During manufacture, the PolyGlow™ aggregates have had a photoluminescent compound added into the raw material. This allows them to absorb light and then emit that light as a soft glow during darkness. Exposure of around 30 minutes will give a glow time of up to 12 hours. The glow starts off brightly and diminishes as the night progresses. The photoluminescent compound, strontium aluminate, has a cycle life of at least 10 years and is not radioactive.

The brightness of the glow emitted by Photoluminescent aggregates are effected by their surrounding environments. Put simply, the darker the night, the brighter they glow. For instance, if you have a street light or a bright moon present, the brilliance of the glow will appear less than it would in a darker setting. PolyGlow™ Stones work best when placed under a direct light source for charging during the day.
