Abstract: A method and apparatus for a horticultural light for use in a horticultural facility that uses current sharing across any one or more LED strings within the horticultural light. A processor determines the current requirements of the one or more LED strings that are needed to produce a given intensity level. The processor then apportions the current generation capability of a DC-DC converter across all active LED strings using time division multiple access whereby each LED string conducts its apportioned current within its allocated time slot to the mutual exclusion of the remaining active LED strings in the allocated time slot. The processor employs analog (continuous) and/or digital (discontinuous) dimming techniques within each time slot to further modulate the amount of current conducted by any LED string within its allocated time slot.
