CSA C866-12

1 Scope 1.1 This Standard specifies energy efficiency and performance requirements for LED luminaires of the directional and non-directional type used for general illumination, including those with a significant decorative function. 1.2 This Standard does not cover LED products (a) intended for indication, e.g., traffic lights and exit signs; (b) exclusively intended for decoration, e.g., holiday lights; and (c) intended for retrofitting into existing fixtures. 1.3 In CSA standards, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; “should” is used to express a recommendation or that which is advised but not required; and “may” is used to express an option or that which is permissible within the limits of the standard. Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material. Notes to tables and figures are considered part of the table or figure and may be written as requirements. Annexes are designated normative (mandatory) or informative (nonmandatory) to define their application.
