Do LED bulbs save energy?

As everyone knows, incandescent lamps have a subtle flicker, which, when a person is in the room for a long time, negatively affects his vision. Accustomed to, this flicker may be completely invisible, however, for people with sensitive nerve endings in the eyeball, this can cause inconvenience, as well as lead to irritability. Therefore, LED lamps have been invented that do not have this defect. They also do not have harmful radiation such as ultraviolet and infrared light. In fact, this is their main principle of operation. Due to this kind of radiation, the eyes feel overwork, as a result of which a person may lose sight after a while. Among other things, energy saving is an important factor. An LED lamp is much more economical than incandescent lamps, but the price of a diode lamp is much higher. Therefore, in this article we will tell you how to choose an LED foot and analyze the question: Do LED bulbs save energy?.

Advantages and disadvantages

Advantages and disadvantages of LED lamps

As mentioned above, the main advantage of LED lamps is energy saving, and in our country, electricity saving is a guarantee of a comfortable life. Moreover, the design of these lighting devices is very elegant, which gives a room or room a certain charm and attractiveness. In European countries, incandescent lamps are no longer used. Moreover, there are even special programs of legislation to eradicate the production of such lamps and their use in everyday life.

It is worth noting that ordinary lamps very often "burn". The poor quality of the filament hair leads to the failure of the bulb itself, and it can only be replaced. LED lamps, or as they are popularly called energy-saving lamps, rarely become unusable and their life expectancy is from 1 to 5 years, and sometimes longer. Such a long lifespan lies in their structure.

LED lighting devices are made from a variety of materials, and also give them different types of shape. On the market you can find them for every taste and color, as well as choose the light bulb that suits your interior, since there are lamps for general (main) lighting, and for decoration. Do not forget about such a factor as a very high light output. For example, a 15 W lamp provides light for all 120, while the voltage consumption is minimal.

The disadvantage of these lamps is their cost, as well as the fact that lamps cannot be frequently changed from one place to another, otherwise its service life will be significantly reduced.

How to choose

How to choose an LED bulb

When you choose which lighting fixture to buy, we advise you to pay attention to two factors: manufacturer and characteristics. The number of manufacturers is huge, which allows you to choose exactly the lamp that suits you best. Production takes place in all countries of the world, but China is still the main supplier.

However, the aspect that needs to be focused on is product characteristics.Namely:

  • Limiting characteristics, that is, power, incandescent temperature, angles, brightness, etc. The characteristics are directly proportional to the manufacturer. That is, often malfunctions of housekeepers can be associated with incorrectly provided information about the characteristics of the device;
  • The device of the lighting device itself, its appearance. This is worth paying attention to, because only you know how this or that lamp will fit into your interior. The lamp may become unusable due to the fact that it does not correspond to its purpose;
  • Check out the properties of the power supply and microcircuits It is important to take into account that not every housekeeper will work at low temperatures, for example, outside in winter. Also, voltage drops in the power grid are taken into account, as this affects the durability of the luminaire as a whole. Therefore, before use, read the safety precautions and instructions for use;
  • Expensive LED lamps most often have diodes that can be replaced in case of failure. This is also worth paying attention to, since usually the service life of these lamps is high, but due to the possibility of repair, it increases significantly, because it is cheaper to buy replaceable diodes than the lamp itself;
  • As well as an indicator of the quality of the luminaire, the box should contain a detailed file with all information about the characteristics and instructions for use. This is what every self-respecting manufacturer does.

Do not forget about fakes, as they have a place to be on the market. It is impossible to check this by eye, but there are special laboratories in which you can check your equipment for fake. Although it is worth noting that fakes are sometimes not inferior in quality to the original.

Energy savings calculation

Energy savings calculation

As mentioned above, the main advantage of LED bulbs is energy saving. This saving lies in the fact that with low power consumption, a large amount of light radiation is generated per unit.

Below we give you a table comparing some lamps as opposed to LED. Perhaps the main characteristic of a lamp is its light emission, which is measured in Lumens (Lm).

So:

Incandescent lamp power (W) Fluorescent lamp, power (W) LED lamp, power (W) Luminous flux (lm), average
20 5-7 2-3 250
40 10-13 4-5 400
60 15-16 8-10 700
75 18-20 10-12 900
100 25-30 12-15 1200
150 40-50 18-20 1800
200 60-80 25-30 2500

The choice is obvious, but it is worth considering the fact that all "housekeepers" emit narrowly focused light energy. On boxes, manufacturers often indicate this parameter, so you should carefully consider the choice of a lighting device so that it does not lead to discomfort. There is also such a parameter as color heat transfer, or, more simply, the color of light emission. Incandescent lamps have only one shade, yellow, LED lamp has several colors and shades. This is also done for the convenience of lighting the premises, depending on the needs of the buyer.

Output

So, from all of the above, we can conclude that among all the lighting fixtures on the market, it is most profitable to take an LED lamp, in order to save electricity, and therefore your money.

We hope this article has given you an answer to the question of whether LED lamps save energy and is it true.
