A highly-visible photoluminescent composition with long-lasting light output. The composition has photoluminescent particles suspended in an essentially clear medium that is adapted to transmit light emitted by the photoluminescent particles. The light emitted from the composition, averaged across at least three samples, exceeds the ASTM E2072 minimum brightness ratings at both 10 and 30 minutes by at least about three times. |
