Abstract: A method and apparatus for determining the circadian input of a light source includes selecting a circadian input to be measured based on an action spectrum corresponding to a wavelength sensitivity of photoreceptors for a circadian regulation system, where the circadian input is configured to stimulate a retinaldehyde photopigment, and for measuring spectral intensity across the action spectrum to determine the circadian input of the light source.

Abstract: The present invention involves a light system for stimulating or regulating neuroendocrine, circadian, and photoneural systems in mammals based upon the discovery of peak sensitivity ranging from 425-505 nm; a light meter system for quantifying light which stimulates or regulates mammalian circadian, photoneural, and neuroendocrine systems. The present invention also relates to translucent and transparent materials, and lamps or other light sources with or without filters capable of stimulating or regulating neuroendocrine, circadian, and photoneural systems in mammals. Additionally, the present invention involves treatment of mammals with a wide variety of disorders or deficits, including light responsive disorders, eating disorders, menstrual cycle disorders, non-specific alerting and performance deficits, hormone-sensitive cancers, and cardiovascular disorders.
