meet or exceed the 1953 NSTC colour standard without using colour filters or secondary effects. The exceptional colour performance of QLEDs translates into a fundamental 30-40% luminous efficiency advantage over the best known OLED technology.
“The unique combination of extraordinary colour, high efficiency, demonstrated stability and low-cost patterning makes QLEDs the next breakthrough in electroluminescent technology for displays and solid-state lighting applications,” said Seth Coe- Sullivan, QD Vision Chief Technology Officer.
QD Vision says it’s deep red QLEDs now offer greater efficacy at equivalent colour than the best reported phosphorescent OLEDs, and its green and blue QLEDs match the performance of fluorescent OLEDs, but with far superior colour performance. For example, red QLEDs fabricated by QD Vision consistently achieve peak external quantum efficiencies (EQEs) of more than 18% and efficacies of more than 22 lm/W and 18 Cd/A, at 1931 CIE colour coordinates of (0.68, 0.32).
Philips unveils first LED replacement for 75W incandescent
While reducing energy consumption by 80% and lasting 25 times longer, Philips says its EnduraLED A21 17W marks another important milestone in LED lighting technology for everyday use.
Royal Philips Electronics, a manufacturer of LED lighting products, will unveil the Philips EnduraLED A21 17W light bulb at the LIGHTFAIR International tradeshow during May 17-19, 2011.
Designed to replace a 75W incandescent bulb, while reducing energy consumption by 80% and lasting 25 times longer, the Philips EnduraLED A21 17W marks another important milestone in LED lighting technology for everyday use.
“We continue to test the boundaries of LED innovation with exciting products that provide energy efficiency, ambiance and extraordinary reliability,” said Ed Crawford, General Manager of Lamps for Philips Lighting North America.

“Once again we have demonstrated that consumers do not have to wait for quality alternatives to the incandescent or to sacrifice the soft white light they have become accustomed to because LED can deliver all the benefits without compromising quality.”
The EnduraLED A21 17W is the latest addition to Philips’ comprehensive portfolio of light-emitting diode (LED) bulbs that can efficiently replace incandescents. These include 25W and 40W equivalents, as well as the ENERGY STAR-qualified Philips EnduraLED 12.5W bulb, the world’s first commercially-available 60W replacement.
The EnduraLED A21 17W, which uses the company’s high-power, next-generation LUXEON LEDs, has also been developed to meet or exceed ENERGY STAR qualifications for an LED-based replacement for the 75W incandescent light bulb. Those specifications call for delivering 1100 lumens with just 17W of electricity, a colour temperature of 2700k, a colour rendering index (CRI) of 80, and a rated life of 25,000 hours. The new bulb will be submitted to ENERGY STAR in the coming months for qualification testing.
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
