A few days ago, the reporter visited the lighting market in the urban area and found that there are many brands and types of energy-saving lamps in the market, and the price ranges from 5 to 20 yuan per piece.
The sales staff of some brand lighting stores told reporters that the normal life of energy-saving lamps should be 8,000 hours (3 to 4 years). “In general, the energy consumption of energy-saving lamps is only about 20% of that of ordinary incandescent bulbs.â€
Industry insiders told reporters that some good quality brands of energy-saving lamps can last up to 10,000 hours, the average product life expectancy is about 1000 hours, and some even burn for 20 minutes, the life is not as good as a candle. "Good energy-saving lamps, lamps use high-efficiency trichromatic phosphors, better use of water-coated powder coating process, and inferior energy-saving lamps, using halogen powder tubes, although such lamps are inexpensive, but have a short life. Low light efficiency."
How can consumers buy qualified energy-saving lamps? The sales staff of the brand energy-saving lamp stores such as Op, Sanxiong, etc., for ordinary consumers, the preferred brands are preferred when purchasing, because the overall quality of products produced by well-known brands is better. Well, performance and safety will be up to standard, and after-sales service is in place, branded energy-saving lamps have a one-year warranty period, quality problems can be replaced within one year.
Secondly, when purchasing, you must confirm that the product packaging is complete and the logo is complete. The outer packaging of a good energy-saving lamp product usually describes the life, color rendering, and correct installation position of the energy-saving lamp. After unpacking, the energy-saving lamps should also have some necessary signs, such as power supply voltage, frequency, power rating, and manufacturer's name and trademark.
Third, the energy-saving lamps with good quality are light-emitting lamps that gradually reach the highest brightness and have good light efficiency and poor quality. The brightness is basically unchanged after power-on, the brightness is low, and the light color is dark.
In addition, when consumers choose energy-saving lamps, they should pay attention to check whether the surface is smooth, whether the powder is even, whether there is blackening, if not, can not buy; can shake the energy-saving lamps up and down, good energy-saving lamps should be inside There is no sound of shattering and squeaking, and the test is repeated on the lamp holder, and the lamp cap should not loosen and fall off.

Finally, professionals reminded that energy-saving lamps have higher requirements on power supplies. If the power supply quality is not good, the instantaneous starting current is large, and frequent starting factors will shorten the lamp life.
