Absolutely. Only you need connect together two wires coming from each lamp holder (shunt).

Does ballast use amps?
Yes a ballast uses amperage. That is the number beside the letter A on the ballasts nameplate. Depending on the size of the lamp or lamps will govern the size of the amperage that the ballast will draw.
4 fluorescent lights won't come on and 2 other fixtures do what causes this?
A. no power to the fixture that won't turn on. B bad electrical connection. c. burned out fluorescent lamps d. bad lamp holders e. bad ballast f. etc.
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.
Can you use a 400W high pressure sodium bulb in a metal halide ballast?
No, the ballast has to be matched to the lamp. 250 watt ballast, 250 watt lamp. Also be sure to match the lamp type to the proper ballast even though the wattage is the same. HPS ballast to HPS lamp, Metal halide ballast to metal halide lamp and mercury vapour lamp to mercury vapour ballast.
How do you replace ac ballast where emergency ballast present?
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 type of a ballast do compact fluorescent lamps use?
a compact electronic ballast in the base of the lamp
Why does your fluresant light not work after you installed a ballast?
Do you have the right ballast for the type of lamps you are using? Check on the nameplate of the ballast to see it matches with the type of tubes you are using. Are the tubes snug in the lamp holders? Is the fluorescent fixture grounded using the fixture ground screw? Do you have voltage to the ballast? On most lamp start ups you can see the lamp filament glow on each end of the tube. If you don't see the filament glow on any of the tube ends, check the wires going to that lamp holder.

Can you use a 4ft 4 lamps T8 ballast to run 4 18in T8 lamps?
You need to match the specification for the T8 lamps in question with the ballast. There are some times form factor issues and other times the specific requirements for the lamp in question.
Compare the compact fluorescent lamp and the ordinary fluorescent lamp which has fewer spare parts?
"Compact fluorescent lamps" (or, more commonly CFLs) sold direct to consumers for installation in a standard screw-in socket have an integral ballast built into the base. The ballast converts and controls the line voltage from the socket to properly drive the fluorescent lamp. Ballasts are generally fairly complex circuitry. All fluorescent lamps require a ballast. However, most lamps used commercially ("ordinary fluorescent lamps") do not have the ballasts built into them; rather, the ballasts are hidden somewhere in the fixture.
Can you use a 70 watt high pressure sodium bulb in a 100 watt ballast?
No. The bulb has to match the ballast wattage exactly. And you can't interchange different lamps (like metal halide) either. The ballast is specific to that wattage and lamp type. The bulb will either burn out quickly or just not work properly at all

Can you use 250W metal halide bulb in a 1000W metal halide ballast?
No. The lamp has to match the ballast. The lamp will not ignite if the wrong ballast is used.
Can you use a 70 watt metal halide lamp in a 150 watt ballast?
Yes assuming the ballast is also for a metal halide lamp.
