Fluorescent light mounting system
摘要:
An ultrahighlight fluorescent light mounting system for filming, particularly in color. A head carries the fluorescent tubes and a removable light shield while the ballast is positioned in a container remote from the head. The head is set upon and swivable about an upper post, which is rotatably connected to a lower post, which in turn is set upon and swivable about a swivel piece extending from a standard stand. The head, light shield, first post, second post, stand, and ballast can all be dissembled from one another and placed in carrying cases.
