Pointing towards the final system efficiency greater than 100 lm/W, the Deluxe Set emphasizes its unmatchable efficiency with fair cost for 75W up bulb replacement, high performance PAR, and downlight market.

Epistar continues its efforts in SSL technology advancement combined with its excellent manufacturing capability to commercialize LED lighting. While dedicating itself to ever higher lm/W number, Epistar also commits to delivering competitive lm/$ value to its customers.

About the Out-of-the-LAB record:
With its outstanding efficacy, higher CRI, and competitive lm/$, the solution of direct red platform is widely used in warm white application. Recently, EPISTAR LAB has successfully achieved the warm white efficacy of 216 lm/W at an operating current of 5 mA and CRI of 87 Ra at CCT of 2700K. Under a typical driving current of 15mA (or about 1 W operation equivalent), the luminous efficacy of 197 lm/W was achieved.

EPISTAR LAB’s new record adopts several technologies in high voltage chips, such as the novel substrate transfer process, lower MQW light absorption, fine structure for increasing the photon extraction efficiency, improvement on the current spreading uniformity, and improved MQW structure with excellent IQE and lower forward voltage. The superior performance warm white HV chipset is suitable for retrofit, professional lighting, and luminaires applications. EPISTAR will continue developing more advanced technologies to enhance product performances and work closely with our downstream customers to provide better LED lighting solutions to the market.

About Epistar:
Epistar Corporation, headquartered in the Hsinchu Science-based Industrial Park, Taiwan since September 1996, focuses on developing, manufacturing and marketing high brightness Light Emitting Diode (LED) products. Applying its own proprietary Metal Organic Vapor Phase Epitaxy (MOVPE) technology, Epistar has successfully commercialized the full spectrum range of high brightness LEDs with the characteristics of compact size, low power consumption and long operation lifetime.
