LED light bulbs sold in Hong Kong vary greatly in energy-saving performance, and some products are far less efficient than what the manufacturers claim, according to the Consumer Council.
The council recently commissioned an independent lab to test LED light bulbs samples of 10 brands that are usually used by households. The results showed that only two brands got the highest score, which is 5, while one product under the Sunshine brand secured only 2 points, am730 reported.
The prices of the bulbs range from HK$47 (US$6.06) to HK$178 and each of them claims to have a life between 15,000 and 50,000 hours.
Council vice chairman Philip Leung Kwong-hon said tests on a Sunshine-branded LED light bulb showed it would last less than 3,000 hours, against the manufacturer’s claim of 30,000 hours.
Currently there is no single rapid test that is universally used in the world to check the life of an LED light bulb, he said.
All that consumers can do is to make comparisons of the products as much as they can before making a purchase, Leung said.
The Customs and Excise Department has said that it will enforce the law properly if it finds any LED light bulb products not meeting the norms prescribed under the Trade Descriptions Ordinance.
