wooster paint brush   the lamp fell by about 20%, with better energy efficiency. (2) eliminate flicker, the light source output is more stable. Help to improve visual resolution, improve efficiency; reduce visual fatigue continuous operation, help protect vision. (3) the starting point is more reliable. After successfully starting the lamp warm-up time to avoid a number of the starting point. (4) high power factor. More in line with national standards 20W fluorescent lamp, the power factor greater than 0.95. (5) a stable input power and output luminous flux. Good regulation performance, when a large power supply, voltage deviation, can maintain a constant power source, stable light intensity conducive to energy conservation. (6) to extend lamp life. Constant power and lamp current decreases, and a reliable starting point and other factors can extend lamp life. (7) Low noise. Electronic ballasts up to 35db less noise, people do not feel the noise. Source: wffb.cn/fhc131456-News-385731 /
