No. A 70 Watt metal halide bulb can not be replaced with a 150 Watt halide bulb.
Yes.
It depends......perhaps 7400 to 8500 initial lumens degrading to 5400 lumens.
No, the ballast's output is not matched to operate a fluorescent bulb.
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 assuming the ballast is also for a metal halide lamp.
The light bulb needs to match the ballast in the fixture.
Yes.

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.
Some light fixture are configured for multi wattage bulbs but as a general rule of thumb only replace a bulb with the fixtures recommended bulb other wise there are serious safety issues including bulb explosion and fire.

6000lm
Yes U can just make sure they are the same size (watts) and base configuration (R59) or so.
Yes assuming the ballast is also for a metal halide lamp.
It will power two 400 watt lamps.
400 watt metal halide fixtures can be purchased at various sites on the internet. Some sites that you may want to try out include the following: Amazon and Home Depot.
