ljuslista

Ljuslista is a Swedish term that translates roughly to a “light list” or “lighting list.” In practical use, it refers to a document or inventory that enumerates light sources and their related specifications for a project, device, or space. The term is commonly employed in manufacturing, architecture, lighting design, stage production, and building services to provide a clear, itemized overview of all lighting components involved.

A typical ljuslista includes key details for each light source. Common fields are item identifier, fixture type, quantity, location or mounting position, and mounting height. Technical specifications often covered are color temperature (in kelvin), luminous flux (lumens), wattage, voltage or current, dimming capability, control channel or address, color rendering index (CRI), beam angle, and any special notes. The list may also indicate integration with power supplies, drivers, or control systems, as well as installation status and maintenance notes.

Usage varies by context. In manufacturing or product documentation, a ljuslista helps engineers track LEDs and lighting components across assemblies. In theatrical or architectural lighting, it serves as a planning and reference document for designers, electricians, and technicians, linking fixtures to plots, control cues, and schedules. In building management or smart-home environments, it supports configuration and maintenance of lighting networks.

Maintaining an accurate ljuslista improves reliability, safety, and energy management by ensuring all lighting elements are accounted for and correctly specified throughout a project’s life cycle.
