unlikely that among us there are people who have never ever heard the expression, "the economy must be economical."This notion, almost soaked with mother's milk, and continues to operate today.And how else?Of themselves do not take care - will sit hungry and cold.But we have learned to save rationally, and even often act on the principle of "we are not rich enough to buy cheap things."Perhaps that is why many people believe that it is better to buy energy-saving lamps, than ordinary "light bulb Ilyich."And in this situation there is only one question - how to choose a really quality product, not to be left out in the cold.

What energy-saving light bulbs called
Already only one name, it is clear that the energy-saving lamps are called, allow at reduced power consumption to get enough bright light.The comparison is almost always carried out with the usual standard - the most common incandescent lamps.We will not change the tradition and give information on reducing energy use more advanced with respect to incandescent lamps.As far as reduced energy consumption in different types of lamps?
- energy saving bulb - 10%
- CFLs - 4-5 times
- LED lamps - 8-10 times
Impressive, is not it?Of course, spending a fraction of the energy, getting comfortable lighting, very nice.Especially with the ever-increasing electricity pricing.But for the accurate calculation of savings should be taken into account and other data.This information let us consider only the last two types of energy saving lamps.
Energy-saving lamps - characteristics and calculation of the economy
So what do you need to consider when selecting bulbs to get a clearer picture of future costs and benefits?Experts identify several important characteristics, particularly affecting the result of the calculation.So, we will compare three variants of bulbs: incandescent bulbs (LN) as a standard, compact fluorescent lamps (CFL) and LED lamps (SOM):
- approximate prices on the lamp with the brightness of 700 lumens (for IL - 75 W)in rubles:
- IL - 20
- CFL - 150
- SOM - 2000
- service life under favorable conditions (hours of continuous burning):
- LN - 1000
- CFL - 10,000
- SOM -100,000
- strength of the lamp, which affects the duration of the service
- IL - very fragile
- CFL - fragile
- SOM - vandal-proof design, which is difficult to break
Based on all these parameters, including power consumption,described in the previous section, the choice of energy-saving lamp price plays a sufficient, but not a decisive role.Why is that?Let's try to calculate how much money we spend on each of the types of lamps for the period of service 100 000 hours, and the payment of electricity we assume for 1 year to 2 rubles per kilowatt for 20 light bulbs in the apartment, burning for 5 hours a day:
- LN 100 bulbs of 20 rubles - 2000 rubles only for the purchase of the lamps themselves, without any damage, and burnout, plus the electricity bill will go for 5,500 rubles
- CFL: 10 bulbs of 150 rubles - 1500 rubles,electricity - 1440 rubles
- SOM: 1 Lamp - 2000 rubles, paying for electricity, will spend 720 rubles
situation emerges more clearly, right?And yet many of us at one time to put a round sum for the purchase of LED lamps for the whole apartment is not always afford, so preference is still lyuminestsentkam, the more they also have quite a decent performance economy.Also worth considering and periodic decrease in prices for technological innovations, because it is better to wait a year or two and buy a better option on the already affordable price.But then come into effect several factors - a waste of energy-saving lamps, their reaction to the on-off and power-line surges, as well as the impact of energy-saving lamps our health.Immediately it should be recognized that these factors negatively affect it in the CFL.
Recycling energy saving lamps
So, in fluorescent lamps use mercury (or a couple or a compound with other metals), because of which the disposal of these lamps must be specialized.However, according to many experts, the concentration of mercury is so small that the robbery in the room lamp of this type to remove harmful fumes quite simple ventilation.To be honest, somehow I did not really want to check for yourself faithful of this statement.Although discarded blown bulbs often without any waste in regular garbage bins and another one for it is not fined.
Effect of frequency on-off switch and power surges on the life of energy-saving lamps
But on the on-off picture is much sadder.Even the energy-saving lamps Navigator with "warm start" (because of which light flares with a certain delay, mitigating voltage spike when you turn on), the life of a pretty sharply reduced if the light bulb has to include off-more than 3 times a day.What can we say about the lamp less established firms.In the words of one of the experts, the maximum lamp life specified for the case when the light turns on and off only 1 time per day.Much the same can be said about the reaction of CFL instability mains.Well, can not stand these lamps surges and voltage fluctuations in our power, and because of them practically no one can formally prove the correctness of the operating conditions required to obtain warranty exchanges.However, many quite understand the people in this area (and this problem affects not only lighting the apartment, but also affects the other home appliances run on electricity), prefer to get rid of surges by a regulator - it is cheaper than constantly replacing appliances,too fast coming out of the system.
Impact of energy-saving lamps on the human body
As for the impact of energy-saving lamps on our health, here too, there are a couple of interesting points.As you know, in the emission spectrum ultraviolet fluorescent lamps present in too large quantities is not the best way affects the human body.There is a certain distance (15-30 cm) in which this effect becomes really significant.Therefore, from the CFL is better to stay away, which, incidentally, there is no difficulty, as the lights are bright enough, and do not necessarily hang them directly overhead.But over the LED lamps scholars argue that their light, on the contrary, a positive effect.Some researchers even try to prove that a long stay under the radiation of LEDs leads to a rejuvenation of the body.
So the factors influencing our decision in favor of one or another type of energy-saving lamps are many.It remains only to dock them together to choose the best option.
How to choose an energy-saving lamp
Still, the desire to reduce costs forces us to make choices.Despite all of its shortcomings, and compact fluorescent and LED bulbs rapidly fill our homes.Only need to think a little about how to reduce the influence of the negative moments.And then all has presented information may help.And judging by her, the most appropriate solution would be to combine both options of energy saving lamps, distributing them efficiently, with feeling, with the arrangement.
So, from the selection of lamps, to determine in advance what type of lamp is more profitable to install in different rooms.For example, in chandeliers bedrooms, living room, kitchen, where the light of not more than three times a day, very convenient to use fluorescent lamps, then leveled and their reaction to the too frequent on-off, and the impact on health.But in the hallway, bathroom, table and wall lamps is better to use light-emitting diodes.By the way, buying a CFL, pay attention to the markings - lights with a good spread of voltage (85-260 V) is much quieter tolerate instability voltage.
Given that energy-saving bulbs power is strong enough impact on the price, we can start saving even at the time of purchase.It is not necessary to put in three-pyatirozhkovuyu brightest bulb chandelier, it is sufficient to take the CFL 5-10 watts.In the same way it is calculated and the power LED lamps, hardly a night light bedroom lamp may need more bright than 3 watts.
for proper selection of bulbs, it is important to remember that the power of energy-saving lamps is carried out largely in the same way as that of the conventional incandescent lamp.After all, very few people want to buy newfangled energy saving lamps, if under it have to replace all the old caps.The standard is also the E27, suitable for most fixtures.Slightly less frequently used light bulbs smaller, with E14, they are found in smaller lamps, floor lamps or sconces like.Information on the pedestal can be found on the packaging of the lamp, if you have the data in doubt, it is better to ask again from the seller.
remains to mention one of the most important criteria for the selection of lamps - manufacturer.Buying energy-saving lamps Philips, OSRAM, GE, Navigator, you can be 99% sure that you will get the really high-quality products.By the way, all of these companies produce both types of energy-saving bulbs - compact fluorescent and light-emitting diode, so that the reliability of the manufacturer is justified in both cases.But for products of lesser-known (or even completely unknown) manufacturers should be treated with due caution and scrutinize a minimum warranty periods.If the average length of life of the CFL at 10 000 hours of firm guarantees only six months, this is a warning bell, calling for vigilance.
Now, when you get the most relevant information about energy-saving lamps, it is possible to start updating the lighting in your home.And let your life will appear in a good light!
