technology that delivers higher flux, lower forward voltage and lower thermal resis- tance than other technologies, the XLamp XT-E Royal Blue LED delivers up to 525mW at 350mA and 85C. The new XT-E Royal Blue LED is also available in 2.5-nm wavelength bins to allow customers to achieve desired color consistency.


Cree announced the acquisition of Ruud Lighting at a net cost of approximately $525 million. Combining two highly complemen- tary LED innovators, the acquisition allows Cree to extend its leadership position and increase the adoption of energy-efficient LED lighting.


Demonstrating the future of lighting, Cree unveiled a concept LED lamp from its light- ing research and development team with a high-performance LED lamp delivering more than 1,300 lumens at 152lm/W using Cree TrueWhite Technology (figure 10).


25,000 hours.


SEPTEMBER 2011 XICATO: Applied the new IESNA TM-21-11 methodology with LM79 and LM80 data to its high current, high flux XSM module LM-80 data set and it yielded an L94 (94% of origi- nal light output) at 50,000hrs demonstrating the longevity of its technology as shown in figure 11.


OCTOBER 2011 BRIDGELUX: Launched the Décor LED ar- ray range with a CRI of 97 and a 3-step MacAdams Ellipse colour control option. The decor arrays enable lighting design- ers to truly render a full palette of colours over a wide range of light levels to create stunning and sophisticated lighting effects. Delivering 1200 to 2500 lumens, the new arrays have been spectrally engineered to closely replicate the light quality of halogen and incandescent light sources up to 150W and are ideal for retail applications. These arrays deliver R9 and R15 values of 98, to both enhance reds and represent skin tones accurately, ensuring clean and natural light- ing.

LIGHTING SCIENCE GROUP: Announced the Definity 60W-equivalent replacement lamp to be priced at less than $15 that will be jointly manufactured by Lighting Science Group and electronics manufacturer Dixon Technologies, first targeting the LED lighting market in India beginning year-end 2011. At a retail price below $15, the payback from electricity savings versus incandescent light bulbs is eight months and the LED bulb has an expected life of approximately eight years. PHILIPS: Philips Lighting North America has announced that it has won the US Depart- ment of Energy’s 60-watt replacement bulb category of the Bright Tomorrow Lighting Prize (L Prize) competition. Samples of the Philips 10-watt LED lamp were submitted in 2009 and have completed 18 months of field, lab and product testing. Performance requirements included an output in excess of 900lm, and a useful lifetime of more than


Xicato launched an effective, directional 3500K flux module that is not available in conventional sources. For the first time con- sistency between an ambient lighting layer of 3500K, with a 3500K accent layer can be achieved. For markets that have not histori- cally used 3500K, this new CCT is simply another tool for lighting designers. OSRAM: Announced they had set the lumi- nous intensity record with an LED spotlight. For the first time ever a laboratory had successfully generated a rating of 124,000 candelas for an LED spotlight with a cover- age angle of 7.5 degrees and 4075 lumens. Thus, combined with a very good colour rendering of 92 and a warm white 3000K co- lour temperature, LED spotlights now reach a power range that to date had been previ- ously reserved for high-intensity discharge lamps. This kind of spotlight is of particular interest for architecture and shop illumina- tion, where they create new possibilities. In order to attain these high ratings, the phos- phors, as well as the connection technology, were adjusted for optimum results. In ad- dition to innovations in the development of light generating areas, the latest generation of chip technology is also used: the UX:3. EUROPE: The European phase-out of low-ef- ficiency lamps, which began two years ago, now encompasses clear 60W incandescent lamps. From September, the 60W incandes- cent lamp can no longer be manufactured in Europe or imported into the region. The new regulation comes into force as a result of the Ecodesign Directive (2009/125/EC), which has already outlawed 100W and 75W incandescent lamps (in September 2009 and September 2010, respectively). Fortunately, one can still purchase 40W incandescent bulbs whilst LED bulb equivalents improve in quality and reduce in price!


Bridgelux also announced the introduction of the Micro SM4 that dramatically reduces the component count, cost, complexity and size of the lighting system, enabling a cost- effective, high performance LED solution for diffuse and directional lighting, such as 20- 40 watt incandescent, 20-35 watt halogen, B10-style (candelabra), and low wattage compact fluorescent lamp replacements. Using only 4.6 watts of power, the Micro SM4 will deliver between 330 and 520 lu- mens in both warm white (2700K and 3000K) and cool white (5600K) colour tempera- tures. Minimum 80 and 90 CRI options, with 3-step MacAdams Ellipse colour selections, will be offered for warm white products. Production shipments of the Micro SM4 will be available in the first quarter of 2012. XICATO: Launched two new higher flux XLM 3000lm and 4000lm modules that directly match the optical performance of Ceramic Metal Halide double-ended, and single- ended lamps. The two modules possess an efficacy of over 70 lumens per watt, full dimmable to 0.1%, with instant-on and co- lour point consistency to 1 x 2 SDCM initially and overtime. The new XLM modules pro- vide luminaires with a new light source for incorporation into accent and architectural lighting luminaires.


Xicato is one of the first LED module com- panies to publish ‘Light Quality for Life’ information that determines how the LED module deviates over elongated testing.


Figure 12: Xicato colour shift tests show deviation less than 2SDCM.
