7 Many countries outside the USA utilize different voltages, such as 220/240V therefore, low voltage power supplies may be more prevalent. Clarify scope of work with regard to the design and specification of remote (and/ or low voltage) power supplies to luminaire’s, if necessary.

8 Take into account geographical lighting conditions of the project location such as daylight hours, climate and temperature issues, marine environments, etc.


1 Luminaire specifications should be clear, concise and comprehensive. The sign of a professional specification is one that communicates both general and specific requirements in an authoritative, non-ambiguous manner. Defensibility, and respect for a luminaire design specification, is more likely if its writing reveals confidence and insight. The bidder needs to be made to realize that the author completely understands the design and construction process, and fully expects a professional and forthright response. Problems in getting what is specified are less likely when this climate is created.

2 Lighting specifications are typically done in Construction Specification Institute (CSI) format which is a standardized system for specifications in the construction industry. Architectural Lighting is found within “Division 16 – Electrical” and is customarily CSI “Section 16500” which specifically refers to luminaire’s. This is typically the case for all domestic, and international specifications as well, since they often use the CSI Specification format.

3 Lighting specifications prepared by a Lighting Designer typically serve as the “primary” specification when it comes to lighting products and architectural lighting dimming/controls for a project. This is due to the high degree of performance, optical design, aesthetic quality and finish required for the areas in the scope of work of a Lighting Designer - regardless of any overall quantities or specification volumes involved. Lighting for other areas of a project which may be specified by other team members such as the Electrical Engineer, are typically covered in sufficient detail within the outline specifications of Section 16500 for Architectural Lighting.

4 Outline specifications should have the (3) main sections: Part 1 - General (eg. Related sections, Submittals, Warranties, Quality assurance, etc.)

Part 2 - Products (eg. Fabrication, Luminaire’s & components, Product performance, etc.)

Part 3 - Execution (eg. Delivery, Installation, Aiming & adjustment)
