1. A variable-effect lighting system comprising:

  • a lamp assembly comprising a plurality of multi-coloured lamps in series with an AC voltage source and in series with each other, the voltage source having a frequency, each said multi-coloured lamp comprising a first illuminating element for producing a first colour of light, and a second illuminating element for producing a second colour of light; and

    a lamp controller coupled to the lamp assembly for varying the colour produced by the lamps by varying a conduction interval of each said illuminating element according to a predetermined pattern, the controller being configured to terminate the variation upon activation of a user-operable input to the controller,wherein the lamp controller includes a non-volatile memory and is configured to retain in the non-volatile memory a daturn associated with the conduction interval of one of the illuminating elements upon the activation of the user-operable input, the lamp controller being further configured to set the conduction interval of the one illuminating element in accordance with the retained datum upon re-application of power to the lighting system.
