Cost Advantage of Safe Glow® Photoluminescent Exit Signs

When assessing overall maintenance costs and power consumption of a facility, electrical exit signs may not be at the top of the problem resolution list. However, when taken in total, these numerous, small and seemingly innocuous devices can become very costly to maintain and operate.

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.

Architects and Developers

Those developing new facilities can save even more. By choosing photoluminescent exit signs, developers can save an average $450 per sign location by eliminating the infrastructure associated with electrical exit sign including:

By eliminating just the associated electrical infrastructure for 250 electric exit signs (a small facility) the new construction cost savings become evident, saving the developer more than $110,000 (250 x $450) in initial construction cost. Additionally, greener buildings can be achieved by arranging light fixtures so that 5 foot candles (54 lux) of light is present where photoluminescent exit signs will be installed - Not more fixtures, just more efficient placement.

Environmental Impact

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
