Do you put a ceiling on a ceiling in front of the ceiling
It's a lot of power, it's a lot of power, and it's a lot of trouble with the ballast. Now there are energy-saving radio lamps, direct power sources, power saving, and not easily broken. One of the hotels we made, the whole selection of the lights, was pretty good. The key is energy efficiency and durability. If you want to choose your kind, it is better to do well in the keel, sealing the plate before sealing the plate, and finally sealing the plate only by installing the light.
Due to the ballast in fluorescent lamp work, there is always an electric current passes through, so prone to vibration, and fever, so have a ballast of fluorescent lamp, especially the ballast quality is bad, will produce very big voice, use a long time, also easy to burn out. Ballast electronic ballast and inductance ballast
To install smallpox, the lamp must be installed in front of the ceiling. On the ballast is fluorescent lamp current limiting effect and the production of instantaneous high pressure equipment, it is made in silicon steel core put enameled wire, such iron core coil, open/close the electricity in an instant, can produce high voltage, self inductance on the electrodes at the ends of the tube (filament). This movement is alternating, when the regenerator (bubble) closes, the filament of the lamp passes through the ballast. When open the starter and ballast can produce high feeling on the ends of the tube filament, filament electron bombardment wall of fluorescent powder, repeated several times to break the starter, such movement will be repeated several times, to get through tubes. When lamp normal luminescence, smaller resistance, always keep open state, the starter of the electric current is stable through work lamp, ballast, lamp to normal light.
