"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.

Is bulb contains a rectifier to convert ac to dc?
No. A bulb can run a AC just a easily as DC.
How much does a light bulb cost to run daily?
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.
Do a 12 volt 50 watt bulb and a 230 volt 50 watt bulb draw the same current?
A 50 watt bulb designed to run on 12 volts takes 4.17 amps. A 50 watt bulb designed to run on 230 volts takes 0.217 amps.

If you have brighter bulbs will the battery last longer or will it run down quickly?
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.
How much time would a 60w light bulb to run out of light?
The average lifetime of an incandescent bulb is around 2000 hours.
Can you run a 60 watt light bulb on a 12volt thermostat if i connect them?
No
What kind of batteries dose it take to run a 10w bulb?
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.
Can i run 350w metal light bulb on 400 volts ballast?
Yes, provided the bulb types are compatible with the 400 watt ballast.
How far can you run Christmas lights on one reciptical?
