Arranging lighting in an apartment and in your yard is quite a difficult task. With so many different light source models out there, choosing one can be lengthy and really complicated. After all, if you choose lighting that does not suit your requirements, you will remain dissatisfied, and you may have to spend extra money for replacement.
In this article we will help you choose powerful energy-saving lamps for you. Let's talk about the principle of their operation and how they are designed. Let's write down what types exist and compare them with the most popular models, such as halogen, incandescent and LED. We will describe the process of selecting a device and tell you which manufacturers are best to choose.
The structure and principle of operation of the lamp
Often the same. They consist of a base - a base. It can be of different types, but the main varieties found are E27 and E40. It is equipped with two contacts for connection, the plus is located on the back in the form of a point, and the minus is directed towards the entire base.
Also, the walls are made in the form of a spiral thread, making it possible to screw the base into a standard e27 and e40 socket.
The outer visible part of the lamp is represented by a glass spiral, which is filled with special vapors, which ignite when current is applied and the entire system is triggered. Usually the tube contains mercury vapor, which emits light. Due to this design feature, llamas cannot be thrown away, but must be disposed of in special receptacles.
The curved spiral design is due to the fact that thanks to this shape the lamp is much more compact with a rather long glass tube. This was done in order to significantly save space and allow the devices to be used in standard home luminaires.
A special electrical circuit is installed in the base, which is responsible for ignition and stabilization of the device. It also sells the current necessary for the lamp to function. You can call such a component a ballast mechanism, but simply it is called electronic ballast.
This device works according to the following principle. After the current supply starts, it flows to the electrodes and heats them to the required temperature. After achieving the desired heating, the process of thermionic emission occurs. The electrodes then begin to release a stream of electrons, which collide with the atoms, which in turn begin to emit light.
But mercury by its nature emits only ultraviolet light, which is invisible to the human eye. Here the phosphor comes into play, converting it and producing a visible spectrum of light. The thermal indicator of the light of such lamps ranges from 2700 to 6500K. It depends on the type of phosphor.
Such a device is capable of emitting its own visible light, but its share is only two percent, the rest of the light is ultraviolet, which interacts with the phosphor. The visible part of the light does not participate in the transformation in any way and remains unchanged.
A short comparison with analogues
The technical characteristics of energy-saving lamps differ significantly from other similar devices. Therefore, to make sure whether you need exactly such a light bulb, you should compare it with similar analogues.
For comparison, it is worth choosing the most common light sources, such as halogen lamps, LED and incandescent lamps.
Very often, manufacturers like to compare a fluorescent lamp with an incandescent lamp right on the packaging. By adding a visual comparison of some technical characteristics, such as power, or adding flashy names that outline the essence of the difference itself.
We will compare them according to the following criteria: power, emitted light flux, required voltage, durability, type of base. The power of light bulbs is completely different, and it is generally accepted to compare it with the power of incandescent lamps; this is a kind of constant constant.
Halogen lamps have approximately the same performance as a similar incandescent light bulb. LEDs, on the contrary, have up to ten times less power. Energy-saving lamps have a power rating of approximately 15 watts, which is equivalent to a 60-watt light bulb.
Comparing different types of lamps
The average 15-watt light bulb is capable of emitting about eight hundred lumens. The radiation indicator of halogen lamps will be several times less. LEDs, with such power, will be able to produce more than one and a half thousand lumens.
All listed devices are capable of operating from a 220 volt network. Only LED lights require additional equipment, since their standard operating voltage is 12 volts. But you can purchase a device with a built-in transformer to create the required voltage indicator.
Base E27 and E40 have incandescent lamps and LED fluorescent devices. Halogen ones require the use of a specialized lamp with a special connection diagram. Although there are options with a regular base E27 or E40.
The devices differ significantly in terms of service life; having the same power, they can last the following number of hours:
- Incandescent lamp - on average 1000 hours.
- Halogen - about 2-3 thousand hours.
- Luminescent devices - 10-15 thousand working hours.
- LED – more than 50,000.
Based on this, it can be assumed that energy-saving light bulbs have fairly good performance in comparison with their counterparts. They do not compromise on it at all and will be able to satisfy your needs in full.
In terms of popularity and with a more in-depth analysis of their characteristics, energy-saving light bulbs take an honorable second place after LED ones.
Choosing an energy-saving lamp
Having chosen the right device to illuminate your room, you will be completely satisfied with your choice and it will suit all the wishes and requirements for the place where you install the light bulb.
What indicators should you pay attention to:
- The first thing to note is the installation location. Not every room will have such light bulbs that can function properly. The same applies to the lamp; if installed in the bathroom, it is necessary to select a waterproof lamp.
- Requirement for luminous flux power. Depending on your personal wishes and the need to create a certain level of light, you should choose the power of the light bulb. For example, for the work area, you should choose more powerful devices to ensure the required luminous flux. For a bedroom or table reading lamp, a low-power device is sufficient. If you want to fully illuminate your yard, then buy a high-power fluorescent lamp.
- The type of socket in which the light bulb will be installed. You should select a light bulb so that it is equipped with an E27 or E40 base; these two options are the most common in home lamps. The e27 and e40 sockets are compatible with the e27 and e40 sockets, respectively.
- When choosing a device to illuminate a home nursery or aquarium, you should choose a lamp specifically for such purposes. There are also varieties for indoor and outdoor use. They have varying degrees of protection from dust and moisture.
Which manufacturer is better
You shouldn’t sift out all the cheap manufacturers at once and stop only at expensive brands. As a rule, absolutely everyone has a share of marriage. And whether you will fall into this unpleasant percentage by paying a lot of money or a meager amount is completely unknown and unpredictable.
Less popular and budget brands use cheap materials in their devices. This is precisely due to the low price. But it is not a fact that they all produce low-quality products. As often happens, such devices work no worse than their expensive counterparts, but their service life may be shorter.
Until recently, energy-saving devices were not widely used indoors, as they were manufactured in the form of tubes of different lengths. It was difficult for an ordinary user to install or change such models, compared to a conventional incandescent lamp. Today this is an improved device for a fluorescent lighting device. Let's take a closer look at what energy-saving lamps are (types and prices will help you make the right choice for your room).
Read in the article:
Categories of lighting fixtures, types of bases
There are 2 types of models:
- LED
- luminescent.
If we talk about light output, then LED designs have much more.
Types of LED lamps and applications
LED (light emitting diode) is a visually ordinary bulb with a semiconductor crystal. The range depends on the chemical semiconductor composition. In modern technology, this is a new solution.
Classification:
- Type of base.
- Application area.
- Type of LED used.
Let's look at LED models by area of application.
Street lighting fixtures
Widely used in illumination of large swimming pools, public buildings, pedestrians and other public places.
Various decoration methods using smart RGB lighting devices are also widely used.
LED for home and office use
This type can completely replace all categories of previously used models: conventional incandescent lamps; fluorescent and halogen.
Visually they are no different from their predecessors and have a similar base.
LED spotlights
This model is assigned to a separate class. Until today, quartz light fluxes have been used in spotlights.
Due to technical characteristics and differences in photometry, it is impossible to directly replace quartz lamps with LED models. Therefore, floodlights are designed specifically for the LED light source.
LED in industry
This direction is widely used in factories, warehouses and production facilities.
Distinctive features: ideal luminous flux; highest power and IP rating protection.
Models designed for growing plants
Note! Such models sometimes use programming capabilities.
How are caps classified?
The base is the part of the lighting fixture that is in contact with the power supply.
Types of energy-saving lamp bases are divided into two groups:
- Screw-type, marked with the symbol “E”.
- Pin "G".
Let's take a closer look in the table at how bases are classified:
| Types of base | Description |
|---|---|
 E27 Regular classic model with thread | The base is suitable for chandeliers and lamps |
 E14, this is E27, only with smaller threads | Used in modern lighting devices. Models “candle” and “minion” are produced with a base. |
 GU5.3, similar to the base model of halogen | Such devices are used in LED lamps and do not require design changes |
 GU10 | The model can be found in the kitchen area, where a hood and lighting are used |
 G4 base with two wires | Used in small light bulbs |
 G9 (pin) | The base is the most convenient when installing or replacing the flask |
Energy saving lamps and LED lamps: comparison with predecessors
In order to obtain a complete amount of information about each model, you need to clearly familiarize yourself with the performance characteristics and make a comparison.
Note! In order for the comparison to take place with maximum accuracy, we determine the level of luminous flux of the room (800 Lm).
This is about a regular 75W incandescent model. Now let's give an example with 4 devices, with the same level of illumination.
Comparison table for energy-saving lamps: technical characteristics of incandescent, halogen and fluorescent devices:
| Types/names | Heating degree | Light flux, lm | Power, W | Payment per year/RUB (20 devices) |
|---|---|---|---|---|
 Incandescent lighting fixture | High heat | 600-700 | 75 | 11000 |
 Compact fluorescent lamp, energy-saving model | Medium heat | 600-700 | 15 | 2200 |
 LED | Doesn't heat up or break | 800 | 10 | 1450 |
 Halogen | Gets very hot and very fragile | 700 | 45 | 6600 |
Based on the data in the table, we can summarize that the leading place is occupied by.
Power consumption
The data shows that for different types of lamps, with the same illumination, the luminous efficiency varies greatly. As for the practical issue, an LED lighting device consumes almost 8 times less energy, which affects costs.
Note! A fluorescent lamp, for all its savings, is still less economical.
Saving
Let's do a little calculation:
- Price of one kW = 3 rubles.
- We will assume that the lamp burns 8 hours a day.
- We receive 2920 hours per year.
Let's calculate electricity for the year:
- Incandescent lamp: 2920×75 = 219,000 = 219 kW per hour (219×3 = 657 rubles).
- Luminescent: 2920×15 = 43,800 = 43.8 kW per hour (43.8×3 = 131.4 rubles).
- LED: 2920×10 = 29,200 = 29.2 kW per hour (29.2×3 = 87.6 rubles).
- Halogen: 2920×45 = 131,400 = 131.4 kW per hour (131.4×3 = 394.2 rubles).
Based on the calculations, it can be seen that the LED model allows us to save a significant amount.
Regular and energy saving lamp: power/table
The table shows indicators without a protective bulb, which reduces brightness by 20%.
| LED, W | Incandescent, W | Flow, Lm |
|---|---|---|
| 3 | 25 | 250 |
| 5 | 40 | 400 |
| 8 | 60 | 650 |
| 14 | 100 | 1300 |
| 22 | 150 | 2100 |
Are energy-saving lamps harmful to human health (especially for children)?
Ecology is one of the important indicators of the product. From the point of view of their data, halogen and incandescent lamps are environmentally friendly; their light spectrum is not harmful to human health. But taking into account the energy consumed, which is wasted just like that, they received a rating of 4 on a five-point scale.
Fluorescent lighting fixtures are rated 3 for several reasons:
- Energy-saving lamps flicker when turned off, which causes very tired eyes.
- The luminous flux is very weak and it is bad for vision.
- Mercury, if the lamp is damaged, can cause harm to health. Urgent disposal of the device will be required.
Note! LED lighting devices received a rating of five, as they have no disadvantages from the point of view of the environment and harm to the body.
Energy saving lamps: types and price. Are we saving or not?
In order to understand which model to choose for a particular room and save, you need to look at the average cost, service life and calculate the total savings.
Now let’s calculate the real savings of an LED lamp compared to its predecessors. The maximum service life after which the luminous flux begins to decrease significantly is 3 years, based on 8 hours per day.
Note! This adds up to 8,500 hours of lamp life. During this period, we change 12 incandescent lamps and 2 fluorescent lamps.
Let's calculate the amount for 3 years:
- LED – 300 rubles (1×300).
- Luminescent – 300 rubles (2×150).
- Lamp “Ilyich” – 360 rubles (12×30).
Then we add the amount of consumed electricity to the cost and multiply by 3 years:
- LED 562.8 rub.
- Luminescent RUB 694.2
- Incandescent 2331 rub.
Attention! If we compare a regular lamp with an LED light source, then the second one will allow us to save up to 2000 rubles. in 3 years. And that's just one light bulb!
Article
Currently, an increasingly pressing issue for many consumers is the replacement of lighting devices in order to reduce energy costs. And if until recently only fluorescent lamps acted as alternative light sources, today LED devices are increasingly being considered as such an alternative.
And in order to make it easier for the consumer to understand the issues of choice, we recommend that you familiarize yourself with the design features of energy-saving lamps and analyze the tables of their correspondence to standard incandescent lamps.
Design features of lamps of various types
As many know from physics courses, a standard incandescent lamp is a sealed bulb, inside of which there is a tungsten filament, and the passage of electric current through it causes the required glow. And although this design is not particularly complicated, a number of significant drawbacks force many users to abandon incandescent lamps.
So the main disadvantage of such devices is their low efficiency, because when power is supplied, only 10% of the energy is used for its intended purpose, and the rest is simply converted into heat. In addition, incandescent lamps have a short lifespan and cannot provide high luminous output.
If we talk about the design features of fluorescent lamps, then the principle of their operation is based on slightly different properties. Indeed, in such a device the main element is a glass tube filled with mercury vapor. Whereas the glow of the element becomes possible when plasma is formed, due to heating of the electrodes (by applying voltage to them).
As a result, the technical and economic indicators of such lamps are several times higher than incandescent lamps, but still differ from them in their increased cost. In such lamps, the efficiency reaches 75%, and only a quarter of the energy expended is spent on heating. (You can find out how to unscrew a stuck light bulb from the socket in the following information).
A real breakthrough in the field of energy efficiency can be called the use of LED lamps, because their main component is an LED matrix, which can significantly reduce energy consumption and at the same time significantly improve consumer parameters (light output, operating life, fire safety). In addition, such devices are absolutely environmentally friendly (especially important in comparison with fluorescent lamps) and can be successfully operated in aggressive environmental conditions (high humidity, vibration, etc.). Well, the only drawback of lamps made on the basis of LEDs is their cost, however, taking into account the price of energy, it is not so significant.
Technical characteristics of lighting devices
In order to make it easier for the consumer to understand the need to use energy-saving lamps, it is advisable to consider the main technical parameters that characterize lighting devices.
Device power
Shows the degree of energy consumption and is measured in Watts (W or W). Ideally, one should strive to reduce this parameter through the use of innovative lighting systems.
Light flow
Indicated in lumens (lm or Lm) and allows the consumer to know the level of light energy generated by the device. When choosing energy-saving lamps, you should keep in mind that the luminous flux tends to decrease during operation.
Glow temperature
It is indicated in Kelvin (K) and allows you to determine the color of the lamp, and most often manufacturers divide this criterion into the following groups:
2700-3300 K analogue of a standard incandescent lamp or “warm color”;
4000-4200 K is an analogue of a fluorescent lamp, which has a similar shade to natural light;
5000 K “cold tint”.
Conformity tables for energy-saving lamps
For the convenience of the consumer, we suggest that you familiarize yourself with a comparative table of technical criteria for lamps of various types.
In addition, it is advisable to consider the comparative characteristics of lamps of different groups depending on their light output.

Of course, the technical data presented are indicative and may differ slightly depending on operating conditions, manufacturer, quality of the electrical network and other factors. However, even taking into account such deviations, we can confidently say that modern lighting systems are the future.

Content:
Artificial lighting has long been firmly established in our daily lives. All kinds of light sources are used everywhere - in houses, apartments, premises, offices, industrial production facilities. Most consumers use conventional incandescent lamps with a power of 40, 60 and 100 watts. However, everyone knows that they have a very low efficiency. Only half of the electricity is spent on lighting, the other half is spent on heating the light bulb itself. In this regard, energy-saving lamps are becoming increasingly popular.
The principle of operation of energy-saving lamps
This type of lamp, despite its high cost, is becoming increasingly widespread in many areas of people’s lives and activities. These light sources are compact in size and do not require a starter to start the lighting.
An important advantage of energy-saving light bulbs is their almost silent operation and very simple connection. All of them are equipped with threaded bases that simply screw into the desired lamp. The main advantages of these lamps include high reliability and efficiency, reaching 80%.
The principle of operation of energy-saving light bulbs is quite simple. Each lamp is filled with vapors of inert gases. First of all, it is argon, neon, and in some cases krypton. Some models use mercury vapor. When electricity enters the lamp, the cathode is heated and electrons are subsequently emitted. Under their influence, ionization of the gas mixture occurs. As a result, a plasma with ultraviolet light is formed, which cannot be seen with the naked eye. Ultraviolet produces illumination of the phosphor covering the walls of the bulb. Ultimately, the phosphor produces ordinary visible light.
Characteristics
The most important indicator of each energy-saving light bulb is its low power consumption. Almost all the received power is converted into . There are tables to compare the performance of energy-saving lamps and conventional incandescent light bulbs. They clearly show the difference between lamps with the same light output. Thus, the difference is approximately 5 times. That is, with the same glow, a regular light bulb consumes 100 watts, and an energy-saving light bulb consumes 20 watts.
Table of power of energy-saving lamps and incandescent lamps.
The effective operation of a light bulb is determined by the luminous flux, which is an important distinguishing characteristic of each lighting device. This parameter is measured in lumens and the brightness of the glow directly depends on it.
The most important characteristic and feature of energy-saving lamps is. Modern models are represented by threaded and pin options. Some designs have sealed contact and may be non-standard. In any case, each base must be selected according to the cartridge.
Table of light parameters
One of the parameters characterizing a light bulb is color temperature. To measure it, there is a special Kelvin temperature scale. First of all, the degree of whiteness of the illumination emitted by the lamp is determined.
The main color temperatures include the following:
- Warm white, with an indicator below 3000 K.
- Neutral white (natural light), in the range of 3000-5000 K.
- Daytime white (cold light) is over 5000 K.
In living spaces, it is recommended to use soothing and relaxing warm shades. For office premises, the best option would be light in cool tones. Natural light with a color temperature of 2800-3500 K is perceived best.
An important indicator is the luminous efficiency parameter, measured in lm/W. It determines the productivity of electricity and the amount of light produced by a particular light bulb. The level of illumination of any surface, measured in lux (lx), is of great importance.
The transmission of natural tones of illuminated objects is determined using the color rendering index. For light bulbs, this indicator is related to spectral radiation. Absolutely correct transmission is indicated by the Ra index. A decrease in this indicator indicates a deterioration in color rendering properties.
Other indicators
The service life of energy-saving lamps is of no small importance. Normal operation largely depends on the number and speed of switching and other design parameters. These indicators make it possible to determine all the costs that determine the economic feasibility of purchasing such devices.
Product labeling greatly facilitates the correct choice of lighting fixture. There are special tables that are recommended to be used when purchasing energy-saving lamps.
Possible malfunctions and repairs
During the operation of energy-saving lamps, various malfunctions and breakdowns may occur:
- If the voltage is too high, the capacitor may swell and leak, causing the lamp to stop working. In this case, all semiconductors will need to be replaced.
- The increased voltage caused the capacitor to break through. The device glows at the locations of the filaments. In this case, the capacitor must be replaced.
- As a result of improper operation, the luminous flux begins to be distributed unevenly. The bulb is partially sealed, and the lamp itself cannot be repaired.
- If at least one filament burns out, the lamp will stop working. The capacitor will need to be checked, and at the site of the filament break, the diode is replaced with a resistor by desoldering.
- The faulty diode thyristor also needs to be replaced.
Energy-saving lamps can be repaired only after the fault has been accurately determined and the spare parts required for replacement are available. A complete transition to energy-saving lamps provides significant savings for the family budget.
Since energy-saving lamps appeared on the markets, conventional incandescent lamps have rapidly begun to lose their positions. This is due to what comes from the very name of the product - energy saving. However, the latest scientific research has shocked buyers with the statement that energy-saving lamps are dangerous. How to choose a housekeeper, weigh all the pros and cons and come to the right decision?
Energy-saving light bulbs: pros and cons
First, let's talk about the advantages of these products.
- Energy saving occurs due to high luminous efficiency. Incandescent lamps lag significantly behind energy-saving lamps in this indicator, since more than 85% of all energy expended is spent on heat accumulation, which enters the tungsten wire. In housekeepers, the same electricity is directly converted into light.
- Continuing to talk about the pros and cons of energy-saving light bulbs, we must not forget about the durability of these devices. The average time that a light bulb can work without interruption is 6-15 thousand hours. These lamps do not contain a filament, which burns out over time. Therefore, the lifespan of a housekeeper is several times longer than the operating time of incandescent lamps.
- Energy-saving lamps allow the user to independently choose the level of illumination.
- The best energy-saving light bulbs do not overheat even at the highest power. Therefore, they can be used in tight fixtures made from materials that can warp from heat. At the same time, incandescent light bulbs can melt the lampshade, plastic accessories on the chandelier and even wires, which is very dangerous.
- Light is distributed evenly throughout the room. In the design of conventional light bulbs, light is emitted directly from the tungsten filament in only one direction. An energy-saving lamp distributes light as evenly as possible due to the fact that everything glows. Researchers note that this effect reduces the level of fatigue in human eyes.
Energy saving lamps and their disadvantages
So, continuing to talk about what energy-saving light bulbs have pros and cons, let's now focus on the disadvantages.
- The lifespan that can last directly depends on the selected mode. Energy-saving light bulbs are not suitable for rooms in which the lights are constantly switched on/off.
- The price is quite high (from 75 to 350 rubles).
- Warm-up duration. It is impossible to instantly illuminate a room with this lamp, since it warms up gradually. On average, this process lasts 2 minutes.
- The possibility of flickering, which irritates the eyes, cannot be ruled out.
- Energy-saving lamps emit ultraviolet light. Such rays are dangerous for all people because they negatively affect the skin, especially for those whose skin is very sensitive. They are strictly forbidden to be near such lamps, no closer than 30 cm. Excess ultraviolet radiation leads to skin diseases. According to studies conducted by doctors, the optimal lamp power for people with problem skin is 21 watts and below.
- These lamps cannot be used in chandeliers where light intensity control is provided. This happens due to an inappropriate design: when the voltage drops by at least 10% from the standard, energy-saving light bulbs turn off due to lack of power.
- Due to their chemical composition, the lamps are not dangerous in daily use. However, when they break, they release mercury and phosphorus into the air. Vapors of these substances from one light bulb, according to research by scientists, can exceed the permissible limit by 20 times, from which pregnant women and children who are in the room at that moment can suffer irreparable health problems. If an energy-saving light bulb does break, the average user does not always know what to do, so there is a set of specific rules that we have given at the end of the article.
- Mandatory special disposal. Burnt out lamps are strictly prohibited from being thrown away along with all other waste.
Choosing an energy-saving lamp
Today, the market provides a large selection of products such as energy-saving products, so that the lamp suits us in terms of its characteristics and cost.
Previously, when we were choosing an incandescent lamp, our attention was most occupied by the questions: how integral is the tungsten filament, the base and what is the power. Based on the latter, we automatically began to calculate how many kilowatts the meter would show after using one such light bulb. A significantly low indicator and, therefore, a relatively small fee for its consumption are advantages for which buyers prefer energy-saving light bulbs; their price is higher, but they pay for themselves over time. Moreover, the service life of the “housekeepers” is long.
When considering the pros and cons of energy-saving light bulbs, we talked about such an important indicator as operating time. The average operating time of a fairly compact fluorescent lamp is at least 8 thousand hours. At the same time, you will need at least 8 ordinary light bulbs. In order to save your own money, you should also choose a more economical option.
The most popular are linear ones; they are quite compact due to the smaller tube diameter and low mercury content.
Base of energy saving lamps
The sockets have a standard size, so both the incandescent ones and one have E27.
E-14 type sockets are also possible for cases where the lamps have a non-standard size, smaller than usual.
Energy saving light bulbs: power
The power of energy-saving light bulbs varies within a range of 3-90 W. When choosing a lamp for your home, you must remember that the level of light output of such lamps is 5 times higher than that of conventional lamps. You can choose a lamp for a room using a simple mathematical operation: you need to divide the power of an incandescent lamp by 5 and we will understand what energy-saving light bulbs we need to buy. We will consider below how to choose this product based on other indicators.
Color index
Fluorescent lamps are developed using special technologies that allow them to reproduce different lighting levels. These colors correspond to the cold-warm range. The color temperature depends on the quantitative indicator. The higher the temperature characteristics, the closer the light produced by the lamp will be to cool tones, and the room will be filled with blue light. Conversely, a low temperature reading will fill the room with a reddish color.
This indicator is calculated as follows:
- Below 4000 K - warm shades.
- 4000-6400 K - daylight lighting.
- 6500 and above are cool shades, approaching blue.
Rules for using energy-saving lamps so that they do not blink
When considering energy-saving light bulbs, the pros and cons of these products, we cannot ignore the issue of light bulb blinking. This is bad both for the lamp itself - it burns out faster, and for the person - frequent changes in lighting have a bad effect on a person’s nerves and eyes.
Let's look at why a switched off energy-saving light bulb blinks and how to deal with the possible problem of this phenomenon.
- From a safety point of view, switches must be connected to the phase, and not to the neutral.
- When using fluorescent lamps, switches should not have a backlight indicator.
- To prevent the lamps from blinking, you should pay attention to higher quality models. They should have a turn-off delay of at least 2 seconds, then the lights will not blink, even if the switch has a built-in night light.
- It is advisable to screw one ordinary light bulb into a chandelier with several shades.
Precautions when using lamps
Lamps rated for medium wattage typically contain about 1 mg of mercury. This is about the same as one ball at the end of an ampoule of pen paste. Thermometers contain about 500 mg. Despite the fact that the difference in mercury content in a lamp and a thermometer is quite large, when using lamps, do not forget to be careful. Even a small amount of vapor should not enter the air. However, it is not always possible to avoid such situations.
Broken energy saving light bulb
Many buyers ask the question: “If an energy-saving light bulb breaks, what should I do?” If it does break, you need to take the following measures:
- All unauthorized persons must leave the premises, avoiding the area with the broken lamp.
- The room must be well ventilated.
- Ventilation must be done only through windows; the artificial air conditioning system must be turned off.
- If its fragments and remains must be collected using thick paper and placed in a hermetically sealed jar or plastic bag.
- Collect small parts and powder using tape or adhesive tape.
- The area where the fragments were should be treated with wet wipes. All materials that were used to collect residues must also be placed in
- If an energy-saving light bulb breaks, never collect the remaining mercury using a vacuum cleaner.
- All things that came into contact with the fragments must be thrown away. Those that are simply saturated with steam should be washed well.
- Shoes should be immediately wiped with napkins and left to air in the open air.
- All unnecessary items should be disposed of, and necessary items should be thoroughly ventilated.
- After disposing of all waste, wash your hands well.
