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.
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
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.

The real question is are they series or parallel.
