Currently, more lighting sources have appeared, and each type positions itself as the brightest, most economical and most comfortable for the eyes. Let’s try to understand this diversity and look at how LED lamps differ from energy-saving lamps.
LED lamps and their features
First of all, let's give a definition - this is a solid-state lighting source, the operating principle of which is based on receiving light radiation when electricity passes through a certain zone of semiconductors. Thus, LEDs can be defined as semiconductors,
intended for radiation luminous flux. Their operating principle differs significantly from all other types of lamps.
Features of compact energy-saving lamps
Certain similarities between energy-saving and LED light bulbs
Concerning energy saving lamps, then they also use in great demand, because they provide a high-quality color flow, very comfortable for the eyes, and at the same time also retain the energy-saving function. In principle, LED and energy-saving lamps are similar in this regard, and their costs are not too different. The main thing is that these lamps are interchangeable, because the manufacturers took care to match the base of any lamp and the lamp sockets for them.
Interchangeability of LED and energy-saving lamps
Currently, the interchangeability of lighting sources is fundamental for manufacturers, and therefore almost all lamps are produced with different sizes plinth, including two standard solutions. In this case, an energy-saving lamp may look like an incandescent lamp with a frosted bulb.
The fact is that modern fluorescent lamps, which are energy-saving by their operating principle, are manufactured in a special way: a thin luminescent tube is enclosed in a quartz flask, which in shape and size is absolutely identical to a conventional incandescent lamp and is screwed into a standard electric one.
Gradual complete replacement of energy-saving lamps with LEDs
LED bulbs may also have a similar shape, and therefore it is impossible to be sure of the type of lamp by simple inspection, but you should check the information on the packaging, which indicates the rated voltage of the lamp, its type, etc. helpful information, including the life of the lamp. It should also be taken into account that the non-standard original shape of the lamp increases its cost not because it has any improvements, but precisely because of the shape, the production of which is expensive. But the faster and more manufacturers improve the LED light bulb, the more attractive its price becomes. So very soon we will witness complete replacement all types of lamps to LED.
Often when choosing lighting lamps a question arises. Which lamp to choose for your home?
Lighting lamps are:
Incandescent lamps.
Fluorescent lamps.
LED bulbs
First, let's look at the main characteristics of incandescent lamps. Incandescent lamps come in both vacuum and gas-filled types. The filament is made from tungsten. This is the most refractory metal. IN periodic table located at number 74. The name of this metal comes from the surname famous physicist Stephen Wolfram.
Incandescent lamp device. The flask contains a tungsten filament. To prevent the thread from oxidizing, there may be a vacuum or inert gas. (Argon, krypton or xenon.) The light output and brightness of the lamps are different and depend on the gas filling the flask. U halogen lamps the light output is approximately 3 times greater, but there should be no dust or dirt on it. Otherwise they will quickly fail.
The main advantages of incandescent lamps are: simplicity, low cost, no control circuits are needed, wide range power, small dimensions.
Main disadvantages: low efficiency (90% of power consumption goes into heat), fragility (Approximately 1000 hours) Types of incandescent lamps Marking of incandescent lamps:
B - there is a vacuum in the lamp bulb;
B - bispiral lamp filled with argon;
G - gas-filled lamp filled with argon.

Now let’s look at the main types and characteristics of energy-saving lamps.
Energy saving lamps are a variant of fluorescent lamps. Typically, these devices (energy-saving lamps) are produced with the same base as incandescent lamps. This allows them to be used instead of incandescent lamps without modification.
The operating principle of these devices is as follows. In a tube filled with mercury vapor there are 2 spirals heated to 900-1000 degrees. The base contains a starting circuit and a converter that converts current from a fifty-hertz network to more high frequency. The tube containing mercury vapor is coated with a phosphor that converts the radiation of low-temperature mercury plasma into the visible spectrum.
Energy saving lamps last longer than incandescent lamps. For comparison, an incandescent lamp lasts 1000 hours, and an energy-saving lamp lasts 10,000 hours. This is an approximate service life, which usually depends on the manufacturer. His qualities. ESL is approximately five times more economical than an incandescent lamp at the same lighting intensity. For home use energy-saving ones are available with power from 7 to 250 W.
Labeling of energy-saving lamps in Russia:
L - fluorescent lamp;
B - white lamp;
TB - a lamp that produces a warm white color;
D - fluorescent lamp;
C - a lamp with better light output;
E - a lamp that has better environmental friendliness;

Brief overview of LED lamps.
These are the most modern lighting. They are pushing energy-saving lamps out of the market. An LED lamp consists of a rectifier, usually assembled in a base, and LEDs. For domestic needs, three types of bases are used:
E 14 - base diameter 14 mm.
E 27 - base diameter 27 mm.
E 40 base diameter 40 mm.
The most common base with a diameter of 27 mm. LED lamps are more energy efficient than other lamps. Almost 90% of the energy is spent on radiation. The lamps are environmentally friendly and completely fireproof.
LED lamps are divided according to the “warmth” of radiation:
2700 K - have a “warm” tint like a regular incandescent lamp.
3000 K - The color is also “warm”, but in a whiter shade.
4500-5000 K - have “daylight” light, which is closer to energy-saving lamps.
The light of the lamp and its power are selected individually. The choice largely depends on the interior and the size of the illuminated area.

Table of differences between energy-saving LED lamps and incandescent lamps
This article provides only the basic characteristics of lighting lamps. But based on these data, you can understand the differences between energy-saving LED lamps and incandescent lamps. Prices are indicative. But we can confidently say that to illuminate places that need constant lighting, it is advisable to use LED lamps.
And, for example, you can safely install an incandescent lamp in the cellar. Since the lamp is very rarely used. Which lamp to choose needs to be decided individually for each specific case, guided by the table and characteristics of the lamps. But we can say with confidence that the future belongs to LED lamps.
IN Lately classic lamps incandescent lamps with a very limited service life (approximately 1000 hours) are being actively replaced by LED energy-saving lamps. After all, the latter will last you several times longer (up to 100,000 hours). They have the highest conversion efficiency into light energy among other artificial light sources. And to make the room look more elegant, you can...
Why is it worth replacing energy-saving lamps with LEDs?
The most important advantage is that LED energy saving lamps are more energy efficient than others. With the increase in the cost of energy, the cost factor of electricity becomes increasingly relevant. For example, in some cities, about 40% of the cost is spent on street lighting alone.
Many people are interested in the question: what is the difference between LED lamps and energy-saving lamps? The first thing that comes to mind when comparing is the brightness of the glow, which is measured in lumens. Traditional incandescent lamps with a power of 100 W have an output of 1700 lumens, energy-saving 13 W devices have an output of 800 lm, and LED lamps have an output of 1000 lm.
Heat dissipation is another way LED lamps differ from energy-saving lamps. The former heat up to only 30.5 while the latter heat up to 81.7. This means that when using diodes, the risk of fire is reduced significantly.
Which lamp is better to buy?
|
Naturally, to the question of which is better to buy LED lamps or energy-saving ones, the answer will be LED, also because according to the passport, their service life is 50,000 (in fact, much longer). It's much best indicator than energy-saving ones (total 8,000). Many large commercial companies are switching to LED solely because they spend so much money on replacing lamps.
If we compare LED lamps and energy-saving lamps, the advantages of the former include the fact that diode devices can be recycled, since they do not contain mercury, which seeps into water and soil. Energy-saving ones emit greenhouse gases during disposal and use. Another difference between energy-saving lamps and LED lamps is that the former cannot be called safe. The latter are considered completely safe for humans; many materials LED devices can be recycled.
Comparison of LED lamps and energy-saving lamps
What is the difference between an energy-saving lamp and an LED lamp? Comparison and difference of incandescent lamps.
For years, numerous LED lamp manufacturers have tried to make a light bulb that performs just like a good old incandescent lamp, while retaining all the features of LED lamps: low energy consumption, low heat generation and low environmental impact. environment, the end result was energy-saving lamps or compact fluorescent lamps.
Let's compare in more detail how an energy-saving lamp differs from an LED lamp, as well as an incandescent lamp.
Comparison of brightness and efficiency
Obviously, the first factor that comes to mind when we compare lamp performance is brightness, which is measured in lumens (lm).
A 100W traditional incandescent bulb will output 1700 lumens, a 13W energy saving bulb will output approximately 800 lumens, while a 13W LED will output 1000 lumens.
Let's calculate the efficiency by dividing the luminous flux by the power required to power the lamp: incandescent lamps – 17 lm/W, energy-saving lamps – 62.5 lm/W and LED lamps – 76.9 lm/W.
Heat transfer comparison
Heat dissipation is an important factor for many, especially for buyers large quantity lamps for large objects.
If you are purchasing lamps for your home, you should also consider this factor, regardless of the scale of the installation.
Tests show that 100W incandescent lamps heat up to 168.5 degrees, energy-saving lamps heat up to 81.7 degrees, and LED lamps heat up to 30.5 degrees. LED lamps have by far the lowest incandescent temperatures and risk of fire.
Average lifespan comparison
LED lamps have a service life of more than 50,000 hours, but in most cases they burn much longer.
This excellent result compared to 8,000 hours for energy-saving lamps and 750 hours for conventional incandescent lamps.
Many large commercial companies are switching to LED bulbs only because they have huge replacement costs for incandescent bulbs due to their low lifespan.
Environmental impact
Energy-saving lamps cannot be recycled like typical incandescent or LED lamps because they contain mercury, which will leach into the soil and water if they are simply thrown into a landfill.
They also emit greenhouse gases when used and disposed of. LED and incandescent bulbs are safe, and many of the materials in LED bulbs can be recycled.
