Abstract

A circuit includes a dimming controller, an adjustable resistor connected downstream of and in series connection with the dimming controller, a driver connected downstream and in series with the adjustable resistor, and a light connected downstream and in series with the driver. Related methods are also provided. A light emitting diode (LED) light fixture has a wide adjustment range of wattage and lumen outputs. A variable output LED light fixture has adjustable lumen output. An adjustable LED light fixture is adaptable to multiple lighting environments and needs, including outdoor and indoor applications. A LED light fixture includes a LED driver with a device adjusting the maximum wattage and lumen output of LED array(s). The adjustment is not permanent and can be adjusted multiple times to tune the wattage and lumen output or as required due to changes at the installation environment.
