Flicker-free with instant start electronic operation
注意關鍵字"instant start"
再參考Wiki 關於電子安定器(Electrical ballast) (大陸用語:鎮流器)(閩南語:變電阿) Instant start An instant start ballast starts lamps without heating the cathodes at all by using high voltage (around 600 V). It is the most energy efficient type, but gives the least number of starts from a lamp as emissive oxides are blasted from the cold cathode surfaces each time the lamp is started. This is the best type for installations where lamps are not turned on and off very often.
Instant start 絕非預熱式!! 因為"without heating the cathodes at all "
真正預熱式是 Programmed start A programmed-start ballast is a more advanced version of rapid start. This ballast applies power to the filaments first, then after a short delay to allow the cathodes to preheat, applies voltage to the lamps to strike an arc. This ballast gives the best life and most switch cycles from lamps, and so is preferred for applications with very frequent power cycling such as vision examination rooms and restrooms with a motion detector switch.
