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. For those used to it, this flicker can be completely invisible, but for people with sensitive nerve endings in the eyeball, this can cause inconvenience and even 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 their main principle of operation. Due to this type of radiation, the eyes feel overstrained, 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 a comfortable life. In addition, the design of these luminaires is very elegant, which gives a room or room a certain charm and attractiveness. In European countries, incandescent lamps are no longer used. In addition, there are also special legislative programs to eradicate the production of such lamps and their use in daily life.
It is worth noting that ordinary lamps "burn" very often. Poor hair quality of the filament leads to the failure of the bulb itself, which can only be replaced. LED lamps, or as they are commonly called energy saving lamps, rarely become unusable and their life expectancy ranges from 1 to 5 years, and sometimes even 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 bulb that fits your interior, as there are lamps for general (main) lighting and for decoration. Don't forget a factor like 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 the lamps cannot be changed frequently from one place to another, otherwise its service life will be significantly reduced.
How to choose
When choosing which lighting fixture to buy, we recommend that you 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 remains the main supplier.
However, the one thing to focus on is the product features. That means:
- Limiting characteristics, i. e. power, incandescent temperature, angles, brightness, etc. The characteristics are directly proportional to the manufacturer. That is, often the malfunctions of the rulers 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, because only you know how this or that lamp will fit into your interior. The lamp can become unusable due to the fact that it does not correspond to its purpose;
- Check the properties of the power supply and microcircuits. It is important to take into account that not all housekeepers 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 service life of the appliance 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 breakdown. It is also worth paying attention, 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;
- In addition to an indicator of the quality of the appliance, the box should contain a detailed file with all information on the characteristics and instructions for use. This is what every self-respecting manufacturer does.
Don't forget the fakes, as they have a place to be in the market. It is impossible to check it by eye, but there are special workshops where you can check your equipment for fakes. Although it is worth noting that fakes 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 comparison table of some lamps compared to LEDs. Perhaps the main feature of a lamp is its light output, which is measured in Lumen (Lm).
Like this:
| Incandescent lamp power (W) | Fluorescent lamp, power (W) | LED lamp power (W) | Luminous flux (lm), average |
| winds | 5-7 | 2-3 | 250 |
| 40 | 10-13 | 4-5 | 400 |
| 60 | 15-16 | 8-10 | 700 |
| 75 | 18-20 | 10-12 | 900 |
| one hundred | 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 "maids" emit tightly focused light energy. On the boxes, manufacturers often indicate this parameter, so you should carefully consider the choice of the lighting device so that it does not cause discomfort. There is also a parameter such as the heat transfer of the color or, more simply, the color of the light emission. Incandescent lamps have only one shade, yellow, an 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.
Conclusion
So, from all of the above, we can conclude that among all the lighting devices on the market, it is more profitable to take an LED lamp, to save electricity and, consequently, your money.
We hope this article has given you an answer to the question of whether LED lamps save energy and it is true.
