Efficiency "green" lamps significantly higher efficiency "bulbs Ilyich. Do compact fluorescent lamps (CFL) 25% of electricity consumed goes to the production of light, the light-emitting diode, led (light emitting diode – Light Emitting Diode) and oled (organic light emitting diodes), even more – 80%. Compact fluorescent lamps have appeared in the late 1980's. They significantly outperform the "old" lamp as in luminous efficiency, and on service life. If the average lifespan of incandescent bulbs – 1,000 hours, then the cfl this figure reaches 15,000 hours. However, there is a fluorescent lamp and its drawbacks. They did not immediately come to full brightness and are not intended for frequent on-off.

In addition, these lamps contain mercury. And if Europe There is a developed network of reception of spent fluorescent lamps, in Russia, the question remains open for recycling. led lamps have been used in general lighting is not so long ago. For a long time on the market were not are white LEDs, because so far there is no semiconductor material to directly create white light. But scientists have found the solution: a mixture of complementary colors or fluorescent transformation. led lamps more efficient than fluorescent, but their service life can reach up to 100,000 hours. LED-lamps contain no mercury, making them environmentally friendly. However, LEDs are still quite expensive and not have high capacity. But, experts say, the achievement of optimal parameters – just a matter of time. Presumably in three to five years, the cost of led lamps will be reduced significantly.
