This Standard sets out guidelines for the control of the obtrusive effects of outdoor lighting except for those applications specifically excluded below. It includes recommended limits for the relevant lighting parameters to control these effects. As the obtrusive effects of outdoor lighting are best controlled by appropriate design, the guidance given is primarily applicable to new installations; however, some advice is also provided on remedial measures that may be taken for existing installations.This Standard specifically refers to the potentially adverse effects of outdoor lighting on nearby residents (e.g. of dwellings such as houses, hotels, hospitals), users of adjacent roads (e.g. vehicle drivers, pedestrians, cyclists) and transport signalling systems (e.g. air, marine, rail), and on astronomical observations.This Standard does not apply to-(a) public lighting, as defined in Clause 1.4.10;(b) internally illuminated advertising signs;(c) the obtrusive effects of brightly lit surfaces, e.g. floodlit buildings, and externally lit advertising signs;(d) lighting systems which are installed for the purposes of colour television broadcasting;(e) lighting systems which are of a cyclic or flashing nature; and(f) environmental impacts associated with the daytime appearance of outdoor lighting systems, including their support structures.Notwithstanding Item (c) above, whilst this Standard does not cover the obtrusive effects of the bright objects themselves, it does apply to any indirect effects produced in terms of the light technical parameters of Table 2.1.NOTES:1 Some lighting installations may require, in terms of planning ordinances, the preparation of an environmental impact statement as a prerequisite for obtaining development approval.2 See the Foreword for further information on the specific exclusions outlined above.3 Appendix A sets out general principles that should be applied in the design of outdoor lighting for the control of obtrusive effects.
