Could certainly be different here because chandelier, but my full size lava lamp uses a little 25w appliance bulb, so six of them shouldn't be more than 150w total.
The real question is are they series or parallel.
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 bulbs (if not designed for operating at 120V nominal. 6 ideal bulbs in series would operate at 20V which would necessitate lower resistance and would explode at 120v). The higher temp and resistance would cause it to generate a higher than normal voltage drop/current/power, likely much more than the designed power, and the other bulbs may be much dimmer in comparison.
Also if one bulb drops out / blows it will take out all 6. Either way the power (150W) would be the same.
Wait, seriously? I figured they used a much more power hungry bulb! I've wanted to get one for a while but I'm always so concerned about energy efficiency I've held off buying one because I figured it was like 150W
