We use some plastic parts with self-glowing pigments. They absorb light during day time and glow in the dark. For quality control purposes we want to measure their brightness in the dark. Are there any standards for this purpose? How can we simulate this in the lab? Can ordinary lux meters be used for this purpose? The brightness decreases almost exponentially with time. How do we measure this drift?
Request suggestions for a simple gadget.
Best guess.
