Frequently Asked Questions

We understand you might have a few questions about Smarterlite products or technology. We’ve got the answers right here.

If you want to know how our photoluminescent technology or products work, how long they last, or whether they’re legally compliant, you’re in the right place.

Photoluminescence work by absorbing ambient light no matter whether it is natural or artificial light. In darkness, the stored energy is released as visible light. When used in Smarterlite’s Environmental Exit Signs and OHS Signs, it means the signs can be seen in the dark when the power unexpectedly fails. Unlike most emergency signage, this process is completely passive and does not require electricity or batteries to be visible during the period of darkness.

In Australia, the National Construction Code (NCC) permits the use of photoluminescent exit signs. Photoluminescent exit signs are compliant if they meet the specific requirements of the NCC. These requirements cover elements such as brightness, persistence, size and location.

Photoluminescent Exit Signs do not require an external power source such as electricity or batteries to be seen during darkness. They operate solely on photoluminescence, which means they charge when exposed to light and then release their ‘stored light’ when in darkness.


Smarterlite’s Hybrid Exit Signs co-mount a light source in the Exit Sign to charge the photoluminescence, so they can be used in poorly lit areas or where there’s energy saving room lighting that frequently switches off. Examples are utility areas, meeting rooms, lecture theatres and cinemas. This ensures the photoluminescence is always fully charged if there is a power failure in an emergency.

Our exit signs are always designed to meet the minimum requirements of Australia’s National Construction Code, which incorporates the Building Code of Australia, ensuring there is enough time to guide people to safety in an emergency in accordance with Australian regulations.

The lifespan of photoluminescent exit signs is determined by the quality of materials, UV light exposure, and environmental conditions. Smarterlite’s high-quality photoluminescent exit signs have a service life from 16+ to 30+ years, depending on the model.

Smarterlite’s Environmental Exit Signs are versatile and code-compliant, making them suitable for various building types, including commercial, residential, education, health, industrial and public facilities. Our Industries and Case Studies show the wide range of clients already creating safe, low-emission, lower-cost workplaces using Smarterlite’s technology.

Maintenance is minimal, requiring only a visual inspection by any competent person to ensure they’re not damaged or obstructed. In the case of hybrid photoluminescent exit signs the visual check also ensures that the integrated LED’s are also working.

Smarterlite’s Environmental Exit Signs contribute to emission reductions, delivering financial savings and sustainability benefits.

If you are interested in participating in one of the schemes, please contact us to discuss your needs. Conditions apply in accordance with State Government regulations.

Testing for photoluminescent exit signs is simple, being a simple test to ensure the sign is in place, legible and not obstructed to ensure the sign is visible and legible during emergencies. Unlike standard exit signs, photoluminescent exit signs do not need a 90-minute battery load test, helping reduce testing time.

Yes! Brightness does not equal visibility; hence modern standards like Australia’s National Construction Code are written around visibility. The size and luminance of photoluminescent exit signs is intentionally designed to strike a balance between providing adequate visibility and avoiding excessive brightness that could potentially distract occupants or create glare in a smoky environment. The purpose of these lights is to provide safe and clear guidance in emergency situations without causing discomfort.

Photoluminescent exit signs are approved for implementation across Australia as part of the National Construction Code, and Smarterlite’s Environmental Exit Signs are installed nationally by leading corporations.

The use of photoluminescent exit signs is a global movement in fire safety. In Australia they are approved by fire authorities and building authorities in each State and Territory as part of the process of updating the National Construction Code. The luminosity and size of photoluminescent exit signs ensures they remain visible in emergencies offering a reliable and visible evacuation path for occupants.

Smarterlite’s Environmental Exit Signs are trusted and used by a diverse number of industries and organisations. This includes businesses, schools and colleges, healthcare facilities and government buildings. You can find more information in the industries and case studies section.

Smarterlite Environmental Exit Signs cost you no more to buy and reduce your operating expenditure significantly over time. Use our Financial Calculator to understand what you’re already paying and how much you could save.

Smarterlite’s Environmental Exit Signs are designed to meet safety standards, including relevant parts of AS2293 as required by the National Construction Code. This ensures they adhere to established guidelines for exit signs such as where they must be placed and what they look like, guaranteeing their effectiveness in critical situations. Most of AS2293 does not apply to photoluminescent exit signs because AS2293 is written around the needs of powered electric-battery exit signs and how to reduce their risk of failure.

Smarterlite’s Environmental Exit Signs do not have batteries. Batteries and their associated circuitry are one of the primary causes of failed exit signs and Smarterlite’s sign technology eliminates electric batteries.


Smarterlite’s Environmental Exit Signs operate independently of battery power, relying instead on photoluminescent light, making them energy-efficient and reliable.


Did you know that battery failures are often excluded from warranty repairs for electric-battery exit signs?

Unlike older technologies like Tritium (which did involve radioactive components, but weren’t common in Australia), our photoluminescent signs do not use and have never used radioactive materials. They are completely safe, using the safe natural science of photoluminescence.

Yes! Smarterlite Environmental Exit Signs are completely recyclable, contributing to eco-friendly practices by reducing waste and promoting responsible disposal. They also reduce eWaste and plastic waste by about 2kg per sign. Smarterlite’s hybrid exit signs are designed to be repairable.

The Australian Standard for exit signs is Australia’s National Construction Code (NCC), which incorporates the Building Code of Australia.


The NCC allows Photoluminescent Exit Signs in accordance with Specification 25 in the NCC, or powered old-tech electric-battery exit signs and emergency lights in accordance with Australian Standard AS2293.


Australian Standards are subservient to the National Construction Code of Australia, in that they cannot conflict or contradict it, and they cannot and do not over-ride it.



Electric-battery exit signs do not have batteries that can be changed by anyone other than a licensed electrician.


There’s also no standardisation of exit sign batteries, with each exit sign manufacturer having their own range of custom batteries. Instead, you’ll need to have an electrician replace the whole sign, and dispose of the failed sign as licensed eWaste.


To avoid this happening again, tell your electrician to use a Smarterlite Environmental Exit Sign. Our signs don’t have electric batteries to fail and are fully compliant with the National Construction Code (NCC), which includes the Building Code of Australia.


Contact us and we’ll help you buy a replacement sign that matches your existing sign, for your electrician to install.

No, Australia’s National Construction Code allows battery-free photoluminescent and hybrid photoluminescent exit signs as well as powered electric-battery exit signs.
