2. Weak power and high maintenance cost Power source is the weakest part of LED Lights and it severely restricts the development of led high bay . The design cost now takes up to 20%. With technologies developing, it might reach the most reasonable 5-10%. The price for LED lights is lowering in each quarter. We believe it will be acceptable to all soon. 3. High price of imported LED High Bay chips Most core patents in LED industry are controlled by foreign capital and the revenue is low. With the technology improved and production increasing, cost of LED chips will be reduced. Since the main cost of LED lights are chips, as long as price of chips is lower, LED High Bay will certainly dominate the market.
