 DETAILS OF LIGHTING DEVICES, OF GENERAL APPLICATION
 

Note
 

This subclass covers only those details of lighting devices which are considered to be of a kind applicable to the lighting devices covered by more than one of the subclasses F 21 L, F 21 M, F 21 P, F 21 Q, F 21 S. Such details are classified in this subclass even if they are only stated to be applied to a device of a single subclass.
