Photoluminescent exit signs with an integrated light source, known as hybrid exit signs, don’t need 100 lux on the face of the sign.

The fallacy that all photoluminescent exit signs need 100 lux on the face of the sign comes about from the requirements of Australia’s National Construction Code (NCC). However NCC (2019) was written before the development of hybrid exit signs that co-mount a light source into a photoluminescent exit sign.

Standards Australia’s Technical Specification 5367:2021 has a minimum luminance of 20 cd/m2 for the photoluminescent material under normal power conditions, which corresponds to external lighting in accordance with the NCC. Consequently, any photoluminescent exit sign with co-mounted light source that meets the requirements of Standards Australia’s TS5367:2021, known as a hybrid exit sign, does not need 100 lux on the face of the sign.

Safety Path has photoluminescent exit signs and hybrid exit signs that comply with the requirements of the National Construction Code and Standards Australia’s Technical Specification 5367:2021 respectively. Safety Path’s hybrid exit signs are the industry leaders in minimal power-consumption, and are available in a range of sizes for use in workplaces such as offices, factories, schools, shopping centres, hospitals, warehouses, data centres, mining camps and chemical plants.

Safety Path also provides photoluminescent workplace safety signs, compliant with the requirements of Australian Standard AS1319-1994 and photoluminescent linemarking and coatings for safety when the power fails in a blackout or brownout.
