Philips estimates that about 90 million 75W incandescent light bulbs are sold annually in the United States. Switching to this LED replacement has the potential to reduce energy use by 5,220 megawatts of electricity, a cost savings of approximately $630,000,000 annually. According to Philips estimates, switching to the EnduraLED 21 17W could also eliminate 3,255,205 million metric tons of carbon emissions annually, or the equivalent of removing nearly one million cars from the road.


As with all bulbs in the Philips LED lighting family, the new EnduraLED A21 17W has a rated life of 25 times longer than a standard incandescent bulb. Over its lifespan, the EnduraLED A21 17W could save a business or household about $160 per bulb. Available during the fourth quarter of 2011 in the US, the manufacturer’s suggested retail price for consumers has not yet been finalised but is expected to be in the range of $40 - $45.


In addition to offering familiar soft white light, the Philips EnduraLED A21 17-watt fits into existing fixtures and works with standard dimmers, giving consumers a simple, long-lasting solution for the home. For those within the retail or hospitality sector, Philips says the bulb will provide a substantial return on investment, through extended bulb life and reduced energy and maintenance costs.


Ultratech to open HB-LED development facility in Taiwan


Scheduled to open in the second half of 2011, the Asia Technology Centre (ATC) will contain a class 1000 cleanroom that will aid developing cost-effective, scalable HB-LED manufacturing processes.


Ultratech, a supplier of lithography and laser- processing systems used to manufacture semiconductor devices and high-brightness LEDs (HB-LEDs), has opened the Asia Technology Centre (ATC) in Taiwan.


The integrated cleanroom provides the capability


for leading-edge process development and in- depth demonstrations of Ultratech’s Sapphire 100 lithography system, designed for customers in the emerging HB-LED market. To further support the company’s Singapore international operations facility, announced last year, this centre will enable cost-effective, leading-edge process development that can be transferred between sites or across Ultratech’s large customer base throughout the Pacific Rim. Scheduled to open in the second half of 2011, the ATC furthers Ultratech’s ongoing commitment to meet its international customers’ needs with advanced technology solutions at the lowest cost-of-ownership.


Ultratech Chairman and CEO Arthur W. Zafiropoulo said, “With many of our customers located in the Pacific Rim, opening our Asia Technology Centre in Taiwan enables us to work with leading companies to develop processes and lithography equipment advances to reduce the cost of manufacturing LEDs. In addition, the facility will be used to provide yield research as well as low-cost patterning solutions.”


“Ultratech remains vigilant in its search for ways to provide low-cost solutions to support the significant growth in the HB-LED markets. We look forward to leveraging our Asia Technology Centre to help speed the development of cost-effective lithography processes to support our customers’ product and technology roadmaps for new and emerging markets,” he concluded.


Building upon the cost and performance advantages of the 1500 platform, the next-generation Sapphire 100 system provides the best operational flexibility due to the fundamental benefits of the 1X lens design and market-specific technology options for high-volume, HB-LED manufacturing. The Sapphire 100 was specifically designed to meet the wide range of lithography needs and cost advantages for the HB-LED manufacturing industry.
