Safety Path Photoluminescent exit signs are signs that are “charged” by daylight and/or artificial light from other light sources, then emit that stored light when external light levels fall.  Photoluminescence is a clean and safe non-radioactive source of light energy and when used in signs, no electricity or batteries are required for the sign itself, and they’re emission free.

With no electrical components, globes or batteries to fail, photoluminescent exit signs are long-lasting and require minimal maintenance. The signs don’t need to be connected to a Building Management System because there’s no legacy electrical components that can fail.

This transformational photoluminescent lighting technology offers major advantages to the building sector, in new-builds, renovations and retrofits.

New Builds

In new builds, specifying photoluminescent exit signs in the design phase reduces the size and extent of the emergency power supply and building management system. With no lights or batteries that can fail, they don’t need to be connected to the building management system.

Because photoluminescent exit signs have no lights or batteries that can fail, they don’t need to be connected to the building management system.

The installation of photoluminescent exit signs as part of a new build reduces the ongoing operating costs of the building, with less energy consumption, no emissions, reduced inspection requirements and no failed signs to be sent to landfill.

Renovations and Conversions

When renovating or converting an existing building, architects and designers can similarly use the opportunity to replace legacy electric exit signs with photoluminescent exit signs. This reduces the cost of the renovation or conversion by not requiring the emergency power supply and/or building management system to be extended or modified for additional exit signs. The owner benefits from reduced inspection, maintenance and energy costs.


Retrofitting photoluminescent exit signs helps companies achieve emission and energy reductions required as part of their environmental strategy or corporate social responsibility (CSR) strategy. With every electric exit sign that is replaced, a company can reduce its emissions by about 120 kg CO2e per annum. If you are in a commercial building, take a moment to count how many exit signs are on the floor of the building you are in right now.

Major Australian companies are retrofitting their extensive property portfolios with high-quality photoluminescent exit signs.


Photoluminescent exit signs are fully compliant with Part E4.8 of the Building Code of Australia (Volume 1 of the National Construction Code). The signs should be maintained in accordance with Specification E4.8 of the National Construction Code. They are also compliant with clause of AS/NZS 3000.
