The trend towards energy conservation, has captured worldwide attention, was not spared, and Russia. In part, this may explain the growing popularity of energy-saving bulbs in our country. Is the energy savings the only characteristic that distinguishes the energy-saving bulbs from traditional incandescent bulbs, and what to look for when buying energy-saving lamps? To help consumers sort out these issues, first is to say about how to construct energy-saving lamp. Energy saving lamp consists of 3 main components: base, fluorescent lamps and electronic unit. Cap is designed to connect the lamp to the network. Electronic control unit or electronic control gear (ECG) provides the ignition (start) and the further burning of the fluorescent lamp. ECG converts mains voltage to 220V voltage required to operate fluorescent lamps. Thanks to the electronic ballast energy saving lamp lights flicker-free and works without flashing characteristic of conventional fluorescent lamps. Fluorescent tube filled with mercury vapor and inert gas (argon), and its interior walls covered with phosphor. Under the influence of high voltage in the lamp is a movement of electrons. Collision of electrons with mercury atoms in the image of the invisible ultraviolet light, which passes through the phosphor, is converted into visible light. Through the mechanism of energy-saving bulbs can to reduce electricity consumption by 80% compared with incandescent bulbs with similar light flux. In addition to the reduced consumption of light energy-saving lamps produce less heat than incandescent bulbs. Slight heat allows the use of compact fluorescent lamps of high power in fragile sconces, lamps and chandeliers, in which incandescent with a high temperature heating can melted plastic part of the holder or the wire itself. The most common cause of failure of incandescent lamps - blown filament. The mechanism of energy-saving lamp to avoid this problem, so they have a longer life. The service life of energy-saving lamps ranges from 6000 to 12000 hours (as a rule, long lifetime specified by the manufacturer on the packaging of goods) and exceeds the service life of incandescent lamps in 6-15 times. Through this facilitated the use of energy saving lamps in remote places (for example, if in a room with high ceilings). Another advantage of energy-saving bulbs is because the surface area of ??the fluorescent lamp is greater than the surface area of ??a spiral filament. Because of this light is distributed softer, more evenly than incandescent bulbs. This is easily demonstrated by the following example: if you put a chandelier in an ordinary incandescent bulb, then the walls of the room will be visible from plafonds sharp shadows, while using a compact energy-saving lamp shade are not as sharp. Due to a more uniform distribution of light energy-saving bulbs reduce fatigue of the human eye. The latter characteristic, compare favorably to the traditional energy-saving lamps is the fact that energy-saving bulbs can have different color temperature, which determines the color of the lamp. Energy-saving lamps may have the following color temperatures of 2700 K - Soft white light, 4200 K - Daylight, 6400 K - Cool white light (color temperature measured in degrees Kelvin). The lower the color temperature, the closer the color to red, the higher - the closer to blue. Thus, the consumer gets the opportunity to enrich the color scheme of the room. Summarizing the comparison of energy-saving lamps with traditional incandescent lamps, can be noted that energy saving lamps have the following favorable changes: slight heat that allows the use of compact fluorescent lamps of high power in fragile sconces, lamps, chandeliers, energy savings of up to 80% when the same luminous efficiency , Long life, which exceeds the duration of use incandescent 6-15 times, softer, more even distribution of light, ability to create light of different spectral composition: a warm, day, cold. Having defined the differences between energy-saving bulbs from traditional incandescent bulbs, go to the answer to the question of what is important to pay attention when buying energy-efficient lamps. Although in recent years began to appear energy-saving lamps almost identical in size to conventional incandescent bulbs, almost all energy-saving bulbs is bigger than incandescent bulbs. Therefore we must pay attention to the lamp to fit into your chandelier or lamp. Fluorescent lamp is a U-shaped form and in a spiral, and spiral tube slightly smaller in size U-shaped tubes of the same power (their length is less). The form has no effect on the lamp, but the spiral tube in most cases are more expensive because they are more difficult to manufacture. Energy-saving lamps vary in their power (from 3 to 85 watts): the more powerful light - the brighter the light, but the more power consumed. Therefore, pay attention when buying a lamp on its power. Also, when buying one should bear in mind that there are two main types of caps: E27 (used in almost all ceiling chandeliers) and E14 (a little smaller than the E27, is used in small lamps, wall sconces). Choose a lamp with the socket that is suitable for your lamp or chandelier. When you select also worth bearing in mind the lamp life. If for some reason, setting the lamp is difficult, you should choose a lamp with maximum durability to as little as possible to perform the procedure to reinstall it. The last thing that can be advised when choosing a lamp - it had to its color temperature. Imagine what color is the most suit you in the room in which you intend to install the lamp, and proceeding from that, choose a lamp with color temperature 2700, 4200 or 6400 degrees Kelvin. Thus, when buying energy-saving lamps, pay attention to: the dimensions, shape of the lamp, the lamp power, the type of base, color temperature, lamp life. Given the above parameters, you can choose a lamp that best meet your needs.
