What is Color Temperature Maintenance and why is it important?

Color temperature Maintenance (CTM) is a measure of how well a system can deliver reflected light without a color shift. The specific measured L*a*b color model performance parameters associated with a reflective surface are used to determine the spectral consistency of light as it is transferred through a tubular system. A high CTM denotes a product that produces minimal color / spectral shift of the light, which makes it a highly desirable light source for interior illumination. The Spectralight® Infinity Tubing used in Solatube® Daylighting Systems has a high CTM, which allows it to deliver the brightest, purest daylighting without major shifts over the course of the day or changes in season.
