Photography. Problems about the use of pig's mouth photography lamp (condenser)

Beam tube and radome are not used like you. Beam tube is used to reduce the area of light and make it stand out locally. The function of radome is to increase the directivity of light. This strong light is usually used to outline the edge of the subject, rather than illuminating the whole subject to show details.
