| BSI | 2017 | 28 |
This Technical Report defines metrics that can be used to evaluate and compare lighting conditions with respect to their potential to achieve non-image-forming, eye-mediated effects of light in human beings. This document applies to visible optic radiation in the wavelength range from 380 nm to 780 nm. This Technical Report does not give information for particular lighting applications. This Technical Report does not address health safety issues such as resulting from flicker, photobiological safety or the effects of non-visible optical radiation (ultraviolet and infrared radiation).
