Not always.  For motion picture use, I'll often use a ballast to run 
household 150W bulbs at 165V.  I get a good 250W of power at almost exactly
3400'K (normal household bulbs are closer to 2800'K at rated voltage).  They
last about 4 hours on the average, as opposed to the 7 hours that 250W
photoflood bulbs last, but they cost about a quarter as much.  The color is
right on (and is more easily controlled too).
