Our Haverhill family offers the Hudson Valley twist on an industrial icon, produced in some form by numerous manufacturers. We set ours apart with numerous details, such as the metal-rimmed Fresnel lens glass diffuser which focuses the light for better task lighting. Other details include the knurled thumbscrews at the end of the slender arms securing the vertically embossed shade in place, displaying our commitment to authenticity.
