A portable luminaire intended for use with two or more incandescent lamps, all of which are of
the same wattage, is able to be marked at a single location to indicate either the maximum-wattage lamp
to be used or to indicate both the number of lamps and the maximum-wattage lamp. For a unit having two
or more lamps that are not all of the same wattage, the wattage of each lamp shall be individually marked
on or adjacent to each lampholder

maximum-wattage lamp
to be used指的是总共最大功率还是单个灯泡最大功率?

to indicate either the maximum-wattage lamp to be used or to indicate both the number of lamps and the maximum-wattage lamp.
显示可被使用的任一光源的最大功率，或显示光源的数量和最大功率

应该是单个的，因为前面说过针对这些灯是相同功率的
