9. Tunable Lighting in Education. An experiment performed at Kazan State Power Engineering University with two types of lighting in two classrooms, one classroom equipped with color fusion LED series with adjustable color temperature and lighting control system and the other classroom with standard neutral fluorescent luminaire where indicators of performance, well- being, and mood were measured. The effects were measured at 2800K, 4000K and 5800K with LED lights and neutral color temperature of 3000K to 3500K with fluorescent lights. Kazan State Power Engineering Study

10. Tunable Lighting in Education Kazan State Study: The results indicated the increase in performance at T c =5800K with LED lights compared to fluorescent lighting, a relaxing trend was observed in the students with the LED lights tuned at T c = 2800K.

18. Tunable Lighting in Education 18 What is circadian rhythm? A circadian rhythm is a biological process that displays an endogenous, entrainable oscillation of about 24 hours. Although these rhythms are built-in but they are adjusted to the local environment by external cues which include light and temperature. Light mostly drives our circadian system. Certain wavelengths of light affect this circadian system of our body more than the others.

19. Tunable Lighting in Education Circadian Lighting potential in Schools  Lighting impacts humans in a variety of ways.  Lighting can promote well being and strengthens concentration levels.  Lighting can have a positive influence on learning.  Daylighting  Tunable color- cool / warm  Light can support our circadian rhythm (day/night rhythm) and control biological processes in our body.  Human biological rhythm is controlled by a "body clock", on which light has a crucial influence.  Light supports the sleep-wake cycle by telling our body when day turns into night.  Cool cold-white light with high levels of 460nm blue, similar to daylight, makes us alert and active.  Warm-white light, with less 460nm blue, has a relaxing, soothing effect
