All high-intensity discharge (HID) bulbs, and all fluorescent bulbs, require a ballast, which is a device that limits current. It can raise the voltage and/or heat the bulb cathodes.
Can??? Sure, you'd just need to come up with a waterproof enclosure.But the problem is, many fluorescent fixtures don't work well when the temperature drops. Yes you can use fluorescent fixtures outside, they should be approved for the purpose and make sure they have 0 degree rated ballast for cold weather starting. The new electronic type ballast work in cold weather with no problems.
This varies widely between manufacturers, whether it's a "clear" bulb or a "frosted" bulb, and what type bulb as in incandescent, florescent , quartz, etc etc
Yes. The other voltage taps will be capped of with some type in an insulation material. Choose the new voltage tap that you want to run the ballast on and connect it to the incoming "hot" wire. Insulate the old tap with an insulation material.
This depends on the type of bulb and it's efficiency. Incandescent bulbs produce 700-900 lumens at 60 watts.
If the bed lamps use a low voltage bulb then the type of transformer will be a step down transformer.
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
ballast are either electronic or iron core induction type so at the end of the day it does not matter what type it is so long as it can handle the wattage of the tube you are trying to drive any thing will work so long as you have every thing in place that the new ballast needs,electronic types need nothing to work ballast types need a starter of some kind
If it fits and the controlling ballast or electronics is compatible with the bulb type. The 240 volt socket rating is just and indicator of the maximum voltage that can be applied to the socket.
If the 250 watt bulb is a HID or similar type the ballast comes complete with the fixture. The bulb socket is also part of the fixture and comes pre-wired to the socket. To connect the bulb to the fixture all that has to be done is just screw it into the fixture's socket.
The voltage present on the secondary side of the ballast (transformer) varies as to the type of fluorescent tube or bulb that is in the fixture. The voltage will always be higher that the applied line voltage that supplies the ballast.If the fluorescent bulb screws into a lamp type of fixture, then there is no way to measure the voltage at the bulb as the tube and ballast are a combined sealed unit.
Yes a T12 lamp socket will take a T8 tube. The T8 tube will not operate. The T8 ballast is an electronic ballast where as the T12 ballast is a magnetic type. If you are changing over fluorescent fixtures to the smaller T8 lamps then the ballast has to be changed and the end sockets have to be rewired. The schematic on how to do the rewire is on the electronic ballast's label.
I have seen it both ways. Usually it is the bulb which is a few bucks. The ballast will cost more and could cost $15-$30 bucks depending on type. If you have another bulb that is working, swap it with the flicker light and see if the problem goes away. If the swapped bulb works, I always put the bad bulb in the fixture where the good bulb came from. If the bad bulb now works, you could have a seating problem with the bulb. If it flickers, replace it.
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.

More information is needed to answer this. We need the ballast and bulb type. If this ballast is not made to do what you want then it should not be done. It can cause damage to the ballast and cause fire.
There are many types of ballasts in the electrical industry. To get an answe, the type of ballast must be stated.
To answer this question the voltage of the ballast must be stated and the type of lamp in the fixture.
