As you know, incandescent only called Lighting. In fact, her place among teploizluchateley because basically it produces heat, and only as a side effect - the light. In pursuit of energy efficiency from 1 January 2011 in Russia was banned for sale "bulbs Ilyich" 100 watts or more. Since 2014 "outside the law" can be almost all incandescent lamps over 25 watts. The measures taken are aimed at phasing out the production of energy-intensive light sources. In response, manufacturers of modern lighting technology now offers more efficient and energy-saving alternative to traditional lamps.
To replace incandescent lamps come compact fluorescent lamps (CFLs), or, as they are called, or energy-saving. CFL era dates back to 1985, when the lamps were first presented at the industrial exhibition. The main advantage of CFLs - significant energy savings compared to incandescent lamps of similar light output. They consume almost 5 times less electricity. Application area of compact fluorescent lamps is not limited, they can be used almost anywhere, were previously provided by traditional incandescent bulbs.

LED bulbs are the first place on energy efficiency: no light sources that would use less power than LED lamps. Energy efficiency LEDs can reduce energy consumption by 70% in comparison with conventional lamps. In comparison, conventional incandescent lamp produces up to 10-25 lumens per 1 watt of energy consumed, halogen - 30-50 lumens per 1 watt fluorescent - 79-90 lumens and LED - 80-120 lumens at 1 watt or more. Besides, the LED lamps, there is one big advantage - extremely long service life up to 100,000 hours, which is comparable to 11 years of continuous light.
The LED lamps are essential in translating the original design decisions on the coverage at home. Unlike other light sources, they are resistant to mechanical stress, and have a compact size. LED lights are the ceiling, wall, cut-to furniture and even the floor, which makes it possible to play with the lighting in the room. LEDs can serve as a base, and an additional source of light, and they are suitable for lighting both indoors and outdoors. LED bulbs are resistant to thermal and especially effectively in cold conditions. Operating temperature range of LEDs from minus 50 to plus 60 degrees.
The absence of glass parts, filaments, mercury and other hazardous elements makes LED lights safe to operate in contrast to other light sources.
But, despite all the advantages of LEDs have a number of drawbacks. Basic - a very high price: then to save, have to first spend. LED analog standard 25-watt bulb will cost 900 rubles.
To create a cozy atmosphere in the house is better suited halogen lamps. They have the perfect color, producing a bright, natural light, so are best suited for lighting and lighting facilities.
Halogen lamps appropriate to use in lamps for reading, table lamps, wall lamps, as they are completely safe for the eyes. Thanks to standard socket halogen lamps can now be used in almost all lamps, they can be operated on, as well from the transformer.
All halogen lamps have dimming, through which light can be made brighter or vice versa, darker, depending on your mood or needs. Most LED lamps are not suitable for this.
However, in contrast to LEDs, halogen lamps are prone to heat and can contribute, for example, fading colors of the fabrics. So close to the bright colors sofa they have no place.
Compared to traditional lamps lifetime galogenok pretty high, but energy costs are still relatively high. But at the same price they have not as biting as that LED lamps: Analog 60-watt incandescent lamp in a series of halogen lamps is 110 rubles.

To avoid mistakes when selecting lighting, consider the functional tasks of the light, for which it will be used: to illuminate the work area or place of rest for decoration apartment, house or garden. Based on this, you should pay attention to the amount of light, the optimal frequency of blinking lights and its operating temperature.
Luminous flux must be considered together with the characteristics of the fitting, which is planned to apply. Together, they meet the comfort indicators highlight specific areas. The ideal level for home interior lighting is 150-300 lux.
Optimal ripple lamp is 4-5%. The use of lighting with appreciable frequency ripple is only in temporary residence - in the hallways, bathrooms, closets and elevators, as it affects the well-being of people.
On the degree of heating is best manifest themselves LED lamps, they emit almost no heat. Heating temperature of compact fluorescent lamps is 50-60 degrees, so warm they also are not particularly work. But halogen bulbs, as we have said, a lot of heat. A lighting equipment should only be used in special luminaires.
When buying lighting to avoid low-quality goods, we should pay attention to the information provided on the packaging. It is important that it was given light output, not LEDs, and very light, marked ripple lamps, power factor (power factor). Manufacturers whose products have poor performance, as a rule, prefer not to specify it on the package.
No harm will be available with a guarantee that the manufacturer provides. Generally, the term of the warranty depends on the type of product and its scope, and can reach five years. For the consumer market the major manufacturers offer a guarantee of 3 years to energy-saving lamps and up to 3-4 years to LEDs.
