Since the markets appearedenergy-saving lamps, incandescent bulbs rapidly began to give up their positions. This is due to the fact that it comes from the very name of the product - energy savings. However, the most recent scientific studies have shocked customers with the statement that energy-saving lamps are dangerous. How to choose a housekeeper, weigh all the pros and cons and come to a single right decision?
Energy-saving light bulbs: the pros and cons
First, let's talk about the merits of these products.
- Energy saving occurs due to highluminous efficacy. Incandescent bulbs significantly lag behind energy saving in this indicator, since more than 85% of the total energy expended goes to the accumulation of heat that enters the tungsten wire. In the housekeepers the same electricity is directly converted to light.
- Continuing to talk about how energy savinglight bulbs have pros and cons, we must not forget about the durability of these devices. The average time that the light bulb is able to work without interruptions is 6-15 thousand hours. The structure of such lamps does not include the filament, which eventually burns out. Therefore, the period which the housekeeper can serve is several times longer than the time of operation of incandescent lamps.
- Energy-saving lamps allow the user to choose the level of illumination.
- The best energy-saving light bulbs, even withhigh power do not overheat. Therefore, they can be used in cramped luminaires made of materials that can be deformed by heat. At the same time, incandescent bulbs can melt the cover, plastic accessories on the chandelier and even wires, which is very dangerous.
- Light is distributed evenly throughout the room.In the construction of ordinary light bulbs, light is emitted directly from a tungsten filament in only one direction. Energy-saving lamp distributes the light as evenly as possible due to the fact that all the lights. Researchers note that this effect reduces the level of fatigue in the human eye.
Energy saving lamps and their disadvantages
So, continuing to talk about what energy-saving light bulbs have pros and cons, let's now look at the shortcomings.
- The term that an energy-saving lamp can last directly depends on the selected mode. In the rooms in which the light is switched on / off all the time, energy-saving light bulbs will not work.
- The price is quite high (from 75 to 350 rubles.).
- Warm-up time. Instantly light the room with the help of this lamp is impossible, as it warms up gradually. On average, this process lasts 2 minutes.
- It is not excluded the possibility of flicker, irritating eyes.
- Энергосберегающие лампы излучают ультрафиолет.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. Excessive ultraviolet radiation leads to skin diseases. According to medical research, the optimal lamp power for people with problem skin is 21 watts or less.
- Эти лампы невозможно использовать в люстрах, где Regulation of light intensity is provided. This happens because of inappropriate design: when the voltage drops by at least 10% of the standard, energy-saving light bulbs turn off due to lack of power.
- By their chemical composition, the lamps are not dangerous indaily use. However, breaking up, they release mercury and phosphorus into the air. According to research by scientists, the vapors of these substances from one bulb can exceed the permissible rate by a factor of 20, from which pregnant women and children who are indoors at that moment can receive irreparable health problems. If, after all, the energy-saving light bulb has broken, what to do, a simple user does not always know, so there is a set of certain rules that we have given at the end of the article.
- Mandatory special disposal. Burnt lamps are strictly prohibited to be thrown away with all other waste.
Choosing an energy-saving lamp
Today the market provides a large selection of such goods as energy-saving light bulbs. How to choose this product so that the lamp suits us according to its characteristics and cost.
Earlier, when we chose an incandescent bulb, ourThe most important questions were: how complete is the tungsten filament, the plinth, and what is the power. Based on the latter, we automatically began to calculate how many kilowatts the counter will show after using one such light bulb. Significantly low electricity consumption, therefore, a relatively small fee for its consumption - these are the advantages for which buyers prefer energy-saving light bulbs, the price is higher, but they pay for themselves over time. Moreover, the life of the "housekeeper" is big.
Considering which energy saving light bulbsThere are pros and cons, we talked about such an important indicator as work time. The average operating time of a fairly compact fluorescent lamp is at least 8 thousand hours. At the same time it will take at least 8 ordinary light bulbs. In order to save own funds, you should also make a choice in favor of a more economical option.
The most popular linear fluorescent lamps, they are quite compact due to the smaller tube diameter and low mercury content.
Energy saving lamp base
The plinths have a standard size, therefore, both in incandescent and fluorescent lamps, type one is E27.
E-14 type sockets are also possible for cases where the lamps are of a non-standard size, smaller than normal.
Energy saving light bulbs: power
The power of energy-saving light bulbs varies inradius of 3-90 watts. When choosing a lamp for the home, it is necessary to remember that the level of light output of such lamps is 5 times higher than normal. You can pick up a lamp for a room using a simple mathematical operation, you need to divide the incandescent lamp power by 5 and we will understand what we need to buy energy-saving light bulbs. How to choose This product by other indicators, consider below.
Color metric
Fluorescent lamps are designed according to specialtechnologies that allow you to reproduce different levels of lighting. These colors correspond to the cold-warm range. Color temperature depends on the quantity. The higher the temperature characteristics, the more the light reproduced by the lamp will be closer to the cold tones, and the room will be filled with blue light. Conversely, a low temperature indicator will fill the room with a reddish color.
This indicator is calculated as follows:
- Below 4000 K - warm shades.
- 4000-6400 K - day lighting.
- 6500 and higher - cold shades approaching blue.
Rules for the use of energy-saving lamps so that they do not blink
Considering the energy-saving light bulbs, the pros andcons of these products, you can not bypass the question of blinking light bulbs. This is bad for the lamp itself - it burns out faster, and for a person - a frequent change of lighting badly affects the nerves and eyes of a person.
Let's look at why the off energy-saving light bulb blinks and how to deal with the possible problem of this phenomenon.
- In terms of safety, the switches must be connected to the phase, not to zero.
- When using fluorescent lamps, the switches should not be equipped with a backlight indicator.
- So that the lamps do not blink, you should pay attentionon better models. They should have a shutdown delay of at least 2 seconds, then the lights will not blink, even if the backlight is built into the switch.
- It is advisable to screw one ordinary light bulb into the chandelier for several lampshades.
Precautions when using lamps
Lamps rated for average power, usuallycontain about 1 mg of mercury. This is about as one ball at the end of the ampoule with a pen paste. The thermometer contains about 500 mg. Despite the fact that the difference in the content of mercury in the lamp and the thermometer is quite large, using lamps, you should not forget about caution. Even a small amount of vapor must not get into the air. However, it is not always possible to avoid such situations.
Broken energy saving light bulb
Many buyers ask: "If an energy-saving light bulb has broken, what should I do?" If it still broke, you must take the following measures:
- All unauthorized persons must leave the premises, avoiding a place with a broken lamp.
- It is necessary to air the room well.
- Airing to make only with the help of windows, artificial air conditioning system must be turned off.
- If an energy-saving light bulb has broken, its fragments and residues should be collected using thick paper and placed in a hermetically sealed jar or plastic bag.
- Collect small parts and powder should be with scotch tape or tape.
- The place where there were splinters should be treated with wet wipes. All materials used to collect residues must also be placed in a sealed bag.
- If an energy-saving light bulb breaks, never collect any mercury that remains with a vacuum cleaner.
- All items that have been in contact with the fragments must be discarded. Those that are just soaked in pairs should be well washed.
- Shoes should be immediately wiped with napkins and left to air out in the open.
- All unnecessary things should be disposed of, and the necessary thoroughly ventilated.
- Wash hands thoroughly after disposing of all waste.
