For those who are accustomed to take your money and do not want to put up with wasteful incandescent lamps, was invented by the so-called compact fluorescent (or energy saving) bulb – CFLs. As in conventional fluorescent lamps, cfl is a discharge tube filled with argon, and ballast (starter). All this construction is seated in a standard cap of diameter 27 or 14 mm (light-EP), which allows threading it into the chuck of any chandelier sconces or lamps. Lamp itself, as its name implies, looks compact and neat. Due to the fact that between the U-shaped (or spiral) and the bulb socket is an electronic starter, the height of the lamp a little more normal. But more often it does not exceed 15-16 cm If the bulb is shining an incandescent tungsten filament in a cfl light formed quite differently. Initially, the lamp appears invisible ultraviolet radiation. Inflicted the same on the inner walls of the flask special substances – phosphor-convert uv into visible light. Until recently, little fluorescent lamps used in living rooms as there were only tubular and gave Cold shadowless light. Today, thanks to the invention of compact lamps and new phosphors will have a wider choice of lamps. Energy-saving lamps with the same color intensity consume 5-6 times less electricity than incandescent bulbs. In other words, the usual 60W corresponds to the brightness of cfl power of 11 Tues Savings of electricity under such a change will be more than 80% In addition, they are much more durable. If the resource lamps incandescent, on average less than 800-1.000 hours, then their energy-saving competition it varies from 6.000 (the cheapest of the samples) to 10.000 or even 15.000 hours. Tips "seasoned" – usually on energy-saving lamps marked their color Temperature: 2.700 K – "warm white" (yellow light similar to incandescent lamps) 4.000 K – "Natural" (the tone is closer to white) 6.400 K – "Daylight" (blue and white) – Fluorescent lamps "do not like "frequent switching on and off. It is desirable that the interval between them was more than two minutes. cfl has a relatively high color rendering index of -85%. But many Chinese manufacturers, this figure does not exceed 45-55%. These lamps is better not to buy, if important to you proper display of color in the interior. – Like all fluorescent lamps, CFLs contain small amounts of mercury. Therefore, this lamp is better throw in the package. – Energy-saving lamps with electronic starter can adjust the dimmer (dimmer).
