As everyone knows, incandescent bulbs have a subtle flicker, which, when a person is in the room for a long time, negatively affects his vision. For those accustomed, this flicker may be completely invisible, but for people with sensitive nerve endings in the eyeball, it can cause discomfort and lead to irritability. Therefore, LED lamps have been invented that do not have such a disadvantage. They also do not have harmful radiation such as ultraviolet and infrared radiation. In fact, this is their main working principle. Due to this radiation, the eyes feel overloaded, which can cause a person to lose their sight after a while. Among other things, energy savings are an important factor. An LED lamp is much more economical than an incandescent lamp, 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 already mentioned, the main advantage of LED lamps is energy savings, and in our country saving electricity is the key to a comfortable life. Moreover, the design of these lighting fixtures is very elegant, which gives the room or rooms a certain charm and attractiveness. Incandescent bulbs are no longer used in European countries. Moreover, there are even special legislative programs to eradicate the production of such lamps and their use in everyday life.
It is worth noting that ordinary lamps "up" very often. Poor thread quality leads to damage to 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 lifespan is from 1 to 5 years, and sometimes longer. Such a long lifespan lies in their structure.
LED lighting devices are made of various materials, and give them different types of shapes. You can find them on the market for everyone's taste and color, as well as choose a light bulb that suits your interior, because there are lamps for general (main) lighting and decoration. Don’t forget a factor like very high light output. For example, a 15 W lamp provides light for all 120, while power consumption is minimal.
The disadvantage of these lamps is their price, as well as the fact that the lamps can not be changed often from one place to another, because otherwise their lifespan will be significantly reduced.
How to choose
When choosing a lighting fixture to buy, we advise you to pay attention to two factors: the manufacturer and the 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 to focus on is the characteristics of the product. namely:
- Limit characteristics, ie power, bulb temperature, angles, brightness, etc. The characteristics are directly proportional to the manufacturer. That is, often housewife failures can be related to inaccurate information about the characteristics of the device;
- 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 due to the fact that it does not fit its purpose;
- Check the properties of the power supply and microcircuits. It is important to take into account that not every housewife will work at low temperatures, for example, outside in winter. Voltage drops in the electrical network are also taken into account, as this affects the durability of the lamp as a whole. Therefore, read the safety precautions and instructions for use before use;
- Expensive LED lamps usually have diodes that can be replaced in case of failure. It is also worth paying attention to this, because usually the lifespan 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 the lamp quality indicator, the box should contain a detailed file with all the information about the characteristics and instructions for use. This is done by every manufacturer who respects himself.
Don’t forget about counterfeits, because they have a place in the market. It is impossible to check this with the naked eye, but there are special laboratories where you can check for fake equipment. Although it is worth noting that counterfeits are sometimes not inferior in quality to the original.
Energy saving budget
As already mentioned, the main advantage of LED bulbs is energy savings. 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 the 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 |
| 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 taking into account the fact that all "housewives" emit narrowly focused light energy. Manufacturers often state this parameter on the boxes, so the choice of lighting device should be carefully considered so as not to cause discomfort. There is also such a parameter as the heat transfer color or, more simply, the color of the light emission. Incandescent bulbs have only one shade, yellow, LED lamp has several colors and shades. This is also done for easier lighting of the room, depending on the needs of the customer.
Conclusion
So, from all the above, we can conclude that among all the lighting devices on the market, it is most cost-effective to take an LED lamp, in order to save electricity and, consequently, your money.
We hope that this article has given you the answer to the question of whether LED lamps save energy and whether this is true.
