LIGHTING DEVICES OR SYSTEMS THEREOF, BEING PORTABLE OR SPECIALLY ADAPTED FOR TRANSPORTATION [1,7]

|  | F21L |
Note(s) This subclass covers devices or systems designed or specially adapted to be carried, e.g. by hand, or otherwise transported from place to place, e.g. on wheeled supports, in order to provide illumination as and where required. [7] This subclass does not cover devices or systems intended for fixed installation, e.g. vehicle lighting, or for use essentially at a permanent location, which are covered by subclass Fulltext... Hierarchy... Expanded...F21S. [7] In this subclass, it is desirable to add the indexing codes of subclasses Fulltext... Hierarchy... Expanded...F21W and Fulltext... Hierarchy... Expanded...F21Y. The indexing codes should be unlinked. [7]
