The delisting of incandescent lamps is the trend of the times. The reporter visited more than 10 lighting stores and found that only one is available, 25W, 40W, 60W and other wattage incandescent lamps, the price is between 1 yuan and 2 yuan. Sales staff said that the number of incandescent lamps sold is not much, and there are not many customers to buy, mainly some residential stairs are used for induction lamps, and some hatcheries in the countryside and a few farmers are still using them.
Another official of the lighting dealership said that he only sold some incandescent lamps under 40W in his store. Mr. Guan told reporters that due to the influence of national policies, incandescent lamps above 60W are not available. At present, energy-saving lamps and LED lamps are the protagonists of the lamp market, and the incandescent lamps are out of the market.
The main cause of LED lighting in the lighting market is the rapid development of LED lights. When she first introduced LED lights 3-4 years ago, there were only a few shops selling LED lamps. In the main lighting market of Yulin Yihuan West Road and industrial products market, LED lamps have become the main products of various shops.
The owner of a lighting store said that as long as the customer does not specify energy-saving lamps, they all recommend the use of LED lights. Since January of this year, the sales of LED lights in our store have exceeded the sales of energy-saving lamps, reaching 60.
It is understood that such a situation is mainly due to the rapid decline in the price of LED lamps. With the gradual maturity of LED lighting technology and the market, last year, brand-name lighting companies saw a price cut, and the market price of LED lights began to fall. Take a brand of 24w ceiling lamp as an example. The retail price of 400 yuan two years ago, currently only 200 yuan can be bought. And an LED lamp bead was 3-4 yuan a year ago, currently 1-2 yuan, even 5-6 before the hair can be bought. In the past, a lamp bead of the LED lamp broke the entire lamp and changed points. Now just replace the burnt lamp bead. A person in the lighting industry said that the LED lighting technology is mature and the maintenance cost is also reduced.
In addition, LED lights are more energy efficient than ordinary energy-saving lamps. A 18W LED lamp is equivalent to the brightness of a 40W energy-saving lamp. If it is calculated by 6 hours a day, a 40W energy-saving lamp will have 87.6 kWh a year, while an 18W LED lamp only needs 39.42 kWh, which saves 48.18 kWh than the energy-saving lamp.
