Photoluminescent signs or eco-friendly signage are available in various models according to requirement and purpose of use. From exit signs, safety equipment and floor safety signs, the range is varied as is the cost. The cost is primarily dependent on the intensity of photoluminescence which is directly correlated with the visibility distance. Photoluminescent signage is the most energy efficient signage. It requires no electricity and modern day photoluminescent signs offer greater visibility even in lower visibility conditions. Moreover, they do not have breakable parts so as to make them malfunction during falling debris.  Further, they do not require battery change or yearly operation checks.

Since photoluminescent signs help reduce electricity costs, companies can obtain LEED credits by using these in the buildings. The International Fire Code (IFC) and International Building Code (IBC) prefer photoluminescent signs for exit passageways and vertical exit enclosures.  

photoluminescent safety signs are produced from no less than 5 different grades of photoluminescent material with luminance decay properties classified according to ISO 17398.
