TL;DR: Exposure to blue-enriched white light during daytime workhours improves subjective alertness, performance, and evening fatigue.

TL;DR: High correlated colour temperature fluorescent lights could provide a useful intervention to improve wellbeing and productivity in the corporate setting, although further work is necessary in quantifying the magnitude of likely benefits.

TL;DR: It is shown that pupillomotor and circadian responses of mice relying solely on melanopsin for their photosensitivity can indeed be accurately predicted using the 480-nm nomogram, and that measuring light in these terms predicts the melanopsIn response to light of divergent spectral composition much more reliably than other methods for quantifying irradiance or illuminance currently in widespread use.

TL;DR: The data show that light at home in the evening affects circadian physiology and imply that the spectral composition of artificial light can be modified to minimize this disruptive effect on sleep and circadian rhythms.

TL;DR: In this article, the authors explored the electrowetting behavior and the fluidic motion as a function of several parameters, including voltage, colored oil film thickness, oil type, and device size.
