Hong Kong disappear appoint sampling ten LED light bulb on the top five black list

Hongkong Consumer Council commissioned an independent laboratory test market ten LED light bulbs, found life expectancy, light effects. It pointed out that one of the five brands, including Panasonic, Leders, LKKM, sunshine card (Sunshine) and IKEA Home Furnishing, lamp brightness decline after 3000 hours, more than 5%, failed to meet the EMSD requirements; among the average brightness of sunshine card bulb fell nearly 30%, can be regarded as a lamp failure, with the manufacturers claimed the life of thirty thousand hours was the furthest.

After testing the ten brands of LED light bulb, the company found that the light efficiency and life span of each product. Power efficiency, the output brightness of the bulb to lumen (lumen) as a unit, the brightness of each Watt power generated (lumen / Watt) calculation, the higher the value of the more electricity. LKKM bulb up to 107 lumens / Watt, that is, the highest brightness and power, but IKEA home samples have only 53.8 lumens / Watt, the worst performance.

The lamp life, Panasonic, Leders, LKKM, IKEA and Sun brand Home Furnishing five samples in 3000 hours after the lamp, the brightness decreases more than 5%, failed to meet the Department of "LED lighting voluntary energy efficiency labelling scheme". Under the program, the LED bulb output brightness fell to 70%, equivalent to the expiration of the need to replace. The sun card performance is the worst, the ten test samples have six to 3000 hours after the ignition, the brightness fell by 70%, one of the more burned, compared with the claimed life expectancy of a difference of thirty thousand hours.

The Council said, three bulbs failed to completely through the Department safety test, of which Leders and LKKM lighting insulation protection, Softboxes easy release, increase the risk of electric shock.

Panasonic said that the actual input power of the model is 9.5 watts, marked when the mining of "four homes to five". Sun said the light bulb is based on the internal key components in the standard environment, the actual operating temperature, calculate the life of the lamp, the company's test report shows that the lamp life of thirty thousand hours. IKEA said the poor performance of the light bulb has been discontinued, and has launched a new model, emphasizing product performance in line with EU requirements. LKKM to submit the test report to the Consumer Council, in line with the energy efficiency labeling requirements of the electrical and Mechanical Services Department, suspected vendors store light bulb quality.
