According to Guangdong's science and technology authorities, the output value of LED lights in the province increased by 27.7 percent year-on-year to 125 billion yuan ($19.8 billion) in the first half of the year, with exports totaling more than 54 billion yuan.

"We will rely on the solid industrial chain in Guzhen to better promote our products at home and overseas," Li said at the opening of the new store, which is expected to help generate annual sales of more than 60 million yuan by the company.

"We are also planning to open a manufacturing business in Zhongshan to meet the fast growing market demand, because the township of Guzhen has developed a very comprehensive lighting chain over the past decades," Li told China Daily.

Guangdong's policy of promoting wider use of LED lights and their decreasing prices since 2011 were major factors in the boost to business, he says.

"The cost of LED products is falling rapidly and getting closer to that of traditional lighting products. The LED lighting market penetration rate has improved a lot."

The prices of many top international brands have also dropped. For example, Philips and Toshiba have been selling LED bulbs at only 49 yuan.

"The reduced price will help boost coverage of LED lights for household use," Li says. "We will promote customers' understanding of LED lighting and speed up the replacement from traditional to LED lighting products."

Originally focusing on making Christmas lights after it was founded in 1993, Kingsun started developing LED lights and street lighting in 1998.

With its 300,000 sq m plant in Dongguan, one of the largest solid-state lighting manufacturing facilities in Asia, with more than 8,000 employees, the company has since become a leading manufacturer of both outdoor and indoor LED lighting in China, with products also covering solar street light, LED tunnel lighting and LED lighting fixtures.
