use in a wide range of LED lighting applica- tions including ambient lighting and linear fixtures. The new Samsung H-Series features 145lm/W luminous efficacy, which is the in- dustry’s highest in the LED module product category. The new LED module’s 5000K CCT (Correlated Colour Temperature) provides an approximately 40 percent improvement over a typical T5 fluorescent lamp and 50 percent improvement of a T8 fluorescent lamp.
DIRECTIONAL LED MODULES Osram Sylvania announced the new series of DLM1100 Directional Light Modules and DL1100 Directional Light Engines. Available in 2700K, 3000K, 3500K, 4000K and 5000K colour temperatures, DLM1100 Direction- al Light Modules and DL1100 Directional Light Engines are ideal solutions for fixture designers and manufacturers focused on directional, recessed, area and accent light- ing. These new lighting solutions provide fixture manufacturers lower costs, improved efficacy from 58 to 82 LPW and 78 to 103
LPW, respectively, and improved colour and intensity consistency while using 37 percent less energy. The DL1100 Directional Light Engine shown in figure 7, consists of 40 high-brightness LEDs on a metal core board (MCB). This stand-alone light engine can be designed into a variety of housings in combination with optical components and can be used in a wide spectrum of applications including downlighting, wallwashing, track lighting, area lighting and accent lighting. The high lumen LED package generates up to 2000 lumens of light from a compact source and comes pre-wired with connectors to simplify the mounting process.
HIGH LUMEN CHIP ON BOARD MODULE Cree extended the XLamp® CXA family of LED arrays with the new higher light output CXA2540 and CXA3050 LEDs. Optimised to simplify designs and lower system cost, the new CXA LEDs deliver 5,000 to over 10,000 lumens, enabling new applications such as high output track lights and downlights, outdoor area lighting and high bay lighting. The new CXA3050 LED, shown in figure 8, is now the brightest member of the CXA family and can enable LED replacements for up to 100 watt ceramic metal halide in spot lighting or up to 175 watt pulse-start metal halide in high-bay and outdoor area lighting. The addition of the CXA3050 LED Array also enables lighting manufacturers to rapidly expand their product portfolio with higher lumen products.

HIGH PEFORMANCE MR16 RETROFIT LAMPS Soraa announced its new perfect spectrum SORAA VIVID 2 and PREMIUM 2 LED MR16 lamp lines—the first ultra-efficient replace- ments for 65 watt and 75 watt halogen lamps, available in both 12V and mains AC voltages. A technological breakthrough made possible by Soraa’s world-record per- formance gallium-nitride on gallium-nitride
(GaN on GaN) LEDs, the new SORAA LED MR16 lamps deliver the industry’s highest light output, while rendering vivid colours, richer reds and whiter whites. The SORAA VIVID 2 and PREMIUM 2 lamps’ GaN on GaN LED technology leverages the 1000x lower crystal defect density advan- tage of the native GaN substrate, thus emit- ting substantially more light and allowing reliable operation at much higher tempera- tures. This enables a very simple and robust MR16 lamp design that uses a single LED light source and a simple heatsink, while producing 65W to 75W halogen equivalent light output and operating reliably at lamp temperatures of up to 120°C, a requirement for use in the most constrained fixtures. The SORAA VIVID 2 LED MR16 lamp has a CRI of 95 and R9 of 95 and is available in a complete suite of beam angles, colour temperatures and lumen outputs.
CONCLUSIONS LFI is definitely one of the global calendar events where new technologies and prod- ucts are launched. However, this year the quality and diversity of products on offer shows the US market has caught up with European design finesse and is catching up with Asian costing to enable what I think will be a sustainable North American light- ing market once artificial Asian subsidies have long disappeared. My opinion is the European Commission and politicians should learn from colleagues in the West if they wish to keep a strong European Lighting sector so vital to CO2 targets.
