"60 watts" means "60 joules every second". That's what a '60 watt' bulb is
designed to consume.
If you put 100 joules of energy into a light bulb, 100 joules of energy are going to
come out of it, one way or another. Either that energy will be converted into light
and heat by the bulb's filament, or else it won't get consumed at all, and it'll come
out the other side of the bulb and still be available for use in some other device.
So, comparing output energy to input energy is not an effective way to evaluate
the efficiency of a light bulb.
What you need to do, in order to compare the economy and effectiveness of light bulbs,
is to compare LIGHT output to input ENERGY.
No. A bulb can run a AC just a easily as DC.
You have to have three factors to calculate this cost. First what you are charged per Kw/hr from your power supplier, second the wattage size of the bulb that you want to do the calculation on and third the voltage of the bulb. Give me these and I can tell you how it costs to run the bulb per hour.

That does not depend directly on the brightness of the bulb, it depends on the current drawn by the bulb (which depends on the efficiency of the bulb). For example an incandescent bulb will draw much more current than a much brighter CFL bulb or LED bulb. Therefor switching to an brighter LED bulb can make the battery last much longer while switching to a brighter incandescent bulb will make the battery run down quicker.
No, it is not recommended to run a 50 watt halide bulb on a 100 watt halide ballast. The ballast should match the wattage of the bulb to ensure proper operation and to avoid potential damage to the bulb and ballast. It is best to use a ballast that is rated for the wattage of the bulb being used.
The average lifetime of an incandescent bulb is around 2000 hours.
No
It takes a battery that delivers the voltage that the bulb is designed for, at a current of (10/bulb voltage) amperes for a reasonable length of time.
Yes, provided the bulb types are compatible with the 400 watt ballast.
You can run 3 regular 100 bulb strands on one reciptical.
No. The bulb will burn out.
