Abstract
Cube-shaped, ventilated, individual light modules housing a lamp or bulb having different predetermined characteristics are interchangeably mounted on an expandable clip surrounding an electrical socket, by sliding the module down on the clip and simultaneously establishing electrical contact between the bulb in the module and a power source and switch. The front of the module is faced with safety glass to protect the bulb and subject, and a space is provided between the module and protective safety glass which can be fitted with one or more, swing-away, wide angle adapter, diffuser, or dichroic lenses.
