As everyone knows, incandescent lamps have a subtle flicker that negatively affects the ability to see when a person is in the room for a long time. For those who are accustomed to it, this tremor may be completely invisible, but for people with sensitive nerve endings in the eyeball, it can be annoying and can also cause irritability. Therefore, LED lamps were invented without such a defect. They also do not contain 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 overworked, as a result of which a person may lose his sight after a while. Among other things, energy saving is an important factor. LED bulbs are more economical than incandescent bulbs, but LED bulbs cost more. Therefore, in this article we will tell you how to choose an LED leg and analyze the question:Do LED lamps save energy?. . .
Pros and cons
As mentioned above, the main advantage of LED lamps is energy saving, and saving electricity in our country is the key to a comfortable life. In addition, the design of these lighting fixtures is very elegant, which gives the room or room a certain charm and attractiveness. Incandescent lamps are no longer used in European countries. In addition, there are even special legislative programs to eliminate the production and use of such lamps in everyday life.
It should be noted that ordinary lamps very often "light up". The poor quality of the filament hair leads to the failure of the bulb itself and can only be replaced. LED lamps, or energy-saving lamps as they are popularly called, rarely become unusable and last from 1 to 5 years, and sometimes longer. Such a long life is in their structure.
LED lighting devices are made of different materials and give them different shapes. You can find them on the market for every taste and color, as well as lamps for interior (basic) lighting and decoration, so you can choose a lamp that suits your interior. Don't forget a factor like very high light output. For example, a 15 W lamp illuminates all 120, and voltage consumption is minimal.
The disadvantage of these lamps is their price, as well as the fact that the lamps can not be changed from one place to another often, 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: the manufacturer and the features. There are a large number of manufacturers, which allows you to choose the most suitable lamp. Production is carried out in all countries of the world, but China is still the main supplier.
However, the aspect to consider is the characteristics of the product. Namely:
- Limiting properties, ie power, incandescent temperature, angles, brightness, etc. Features are directly proportional to the manufacturer. That is, often domestic workers' malfunctions can be attributed to incorrect information about the device's features;
- Lighting device itself, appearance. It is worth noting, because only you know how this or that lamp will fit into your interior. The lamp may become unusable because it does not meet its intended purpose;
- Check the characteristics of the power supply and chips. It should be borne in mind that not every domestic worker will work outside at low temperatures, for example in winter. Also, voltage drops in the mains are taken into account, as this affects the durability of the lamp as a whole. Therefore, read safety precautions and instructions for use before use;
- Expensive LED lamps have diodes that can be replaced in case of most failures. It is also worth noting that these lamps usually have a long service life, but increase significantly due to the possibility of repair, because it is cheaper to buy replaceable diodes than the lamp itself;
- As an indicator of the quality of the fixture, the box should contain a detailed file that contains all the information about the features and rules of use. Every self-respecting manufacturer does it.
Don't forget the fakes, because they have a place in the market. It is impossible to check it with the naked eye, but there are special laboratories where you can check whether the equipment is counterfeit. It should be noted that the quality of fakes is sometimes not inferior to the original.
Calculation of energy savings
As mentioned above, the main advantage of LED lamps is energy saving. This conclusion is 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, unlike LEDs. Perhaps the main feature of the lamp is the light emission measured in Lumens (Lm).
So that:
| Incandescent lamp power (W) | Fluorescent lamp, power (W) | LED lamp power (W) | Light flux (lm), medium |
| twenty | 5-7 | 2-3 | 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 it is worth noting that all "domestic workers" emit light energy in the narrow focus. Manufacturers often indicate this parameter on the boxes, so you should carefully consider the choice of lighting fixture so as not to cause inconvenience. There is also a parameter such as color heat transfer or, more simply, the color of light emission. Incandescent lamps have only one shade, yellow, LED lamps have several colors and shades. This is also done for the convenience of lighting the buildings, depending on the needs of the buyer.
The result
So, from all of the above, we can conclude that among all the lighting devices on the market, it is most profitable to buy an LED lamp to save electricity and, accordingly, your money.
We hope this article has answered the question of whether LED lamps save energy and whether this is true.
