As everyone knows, incandescent lamps have a subtle flicker, which when a person is in the room for a long time, negatively affects their vision. For those who are used to it, this flickering may be completely invisible, but for people with sensitive nerve endings in the eyeball, it can cause inconvenience and also lead to irritability. Therefore, LED lamps have been invented which 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 overworked, which can lead to loss of sight after a while. Among other things, saving energy is an important factor. An LED lamp is much more economical 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 stand 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 lights is very elegant, which gives any room or room a certain charm and appeal. In European countries, incandescent lamps are no longer used. In addition, there are even special legislative programs to eradicate the production of such lamps and their use in everyday life.
It should be noted that ordinary lamps "burn" very often. The poor quality of the filament bristles causes the bulb itself to fail, and it can only be replaced. LED lamps, or as they are commonly called energy saving lamps, seldom become unusable and their lifespan is 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 kinds of shape. In the market, you can find them for every taste and color, as well as choose the right bulb for your interior, because there are lamps for general (main) lighting and for decoration. Do not forget about a factor such as very high light output. For example, a 15W lamp provides light for all 120, while the voltage consumption is minimal.
The downside of such lamps is their cost, as well as the fact that the lamps cannot be frequently changed from one place to another, otherwise its service life will be significantly reduced.
How to choose
When choosing which luminaire to buy, we recommend that you pay attention to two factors: the manufacturer and the features. The number of manufacturers is huge, so you can choose exactly the lamp that is best for you. Production takes place in all countries of the world, but China remains the main supplier.
However, the aspect to focus on is that of the product characteristics. To know:
- Limiting characteristics, i. e. power, incandescent temperature, angles, brightness, etc. The characteristics are directly proportional to the manufacturer. In other words, the malfunctions of housekeepers can often be associated with incorrectly provided information on the characteristics of the device;
- The apparatus of the lighting device itself, its appearance. It is worth paying attention to it, because only you know how this or that lamp will adapt to your interior. The lamp may become unusable because it does not match its purpose;
- Check the properties of the power supply and microcircuits. It is important to take into account that not all cleaning ladies will work at 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 operating instructions;
- Expensive LED lamps most often have diodes which can be replaced in the event of a failure. It is also worth considering, since the service life of such lamps is usually high, but due to the possibility of repair, it increases significantly, since it is cheaper to buy replaceable diodes than thelamp itself;
- In addition to an indicator of the quality of the luminaire, the box should contain a detailed file with all information on the characteristics and instructions for use. That's what any self-respecting manufacturer does.
Do not forget about counterfeits, because they have their place in the market. It is impossible to verify this with the naked eye, but there are special labs where you can check if your equipment is counterfeit. Although it is interesting that the 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 power consumption a large amount of light radiation is generated per unit.
Below we give you a comparison 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).
So:
| Incandescent lamp power (W) | Fluorescent lamp, power (W) | LED lamp power (W) | Luminous 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's worth considering the fact that all "housekeepers" emit tightly focused light energy. On the boxes, manufacturers often indicate this parameter, so you need to think carefully about the choice of the 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 only have one shade, yellow, one 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 the most profitable to take a LED lamp, in order to save electricity and, as a result, your money. .
We hope this article has given you an answer to the question of whether LED lamps save energy and is it true.
