– Why it matters

Brightness is a genuine safety and amenity consideration

Illuminated signage sits close to roads, footpaths and homes, so its brightness has a real effect on the people around it – driver visibility at night, glare for residents, and the character of the surrounding streetscape. AS/NZS 4282, DTP and CASA set out the limits that keep signage effective without creating that impact, and a proper assessment gives council the evidence they need to approve it with confidence.

– Process

Three stages, from submission to certificate

Approval Submission

Photometric simulation demonstrating the proposed signage meets AS/NZS 4282, DTP, CASA requirements, for permit approval.

Post-Installation Testing

On-site luminance and lux testing under day, dusk, and night conditions, verifying real-world performance against the approved design.

Certification

A formal compliance certificate confirming the signage meets all standards and permit conditions.

Digital Screens

Sky Signage

Roadside Pylons

Illuminated Signage

– Applications

Assessed by signage type

DIGITAL

Digital screens

LED and digital displays – luminance varies with content, so adaptive dimming must be verified day and night.

BILLBOARD

Billboards

Large-format signage, digital or static – brightness control matters most near intersections and highways.

AVIATION

Sky signage

High-rise rooftop business identification. CASA assessment applies where the sign is visible to nearby flight paths.

FAÇADE

Retail façades

Digital or backlit, typically required to operate within curfew periods to preserve residential amenity nearby.

ROADSIDE

Roadside pylons

Freestanding digital or static pylon signage assessed for driver visibility and glare at the roadside.

MOBILE

Movable signage

Truck-mounted and trailer-mounted displays, assessed for the same brightness and glare criteria as fixed installations.

Illuminated Signage Compliance & Brightness Testing

Councils, CASA, and the Department of Transport (DTP) require illuminated signage to operate within strict limits for brightness, light spill, and hours of operation.

Our role is to provide independent computer modelling, lighting impact assessments, and compliance guidance to support planning permit approvals and ensure illuminated signage operates within the relevant brightness and obtrusive lighting requirements.

Post-installation luminance testing and verification can also be undertaken to confirm the installed signage aligns with approved conditions and operational limits.

Our reports are structured to align with town planning permit conditions and are commonly submitted as part of council approval or condition discharge requirements.

Typical applications: digital screens, billboards, pylon signage, service station signage, retail façades, and sky signage.

We assess a wide range of illuminated signage including digital billboards, freestanding pylons, sky signs, retail façades, and branding displays.

– FAQ

Frequently Asked Questions

Signage compliance ensures illuminated signs meet required standards for brightness, light spill, and operating hours as defined in AS/NZS 4282 and local council planning schemes. Compliance testing verifies that lighting levels and glare are within acceptable limits to protect surrounding properties and public amenity.

Yes. Most councils and regulatory authorities require a compliance report to be submitted before and after installation to confirm that illuminated signage meets planning permit conditions and relevant lighting standards.

Pre-approval assessments and lighting simulations are typically completed within 3-5 business days. Post-installation testing and certification are usually finalised within a week of the site visit, depending on project requirements.

Yes. All reports are prepared by a qualified lighting designer and IESANZ Member, using calibrated testing equipment and recognised lighting standards. Our compliance reports are commonly submitted to councils, CASA and transport authorities as part of planning approval processes.

-How

Typical Applications Explained

Night time operation of electronic signage is governed by AS/NZS 4282 standard. Billboards require tight brightness control to prevent driver glare, particularly near intersections and highways.
Sky signs often require CASA assessment when visible to flight paths.
Retail façades must operate within evening curfew periods (typically 11pm-6am) to preserve residential amenity.
Digital LED screens demand the most scrutiny, as luminance varies with content. Verifying adaptive dimming is essential to show signage compliance both day and night.
By tailoring our testing to each application, we provide accurate data that councils and regulators rely on.

-Who

Why Choose Independent Certification?

Choosing Spaces At Night means working with a specialist team focused solely on compliance – not product sales. Our reports are prepared by a qualified lighting designer (MIES, IESANZ) and are accepted by councils, CASA, and the Department of Transport.

We understand that time matters. Pre-approval simulations are usually delivered within 5 business days, and post-install certification is generally finalised within a week.
This combination of independence, technical depth, and fast turnaround helps your project move smoothly from design to approval.
