Are All Glow In The Dark Signs the Same?
No. The quality and specification of a photoluminescent signs material affects the strength of glow and duration of luminescence, resulting in large variences in the quality of glow in the dark signs on the market. The Photoluminescent Safety Products Association (PSPA), has developed codes and standards for photoluminescent products (classifications between the letters A - E), with Class A 's performance being weaker than that of a Class E rated photoluminescent product. The following table shows the PSPA's tested luminance & decay times.
PSPA Photoluminescent Classifications (Luminance mcd/m2):

At decay time 10 mins |

The PSPA recommends that a Class C rated product be used for Safety Signage. A Class C rated Photoluminescent Glow in the Dark sign may offer up to 3 times higher performance than that of Class B rated product, with Class C complying to ISO 16069 regulations.
