Cornell University – Hughes Hall
Project Description
Property History
Cornell University Law School’s Hughes Hall was designed by famed New York architectural firm Eggers & Higgins and constructed in 1963 to house residential and dining facilities. The building underwent a recent renovation in which it was awarded a LEED® Gold Rating by the US Green Building Council. Unused space was repurposed into new, beautiful, and efficient housing for Law students.
Project Scope
Grand Light was selected to restore multiple types of historic wall sconces as part of Cornell’s renovation of Hughes Hall. In addition to the restoration, we fabricated a number of replication fixtures to replace damaged/missing ones. The fixtures restored as part of this project were original early-20th-century productions by renowned lighting designer E.F. Caldwell.
Each fixture was disassembled and carefully hand-cleaned or media blasted in an effort to conserve the original satin black finish when possible. Many of the fixtures required a reapplication of their satin black finish and received a protective museum grade wax coat. The original glass diffusers were ultrasonically and hand cleaned so they could be retained in the fixtures. We used our Industrial Caliber CNC Waterjet Cutter to accurately replicate damaged and missing mechanical components and frosted-seedy glass diffusers. The electrical components of each fixture were fully replaced and rewired with UL listed components, and converted to LED. Using traditional base sockets, we implemented screw-in LED lamps for improved illumination quality and efficiency.
Services Performed
Lighting Design & Engineering
Our process begins with reviewing existing documentation including sketches, architectural drawings, historical photographs, and an on-site inspection to gather the full scope of the project requirements. From there, Grand Light will develop a detailed proposal. As required Grand Light conducts research to assure the historical accuracy of all historic projects.
The creation of Custom Drawings, Modeling, Simulation, and Rendering is an important part of the process when it comes to the production of custom lighting. Whether it be a replication or modification of an existing lighting fixture, the client’s design, or a creation by Grand Light’s engineering team, our designs will serve as the blue print for our production process.
Our designs and subsequent mock-ups address the smallest of detail, allowing our clients to fully visualize the fixture before it goes into production, which reduces the possibility of error, and allows Grand Light to fulfill its commitment of delivering high quality lighting fixtures on schedule.

Glass Cleaning
Grand Light’s Crystal, Glass, & Acrylic Studio specializes in the cleaning, repair, fitting, custom fabrication, replacement and replication of crystal, glass, and acrylic components of varying types, sizes, and color.
Our extensive cleaning solutions include hand cleaning, abrasive, micro-abrasive, and ultrasonic cleaning technology. Our artisans utilize a proprietary cleaning solution before each component is rinsed and hand polished. We have extensive experience pinning and stringing crystal components on historic and custom lighting fixtures. Utilizing time proven techniques, our artisans install pinning wire, clips, and connecting rings on crystal components in a wide variety of sizes, shapes, and designs.
Our specialists will identify and research any missing crystal or glass component on a historic lighting fixture and offer up a similar or exact grade, size, tint, color, and shape to maintain a fixtures historical integrity.
Grand Light offers a wide variety of custom, high quality architectural glass and acrylic diffusers, available in an array of styles, types, and sizes. Our high quality architectural diffusers are available by custom order and offer unique, one-of-a-kind pieces or replications of an existing design.

Cleaning Systems
Grand Light specializes in commercial luminaire cleaning services, including the utilization of state-of-the-art Ultrasonic, Micro-Abrasive, and Hydrosonic Molecular Impact System (HSMI) Cleaning Technologies. Using our engineered cleaning systems, our artisans are able to eliminate decades of accumulated debris from any lighting fixture or surface.
Grand Light’s Industrial Ultrasonic Cleaning Tanks provide high-frequency sound waves transmitted through liquid to scrub clean the surface of immersed parts. The high-frequency sound waves, typically 40 kHz, agitate the liquid solution of water or solvent, and cause the cavitation of solution molecules.
Our Micro-Abrasive process utilizes fine abrasive media to generate an accurate, precise, and controllable abrasive jet to target and remove material (on the micron level). Our system is so precise it can remove ink from a business card without damaging the card’s surface.
HSMI is Grand Light’s unique, proprietary system includes powerful continuous super high steam production up to 369 degrees Fahrenheit with an integrated wet vacuum system insuring residual moisture and debris extraction. Purified dry vapor steam and integrated vacuum system guarantees spot free crystals and fixture frames.

Finish Application & Top Coatings
As a part of the restoration process, our artisans explore the intricate details of preserving the historical integrity of lighting fixtures including color matching and sheen of the original finish. Custom lighting finishes are available in custom painted colors, sheen, and textures as well as custom patina colors on bronze, copper, and brass components.
Our artisans can match any color or finish utilizing a variety of processes involving Powder Coat, Spray, Hot or Cold Patina Custom Recipes and Color Blending an existing finish.
Grand Light exercises meticulous techniques that are unparalleled in the application of Protective Top Coatings including binders, rust, and UV resistant protective metal oils, waxes, and lacquers with various customized sheens and tints.

LED Energy-Efficient Systems

Our Energy-Efficient LED Advantage Systems update the lighting element, wiring, and components to significantly increase the lighting quality of an area while minimizing total energy consumption and reducing maintenance costs. When incandescent lamps are upgraded to an LED system, the result is a room that is up to (3) times brighter, savings up to 80% in annual(recurring) energy costs, and extended operational lifespan.
Improvements can also be achieved through the implementation of photometric testing, intelligent controllers, photocells, motion detectors, and light lifts. All of these, often in combination, can significantly reduce operating costs and provide long term return on investment.
