Emeralite-style Banker's Lamp

This is a classic banker's lamp, famously known by the brand name Emeralite. The lamp features a rectangular, cased-glass shade in a deep hunter green color layered over white glass to optimize light reflection downward while minimizing eye strain. The shade is supported by a brass-finished metal frame and a vertical fluted column. The base is circular and tiered with decorative fluting, characteristic of 20th-century office lighting. It includes a pull-chain switch mechanism. The condition shows heavy dust accumulation and significant surface tarnishing on the brass base, indicating a lack of recent maintenance but potentially preserving the underlying finish. There are visible fingerprints on the glass shade, though no immediate cracks are observed. This piece appears to be a mid-to-late 20th-century reproduction of the original Art Deco period designs. The quality is standard for commercial office furniture of that era, featuring robust metal construction and heavy glass that suggests good craftsmanship.

I have completed a visual examination of the vintage banker's lamp. The piece possesses several hallmarks of the iconic Emeralite style, most notably the cased hunter green/white glass shade designed to diffuse light for office work. However, based on the specific proportions of the fluted column and the casting style of the tiered base, I have identified this as a mid-to-late 20th-century reproduction rather than a signature H.G. McFaddin & Co. pre-1930s original. The lack of brass screw-thread shade hold-downs common in early models supports this conclusion. The condition is fair to good. While the glass shade appears structurally sound without chips, there is significant oxidation and surface tarnish on the brass-finished base. The 'as-found' state, characterized by heavy dust and fingerprints, indicates it has not been curated in a professional collection. In the current secondary market, authentic Early Period Emeralites (Models 8734 or 9) command $400 - $800, whereas high-quality mid-century reproductions like this one are consistent performers in the $125 - $175 range due to their timeless aesthetic and functional appeal. Limitation of Verifiability: This appraisal is based solely on digital images. Without a physical inspection, I cannot confirm the presence of maker's marks on the underside of the base or the interior of the shade rim. To definitively authenticate this as a period piece, I would need to inspect the wiring for era-specific insulation, check for the presence of 'EMERALITE' embossed on the shade attachment, and perform a lead-test on the glass composition. Any discovery of original manufacturer stamping would significantly increase the valuation.
