Subheadings
Products classified under Tariff item 8539.41.90
Carbon Arc Lamp
A traditional carbon arc lamp creates light by arcing electricity between carbon electrodes, producing an extremely bright white light. These lamps are classic arc lamps still used in specialty lighting applications such as searchlights and stage lighting. They fall under tariff item 8539.41.90 as arc lamps not elsewhere specified.
Ceramic Metal Halide Arc Lamp
A ceramic metal halide arc lamp uses a ceramic arc tube to contain the arc discharge, offering superior color consistency and longevity. These advanced arc lamps are used in architectural and retail display lighting. They are classified under tariff item 8539.41.90 as arc lamps not elsewhere specified.
Dental Operatory Xenon Arc Lamp
A dental operatory xenon arc lamp provides high-intensity, daylight-quality illumination for dental procedures. These xenon arc lamps are precision lighting devices used in medical settings. They fall under tariff item 8539.41.90 as arc lamps not elsewhere specified, unless specifically for use in measuring, checking, or testing instruments.
High-Pressure Xenon Arc Lamp
A high-pressure xenon arc lamp provides a continuous spectrum light ideal for solar simulation and microscopy. These lamps are distinguished by their short arc gap and high lumen output. They are classified under tariff item 8539.41.90 as arc lamps not elsewhere specified.
Laboratory Spectroscopy Arc Lamp
A laboratory spectroscopy arc lamp, typically xenon or deuterium, provides stable continuum and line spectra for analytical instruments. These precision arc lamps are used in spectroscopy and other laboratory analysis. They fall under tariff item 8539.41.90 as arc lamps not elsewhere specified.
Mercury Short Arc Lamp
A mercury short arc lamp generates high-intensity UV and visible light via an electrical arc discharge in mercury vapor. These lamps are commonly used in microscopy, spectroscopy, and semiconductor manufacturing. They are classified under tariff item 8539.41.90 as arc lamps not elsewhere specified.
Metal Halide Arc Lamp
A metal halide arc lamp produces high-intensity discharge light with excellent color rendering through metal halides vaporized in an arc. These lamps are used in sports stadium lighting and large projection systems. They fall under tariff item 8539.41.90 as arc lamps not elsewhere specified.
Projection Xenon Arc Lamp
A projection xenon arc lamp is a large xenon short arc lamp (1kW-7kW) used for cinema and large venue projection systems. These high-power arc lamps are essential for IMAX and theater projectors. They are classified under tariff item 8539.41.90 as arc lamps not elsewhere specified.
Solar Simulator Xenon Arc Lamp
A solar simulator xenon arc lamp is a Class A xenon arc lamp meeting ASTM E927 standards for solar spectrum simulation in photovoltaic testing. These lamps are used in research and quality control applications. They fall under tariff item 8539.41.90 as arc lamps not elsewhere specified.
UV Curing Xenon Arc Lamp
A UV curing xenon arc lamp is a short arc xenon lamp optimized for UV curing applications in printing and coating industries. These lamps provide high UV output for rapid curing processes. They are classified under tariff item 8539.41.90 as arc lamps not elsewhere specified.
Xenon Short Arc Lamp
A xenon short arc lamp produces intense, full-spectrum white light through an electrical discharge between tungsten electrodes in xenon gas. These lamps are designed for high-intensity applications such as searchlights and projection. They fall under tariff item 8539.41.90 as arc lamps not elsewhere specified.
