Lighting has become essential to architecture, as it reveals the form, texture, and color of a structure, thereby influencing how users experience and perceive the space. It offers both aesthetic and functional advantages. Lighting establishes mood and defines atmosphere, while also highlighting architectural features and shaping the narrative of a building. The procurement of lighting has evolved beyond merely placing an order and waiting weeks for delivery. The current procurement process entails identifying the lighting requirements for a project, assisting in the design of lighting systems, comprehending and adhering to Canadian and USA energy codes, creating specifications, selecting products, and where we truly excel, organizing the shipping of lighting to the project in a clear and comprehensible manner. This intricate process necessitates coordination among owners, developers, general contractors, lighting designers, and electrical contractors. Increasingly, owners are taking an active role in the lighting specifications and procurement process. We have tailored our approach to accommodate the evolving needs of owners and developers who wish to engage in this process, and this is where OPL Projects excels. In 2025, we introduced the OPL Projects brand, a new division of Ocean Pacific Lighting Inc, which has been refining the lighting procurement process since 1986. Acting as the sole liaison between the project owner and the manufacturer, we ensure budget compliance, quality, timely delivery, and successful project completion. We are premier suppliers of leading North American and European brands, dealing directly with these vendors, which results in savings for our clients.
