CAN/CSA-C811-13 (R2018) PDF Download

The CSA-C811-13 (R2018) standard establishes the minimum performance requirements for high mast luminaires commonly used in roadway lighting. It supersedes the first edition published in 1998 and includes high pressure sodium (HPS), metal halide (MH), and light emitting diodes (LED) light sources.

The standard focuses on photometric performance requirements for high mast luminaires used in roadway applications. It specifies criteria such as average luminance, average illuminance, luminance uniformity ratio, illuminance uniformity ratio, and veiling luminance ratio as defined in ANSI/IES RP-8. The standard also considers rated lamp watts and rated lamp lumens for HID sources, as well as rated luminaires watts and rated luminaires lumens for LED sources. It also incorporates criteria for light trespass, including eye illuminance and luminous intensity, as per IES TM-11.

While the standard aims to improve the energy efficiency of luminaires used in roadway and street lighting applications, it does not provide system design requirements. Instead, it specifies unit power density (UPD) levels for measuring optical efficiency, leaving the selection of optimal fixture type, pole height, and spacing to the designers' responsibility. ANSI/IES RP-8 can be consulted for guidance on design.

This standard is considered suitable for use in conformity assessment within its scope and has been developed in compliance with the Standards Council of Canada requirements for National Standards of Canada. Financial support for the development of the standard was provided by BC Hydro, the Canadian Electricity Association, Efficiency Nova Scotia, Manitoba Hydro, Natural Resources Canada, the Ontario Ministry of Energy, and Saskpower.
