High reflectance ceilings maximize daylighting and reduce energy costs

To make efficient use of available daylighting, choose a ceiling panel with a high light reflectance rating. If a ceiling can reflect most daylight back into a space, the amount of artificial lighting can be decreased, saving you money. LR-1 rated panels reflect the most daylight back into a space — 75 percent or more. LR-2 and LR-3 rated panels do not reflect as much light and may not be suited for spaces where daylight maximization is a goal.
