As everyone knows, incandescent lamps have a subtle flicker, which, when a person is in a room for a long time, negatively affects his vision. For those who are accustomed, these flickers may not be fully visible, but for people who have sensitive nerve endings on the eyeballs, this can cause discomfort and even irritation. Therefore, LED lights have been created that do not have such defects. They also do not have harmful radiation such as ultraviolet and infrared light. In fact, this is their main operating principle. Due to this type of radiation, the eyes feel too much work, as a result, a person may lose vision after a while. Among other things, energy saving is an important factor. LED lights are much more economical than incandescent lamps, but the price of diode lights is much higher. So, in this article we will tell you how to choose an LED leg and analyze the question:Do LED bulbs save energy?. . .
Advantages and disadvantages
As mentioned above, the main advantage of LED lighting is energy saving, and in our country, electricity saving is the key to a comfortable life. In addition, the design of these lighting fixtures is very elegant, which gives the room or rooms a certain charm and charm. In European countries, incandescent lamps are no longer used. In addition, there is also a special legal program to eradicate the production of such lamps and their use in everyday life.
Keep in mind that ordinary lights "burn out" very often. Poor filament hair quality leads to the failure of the bulb itself, and it can only be replaced. LED lights, or as they are known as energy -saving lights, rarely become unusable and their lifespan is from 1 to 5 years, and sometimes longer. Such a long lifespan lies in its structure.
LED lighting devices are made of a variety of materials, and also give them a wide variety of shapes. In the market you can find them for every taste and color, as well as choose a light bulb that suits your interior, as there are lamps for general (main) lighting and for decoration. Don't forget about factors such as very high light output. For example, a 15 W lamp provides light for all 120, while voltage consumption is minimal.
The disadvantage of this lamp is its cost, as well as the fact that the lamp can not be often changed from one place to another, otherwise its service life will be significantly reduced.
How to choose
When you choose a lighting fixture to buy, we advise you to pay attention to two factors: manufacturer and features. The number of manufacturers is huge, which allows you to choose the most suitable lamp for you. Production takes place in all countries of the world, but China is still a major supplier.
However, the aspect that needs to be focused on is the product features. Namely:
- Limiting features, i. e. power, incandescent temperature, angle, brightness, etc. Its features are directly proportional to the manufacturer. That is, often the malfunction of the maid can be attributed to incorrectly given information about the features of the device;
- The lighting device itself, apparently. This is worth noting, because only you know how this or that lamp fits into your interior. The lamp may become unusable due to the fact that it does not suit its purpose;
- Check the nature of the power supply and microcircuits. It is important to take into account that not every maid will work at low temperatures, for example, outside in the winter. Also, the voltage drop in the power grid is 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 lights often have diodes that can be replaced in the event of a failure. This is also worth noting, because 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 a replaceable diode than the lamp itself;
- In addition to the luminaire quality indicator, the box should contain a detailed file with all information about the features and instructions for use. This is what every self -respecting producer does.
Do not forget about fakes, because it has a place to be on the market. It is impossible to check this with the naked eye, but there are special labs where you can check your equipment for fakes. Although it should be noted that fakes are sometimes not inferior in quality to the originals.
Energy saving calculations
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 produced per unit.
Below we give you a comparison table of some lights versus LEDs. Perhaps the main feature of a lamp is its light emission, which is measured in Lumens (Lm).
So:
| Incandescent lamp power (W) | Fluorescent lamps, power (W) | LED light power (W) | Luminous flux (lm), average |
| twenty | 5-7 | 2-3 | 250 |
| 40 | 10-13 | 4-5 | 400 |
| 60 | 15-16 | 8-10 | 700 |
| 75 | 18-20 | 10-12 | 900 |
| a 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 "housekeepers" emit narrowly concentrated light energy. On the box, the manufacturer often indicates this parameter, so you should carefully consider the choice of lighting device so that it does not cause discomfort. There are also parameters such as color heat transfer, or, more simply, light emission color. Incandescent lights have only one color, yellow, LED lights have several colors and shades. This is also done for the convenience of lighting the premises, depending on the needs of the buyer.
Conclusion
Therefore, from all the above, we can conclude that among all the lighting devices on the market, it is most profitable to take LED lighting, to save electricity, and, consequently, your money.
We hope this article has given you an answer to the question of whether LED lighting saves energy and whether it is true.
