Cree used a comprehensive approach to reduce the costs of various optical, thermal, and electrical subsystems without impacting performance, resulting in an LED troffer luminaire platform emitting at ~3500K CCT at a CRI of 93. These developments built on Cree's high- brightness, low-cost LED platforms to design a novel LED component architecture that will enable low-cost troffer luminaire designs with high total system efficacy.

The project achieved cost reductions to nearly all major troffer subsystems as well as assembly costs (e.g., no thermal management components were included, owing to the optimized distribution of compact low- to mid-power LEDs), and it’s estimated that a significant manufacturing cost savings will result over Cree's conventional troffers. A key accomplishment was the development of a new compact, high-efficacy, low-cost LED component geometry with a broad far-field intensity distribution and even color point vs. emission angle. Further optimization and testing for production resulted in the XQ series of LEDs, which are currently utilized in Cree's AR series troffers and are being considered for use in other platforms. The XQ lens geometry developed in the project influenced the later development of Cree's XB-E and XB-G high-voltage LEDs, which also have a broad intensity distribution at high efficacy and are finding wide implementation in Cree’s omnidirectional A-lamps.
