As everyone knows, incandescent bulbs have a subtle blink that, if a person stays in the room for a long time, negatively affects their vision. For those who are used to it, this flicker can be completely invisible, but for those with sensitive nerve endings in the eyeball, it can also cause discomfort and irritability. Therefore, LED lamps without such a defect have been invented. They do not have harmful radiation such as ultraviolet and infrared light. In fact, this is their main principle of operation. Because of such radiation, the eye feels overwhelmed, which can cause a person to lose their vision after a while. 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 pin 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 Hungary, energy saving is the key to a comfortable life. In addition, the design of these luminaires is very elegant, which lends a certain charm and appeal to a room or room. Incandescent lamps are no longer used in European countries. Moreover, there are even special legislative programs to phase out the manufacture of such lamps and their use in everyday life.
It is worth noting that ordinary lamps very often "light up". Poor filament quality leads to failure of the bulb itself and is only replaceable. LED lamps, or as they are popularly called energy-saving lamps, rarely become unusable, have a lifespan of 1 to 5 years, and sometimes even longer. Such a long service life lies in their structure.
LED lighting fixtures are made of a wide variety of materials and give them different shapes. On the market, you can find all the tastes and colors, as well as choose the bulb to suit your interior, as there are general (main) lighting and decorative lamps. Let’s not forget about a factor like very high light output. For example, a 15 W lamp illuminates all 120 while the voltage consumption is minimal.
The disadvantages of these lamps are their cost and the fact that the lamps cannot be replaced often from one place to another, otherwise their lifespan is significantly reduced.
How to choose
When choosing which luminaire to buy, we advise you to consider two factors: the manufacturer and the characteristics. The number of manufacturers is huge, so you can choose the right lamp for you. Production takes place in all countries of the world, but China remains the main supplier.
However, the aspect to focus on is the characteristics of the product. Namely:
- Boundary characteristics, ie wattage, incandescent lamp temperature, angles, brightness, etc. The characteristics are directly proportional to the manufacturer. That is, the failure of housekeepers can often be associated with incorrectly provided information about the characteristics of the device;
- The device of the lighting device itself, its appearance. This is worth paying attention to, because only you know how this or that lamp will fit into your interior. The lamp may become unusable because it does not fit its purpose;
- Check the power supply and microcircuit properties. It is important to note that not all housekeepers work in low temperatures, such as outdoors in winter. The voltage drop in the mains is also taken into account, as this affects the durability of the luminaire as a whole. Therefore, read the safety precautions and instructions for use before use;
- Expensive LEDs most often have diodes that can be replaced in the event of a failure. This is also worth paying attention to, as these lamps usually have a long lifespan, but due to the possibility of repair, this increases significantly because it is cheaper to buy replaceable diodes than the lamp itself;
- In addition to the luminaire quality indicator, the box must also contain a detailed file containing all information about the features and instructions for use. This is what every self-respecting manufacturer does.
Let’s not forget about fakes either, because they have a place in the market. This cannot be checked visually, but there are special laboratories where you can check your equipment for fakes. Although it is worth noting that the quality of counterfeits is sometimes no worse than the original.
Energy saving calculation
As mentioned above, the main advantage of LED bulbs is energy saving. This saving is due to the large amount of light emitted per unit at low consumption.
Below is a comparative table of some of the lights versus LEDs. Perhaps the main feature of a lamp is its light output, which is measured in Lumens (Lm).
Thus:
| 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 |
| 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 every "housekeeper" emits a narrow-focus light energy. 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 the light output. Incandescent bulbs have only one shade, yellow, LED bulbs have several colors and shades. This is also done for the convenience of lighting the room, depending on the needs of the buyer.
Conclusion
So from the above, it can be concluded that the most profitable of all the lighting devices on the market is to buy an LED lamp to save energy and accordingly money.
We hope this article provides an answer to the question of whether LED lights save energy, and that this is true.
