Lux on TargetTM more than doubled, enabling energy-efficient replacement of 75W halogen lamps in retail and commercial applications

LED Engin, Inc., a leader in high lumen density LED products, announces the LZ9 LuxiGenTM emitter, a new family of devices that deliver 2.5 times the lumens of existing LZ4 products within the same 7mm x 7mm footprint. The LZ9 emitter more than doubles the Lux on TargetTM, making it ideal for directional lighting fixtures such as the spot, accent and downlighting used in retail and commercial applications.  LED Engin also offers a family of secondary total internal reflection (TIR) lenses in Spot, Narrow Flood and Flood beams compatible with the new LZ9-series. The LuxiGen single emitter/ single lens combination, available in color temperatures ranging from 2700K Warm White to 6500K Cool White,  provides the equivalent performance of a 75W PAR20 or PAR30 halogen source (reference: ENERGY STAR® Integral Lamp Center Beam Intensity Benchmark Tool).

In addition to the standard CRI 80 product, the LZ9-series is the first LuxiGen series to be introduced with a CRI 90 option for applications that demand the highest levels of color rendering.  CCT binning of 3 MacAdam Ellipses is also available as a standard option for uniform color emitter to emitter.

With 1350 lumens at 3000K and 1600 lumens at 6500K color temperatures, the LZ9 emitter incorporates 9 die in a compact, 3 x 3 series-parallel configuration, package and, like the rest of the LuxiGen platform, uses a patented multi-layer ceramic substrate engineered to minimize stress on the die. The substrate has low thermal resistance to lower the junction temperature of the die for consistent performance over the service life of the product. The LZ9 emitter and TIR lens combination leads the industry in terms of ‘lux efficacy’ or lux/Watt performance, a term that is more accurate than lumens/Watt to describe the usable light delivered in downlighting applications.

“The LuxiGen LZ9 emitter fills a gap in our product offering in the often-demanded 1000 lumen range for complete systems which are commonly used to replace 50W and 75W halogen sources,” says Uwe Thomas, VP of Product Management.  “With the addition of the LZ9, LED Engin continues its focus on maximizing Lux on Target and lux efficacy at all power levels, giving our customers the freedom and flexibility to design for a range of applications.”
