From September 1 this year, incandescent bulbs are banned in the EU. The luminous efficiency of incandescent bulbs is only 5%, and the remaining 95% is all heat consumption. Incandescent bulbs are inevitably eliminated. Now in the lighting market, energy-saving and efficient LED (light-emitting diode) lamps are undoubtedly an excellent choice.

Among the many lighting products, the LED lamp has the highest score for a long time. It is environmentally friendly and energy-saving, has a long service life, and has high luminous efficiency when the lamp is first turned on. Compared with previous old-fashioned light bulbs, it can save up to 90% of electricity. Although the price may be slightly higher at present, the life of LED lamps is 25 times longer than that of incandescent lamps. In Germany, LED lamps and energy-saving lamps are the two most cost-effective lighting tools.

After successfully occupying a place in the mobile phone, automobile and television industries, the LED industry currently plans to enter the lighting market. Compared with other lamps, LED lamps are more efficient and the price will be lowered. The average annual reduction is about 30%. According to McKinsey’s survey and analysis, LED lights with a price of 20 Euros will be available for less than 3 Euros in 2020.

Due to the price drop, experts predict that this high-tech bulb will be mass-produced next year. Because Japan has experienced nuclear disasters, energy saving has become a national movement, and the use of LEDs has become very common.

At present, the biggest choice is still a dazzling array of compact fluorescent lamps, commonly known as energy-saving lamps. Energy-saving lamps consume only a little more energy than LED lamps, but after the switch is turned on, there is often a delay in turning on the lamp, and its brightness is not as good as incandescent bulbs or LED lamps. The biggest weakness of energy-saving lamps is that they contain mercury. Experts suggest that if you break the energy-saving lamp in a room, ventilate the room for 30 minutes and leave the room, then collect the debris with a damp cloth or tape, and treat it as special garbage. Experts also suggest that if the room is carpeted, after cleaning up the debris with a vacuum cleaner, you should also throw away the garbage bag.

Since 2009, the European Union has banned low-efficiency incandescent light bulbs. First, the sale of 100-watt incandescent bulbs is banned, and then 60-watt and 40-watt bulbs are banned. In the future, 25-watt incandescent bulbs will also be eliminated. The EU ban aims to save 1% of electricity consumption within the EU.

Coal-fired power plants will release a large amount of mercury vapor during the power generation process, which is the world's main source of mercury vapor emissions. Therefore, incandescent lamps are eliminated, electricity use is reduced, and environmental pollution is also reduced.
