Understanding Photoluminescence & Classifications
Ensure your buying the right quality Glow in the Dark Photoluminescent Signage. Photoluminescence signs provide an emission of light from the signs base material. This happens after the sign has had excitation from a light source. Time measurements between the absorption and emission may vary greatly from milliseconds to minutes, and the degree of luminance and its longevity will vary greatly depending on the quality of the Photoluminescent sign materials.
Photoluminescent Signs from UK Safety Store will meet or exceed The PSPA (Photoluminescent Safety Products Association) photoluminescent classification standards. The PSPA recommends Class B as a minimum requirement for effective use for safety way guidance systems.
Photoluminescent Classifications:
- CLASS D - Very high initial performance with photoluminescence remaining good for up to 1 hour.
- CLASS C - Higher performance in low light conditions
- CLASS B - High performance in low light conditions
- CLASS A - Cost effective photoluminescence
All Glow in the Dark Photoluminescent signs manufactured by UK Safety Store will meet or exceed the PSPA Photoluminescent Classification Standards. We also offer Extra-Glow "Class C" Photoluminescent signs for those looking for enhanced luminescence.
