If both bulbs fit into the same socket I would presume this to be fine.
No, it is not alright to replace a 180 watt DLP TV bulb with a 200 watt bulb. You should only use the OEM rated size/wattage for your TV.
Yes, a 103 volt source will light a 60 watt light bulb. The relationship of the bulb's wattage output at a lower voltage, as to the normal voltage that the bulb is rated to operate on, the light output will be lower.
You can as long as the rating of the inverter supports the 1500 watt power requirement at the operational voltage of the bulb. There may be a surge at start-up of the bulb so that has to be taken into account.
No. A 70 Watt metal halide bulb can not be replaced with a 150 Watt halide bulb.
fluorescents are about 5x as efficientso a 12W will give about as much light
No, you can not use a 150 watt high pressure sodium bulb with a 70 watt ballast.

You will have more light but at a lower cost. They produce much less heat so that wouldn't be a problem.
Yes, it will be perfectly safe.
Yes. Lower wattage would be safe for the lamp wires and components.

A 400 watt Mercury vapor light bulb produces roughly 23,000 lumens. In comparison to a 400 watt metal haloid and or high-pressure sodium, not as good. Metal haliod and high-pressure sodium produces 30,000 lumens.
no you cant if the ballast is for a 150w bulb you have to retro fit the ballast then u can
The light bulb needs to match the ballast in the fixture.
