You are right (a bit).  This was sold as a 30 kV 50 uA supply.
However, my measurements tonight are:
Input 24 V  0.80 A  = 19 W
Output (measured after argons).
no load (argons only but no wires to lifter)  ?30 kV 100 uA
plus HV Meter (100 uA FSD movement)    28 kV  130 uA   =  3.6 W
plus lifter  (no dropping resistor)                  22 kV  400 uA   =  8.8
W
ie Net current is around 270 uA and net power used by lifter is around 5 W.
What would a 1500 W lifter look like?
The argon tubes drop about 500 V each with the load of the lifter.
The plain vanilla lifter (ie no attached neons) is 30 cm a side triangle and
jumps up very smartly to its tether limit at 2 feet.
