An LED module and luminaire are provided. The luminaire includes a controller and an optical system with adjustable optical elements and an LED module with an LED circuit board electrically coupled to the controller. The LED circuit board includes an array of LEDs configured in two or more concentric zones, each zone including a plurality of LEDs. Intensity of the LEDs of a first zone is controlled independently of the LEDs of a second zone. The controller controls the intensity of at least the first zone based upon a configuration of the adjustable optical elements. The LED module can be removed from the luminaire without removing other elements of the optical system by electrically uncoupling the LED circuit board from the controller and mechanically uncoupling the LED module from the luminaire.
