A lamp is provided that can have at least one interface on the lamp body for a selectable lumens and selectable correlated color temperature (CCT). In one embodiment, the lamp design includes a housing having a downlight geometry and a light engine including at least one string of light emitting diodes (LEDs), in which the light engine is position to emit light through a light emission end of the housing having the downlight geometry. The lamp also includes at least one first switch for selecting at least one lumen setting for the light emitted by the light engine; and at least one second switch for selecting at least one correlated color temperature. The first and second switch are mounted to the housing.
