Abstract
The disclosed receptacle for a directional light sensor is widely adjustable around an axis and is held in adjustment by a detent that can only be reached by a tool to release the detent when adjustment becomes necessary. The receptacle has hooks that are received in a circular hole in the mounting base, the hooks'"'"' retention being sustained as the receptacle is turned during adjustment. The receptacle is mounted on the base by a simple plug-in stroke.
