In the era of soaring prices, a group of careful and money-saving people have been made. But how to sacrifice the quality of life on an affordable basis? In addition to the fact that the elders often turn on the air conditioner and turn off the lights, is there any effective cost-saving method? We know that incandescent lamps emit light by heating filaments, while led bulbs, as a new type of light source, can use light emitting diodes to directly convert electric energy into light energy, and under the condition of generating the same brightness, less power is consumed. The power consumption of Philips all-round LED bulbs is less than 70% of that of Philips energy-saving lamps, and it is 15% of that of traditional incandescent lamps. At present, there are many high-quality LED bulb products on the market, and the all-round LED bulbs introduced by Philips this year are even more outstanding. An 8W all-round LED bulb is equivalent to the brightness of a 60W incandescent lamp and saves more than 85 electricity than an incandescent lamp. One year, Philips all-round LED bulbs saved us nearly 35 yuan in electricity bills, and saved 521 yuan in 15 years of life. Don't underestimate this number, it is only the difference between a light bulb. If you are good at holding a house, look at the number of light bulbs used at home, then it is easy to see the advantages of LED bulbs from this book.
