Philips has developed an in-school lighting system named SchoolVision. The firm has previously released findings from studies related to lighting configurations that are part of that system, as described here.
In the study reported here, Philips describes the implications of exposing students to a SchoolVision light setting they describe as the Relax condition (325 lx, 3,500 K). As the researchers detail, their research, which was conducted in real classrooms over the course of nine months, “showed a significantly stronger decline in fidgetiness and observed aggressive behaviors and a tendency toward increased prosocial behaviors within the intervention group.” In other words, when experiencing Relax lighting, students fidgeted less, were less aggressive, and behaved in a more positive, friendly way than kids in the classrooms without SchoolVision doing similar tasks/learning activities.
Pupils in the 3rd grade and in the 10th grade experienced the Relax light condition in their classroom (at times their teachers selected) or were assigned to classrooms that were comparable to the ones with SchoolVision (in terms of windows, etc.), except they were equipped with standard lighting (300 lx, 4,000K).
This research builds from “Empirical studies [that] indicate an improvement in communication and an increase in prosocial behaviors as a result of using warm, dimmed lighting in work environments.”
