Abstract

Abstract This invention relates generally to ornamental lighting controls and particularly to a lighting control for Christmas tree lighting having preferably at least four duty cycle outputs and wherein the duty cycle pattern of each output differs, with respect to a predetermined time interval, from the duty cycle pattern of each of the other outputs of the control thereby to produce, in a plurality of ornamental lighting strings respectively connected to the outputs of the control, a coordinated condition of continuously changing light intensities between strings and that occur in predetermined sequential time differing order to result in an overall lighting effect totally unobtainable by any other form of light controlling apparatus.
