How long is the LED life? In the period of price discount, is the life of LED products also discounted? Some insiders boldly said: One person has a lamp for a lifetime, but in this era of fast consumption, do we really need such a long-lived product? In the process of opening up the market for LED, should we reconsider whether the product positioning of LED is suitable for consumer goods such as LED products, such as one lamp for one person's life? On the one hand, from the perspective of consumers, assuming that a lamp can really have a life span of 100 thousand hours, it will take 10 years. Now the living standard of consumers is continuously improving, so that they will not change lamps for several years, will they do this? Does this almost incredible long life meet the market demand? Or this kind of long life can only become a burden to consumers, and then it will not be replaced by the embarrassing situation of waste? On the other hand, from the perspective of manufacturers, if LED products are really so long, how should manufacturers survive? No matter how big the market is, there is always a margin. From the government market to the public market to the overseas market and then to the civilian market, if the market cycle is too slow, oversupply is only a matter of time, now the reason for the reshuffle of the industry is based on the instability of the industry. What is the stable situation of the industry? If everything is set in an ideal state, long life, high performance, energy saving, environmental protection, etc. are as beautiful as advertisements, then it is only a matter of time before the LED market is saturated and many manufacturers are eliminated, will the slow circulation of this long-lived commodity be a major resistance to the development of the LED industry? According to the contradiction between the price and the life span of the LED industry, many people in the industry have proposed that products with different life span can be introduced according to the consumption level of different regions, so as to reduce the cost and conform to the psychology of consumers, so that LED products can be promoted in rural areas and other areas with low consumption levels. This kind of high consumption, high price, low consumption and low price seems to be a major way to solve the problem at present. However, large cities have high consumption levels and high requirements for LED products, but they are more likely to like the new and dislike the old. Lighting products seem to become fast-selling products in many cases. High prices and longevity seem to be a waste of the market. In order to quickly occupy rural areas and other areas with low consumption levels, the low-price offensive seems to be very useful, but in these places, the substitution rate of goods is slow. If the life of LED products is reduced due to low prices, it is difficult to convince the public.
