First you need to determine if it's the ballast that's bad or the emergency ballast. The emergency ballast can go bad and cause the bulbs not to work or not all of them to work depending on the lights wiring setup. Push the test button on the emergency ballast which should have a red glowing indicator light. If all the lights illuminate slightly, change the emergency ballast. It's best to buy the exact ballast for this repair. i.e. If it's a T8 3 lamp fixture. Buy a T8 3 lamp ballast not a 4. You can use a 4 in place of a 3 lamp, but the 3 lamp will be more user friendly. Easiest way is to note what wires go to what. Draw a diagram if you have to and just simply match them back up.
What else can I help you with?
Can we use a fluorescent lamp in DC?
Yes, fluorescent lamps may be powered by DC but they need a DC lamp controller instead of an AC ballast and starter. The DC lamp controller is more complex. I have a 12V lantern with fluorescent lamp tubes.
How can you convert a DC generator into an ac generator?
Converting D/C into A/C is very expensive. You can use inverters to switch the direction of the current but you would probably be better off to replace your DC generator with an AC generator and if you need both AC and DC power then use a rectifier (inexpensive when compared to inverters) to convert the AC to a DC current.
What causes choke in a fluorescent tube light to burn?
There is a coil which converts ac/ to d/c in some models. Sometimes the insulation fails and the wires gets shorted. The wires are covered with a very thin layer of shellac to reduce the size of the ballast and increase inductance.
How can you generate a DC?
U sohuld replace the slip-ring which it is in the AC generator to a commutator. It is a split-ring. Then u can produce DC generator.
Where is the fuse typically located on a string of christmas lights?
The fuse is located where the AC outlet is. There are actually two fuses.
Power factor of dc ballast is 0.8. what will be the power factor same ballast in AC?
Power factor is an AC only term, and has no meaning for DC.
How a ballast resistor convert DC into ac?
A resistor, by itself, can not convert DC into AC.
Where can a HID ballast be bought?
A HID ballast can be purchased from Amazon or eBay. The term 'ballast' is used to describe large inductors used to limit AC current for fluorescent lighting.

not present

Is tube light need dc voltage?
If you mean a Fluorescent tube light then no, you don't need DC. Household Fluorescent light tubes use AC mains electricity. The mains AC is passed through a ballast coil which reduces the current. A ballast coil works best when the AC mains voltage is at least 2 times the Fluorescent tubes working voltage. So, a simple inductor ballast can be used in Europe, where the line voltage is typically 220 to 240 Volts AC, to operate a 4 foot long tube, which operates at 85 to 100 volts, depending upon design. In the US and other places that use 120 Volts AC mains, the ballast is a combination auto transformer (to raise the voltage) and an inductor (the current limiter).
Can you use metal halide bulb in Uhp ballast?
It depends if its AC or DC, you have to match the Watts and the AC/DC.. so for example a 150watt UHP AC ballast will work with a 150watt AC metal halide bulb. dont take my word on this though, this is 2nd hand information.
