«The Candela system allows LED manufacturers to conduct root cause analysis to speed process development, quickly fine tune production processes to minimise process excursions, and ultimately achieve higher yield per wafer,» said Jeff Donnelly, group vice president, Growth and Emerging Markets (GEM) Group at KLA-Tencor. «We are pleased to add Epistar to the growing list of Candela adopters.»
Cree continues to lead with even brighter LEDs
The firm’s lighting-class XLamp XP-G LED which now delivers 140 lumens per watt is currently in production.
Cree continues to extend the advantage of its innovative, industry-leading XLamp LED family with the announcement of new levels of performance for its highly efficient XLamp XP-G LEDs, now delivering up to 140 lumens per watt.
The proven XP-G LED can help lighting manufacturers reduce system cost and complexity and can make existing designs brighter and more efficient.
By leveraging the popular XP-G LED form factor, these increases in brightness and efficacy can shorten the LED fixture design cycle and improve customer time to market, with drop-in-ready performance enhancements. Cree also boasts that its XP-G LEDs have the longest projected lifetime data published.
“The XLamp XP-G is an oft-imitated yet unmatched lighting-class LED,” said Mike Watson, Cree senior director of marketing, LED Components. “Never content, Cree continues to innovate with this highly efficient platform—raising our bar yet again by providing commercially available 140 lumen per watt components. For lighting manufacturers looking to lower system cost through high performance LEDs, the answer is Cree.”
Cree’s XLamp XP-G LEDs are optimised for directional lighting, used in a variety of applications from street and area lighting to PAR replacement lamps to high-output flashlights. Cree is also the first LED supplier to publish 10,000 hours of lifetime

data, which can allow customers to project TM-21 reported lifetimes greater than 60,000 hours, or nearly seven years.
The cool white XLamp XP-G provides up to 148 lumens and 141 lumens per watt, while the outdoor white (4000K) XP-G LED delivers up to 139 lumens and 132 lumens per watt and warm white (3000K) offers up to 122 lumens and 116 lumens per watt, all at 350mA.
XLamp XP-G LEDs are available now with standard lead times.
Bridgelux LED Arrays extend leadership in retail and hospitality lighting
The firm’s ultra-high colour rendering Decor is optimised for demanding applications such as retail, hospitality, museums and high-end architectural lighting.
Bridgelux has launched its Decor line of ultra-high colour rendering index (CRI) LED arrays.
With a CRI of 97 and a 3-step MacAdams Elipse colour control option, the Decor arrays enable lighting designers to 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, these new arrays have been spectrally engineered to closely replicate the light quality of halogen and incandescent light sources. These arrays deliver R9 and R15 values of 98, to both enhance reds and represent skin tones accurately, ensuring clean and natural lighting. The Decor series expands lighting options available to the lighting designer, complimenting the standard minimum 80 and minimum 90 CRI products already available from Bridgelux.
“The new Decor arrays take us to the next level, enabling very high-end lighting design,” said Giorgio Martini, vice president at Martini. “Developed in collaboration with Martini Lighting R&D, these new arrays have allowed us to rethink lighting and luminaire design in fresh and innovative ways. We can design precision lighting effects and striking
