraviolet radiation.
Pros of an Energy Saving Lamp
Here we consider the advantages of purchasing energy-saving lamps:
- Due to the features of the phosphor, it is possible to choose lighting of different colors. This expands the possibilities of giving an individual style to the room;
- Due to the larger area of illumination, the light spreads more smoothly without straining the eye. Some people find it difficult to get used to such a light; therefore, for starters, it is worth choosing lamps with warm daylight;
- This is a great option for chandeliers where the lamps fit close to the decorative elements. Energy-saving lamps practically do not emit heat, so you can not worry about the safety of lighting equipment. An ordinary incandescent lamp often overheats, which can lead to deformation of a sconce or chandelier;
- Such lamps last 3-5 times longer, so buying them is more economical. But here a lot depends on the manufacturer and compliance with production technology;
- The power consumption is lower than that of a conventional lamp by about 5 times. This option can serve for years, subject to intermittent use of electricity.
Depending on the requirements, you can choose an energy-saving lamp of any power. Also depends on the power, what kind of light will be in the end (warm daylight, daylight or cold). In shape, energy-saving lamps are spiral or U-shaped. The first ones are a little more expensive, since they are more difficult to manufacture, but in terms of basic characteristics, the difference between the two types is not noticeable.
The only negative of such lighting is the high cost of the lamp, which is ten times higher than the price of an ordinary one.
