A spot module that has a selectable light output includes a substrate (14, 34, 84, 112, 142, 152). A plurality of optical sources (114A, 114B, 114C, 114D) are arranged on the substrate (14, 34, 84, 112, 142, 152). Each optical source (114A, 114B, 114C, 114D) includes at least one light emitting diode (116A, 116B, 116C, 116D, 146A, 146B, 146C, 146D, 156A, 156B), and at least one optical element (18, 38, 88) in operative communication with the at least one light emitting diode (116A, 116B, 116C, 116D, 146A, 146B, 146C, 146D, 156A, 156B) and having a pre-defined optical prescription. A zoom apparatus (20, 40, 90) supports the optical elements (18, 38, 88) of the optical sources (114A, 114B, 114C, 114D). The zoom apparatus (20, 40, 90) adjusts an axial separation between the at least one light emitting diode (116A, 116B, 116C, 116D, 146A, 146B, 146C, 146D, 156A, 156B) of each optical source (114A, 114B, 114C, 114D) and its corresponding at least one optical element (18, 38, 88). |
