FIELD ADJUSTABLE OUTPUT FOR DIMMABLE LUMINAIRES

A field adjustable output control usable with a luminaire to adjust dimming includes a plurality of voltage reference integrated circuits, each of the voltage reference integrated circuits having a respective associated voltage drop thereacross; and at least one switch operable to selectively adjust a total number of the plurality of voltage reference integrated circuits electrically coupled in series with one another between an LED driver dimming line and a ground to regulate a flow of current from the LED driver dimming line to a summed voltage that is equal to a sum of voltages respective associated voltage drops across the voltage reference integrated circuits that are electrically coupled in series with one another between the LED driver dimming line and the ground by the at least one switch.
