A T8 LED tube has to be used with a ballast to bring the correct voltage to the tube for it to operate correctly. Removing the ballast from the circuit will prevent the tube from operating.
Yes, a ballast is required for HPS (high-pressure sodium) lights. The ballast helps regulate the electrical current and provides the initial high voltage needed to start the lamp. Without a ballast, the HPS light would not function properly.
You don't. The output of a ballast is for one purpose only and that is to operate the lamp that is designed for that ballast. You should be careful with high output ballasts as they can draw enough milliamps to lock your muscles up if the current is shorted through you.
No, the ballast's output is not matched to operate a fluorescent bulb.
Yes, 220 volts is in the same voltage classification as 230 volts.
ballast pump
Ballast used to be stones. With the invention of the electric pump, I think most ships will actually pump water into and out of tanks to adjust their ballast now.

No. Just make sure that the ballast you use is rated for at least as many watts as the lighting you plan to operate with it.
These tubes need a ballast to operate the tubes. The current and voltage will be marked on the fixtures ballast.
By looking at the ballast numbers I would say that they can not be substituted. The number 277 in the model number of the first ballast is the voltage supply needed to operate the ballast. The number 120 in the mofel number of the second ballast is the voltage supply needed to operate this ballast. The system looks to be operating on 120 volts as this is the ballast that you want to replace. The ballast that operates on 277 volts is for a three phase four wire system of 277/480. There are multi tap ballast in the market place that are totally universal and have voltage taps for supply voltages of 120, 240, 277,347,480 and 600 volts. You just have to chose the correct voltage tap that the lighting circuit is using. The other taps have to be capped off and taped because when this type of ballast is connected the other taps have a voltage potential on them.
The cost to operate a submersible pump depends on how big the pump is and how long its average duty cycle is.
