Sec. 20.7  Specific requirements.

    Two general classes of electric lamps are recognized in these 
requirements, namely: Class 1, those that are self-contained and easily 
carried by hand, and class 2, those that may or may not be self-
contained and not so readily portable as the first class.
    (a) Class 1. Class 1 includes hand lamps, signal lamps, inspection 
lamps, flashlights, and animal lamps which are operated by small storage 
batteries or dry cells.

types and large battery lamps.
