Project Description
Property History
Bear Brook State Park is a 10,000-acre preserve located in the southeast region of New Hampshire in Allenstown and neighboring towns. It is one of New Hampshire’s largest developed state park, currently having over forty miles of trails leading to seldom visited marshes, bogs, summits and ponds, that offer a variety of options for hikers, mountain bikers and equestrians.
Project Scope
Grand Light restored numerous historic exterior wall mounted lanterns from the grounds of Bear Brook State Park. These lanterns required several mechanical repairs and fabrication of missing components, including the repair of one damaged finial, nine damaged/missing top spikes, one damaged top frame, nine damaged/missing brackets, eleven damaged/missing bottom spikes, and one missing interior reflector replaced with a similar in kind spun metal reflector finished to match existing.
The existing Verdi finishes were removed through abrasive media blasting, preparing the surfaces for the application of a new exterior architectural black finish. Sixteen missing glass diffusers were replaced with new custom-cut clear hammered type heavy granite glass diffusers. The white porcelain interior reflectors were meticulously cleaned ultrasonically and by hand, ensuring the lanterns would have optimal light distribution. All electrical components were replaced and rewired with UL-listed products and tested in accordance with UL 1598 standards.
Now back at Bear Brook State Park, these wall lanterns will preserve the historic appearance of the grounds while delivering improved lighting for the foreseeable future.

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.

Surface Preparation
Grand Light specialists perform testing on each fixture to determine the optimal surface profile for powder coat, paint, metal oil, or hot/cold patina application. Our processes utilize a wide range of equipment including Pyrolysis, Burn-Off, Thermal, and Blast Cabinets to remove an existing finish and smooth or roughen a surface.
Our industrial Pyrolysis, Burn-Off, Thermal Ovens and Heaters offer high-temperature, controlled burns for removal or vaporization of finish or foreign material from metal surfaces. Any remaining ash is removed through our blast cabinet services.
Our industrial Media Blast Cabinets are generally used to remove existing material (finish, contaminants, rust, etc.) or smooth/roughen a surface, all without causing damage to the original profile and aesthetic elements. Each cabinet houses a large work area and adjustable turn table to easily maneuver fixture frames and components.

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.
