The blue LEDs don't take much at all. I have wired those in series with the anode of the nixie tube so the current through the LEDs is the same as the current through the tube. The voltage across 3 blue LEDs is probably 6V in total, so the actual supplied high voltage is probably 131V or thereabouts. This means the tubes consume less than 5% of the total power.
