Cree Announces Industry’s Most Energy- Efficient Neutral and Warm Lighting-Class LEDs
2010-03-17
XLamp XP-G LEDs available up to 109 lumens per watt at 3000 K CCT
Cree, Inc., a market leader in LED lighting, announces the commercial availability of the award-winning XLamp® XP-G LED in warm- and neutral-white color temperatures (2600 K to 5000 K CCT). These new XP-G LEDs extend Cree’s highest level of light output and efficacy across the white color spectrum, driving general lighting applications such as LED replacement lamps, outdoor area and commercial luminaires.
The warm white (3000 K) XLamp XP-G provides up to 114 lumens and 109 lumens per watt at 350 mA. Driven at 1.0 A, the XP-G warm-white produces up to 285 lumens at 84 lumens per watt, which is four times the light output than the highest available XLamp XR-E warm-white LED at equal efficacy.
The neutral-white (4000 K) XLamp XP-G provides up to 139 lumens and 132 lumens per watt at 350 mA. Driven at 1.5 A, the XP-G neutral-white produces up to 463 lumens, which is four times the light output of the XLamp XR-E cool-white LED at equal efficacy.
“We are excited to be working with the newest Cree XP-G LEDs,” said Bob Fugerer, president, Sunovia Energy Technologies, Inc. “The extremely high efficacy levels are enabling us to offer our Aimed Optics™ luminaires in a neutral color while maintaining the same pace- setting mounting-height-to-pole-spacing ratio and fitted target efficiency that we previously achieved with cool-white color temperatures.”
“Cree is once again setting industry-leading efficacy levels in warm and neutral white,” said Paul Thieken, Cree, director of marketing, LED Components. “These new XP-G LEDs can enable LED lighting products that not only meet but exceed the current ENERGY

STAR® luminaire and lamp requirements. Cree is accelerating the LED lighting revolution by pushing through performance milestones.”
XP-G LEDs deliver high efficacy at high current, potentially reducing the required number of LEDs, as well as the size and cost of LED fixtures. Neutral-white and warm-white XP-G LEDs are commercially available now in the industry’s smallest ANSI-based chromaticity bins. To find an authorized Cree XLamp distributor in your area, please visit

Umicore completes construction of new US germanium substrates production facility
2010-03-17
Materials technology company Umicore has completed the construction of its new germanium substrates production facility in Quapaw, Oklahoma, USA, adjacent to the existing site.
The 40,000 square foot facility is now undergoing process start-up and qualification runs. The new substrate facility is located on the same campus as the Umicore germanium optics and high purity chemicals operation for the US market and will be integrated in the existing IS014001, 2004 system in the course of 2010. This allows for a completely integrated supply chain operation, emphasizing prompt internal recycling thereby minimizing inventory stocking requirements of the valuable germanium metal.
The production operation itself is modelled on the Olen facility in Belgium which has successfully supplied millions of substrates for space and terrestrial photovoltaic applications. The new facility in Quapaw embodies proven state-of-the-art equipment and an advanced product tracking system.
“With Quapaw in addition to Olen, our total installed annual production capacity stands at 1 million germanium wafers (4” eq). With our two
