Abstract
A field adjustable output control usable with a luminaire to adjust dimming employs a first resistance source, and at least a second resistance source, and a shunt voltage regulator having a reference node coupled between the first and the second resistance sources to form a voltage divider that provides a reference voltage to the shunt voltage regulator, wherein the shunt voltage regulator is electrically coupled between an LED driver dimming line and a ground via first and second nodes of the shunt voltage regulator to regulate a flow of current from the LED driver dimming line based on the reference voltage supplied via the voltage divider. The second resistance source can take the form of a plurality of discrete resistors, each having a respective value of resistance, or alternatively can take the form of a potentiometer having a continuously variable value of resistance associated therewith.
