An interesting potential advantage of LED lighting for buildings is the ability to add a new dimension of control–color–enabling adjustment of color temperature based on different uses of a space or time of day, while also providing high color rendering.
LED Journal has published an article on this topic by Muhamad Moussa, technical marketing engineer, and Patrick Durand, worldwide technical applications manager for Future Lighting Solutions. The editors summarize:
This article introduces new design concepts to develop a 6-inch commercial recessed downlight. The solution leverages an innovative approach for color mixing to create white light at several color temperatures (tunable white) while maintaining a high CRI across the color temperature range it covers. Furthermore, the proposed solution will meet and surpass the ENERGY STAR requirements for CRI, flux, efficacy and lifetime.
