Energy-saving lamps assortment and characteristics. Technical characteristics of energy-saving lamps

The main advantage of LED light sources is significant energy savings. You can get tangible and desired results using the products of the online store.

Energy-saving fluorescent lamps, which have already become familiar to many, are gradually becoming a thing of the past. It is being replaced by lighting equipment of a fundamentally new type, with different light and quality characteristics. Modern LED light sources have a whole range of advantages over their predecessors. This applies to light output, energy consumption, service life, environmental friendliness, fire and mechanical safety. The "minuses" that make their implementation difficult include the higher cost and the conservatism of a certain part of the population.

To overcome doubts, it is enough to turn to table of correspondence of power of LED lamps characteristics of light sources of the previous generation.

Table comparing characteristics of lamps: incandescent, halogen, energy-saving fluorescent and energy-saving LED lamps

The table of correspondence between the luminous efficiency of energy-saving (fluorescent) lamps and incandescent lamps corresponds to

LED and Incandescent

It should be noted that the tabular figures are averages and may differ for. However, the conclusions are clear. Traditional, but obsolete, uneconomical light bulbs lose significantly. The given table of correspondence of the power of LED lamps, even taking into account the inevitable error, convincingly proves the advantages of the new generation systems. To this must be added a long service life, due to their design features and providing a quick and repeated payback. Analysis of tabular data, simple calculations show: the present and the future are behind the LEDs!

Today the market offers a wide range of light sources: LED, well-known and familiar incandescent lamps, halogen and compact fluorescent lamps. The last of these performances are also called energy-saving, as they have successfully replaced their counterparts with an incandescent filament due to their low energy consumption.

In addition, there are models of such lamps with an Edison base (E27). For comparison, a special table of correspondence of the main technical characteristics of different types of light sources (luminous flux, power) has been created: energy-saving fluorescent, LED, incandescent.

Differences in design

The most popular type of lamp at all times is with a tungsten filament located inside a transparent or opaque bulb. These are versions with a filament that are equipped with an Edison E27, E14 or E40 base. The glow produces an electric current passing through the tungsten filament. This is the most affordable option.

Only he has quite a few minuses, which makes him gradually switch to other lamps, for example, fluorescent energy-saving ones.

halogen type device

In particular, the service life of analogues with an incandescent filament is only 1,000 hours, and besides, they are characterized by low efficiency (most of the energy is converted into heat).

Slightly more efficient halogen lamps. Their design also provides for a tungsten filament, as in an analogue with an incandescent filament. But inside the flask contains bromine or iodine. The chemical processes that take place between these elements and tungsten atoms contribute to extending the life of such a lamp (up to 4,000 hours).

An even more perfect option is energy-saving light sources. The power of compact fluorescent bulbs is noticeably lower than that of their incandescent and halogen counterparts, and the radiation intensity provides no less bright light.

In the design, the main elements are electrodes; when current is applied, an arc discharge is formed. UV radiation appears due to gaseous filling (inert gas, mercury vapor), and it is visible that the phosphor deposited on the inner walls of the flask makes it visible.

The design of the diode lamp

The market also offers LED lamps. Their functioning is based on light-emitting diodes, the type and quantity of which determines the intensity of the light flux. In terms of power, these are the most economical versions. The range of models of each type of light source includes options equipped with an Edison E 27 base, which allows them to be installed instead of analogues with an incandescent filament.

Overview of lamp specifications

When choosing, it is the parameters of the light source that are key, thanks to which it is easy to determine whether the selected lamps meet the operating conditions (room area, installation height, ambient temperature, sufficient brightness level, etc.).

Colorful temperature

The main technical characteristics of different types of light bulbs:

  1. Power, W). Determines the power consumption level of the light source. It is recommended to pay attention to economical designs, especially if lamps are selected for a room where the light will be turned on for a long period (kitchen, living room, children's room).
  2. Luminous flux intensity (lm). This parameter allows you to determine before buying how bright the light from the device will be. If we consider LED versions, then the luminous flux will not depend on power. This relationship between the parameters is observed in luminescent energy-saving, halogen and analogues with an incandescent filament.
  3. Colorful temperature. Depending on the value of this parameter, you can get cool blue (more than 5000 K), warm yellow (less than 3000 K) and neutral light (4000 K). Based on the value of the color temperature, you can determine the level of comfort from the glow of the lamp (the higher the value, the worse the light is perceived).
  4. Plinth type. In different models, holders can be provided in two variations: pin and threaded (E 27, E 14, E 40). In everyday life, it is easier to use lamps with an E 27 base. This is the most common type that light sources with an incandescent filament are equipped with. Variants with an E 14 base are smaller, and E 40, on the contrary, are used in the design of light bulbs with a large bulb. Today, you can pick up versions with an E 27 base in the assortment of models of each type of set source.
  5. Life time.

Additionally, for each type of lamp, other characteristics should be considered.

For example, when choosing LED versions, the type of diodes used and their number are taken into account. Energy-saving (compact luminescent) analogues are selected according to the shape of the bulb.

Comparison of different types of lamps

To determine the best option for a light emitting element, it is necessary to conduct a comparative analysis of the main parameters of the varieties of interest. Considering that halogen versions are similar in power level to incandescent lamps, they were not included in the correspondence table:

Comparing different types of light sources

It is the ratio of the luminous flux and the load level that allows you to choose the most suitable option in terms of the totality of characteristics. It is also necessary to take into account the configuration of the room, since a lamp with a high radiation intensity does not always meet the requirements for illumination of a low room with a small area.

Overview of positive and negative traits

Power plays the main role. The comparison table showed that energy-saving and LED lamps are the best. In addition, the load level of the light emitting element does not affect the degree of intensity of its emission. This means that it is possible to save up to 80% of electricity, and without a minimum loss of lighting quality.

The brightness level of light sources of the same power value (for example, you can take 4 W) is higher for LED versions (300 lm). This option heats up less than others. In addition, diode-based lamps are more durable. But the operation of luminescent analogues is not completely safe, since they are equipped with a glass flask, which also contains mercury vapor.

In terms of service life, again, diode-based versions are in the lead (an average of 50,000 hours). Slightly behind them are energy-saving lamps (9,000-12,000 hours). Analogs with an incandescent filament also lose in this parameter (1,000 hours).

The advantage of each of these light emitting elements is the type of holder used - they are all equipped with an E 27 base.

The main disadvantages of fluorescent compact and LED options are the rather high price. But if we take into account the long service life of both varieties, we can talk about savings when buying them, since you do not have to change the lamp often. In addition, both options are characterized by neutral white or cold light. Therefore, it is generally accepted that these types of light bulbs create less pleasing to the eye illumination of the room. But progress does not stand still and gradually the range of light sources is expanding, which means the appearance of glows of different color temperatures.

Many of you switched from incandescent sources to energy-saving light bulbs a long time ago, and now you are thinking about LED ones. The rationality of the transition must be calculated for each case separately and depends on the mode in which it is used. It is especially not recommended to install energy-saving lamps where they operate in a short-term mode. They kindle slowly, when it flares up at full power, then you already leave the room and turn off the light.

Energy-saving lamps types and price

Energy-saving lamps are called compact fluorescent light bulbs, abbreviated as CFLs. The abbreviation will be used throughout the text. By design, it is a conventional fluorescent light source in a more compact format. The power supply unit is installed at the base of the case near the base; for cooling, small holes are made through which air circulates.

  1. shape in the form of a spiral, circle, square, horseshoe;
  2. base E14, E27, E40;
  3. with a flask in the form of a pear, a candle, a ball;
  4. the ability to adjust the brightness, dimming.

If you decide to switch from CFL to LED, you will run into a common problem. For LEDs with an E14 base, the luminous flux is no more than 600lm, due to the fact that the dimensions are limited. In this case, the power is 6-7W, it is almost an analogue of a 60W incandescent. To illuminate the room where the CFLs used to be, LEDs may not be enough. The illumination will be lower than expected, and it should be with a margin, given the degradation of the LEDs. Even the Chinese do not have powerful ones, although they write in parameters from 1000 to 1500lm, which is 2-3 times too high.

Only recently have LED E14 800-900 lumens appeared, power consumption 10W produced by X-Flash. But now they are in short supply, E14 at 10W are sold out immediately, they are not even often on the manufacturer's website.

The main disadvantage of CFL will be:

  1. slow ignition up to 10 minutes;
  2. decrease in light output at low temperatures.

How to choose

To choose the best energy-saving lamps, you need to know 9 basic parameters, half are similar to diode ones.

Main characteristics:

  1. rated power - power consumption;
  2. power factor - the ratio of active and reactive;
  3. luminous flux - the brightness of the source;
  4. color temperature - 2700K warm white or neutral white 4000K;
  5. color rendering index CRI - color rendering of objects;
  6. warm-up time - the period of time after which it shines by 60-80%;
  7. ignition time - the time required for ignition;
  8. service life - the number of hours after which the brightness will drop by 30% of the initial;
  9. number of switching cycles.

The easiest way to choose the best ones is by brand, it must be well-known. If you hear the brand name for the first time, then it is better to refuse. The bigger the brand, the more they worry about quality. When you compare energy-saving in price with cheap diode ones, then in terms of service life they will not work much longer than CFLs. A good LED costs from 200 rubles.

Consider the installation location, if on the street or in the entrance, there will be many who want to drag it or break it. Therefore, in the entrance I put filament LEDs with a broken bulb, they cannot be unscrewed without a tool. If you try to unscrew it with your hands, you will break the LEDs, and it’s not very noticeable in the ceiling.

Power Compliance

energy saving lamp power table

A feature of energy-saving lamps E14, E27, E40 is the lack of the possibility of dimming, dimming. To maintain the glow requires a constant high voltage. But looking through the Osram website, it turned out that they have models with brightness control.

The table shows the correspondence between LED and incandescent.

Table of power and correspondence of incandescence.

CFL incandescent LED Stream of light, Lm
5w 25w 3w 250
9w 40w 5w 400
13w 60w 7w 650
15w 80w 9w 900
20w 100w 14w 1300
35w 150w 20w 2100

To simplify the calculation of the incandescent analogue, use a factor of 5. For example, you have a 9W CFL, multiply 9w by 5, it will turn out to be an analogue of a 45W light bulb.

Luminous flux and power

..

As elsewhere, when choosing, look not only at the price, but use the rule: "cheap can not be good, no matter what the manufacturer promises." Too often I encounter deceptions from stores and from manufacturers. The economic situation in Russia in 2016 is difficult, therefore, in order to keep the business, many begin to deceive the buyer, so that sales do not fall.

An example would be the ASD brand, which exaggerates the power and luminous flux of its lamps and fixtures. Their products are cheap, and in combination with high performance and service life are popular. It turns out such a situation, who lied more, he sold more. At an equal price, you choose where they promise more.

Table of luminous flux and power.

Philips specification example

Life time

Now a large number of energy-saving lamps are imported from China. They are looking for a factory for the production of light bulbs in China, put their own brand on them and sell them in Russia. To sell, a brand does not need to understand them and have its own laboratory. The Chinese take advantage of this by slipping worse LEDs with worse parameters. Then it turns out that the manufacturer promises some parameters, but in fact the technical characteristics are different.

  1. Chinese up to 3,000 - 5,000 hours, although they promise up to 10,000 hours;
  2. branded 6.000 – 10.000 h.

The probability of failure fromOsram.

Domestic brands send lighting equipment to me for tests, some Chinese are very deceiving and do not admit to deception. They slip fake test results as proof they can convince the layman. After looking at the test results, it was clear how they were deceiving.

Cheap lamps of little-known domestic brands work much less than branded energy-saving lamps from Osram, Philips and other well-known ones. Cheap ones have lower quality components in the power supply. In addition, it gets very hot, shortening the service life. You probably saw blackened ones, in the part where the power supply is located.

The build quality also affects the service life, Chinese manufacturers save on everything, even where it is impossible to do so. Therefore, instead of the promised 15,000 hours, the cheap one works 5,000 hours, that is, the characteristics are overestimated. Branded Philips and Osrams are guaranteed to work for the specified period of time, abroad the requirements for light bulbs are more stringent.

Philips has models with up to 10 thousand hours of operation, but their stage is correspondingly much higher. Indirectly, it can be determined by the warranty period. If the warranty is 1 year, then do not expect a long period of work. A guarantee of 3-5 years is given only for high-quality

Why blinking or blinking

Many of you ask why does an energy saving light bulb blink when the switch is turned off or when the light is off? You most likely have a backlit switch. A small current passes through the backlight, which charges the energy-saving power supply. As soon as there is enough energy in the power supply, it flashes. Then the process is repeated.

So that it does not blink or blink, you will need to remove the backlight in the switch, this is the easiest and best way. There are other options for installing a small load in parallel so that the current goes to it. Most LEDs have the same problem and are also solved.

Which light bulbs are better LED or energy saving

In terms of efficiency, LED and energy-saving devices differ on average by 2 times. To get an analogue of incandescence at 100W at 1300 lumens, you will need:

  1. diode for 15W;
  2. energy saving at 25W - 30W.

The luminous flux depends on the quality of the components used and on the amount of phosphor deposited on the walls of the spiral inside. The manufacturer likes to indicate the service life of LEDs as the life of the light bulb, in fact, these are completely different values. therefore it is difficult to compare different types of light sources.

Circuit and power supply

The energy saving scheme is the same as that of a conventional 36W Armstrong fluorescent tube. It is powered by a starter that starts the light with high voltage. The power supply is a conventional starter, such as an electronic ballast (electronic ballast).

Requires a little modification to make. At the output, a transformer with a stabilizer is connected. The most difficult thing is to find or select a suitable transformer. If it does not fit, then burn the entire structure. It will still take time to adjust. If you do not have good amateur radio experience, then there is no particular chance to assemble it correctly.

Often such power supplies are of low reliability, because they are exposed to a lot of heat that even the plastic turns black. Many people still have outdated equipment, such as VCRs, so it’s easier to take a ready-made unit from household appliances, from faulty or outdated ones.

Even with my experience, I am periodically exposed to high voltage from 220V that even screwdrivers melt. Feelings are not the most pleasant, so it’s better not to climb into high-voltage blocks on your own. Even a non-discharged capacitor can treat you well.

Important indicators of energy saving lamps

To choose the right energy-saving lamp (ECL) for your space, it is important to know the selection criteria for the main technical characteristics of energy-saving lamps.

The main parameters of the ESL include;
lamp dimensions. Of course, you need to pay attention to the size of the lamps, since in general ESLs are larger than incandescent bulbs and may not fit in the lamp shade;

plinth type these lamps are the same as incandescent ones - these are E27 type socles (27 mm in diameter), the most common, E14 socle (14 mm in diameter), they are mainly intended for installation in chandeliers, multi-track lamps. Socle type E40 is designed for lamps installed in spotlights;

lamp glow color has a color gradation from a cold white glow to yellow.

Bases of energy-saving lamps E 14 (left) and E27 (right)

Technical characteristics of energy-saving lamps

The main characteristics of ESL include;

Power consumed by the lamp. For private use, lamps with a power of 5 to 100 W are purchased, and for industrial needs 5 - 250 W.

When choosing an ESL, you need to know that they have a luminous efficiency 5 times higher than incandescent specimens. For example, a 20 watt ESL can replace a 100 watt filament. The package indicates the power of the replaced incandescent lamp;

Table of characteristics of energy-saving lamps - power comparison

Lifetime ESL is 8 times higher than a conventional incandescent light bulb, which is equal to 1000 hours of operation under ideal conditions. The increase in service life is achieved by a different principle of lamp operation, in which the filament consumes much less current. These lamps do not need a high wattage to ignite an inert gas, which significantly increases their service life. The product's service life is indicated on the packaging;

Light flow determines the quality of the lamp, the higher the quality, the higher the luminous flux. The measure of luminous flux is lumen (lm) and is also indicated on the packaging

;- Light output ESL is an indicator of lamp efficiency, which for incandescent bulbs has a value of 10 - 15 lm / W, and for ESL 50 - 80 lm / W, which is much higher, but not yet ideal. According to this parameter, there is a system for classifying electricity consumption by lighting sources. These 7 gradations are denoted by the letters A - G, where classes A and B are occupied by energy-saving lamps with lower power consumption;

Colorful temperature is a measure of the color of the lamp. In ESL, the color of the glow is determined by the type of phosphor and is measured in Kelvin (K). For incandescent lamps, the color temperature is in the range of 2703 - 3000 K - this is the color of the glow of the sky at sunset. Day or natural color has a color temperature of 4000 - 4200 K. The cool color range is in the range of 6000 - 6500 K.

Such a bright white color of the glow causes eye fatigue and the main use of these ESLs is the illumination of streets and squares. The power indicator of the lamps does not affect their luminous flux. With the same power ESL, the luminous flux can be different. Also, new designs of energy-saving lamps can have lower power and higher luminous flux, while older models with higher power have lower luminous flux;

Color rendering index shows the natural color of objects when illuminated by different ESL. This indicator ideally has a value of 100 Ra. For a comfortable perception of objects, the color rendering index should be within 80 - 100 Ra. A lower index indicates poorer color rendering properties.

Labeling of energy-saving lamps

The designation of energy-saving lamps for Russian models has a letter meaning, which indicates that;
- L is luminescent;
- B - white glow lamps; - TB - glow color is warm - white;
- D - day color;
- C - illumination with improved color rendering;
- E - means good environmental friendliness.

Characteristics of the luminous flux and color temperature of energy-saving lamps. Labeling of energy-saving lamps

In deciphering the international designation, the first digit reflects the color rendering index, while the others are indicators of the color temperature multiplied by 100. For lamps with a good color rendering index (high-quality phosphor), the first digit should not be lower than 8. For private use, the color temperature within 2700 and 3600 K, and the marking in numbers should be 827, 830, and also 836.

The use of incandescent lamps has long been irrelevant. They were replaced by a new invention, which became very popular even despite the higher cost. These lamps are called energy-saving or simply "housekeeper".

The main feature of such elements is low consumption of electrical energy. It is this property that led to their popularization in all countries of the world. In some states, with the advent of "housekeepers", bans were introduced on the use of incandescent bulbs.

But if the design of an ordinary light bulb is simple and understandable, then energy-saving ones are a mystery to many. This article will help you find out if energy-saving elements are really so useful and economical.

Application area

When energy-saving lamps appeared, they were more often used in office premises. Over time, they began to actively fill the markets and electrical stores. This led to the fact that the cost of "housekeepers" decreased and increased their availability for all categories of the population.

Energy-saving lamps are a great way to save electricity, which rises in price every year.

Having tested energy-saving light bulbs in action, people are convinced of their effectiveness and try to switch only to this type of lighting.

Basically, these lamps are used in residential areas. Less commonly used in cellars, hallways and corridors, as well as to illuminate the territory of a private house at night.

The use of such lamps is also widespread in the housing and communal services sector. On staircases, where ordinary lamps often burn out, it is very convenient to use the “housekeeper”. The service life allows you to use them for a long time. Even if a defect occurs in the device and the lamp burns out before the specified period, it can always be replaced under warranty. Every year more and more apartment sectors are switching to energy-saving types of lighting.

How to choose

Manufacturers produce "housekeepers" with different parameters and quality of the product.

When choosing an energy-saving lamp, pay attention to its size, otherwise it will not fit in a chandelier or lamp.

First, let's choose the optimal form:

  • spiral;
  • U-shaped;
  • semi-spiral.

Lighting and operating modes for all types of lamps are almost the same, the differences are only in the form of their manufacture and cost. Spiral is more expensive due to the complexity of the design.

“Housekeepers” differ in power consumption of electricity. The power range ranges from 3 to 120 watts. It is worth paying attention to this, because the brightness of its glow depends on the power. If it is necessary to illuminate a large room, then high-power lamps are used.

Bulbs are produced with different diameters of socles, which have different applications. Some are designed only for wall lamps, others for ceiling chandeliers and spotlights.

Quality directly depends on the manufacturer. It is not recommended to purchase Chinese lamps at a low cost.

Energy-saving lamps, various in shape and color

The service life also plays an important role in the selection. If the warranty for the lamp is 1 year, then the “housekeeper” has low quality indicators. Normal manufacturers give a guarantee for their products up to three years.

When heading to the electrical store for an energy-saving lamp, it is important to remember the following:

  1. The form;
  2. Plinth type;
  3. Power;
  4. Life time;
  5. color rendering;
  6. Firm manufacturer.

Advantages

What are the advantages of "housekeepers"? These include the following important indicators:

  1. High light output properties. "Housekeepers" allow you to emit a luminous flux many times greater than conventional lamps. Profitability also lies in the fact that the maximum consumption of electricity is converted into a luminous flux.
  2. Long service life. Medium quality light bulbs can burn continuously for up to 15,000 hours.
  3. Variety of color streams. Incandescent lamps do not have the ability to control the color of the glow. "Housekeepers" come in three types of glow: warm, cold and daylight.
  4. Minor release of thermal energy. This property suggests that the energy consumed goes precisely to the formation of a luminous flux. Weak heating of the device allows it to be used in floor lamps made of fabrics and plastics. Conventional light bulbs heat up the fabric and may cause a fire.
  5. Soft and even distribution of light rays. The light spreads around the room with the same glow.
  6. Low power consumption at high lighting rates. Savings can be up to 75% compared to standard incandescent bulbs

“Housekeepers” save the financial resources of users

disadvantages

Along with such quality indicators, energy-saving lamps have their drawbacks. They are as follows:

  1. Long time for the maximum luminous flux to occur when the lamp is turned on. This time ranges from 3 seconds and sometimes up to 2 minutes. Especially this phenomenon is often noticed when the “housekeeper” is operated in a cold room.
  2. Energy-saving lamps emit rays that are harmful to people suffering from skin diseases. The operation of the light source for such people is not allowed at a distance closer than 30 cm. The higher the power of the lamp, the more ultraviolet they emit.
  3. Sensitivity to voltage drops. With a decrease in the voltage of the 220 V network by 10%, they are able to turn off on their own. They do not turn on at a low voltage of 195 V. Lamps must not be used in luminaires with dimmers.
  4. Low frost resistance. It is impossible to turn on and operate an energy-saving lamp in cold weather at sub-zero temperatures (-15 and below).
  5. The content of harmful substances in the structure: mercury and phosphorus. These substances are not dangerous when glowing, but are dangerous if the lamp breaks. After unsuitability, they require special disposal.
  6. Intermittent flickering. This is not normal and indicates a possible failure in the near future.
  7. High price. To transfer the entire house to this type of lighting, considerable financial costs will be required.

Mercury vapor hazard

Mercury is a chemical reagent that is one of the most dangerous for humans. Almost all energy-saving lamps have mercury vapor in their design, or rather, inside a glass bulb. Their content is 3-5 mg, which is a lethal dose for humans. During the operation of the lamp, this mercury is absolutely harmless, it is not released from it and does not affect the human body in any way.

If the lamp breaks, then the risk of poisoning a person with mercury vapor increases.

If an energy-saving lamp breaks, you should immediately ventilate the room and dispose of it.

Measures taken in time will not entail any dangerous consequences. It must be properly disposed of. After all, the industry produces millions of energy-saving lamps a day, and there are very few collection points. In this regard, people throw away lamps together with household waste, which is unacceptable and causes enormous damage to the environment!

If in a locality it is not possible to hand over energy-saving light bulbs to a recycling company, then it is better to choose those that do not contain hazardous substances.

A few words about manufacturers

Since the advent of energy-saving lamps, the number of manufacturers of this light source has been growing every day. The most demanded (in terms of price indicators) are products made in China. The cost of high-quality elements is an order of magnitude higher than Chinese ones, but the long service life and high technical parameters pay off the costs.

Among the most popular and high-quality manufacturing companies are the following:

  • OSRAM;
  • Philips;
  • Photon;
  • Maxus.

These brands have really excellent technical indicators. Manufacturers give a guarantee for their products up to 3 years. Production bases are located in Germany, Italy and other countries.

Firms producing energy-saving lamps of medium quality:

  • Space;
  • Navigator;
  • Wolta;
  • Nakai.

Manufacturers of economy class products (quality level - satisfactory):

  • electrum;
  • Volta;
  • deluxe;
  • sunluxe.

Manufacturers of high-quality energy-saving lamps do not use liquid mercury in the manufacture of flasks, but a special type of amalgam alloy. In this alloy, mercury is in a bound state. This allows her, when the flask is broken, not to dissolve in the air, but to remain in a bound state.

Main technical parameters

Energy-saving lamps consist of a base, a bulb and a starting device. Bulbs of lamps are filled with vapors of mercury or inert gas of argon. The white matter on the glass of the flask is the phosphor. It is also used in fluorescent lamps.

The principle of operation of such lamps is based on the supply of high voltage to the flask with vapor. The voltage is increased by means of an installed starting device inside the plastic shell of the lamp.

High voltage causes the continuous movement of electrons. These electrons collide with the mercury atoms and produce an ultraviolet glow inside the bulb. Ultraviolet passes through the phosphor and causes a glow that is perceived by human vision.

The principle of the formation of visible light in energy-saving light bulbs

The main technical parameters of the “housekeepers” include:

  • power;
  • Colorful temperature;
  • light output;
  • types of plinths.

Power

This is an important indicator when choosing an energy-saving lamp for lighting a room. “Housekeepers”, when consuming low power, are able to emit a luminous flux 80% higher than that of incandescent lamps. can be replaced with an energy-saving one, with a power of 10 watts.

Below is a table of the ratio of the power of incandescent lamps and "housekeepers" with the number of lumens they produce.

Comparison of the power of lamps with the luminous flux emitted by them
Power of the "housekeeper", W Incandescent lamp power, W Luminous flux, Lm
5 25 220
8 40 420
12 60 720
20 100 1360
30 150 1900
45 225 2600
65 325 3590
85 425 4875
105 525 5985
120 600 7125

The table shows how much you can save on electricity if you use energy-saving elements.

As mentioned above, energy-saving lamps can emit three different types of glow, depending on the temperature of the radiation:

  1. Warm radiation has a glow temperature of 2700 degrees Kelvin. Warm light is suitable for rooms where there is no need for eye strain. Best for bedroom and kitchen.
  2. Daylight - 4200K. It will be an excellent solution for lighting children's rooms and living rooms. This glow is closer to natural light.
  3. Cold - 6400 degrees Kelvin. For office spaces where long-term eye strain is required, lamps with cold light emission are suitable.

Visualization of the “color temperature” characteristic

If the eyes get tired of the light that the device emits. This is evidence that the color temperature of the lamp was incorrectly selected for this room.

Light output

Luminous efficacy is the ability to propagate a luminous flux, measured in lumens Lm, and directly dependent on the power of the lamp. The more powerful the energy-saving lamp, the faster and more intensively the electrons inside the bulb move, interacting with the atoms. A table characterizing the amount of light flux from power is presented above.
