Lesley University Chapel
Project Description
Property History
Lesley University is a private university in Cambridge, Massachusetts, serving over 1,800 total students. The school was founded in 1909 as an all-women’s college, originally for the purpose of educating teachers. Since 2005, the school has been a co-ed institution dedicated to their core values of inquiry, diversity, community, and citizenship.
Project Scope
Grand Light restored two different types of hanging pendant lights, a total of twelve fixtures. Each luminaire was partially disassembled and cleaned to conserve their existing antique silver finishes, and had their patina repaired to blend the interior with the exterior finish. Museum grade wax top coat was applied to the fixtures to preserve them into the future. Each fixture had their electrical components replaced and rewired with a modified light cluster to accommodate LED screw-in lamps to UL standards, and the existing socket posts were modified to accommodate a new LED array. Each existing cream glass diffuser was ultrasonically cleaned.
Services Performed
On-Site Disassembly, Assembly, & Testing
Our restoration artisans are trained to safely remove and disassemble fixtures and components, labeling and photographing fixture components in sequence of its removal and as a section. Work areas are left in the same condition it was found prior to leaving the site.
For documentation our technicians inspect and note any electrical deficiencies on every lighting fixture prior to any electrical component replacement and rewiring, to ensure the fixtures can be wired in accordance with UL listed products, UL standard 1598 and hi-pot tested, with UL label (LED retrofit kits utilize manufacturers listing).
On-Site Packing, Crating, & Transportation
Grand Light frequently transports lighting fixtures using our own box trucks, flatbeds, and custom-built trailers that are designed specifically for safe transport. Our team packs all components with custom-built crates catered to each fixture in our factory. Each crate is packed and properly labeled with all necessary information per fixture type, including loose components, damages/deficiencies, and proper component placement/alignment.
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.
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.
