Abstract
This invention is a night light assembly containing a multiple LED light source and an electronic controller whereby the electronic controller causes the multiple LED light source to continually change its light output from a high intensity photopic light output to a low intensity scotopic light output in response to a transition from light to dark of an ambient light, matching a human eye response to a sudden decrease in ambient light.
