Our energy saving lamp is separate to the ballast and light source, avoid high temperature impact on lifespan. The life time of our energy saving lamp is 20,000hours. The designed is unique the at umbrella type light source (open based on U-shape), and research the matched lampshade, the intensity of the illumination is improve 40%. Use the technology of the fourthe active filter, make the lamp have super-high power factor (>0.99), line loss low; Super-low harmonic (total harmonic <8%), no pollution for electric net; Permanent power output, brightness steady; High reliability, life time > 20,000 hours, fault rate of 1,000 hours<3%. The 160W high power separate type energy saving lamp can replace 250W industrial lamp (save power rate 40%), and 200W can replace 400W industrial lamp (save the power rate 60%).
