reactor ballast
Blast in tube lights actually ionized the enclosed gas in the tube so that the current start to flow in gas and light produced.
A ballast is kind of like a transformer in the fact that it changes the voltage of the power coming in. The ballast is the black box and not a part of the bulb itself.

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
yes
You have a failing bulb or ballast.
Not recommended. It would work but shorten lamp life and may cause risk of fire. However, if you just wanted to check a lamp was capable of striking it would be ok for a few minutes. I've done the opposite in the past and used a 150w lamp with a 100w ballast. Works, but not good for any of the components, including lamp.
A higher wattage HPS bulb may work with a ballast that is rated for a lower wattage bulb , but may appear to be dim and will not produce the rated light output. It is best to match ballast and bulb accordingly.

Yes, provided the bulb types are compatible with the 400 watt ballast.
Purchase a new bulb and see if it works. If it does, the ballast is good, if it does't the ballast is bad. Return the new bulb and purchase a new ballast. Or, just buy a new fixture....its cheaper.

Make sure you are using a metal halide bulb and the ballast is matched to the wattage on the bulb. These both must be correct.

No. The lamp has to match the ballast. The lamp will not ignite if the wrong ballast is used.
No, you can not use a 150 watt high pressure sodium bulb with a 70 watt ballast.

no you cant if the ballast is for a 150w bulb you have to retro fit the ballast then u can
