Sets out recommendations for the lighting of offices and related work areas, and locations within other workplaces where screen-based tasks are performed. It is intended to be read in conjunction with the general recommendations of AS 1680.1.

This Standard sets out recommendations for the lighting of office and similar tasks, including screen-based tasks. While the tasks may be commonly performed in interiors called 'offices', they may also be performed in other interiors; for example, reading, writing and screen-based tasks frequently occur in most types of interior workplace.This Standard should be read in conjunction with the general recommendations of AS 1680.1 and with any applicable specific recommendations in the AS 1680.2 series.NOTES:1 Separate Standards covering the lighting of specific tasks and interiors will be progressively issued to form the AS 1680.2 series (see Preface).2 See Appendix E for advice on ergonomic and other factors relating to the lighting and use of screen-based equipment (SBE).This Standard, in general, contains material that adds to or amends the recommendations in AS 1680.1. The use of this Standard without reference to AS 1680.1 is a misapplication of the Standard.
