Most LEDs on local market have substandard qualityVan Nam By Van Nam - The Saigon Times Daily HCMC – Around 90% of the LEDs available on Vietnam’s market are of poor quality, with large volumes of them assembled by small establishments and having a very short life and low efficiency, according to the HCMC Energy Conservation Center (ECC). Director of ECC Huynh Kim Tuoc said at a meeting on energy efficiency last week that HCMC currently had around 100 LED producers and suppliers. However, around 60 of them buy components to assemble LEDs at home and their quality is poor, he noted. Tuoc said high-quality LEDs can consume 50% less electricity than normal lights like incandescent bulbs. Buyers of LEDs should query about the origins of LED chips, reflector and other parts. If the origins are unclear, their quality cannot be ensured. Tien Giang Energy Conservation Center has recently installed LEDs for some road and bridge projects. Though the supplier guarantees the life of … [Read more...] about Most LEDs on local market have substandard quality
Cape Town, home to Table Mountain, African penguins, sunshine and sea, is a world-renowned tourist destination. But it could also become famous for being the first major city in the world to run out of water.Most recent projections suggest its water could run out as early as March. The crisis has been caused by three years of very low rainfall, coupled with increasing consumption by a growing population.The local government is racing to address the situation, with desalination plants to make sea water drinkable, groundwater collection projects, and water recycling programmes.Meanwhile Cape Town's four million residents are being urged to conserve water and use no more than 87 litres (19 gallons) a day. Car washing and filling up swimming pools has been banned. And the visiting Indian cricket team were told to limit their post-match showers to two minutes.Such water-related problems are not confined to Cape Town, of course.Nearly 850 million people globally lack access to safe drinking … [Read more...] about Will Cape Town be the first city to run out of water?
LED lamps not yet popular in VietnamLe Anh By Le Anh - The Saigon Times Daily HCMC – Light-emitting diode (LED) lamps have an edge over conventional sources of lighting, but this technology has not become popular in Vietnam because of its prohibitively high cost, heard a workshop in HCMC. The workshop was held last Friday by the HCMC Sub-Directorate for Standards, Metrology and Quality in collaboration with Rang Dong Light Source and Vacuum Flask Company. According to the HCMC Energy Conservation Center, LED lamps have high luminescence efficiency, currently two times higher than fluorescent lamps. Each LED bulb can be used for 100,000 hours, 8-10 times longer than the lifespan of fluorescent lamps. In addition, LED lamps are environmentally friendly. Professor Phan Hong Khoi, director of the high-efficiency public lighting project, said the current cost of a LED lamp is far higher than other sources of lighting. What is more, Vietnam does not have any policy to encourage … [Read more...] about LED lamps not yet popular in Vietnam
