Q:How to judge the quality of electronic ballast
According to the international standard, light 1 second at 20%, more than 4 seconds 80% brightness is good ballast, while 80% of that moment of brightness or four seconds can not meet the standards of the brightness of the ballast quality is poorer.
Q:You can't use a seller to say you're going to change a inductive ballast
So much trouble, you put the lamp tail apart, put down the starter (supporting the use of is the starter and ballast, electronic ballasts do not use) the starter, with a voltage above 630 v, capacity of about 4.7 to 8.2 nF polyester capacitor (the principle of inductance ballast has nothing to do with resonance phenomenon, so there is no resonance capacitance, but the capacitance is electronic ballast must)
Q:What is a ballast for use? How much is it?
When light through the high pressure after start-up, voltage drop, current increase, such as unrestricted, lamp current will continue to increase until the lamps may be burned, and so must be concatenated in the discharge lamp lighting circuit a ballast and lamp type, specification matching with the lamps start high start voltage, and limit the lamp current make the stability of a specified range.
Q:Why not use ballast from the ballast high-pressure mercury lamp?
On the other hand, it can make light and improve the color and color of the high pressure mercury lamp That's why it's called the mercury lamp
Q:Do electronic ballast need not be regenerator?
The resonance capacitance is the characteristic element of the electronic ballast, which is the same position in the circuit as the inductor of the inductor in the circuit
Q:Do those lamps need a ballast?
Happy to answer your question: In theory cannot use of electric light source directly, also is cannot use the alternating current (ac) light sources are used rectifier, because of high requirement of the voltage stability of the light source, an alternating current wave problems lead to voltage instability will greatly reduce the service life of the light source, actually it is better to remember, most energy-efficient light source need rectifier, like fluorescent lamp, LED lamp, energy saving tube and so on
Q:Does the gold halogen lamp do not need a ballast to be able to be a ballast
Can't, the role of the ballast basically has two, one is the instant when the electric fluorescent starter disconnect circuit, high voltage circuit of mercury vapor in breakdown tubes, the filament conduction; The second is that the self-inductance in the ballast is impeding the change of ac current, so that the current of the light pipe is not too big.
Q:What is the difference between electronic ballast and inductive ballast?
 electronic ballast by electronic components made from a similar constant current source circuit, when the lamp light, because the lamp lit gas before the resistance being very high, occurs when electric current flows through the high pressure, lighting it and keep constant current, and its current limiting protection tubes.
Q:How do you install 3 wire ballast
The geodesic is not connected, of course, if you have a geodesic you'd better connect it, and then the other two lines are the same as the two line ballast, Absorb the light line from the zero, The ballast line is attached to the ceiling lamp, The ballast fire line (the line controlled by the light switch).
Q:What is the difference between a energy-saving lamp and a fluorescent lamp?
The energy-saving lamps that are bought in the market. All have the variation of fluorescent lamp. Curved into garden type Do you find that if you go into a room? 100W light bulb. It's hotter. The light is general, it's a little red. Just like a room. 40W fluorescent lamp, there is no heat sensation, the light is brighter than 100W bulb. That's the reason. The energy-saving lamp doesn't feel like a fluorescent lamp. There are no 40W energy-saving lamps. There used to be 8W fluorescent bulbs and now 9W energy-saving lamps.
