Does temperature of a body affect the light intensity produced by it?

So I have a question asking if a bulb which is at 2,500 K and the sun at 6,000 have different white-light intensities...

Does Stefan's law for black bodies apply to bulbs and stars? 
If it does, then what exactly is a black body?

Yes. The radiated power increases with the fourth power of temperature, so something twice as hot is sixteen times as bright (Stefan-Boltzmann law). The peak wavelength of the emitted radiation has a reciprocal relationship with the temperature (Wien's law).
