The table below provides an overview of the typical cost of ownership between various electric sign technologies and Safe Glow’s photoluminescent exit signs. The summary highlights the annual cost of ownership for each based on a single sign, 250 signs (medium sized facility) and the lifetime cost of ownership (25 years) for 250 signs.

Those developing new facilities can save even more. Greener buildings can be achieved by placing light fixtures where they are needed to ensure the 5 foot candles of light is present where photoluminescent exit signs will be installed.
By choosing photoluminescent exit signs, developers can eliminate the infrastructure and cost associated with electric exit signs including:
Not only do electrical exit signs have a high cost of ownership, they also contribute to global CO2 pollution, which many believe negatively impacts our environment and our future. Click here to learn more and view our sustainability page
