Can 40W fluorescent lamp electronic ballast be used in a 30W fluorescent lamp
Can't, It's ok to light up if you don't think about matching the problem. 40W ballast fitting 30W lamp tube, its lamp tube life will shorten, the early appearance of filament hair black phenomenon.
Close to the number, and with the working current of 0.4 A 0.3 to drive A 30 w lamp, lamp filament flow is easy to fuse the filament to launch electronic materials on early. However, in case of no use, the best match of the lamp tube rectifier should be used.
Ballast are parameters to adjust the tubes, according to the start-up circuit, including its inductance and capacitance of the capacity to choose. 40 w fluorescent tube, pipe flow assumption, respectively is 100 v 0.4 A lamp resistance said 0.4 euro is equivalent to the output of the ballast rated current
