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.
VIII SPECIFICATION APPROACHES
A GENERAL INFORMATION
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)
