Light-emitting diode (LED) lights continue to play the main role in the Hong Kong Trade Development Council's (HKTDC) Hong Kong International Lighting Fair - Spring Edition. 'Going green is definitely the direction for lighting products in the years ahead,' says Benjamin Chau, deputy executive director of the HKTDC, the fair's organiser. 'The scope of LED lighting applications has expanded from conventional outdoor landscape to general commercial and even residential usage.' To highlight the importance of LED lighting, the fair will also include a 'Symposium on LED Lighting - Sustainability and New Technologies', which gathers industry leaders and academics to share their insights and to forecast future lighting trends. This is the second edition of the fair with about 380 exhibitors from nine countries and regions at the Convention and Exhibition Centre in Wan Chai from today to Friday. The exhibit categories include decorative lighting, green lighting, LED lighting, lighting accessories, parts and components, lighting management, design and technology and technical lighting. The demand for LED lights is increasing worldwide but there is relatively limited interest in Hong Kong due to government policies, according to Jeff Lau, senior international sales manager of Aztech Systems (Hong Kong). 'Due to the government's push for energy-saving light bulbs, there isn't much focus on LED lights at the moment,' Lau says. He adds that LED lighting products have more advantages compared with energy-saving light bulbs. 'Not only are LED lights more environmentally friendly, as they don't contain mercury found in energy saving light bulbs, they also have a longer life span and are more power efficient.' While a traditional light bulb can last for a year and eight months, LED lights usually last for 11 years, according to Aztech. Kelvin Shea, manager of Zenith Lighting, another fair exhibitor, says the high price of LED lighting deters many people, though he says prices are slowly dropping as more and more companies are producing this type of product. Shea warns consumers to be careful of what they buy as some LED lighting products on the market are of an inferior quality. 'The development of LED lighting in Hong Kong is still in its infancy compared to Europe,' he says. 'The government needs to take the lead to promote it and make sure every LED lighting product on the market is of good quality and gives high performance, or else if consumers buy a low quality brand of LED lighting and are not satisfied with the performance, they might not want to try to use it again'.
