As everyone knows, incandescent lamps have a subtle flicker that negatively affects their vision if a person stays in the room for a long time. This flicker may be completely invisible to the accustomed, but it can lead to discomfort and irritability in people with sensitive nerve endings in the eyeball. 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 operating principle. Because of this type of radiation, the eyes feel strained, which can cause a person to lose sight over time. Among other things, energy saving 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 foot and analyze the question:Do LED lamps 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 living. In addition, the design of these lights is very elegant, which gives a room or a room a certain charm and attractiveness. Incandescent lamps are no longer used in European countries. In addition, there are even special legislative programs to end the production of such lamps and their use in everyday life.
It is worth noting that ordinary lamps "burn" very often. The poor quality of the filament hair leads to the failure of the light bulb itself and can only be replaced. LED lamps, or as they are popularly called energy-saving lamps, rarely become unusable and their life expectancy is 1 to 5 years, 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 shapes. In the market you can find them for every taste and color and choose the light bulb that suits your interior, since there are lamps for general (main) lighting and decoration. Don't forget about a factor like very high light output. For example, a 15 W lamp provides light for all 120 while the power consumption is minimal.
The disadvantage of these lamps is their cost, as well as the fact that lamps cannot be changed frequently from one place to another, otherwise their service life will be significantly reduced.
How to choose
When deciding on a luminaire, we recommend that you pay attention to two factors: manufacturer and properties. The number of manufacturers is huge, so you can choose exactly the lamp that suits you best. Production takes place in every country in the world, but China is still the main supplier.
However, the aspect to focus on is the product features. Namely:
- Limiting properties, i. H. Power, annealing temperature, angle, brightness, etc. The properties are directly proportional to the manufacturer. That is, housekeeping malfunctions can often be associated with incorrectly provided information about the properties of the device;
- The device of the lighting device itself, its appearance. You should pay attention to this, because only you know how this or that lamp fits into your interior. The lamp can become unusable because it does not meet its purpose;
- Check the characteristics of the power supply and microcircuits. It is important to take into account that not every housekeeper works in low temperatures, for example outside in winter. Voltage drops in the power grid are also taken into account, as this affects the overall service life of the luminaire. Therefore, read the safety information and instructions for use before use;
- Expensive LED lamps usually have diodes that can be replaced in the event of a fault. This should also be borne in mind, since the lifespan of these lamps is usually long, but due to the possibility of repair it is significantly increased, since it is cheaper to buy replaceable diodes than the lamp itself;
- In addition to an indicator of the quality of the luminaire, the box should contain a detailed file with all information on the properties and instructions for use. This is what every manufacturer does with self-respect.
Don't forget about counterfeits because they have their place in the market. This cannot be checked with the eyes, but there are dedicated laboratories that can check your equipment for counterfeiting. However, it is worth noting that fakes are sometimes no less than the original.
Calculation of energy savings
As mentioned above, the main advantage of LED lamps is energy saving. This saving is due to the fact that a large amount of light radiation is generated per unit with low power consumption.
Below we give you a comparison table of some lamps as opposed to LED. Perhaps the most important 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), 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 |
| 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 remembering that all "housekeepers" emit tightly focused light energy. On the boxes, manufacturers often indicate this parameter, so you should carefully weigh the choice of lighting device so that it does not cause discomfort. There is also a parameter such as the color heat transfer 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 to conveniently illuminate the premises depending on the needs of the buyer.
Conclusion
So, from all of this, we can conclude that, among all the lighting devices on the market, the most profitable is to take an LED lamp, in order to save electricity and, accordingly, money.
We hope that this article has given you an answer to the question of whether LED bulbs save energy and whether it is true.
