Light Bulb Volume Expander
... Expansion range for any given amplifier is determined by the setting of the adjustable resistors or rheostats in the circuit and the pilot-lamp selection. Lamps that might be tried are: #55, #44, #1891, #50, #40, and #47, in order of decreasing sensitivity. A Heathkit W5M (25-watt amplifier) was ...

Electrical ballast
An electrical ballast is a device intended to limit the amount of current in an electric circuit. A familiar and widely used example is the inductive ballast used in fluorescent lamps, to limit the current through the tube, which would otherwise rise to destructive levels due to the tube's negative resistance characteristic.Ballasts vary in design complexity. They can be as simple as a series resistor or inductor, capacitors, or a combination thereof or as complex as electronic ballasts used with fluorescent lamps and high-intensity discharge lamps.
