What is AS/NZS 4282?

AS/NZS 4282:2023 is the Australian Standard controlling obtrusive light – spill light, glare, sky glow and light trespass affecting neighbouring properties, roads and the night environment. Compliance is required by councils, planning authorities across Victoria and NSW for a wide range of development types.

If your planning permit includes a condition requiring an obtrusive lighting assessment or lighting impact assessment, AS 4282 is the standard your report must address.

When is an AS 4282 Assessment Required?

Planning authorities commonly require AS 4282 assessment for:

  • Sports field and floodlighting installations near residential boundaries
  • Commercial and retail façade lighting
  • Car yards, service stations and outdoor storage
  • Mixed-use and residential developments with external lighting
  • Digital billboards and illuminated signage
  • Post-installation audits where a lighting complaint has been lodged
  • Councils reviewing lighting performance on public assets
  • Residential desputes

How We Conduct the Assessment

Depending on the project stage and permit conditions, we deliver compliance either through on-site measurement, photometric modelling, or a combination of both.


On-site measurement – We attend the site after installation and measure illuminance (lux) and luminance (cd/m²) at relevant receptor points. Results are compared against the AS 4282 limits for the applicable environmental zone. This approach is used for post-installation audits, compliance disputes, and permit conditions requiring verified measured data.


Photometric modelling (AGi32) – For proposed developments or designs not yet installed, we build a photometric model using manufacturer IES files and the site geometry. This is the standard approach for planning submissions where a permit condition requires an obtrusive lighting impact assessment prior to installation.


Both methods produce a formal compliance report referenced to AS/NZS 4282:2023 and accepted by councils and planning authorities across all states.

Projects Near Sensitive Habitat

Where development sites are adjacent to bushland, wildlife corridors, wetlands or coastal areas, obtrusive lighting assessments may also need to address the National Light Pollution Guidelines for Wildlife (NLPGW, DCCEEW 2023). The NLPGW sit alongside AS 4282 as the two frameworks planning authorities increasingly require to be addressed together – AS 4282 covering amenity and human receptor impacts, the NLPGW covering ecological impacts.
We incorporate NLPGW considerations into our assessments where relevant, including spectral analysis, spill light modelling near habitat boundaries, and lighting management plan recommendations addressing timing, dimming and CCT specification.

Frequently asked questions

AS/NZS 4282:2023 is the Australian Standard controlling the obtrusive effects of outdoor lighting – spill light, glare, sky glow and light trespass affecting neighbouring properties and the night environment. It applies when a planning permit condition requires an obtrusive lighting or lighting impact assessment, and is the primary reference standard used by councils and planning authorities across all states.

That depends on your project stage. Pre-installation (where lighting is designed but not yet built) we prepare a photometric computer model using AGi32 and manufacturer IES files. Post-installation, we attend site and measure illuminance and luminance at receptor points. Some permit conditions specify which method is required; if yours doesn’t, we’ll advise the most appropriate approach when scoping your fee proposal.

Most assessments are completed within five to ten business days of receiving the necessary project information or completing the site visit. Urgency turnaround is available for planning submissions with hard deadlines – flag this when requesting your fee proposal.

AS4282 classifies sites into environmental zones E1 through E4 based on ambient light levels – from dark rural areas through to high-brightness urban centres. The applicable zone determines the permitted limits for spill light, luminous intensity and luminance. We determine the correct zone classification as part of every assessment.

Yes. Our AS4282 reports are prepared by IESANZ-accredited independent lighting consultants and are accepted by councils, planning authorities and VCAT across Victoria. Independence from lighting suppliers and installers means our assessments carry no conflicts of interest – a requirement some councils now explicitly state in permit conditions.
