Princeton University – Dickinson Hall
Project Description
Property History
The original iteration of Dickinson Hall at Princeton University was commissioned in 1869 for the purpose of accommodating additional classrooms and lecture space, and named for the first president of the university. The building was burnt down in a fire in 1920, and subsequently rebuilt in 1930 under the same name. The new Dickinson Hall was constructed as a wing of McCosh Hall and connected with the University Chapel to complete the great court.
Project Scope
Grand Light was commissioned by Princeton University to restore multiple historic wall lanterns and a wall sconce. First, the fixtures were disassembled to be media blasted with walnut and ultrasonically cleaned to preserve the existing finish. Following this, a patina repair was applied to blend the finish, and a layer of protective topcoat was applied for preservation. Several missing or damaged mechanical components were replaced with replicated parts. The existing frosted glass panels needed to be replaced with new similar in kind panels. Lastly, the electrical components of the fixtures were fully replaced and rewired with UL listed products to meet modern standards. Each fixture received a new photocell, providing automatic activation and deactivation of the light based on the ambient lighting.
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 Fabrication
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.

NRTL Testing & Listing
Utilizing only UL listed products, Grand Light’s OSHA NRTL Certified Manufacturer’s Testing and Listing Laboratory strives to ensure only the highest quality of standards go into finalizing each lighting fixture; from the rewiring of luminaires, to the installation of modern lamp technology, and the custom conversion of gas powered fixtures to electric.
Grand Light’s technicians inspect and document any electrical deficiencies on every lighting fixture prior to any electrical component replacement and rewiring. We also offer comprehensive retrofit kits for upgrading existing historic luminaire to take full advantage of modern induction lamping technology. Grand Light’s practice is to perform multiple UL tests on all electrical components and systems to ensure compliance with UL Standards for luminaires.
