AGT™ Luminosity Ratings

Luminosity is an absolute measure of radiated electromagnetic power (light), the radiant power emitted by a light-emitting object.

Tested according to Germany DIN 67510 Part 1

Ultra-Grade Glow Stone luminosity in mcd/m² by decay time, tested to DIN 67510 Part 1
Type: Ultra Decay Time · mcd/m²

*Luminosity diminution: Glow Stone luminosity will diminish 1%–2% per year. For example, after 20 years luminosity will be at 60%–80% of original output.
