Many LED engineers are accustomed to make judgment according to their own opinions and would like to impose these views to economic strategies of their companies. For instance, if the annual selling plan of a certain LED company is to complete 800,000 USD sales in some regions, so the annual purchases should match up this volume. In fact, in most of time, we should consider issues from customers’ perspective. The first thing that consumers may take into account is the price and certainly, the cost-effective. Some far-sighted consumers may even compare the one-time investment and long-term investment and take some tradeoff between them. For example, if commonly used energy-saving lamps can be used about one year and costs only 10 yuan, while equivalent LED lights can serve for 5 years but costs 40 yuan. If electricity bills and other fees coming from repair and maintenance are not going to be considered of, it seems like LED lamps cost less than energy-saving lamps (only 8 yuan per year). However, most consumers may probably choose energy-saving lamps rather than LED lights. Why? Firstly, compared with other parts in the house, like necessary furniture and electrical appliances, lamps are less important. Sometimes, they may be sued as decorations in some places. It is afraid that people will not spend much money on this part if they have very limited budget. 2) The price dropping is another factor that they may think of. No one can promise that after 2-3 years, the price of LED lamps still maintain on the same level as today. As an emerging market, LED lamp prices will be definitely reduced in the near future.
However, situations are totally different in underground parking. Although LED lamps are not seen having a bright future in residential area, they really received a lot of confidence in underground parking applications. As a result of 24-hour lighting, underground parking lighting system consumed much more electricity than household lights. In order to reduce the payment on electricity, engineers would like to prefer more energy-saving lighting technology. Thus LED underground packing lights became a brand new but popular idea among them. It is estimated that LED underground packing lights can save more than 90% electricity compared with traditional fluorescent lamps. The average price of LED lights (normally dimmable tubes with infrared sensors) that used in underground parking is 135 yuan. Supposed the electricity charge is 0.6 yuan per kilowatt-hour, then constructors can get back the cost on lighting system in about 260 days if they choose to use LED underground packing lights.
