As everyone knows, incandescent lamps have subtle flickering, which, when a person is in the room for a long time, negatively affects his vision. For those who are used to it, this flickering may be completely invisible, but for people with sensitive nerve endings in the eyeball, this can cause discomfort and also lead to irritability. Therefore, LED lamps have been invented that do not have such a defect. They also do not have harmful radiation such as ultraviolet and infrared light. In fact, this is its main working principle. Due to this type of radiation, the eyes feel overwhelmed, as a result of which, a person may lose their sight after a while. Among other things, energy saving is an important factor. An LED lamp is much cheaper 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
As mentioned above, the main advantage of LED lamps is energy saving, and in our country, saving electricity is the key to comfortable life. In addition, the design of these luminaires is very elegant, which gives a room a certain charm and appeal. In European countries, incandescent lamps are no longer used. In addition, there are even special legislation programs to eradicate the production of this type of lamp and its use in everyday life.
It is worth noting that ordinary lamps "burn out" very often. 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 1 to 5 years, and sometimes even longer. Such a long service life lies in its structure.
LED lighting fixtures are made from a variety of materials and they also give them different types of shape. In the market you can find them for all tastes and colors, as well as choose the bulb that suits your interior, since there are lamps for general (main) lighting and for decoration. Don't forget about a factor like very high light output. For example, a 15 W lamp provides light for 120, while the voltage consumption is minimal.
The disadvantage of these lamps is their cost, as well as the fact that the lamps cannot be frequently changed from one place to another, otherwise their service life will be significantly reduced.
How to choose
When choosing which lighting device to buy, we recommend that you pay attention to two factors: the manufacturer and the characteristics. The number of manufacturers is huge, allowing you to choose exactly the lamp that suits you best. Production takes place in every country in the world, but China is still the main supplier.
However, the aspect to focus on is the characteristics of the product. Namely:
- Limiting characteristics, i. e. wattage, incandescent temperature, angles, brightness, etc. The characteristics are directly proportional to the manufacturer. That is, often the malfunction of housekeepers can be associated with incorrectly provided information about the characteristics of the device;
- The device of the lighting device itself, its appearance. It is worth paying attention to this, because only you know how this or that lamp will fit into your interior. The lamp may become unusable because it does not serve its purpose;
- See the properties of the power supply and microcircuits. It is important to note that not all domestic workers will work in low temperatures, for example outdoors in winter. In addition, voltage drops in the electrical network 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 often have diodes that can be replaced in the event of a failure. It is also worth paying attention to this, since generally 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;
- In addition to an indicator of the quality of the luminaire, the box must contain a detailed file with all the information on the characteristics and instructions for use. This is what every self-respecting manufacturer does.
Don't forget about fakes as they have a place to be in the market. It is impossible to verify this with the naked eye, but there are special labs where you can verify that your equipment is not fake. Although it is worth noting that counterfeits are sometimes not inferior in quality to the original.
Calculation of energy savings
As mentioned above, the main advantage of LED bulbs is energy saving. This saving lies in the fact that with low energy consumption, a large amount of light radiation is generated per unit.
Below we give you a comparative table of some lamps as opposed to LEDs. Perhaps the main characteristic of a lamp is its light emission, which is measured in lumens (Lm).
Then:
| Incandescent Lamp Power (W) | Fluorescent lamp, wattage (W) | LED Lamp Power (W) | Luminous flux (lm), average |
| twenty | 5-7 | 23 | 250 |
| 40 | 10-13 | 4-5 | 400 |
| 60 | 15-16 | 8-10 | 700 |
| 75 | 18-20 | 10-12 | 900 |
| hundred | 25-30 | 12-15 | 1200 |
| 150 | 40-50 | 18-20 | 1800 |
| 200 | 60-80 | 25-30 | 2500 |
The choice is obvious, but the fact that all "housekeepers" emit narrow-focus light energy is worth considering. On the boxes, manufacturers often indicate this parameter, so you need to carefully consider the choice of lighting device so that it does not cause discomfort. There is also a parameter such as the heat transfer of color or, more simply, the color of the light emission. Incandescent lamps have only one shade, yellow, an LED lamp has various colors and shades. This is also done for the convenience of lighting the premises, depending on the needs of the buyer.
conclusion
So from all of the above, we can conclude that among all the lighting devices on the market, it is more profitable to carry an LED lamp to save electricity and consequently your money.
We hope this article has given you an answer to the question whether LED lamps save energy and it is true.
