Scope note:

Brass, sometimes nickel-plated, lamps with separate burners and reservoirs, which are usually cylindrical and are mounted on a vertical rod standard on which they may be raised and lowered; fitted with tall chimneys and glass conical or hemispherical shades. Originally oil lamps with Argand burners, the term was later applied to lamps resembling the form but employing different methods of illumination.
