They are probably serial so the resistance would be distributed between the 6 loads and thus the heat produced would be similarly dispersed. Hence even 150 W of power would be split between 6 25 W power draws.
Actually they should be connected in parallel. Because tungsten resistance increases with temperature, if one bulb starts out with a slightly higher resistance, it will get hotter faster and you will end up with inconsistent lighting or damaging that one bulb (if not designed for operating at 120V). Also if one bulb drops out / blows it will take out all 6. Either way the power (150W) would be the same.
