    In olden times, with resistance dimmers (see Dimmer, Resistance), if the dimmer was not loaded to within 75% of its capacity, the load would not dim completely out (to black/to zero). Thus extra lights or heater coils were added to the circuit, often backstage/offstage in a corner, to make up the additional capacity.

    Even today with a modern dimmer, phase control , a ghost load of 50-100W may be required to allow full dimming of a very small load, such as a string of mini Christmas lights or a 15W practical lamp or dimmable LED replacement lamps.

    Do not confuse with ghost light.
