A lighting device, comprising a lighting device element and a light engine component (comprising a solid state light emitter) that is removably supported by the lighting device element. Also, lighting device elements that comprise a lens, a housing member, a mechanical engagement region, an electrical contact region and/or means for removably supporting a light engine component. Also, lighting device elements in which a retaining structure holds a light engine component, a portion of a light engine component is exposed to a lens. Also, lighting devices that comprise means for removably supporting a light engine component. Also, methods that comprise removing a light engine component from a lighting device element and removably supporting a second light engine component on the lighting device element.
