2013-05-08 09:31:48

Under normal operating conditions,the fluorescent ballast of the 20W and 40W are the same current, the lamp voltage compare is 1:2, the ballast reactance 20W 40W small. If the 20W magnetic ballast can drive 40W fluorescent lamp, difficulty in starting, start successful, the lamp voltage is lower than the rated value, low light, things will not burn. But the lamp is in this state work will filament temperature, affecting the the filament electron cloud generated long time, both ends of the tube to accelerate the black, lamp life shortened.
