GILLINDER BROTHERS INC

Gillinder Brothers Inc. specializes in the manufacturing of mission-critical lighting components and vehicle electrical systems for defense applications. Their core capabilities include the precision fabrication of lens assemblies, marker light filters, and specialized lamp bulbs designed to meet stringent military performance and environmental standards. The company demonstrates deep technical expertise in optical component engineering, ruggedized housing design, and electro-optical system integration, with a focus on durability under extreme conditions. Their products are engineered for use in aviation, ground vehicle, and tactical lighting systems, ensuring compliance with military specifications for visibility, shock resistance, and thermal stability. A key differentiator is their ability to produce highly customized, low-volume components with tight tolerances, often for legacy or specialized defense platforms requiring exact replacements or upgrades. The contractor maintains a consistent relationship with the Department of Defense, supplying mission-essential lighting and electrical components across multiple branches. Their work supports ground vehicle operations, airfield safety systems, and tactical lighting infrastructure, indicating a trusted role in sustaining and modernizing defense equipment fleets. While DLA Aviation is represented in their history, the majority of engagements are with broader DoD entities, suggesting a broad-based supplier relationship rather than a niche focus. Their primary industry focus lies in lighting equipment manufacturing under NAICS 335129 and 335139, encompassing marker lights, lens assemblies, and electric lamp components, alongside motor vehicle electrical systems under NAICS 336320. This positions them as a niche manufacturer serving the defense transportation and infrastructure sectors, with an emphasis on replaceable, high-reliability electro-optical parts. Gillinder Brothers Inc. is a small, family-owned business based in Port Jervis, New York, operating under a 2L entity structure. They hold no formal government certifications but maintain a focused presence in the defense supply chain through direct manufacturing of specialized components critical to military readiness.
