Edison Opto has successfully introduced a complete product line of EdiPower II HM series, which includes 5W~40W for different applications. Recently, Edison Opto has extended to 40W high-power version (HM40). Using patented phosphor, HM40 improves the thermal stability and reduce the phenomenon of light decay. Furthermore, EdiPower II HM series is based on the mirror-like MCPCB which features excellent reflectivity (up to 98 percent), so that the luminous efficacy of components can be increased by 10 percent to 30 percent and the energy waste can be reduced effectively.
