8539.41.00.00 - Arc lamps

This HTS category, 8539.41.00.00, specifically covers arc lamps. Arc lamps generate light by passing an electric current through a gas or vapor between two electrodes, creating an electric arc. These lamps are characterized by their intense light output and are often used in applications requiring high illumination levels, such as in spotlights, projectors, stadium lighting, and specialized industrial processes. The defining feature of this classification is the mechanism of light generation via an electric arc.

Unlike its sibling category, 8539.49.00, which covers "Other" ultraviolet or infrared lamps, this classification is exclusively for arc lamps. The "Other" category would encompass any lamps producing ultraviolet or infrared radiation that are not arc lamps, such as mercury vapor lamps or incandescent infrared emitters. Therefore, the critical distinction lies in the fundamental principle of light production: an electric arc versus other methods of generating UV or IR radiation.

As this is a leaf node within the HTS classification structure, there are no further subcategories. Classification under 8539.41.00.00 is determined solely by the product's function as an arc lamp. This includes complete arc lamp units as well as specific components designed for use exclusively in arc lamp systems.
