A lighting audit measures how an installed lighting system actually performs, and compares the results with the Australian Standards, design documents and planning permit conditions that apply to it. It is the evidence a council, sporting body, asset owner or tribunal relies on to decide whether lighting is compliant.

What is a lighting audit?

A lighting audit is an on-site measurement of installed lighting. Calibrated instruments record illuminance (lux), luminance and uniformity across a defined grid, and the results are assessed against the criteria the installation has to meet. The outcome is a report stating whether the lighting complies, where it does not, and why.

An audit measures what has been built. A lighting design or feasibility study is different: it predicts performance with computer modelling before installation. A design can show compliance on paper while the installed system falls short because of aiming, mounting height, product substitution or maintenance. Only measurement confirms what has actually been delivered. Our guide to what a lighting consultant does explains how design, assessment and testing fit together.

Compliance audits and energy audits

“Lighting audit” is also used for energy audits, which count fittings and estimate running costs and the savings from an LED upgrade. A compliance audit measures light levels and light spill against standards. The two are linked: an energy upgrade should be tested afterwards to confirm the new lighting still meets the required levels. For upgrades under the Victorian Energy Upgrades program, see VEU lighting designs.

When is a lighting audit required?

  • Planning permit conditions. Councils often require evidence that installed lighting meets approved light levels and obtrusive light limits before a condition is signed off.
  • Handover of new or upgraded lighting. Verification at practical completion confirms the contractor has delivered what was designed and specified.
  • Sports facility funding and competition requirements. Sporting bodies and grant programs often require evidence that fields meet the lux level for the level of play.
  • Neighbour complaints and disputes. Measured light spill and glare at the affected property gives an objective answer, whichever way it falls.
  • VCAT and legal proceedings. Independent measurements underpin expert evidence where lighting is in dispute.
  • Before an upgrade. A baseline audit shows what the existing lighting delivers, so the upgrade can be scoped correctly and the result compared with the baseline.
  • Illuminated and digital signage. Luminance testing confirms that advertising screens and illuminated signs operate within permit and Department of Transport and Planning limits.
  • Safety. Car parks, pathways and outdoor work areas are measured where light levels affect safety or a complaint has been raised.

Types of lighting audit and the standards that apply

The criteria depend on what the lighting is for, and a single site can involve more than one.

  • Sports lighting: horizontal illuminance and uniformity across the playing area for the level of competition. AS/NZS 2560 series and sporting body facility guidelines.
  • Obtrusive light: vertical illuminance at neighbouring windows, luminous intensity towards observers, and glare, against the pre-curfew and curfew limits for the site’s environmental zone. AS/NZS 4282:2023.
  • Public lighting, pathways and outdoor car parks: illuminance and uniformity for the lighting category. AS/NZS 1158 series.
  • Interior and outdoor workplaces: task illuminance and uniformity. AS/NZS 1680 series.
  • Illuminated and digital signage: face luminance (cd/m²) by day and night, and light spill. Permit conditions, DTP requirements and AS/NZS 4282:2023.

How a lighting audit is carried out

  1. Document review. Permit conditions, approved drawings and calculations, curfew times and the applicable standards are confirmed before the site visit, so the audit tests the right criteria.
  2. Site set-up. Testing is done at night with the lighting at normal operating output and stabilised. The measurement grid is set out at the spacing the relevant standard specifies.
  3. Ambient readings. Where needed, readings are taken with the lighting off, to separate the installation’s contribution from background light such as street lighting.
  4. Measurement.
    • Illuminance is recorded at each grid point with a calibrated, cosine-corrected meter.
    • Obtrusive light is measured in the vertical plane at the affected windows or boundary.
    • Signage is measured with a luminance meter.
  5. Observations. Aiming, shielding, failed or dimmed luminaires, glare and site conditions are recorded and photographed.
  6. Analysis. Average, minimum and uniformity values are calculated and compared with the criteria. The analysis allows for the difference between new (initial) and maintained light levels.

What the audit report includes

  • Site details, date, time and conditions during testing
  • Instruments used and their calibration details
  • Measurement grid layout and all recorded values
  • Calculated averages, minimums and uniformity ratios
  • A clear compliant or non-compliant finding against each criterion
  • Photographs and observations
  • Recommendations where the lighting does not comply

Common problems lighting audits find

  • Light levels below requirement, from lumen depreciation, dirty optics or failed drivers
  • Poor uniformity from misaimed or failed luminaires
  • Spill and glare into neighbouring properties from aiming angles, missing shields, or lighting running past curfew
  • Installations that don’t match the approved design because products or mounting heights were substituted
  • Lighting well above requirement, which wastes energy and increases spill without improving performance

What happens if lighting fails an audit?

A failed audit identifies the cause, not just the result. Many problems are corrected by re-aiming, fitting shields or visors, adjusting dimming or curfew controls, or cleaning and replacing components. Others need design changes. Once corrections are made, a follow-up audit confirms compliance. That retest report is usually what the council or sporting body needs to close the matter.

Why a lighting audit should be independent

An audit is only useful if its findings are trusted. When the installer or product supplier tests its own work, councils, neighbours and tribunals can question the result. An independent consultant has no stake in whether the lighting passes, which is why independent reports carry weight in permit compliance, disputes and VCAT proceedings.

What affects the cost of a lighting audit?

  • The number and size of areas or fields to measure
  • Which standards apply and how many criteria are tested
  • Timing, including curfew testing and after-hours access
  • Travel to regional sites
  • The type of report, from a compliance report to expert evidence for VCAT
  • Whether follow-up testing is needed after remediation

Lighting audits in Melbourne and Victoria

Spaces At Night carries out independent lighting audits across Greater Melbourne and regional Victoria for councils, sporting clubs, developers, builders, asset owners and residents. Spaces At Night does not supply or install lighting, so findings are not tied to any product or contractor. Testing uses calibrated instruments, and reports reference the applicable Australian Standards and permit conditions. See recent lighting compliance projects.

Frequently Asked Questions

A lighting audit involves on-site measurement of lighting performance to verify compliance with design intent and applicable Australian Standards. This typically includes establishing a measurement grid, recording lux levels using calibrated instruments, assessing uniformity and distribution, and comparing results against standards such as AS/NZS 1158 and AS/NZS 2560.2. Findings are documented in a structured report suitable for council submissions and compliance verification.

Lighting audits are typically required where a planning permit condition calls for verification of installed lighting performance. This is common for sports lighting, public spaces, car parks and illuminated signage where councils require evidence that lighting levels, spill and overall performance meet approved criteria. Audits are also used post-installation to confirm compliance or to address complaints and disputes.

A lighting audit refers to the on-site measurement and assessment process, while a lighting compliance report is the documented outcome of that process. The audit generates the data – including lux levels, uniformity and observations – and the report presents those results in a structured format, referencing the relevant standards and confirming whether the installation meets the required criteria.

On-site lighting audits are typically completed within one to six hours depending on the size and complexity of the site. The compliance report is generally issued within five business days of testing, provided site conditions are suitable and all required information is available. Urgent projects can be prioritised where required for council submission deadlines.

Not for outdoor lighting, because daylight swamps the readings, so testing is done after dark. Interior audits can be done during the day if daylight is excluded. Otherwise they are also done at night.

Yes, if a permit condition, sporting body or contract requires verification. A compliant design predicts performance; it does not prove it. Aiming, mounting heights and product substitutions on site often change the result.

Yes. An independent audit can be commissioned by the affected resident, the lighting owner or the council. Measurements are taken at the affected property, and the findings stand on the data, whoever commissioned them.
