The Glow Night Light automatically turns on when it senses a dark room to keep you safe on your nightly travels without waking you up. An entry point to Casper lighting that delivers a gentle and comforting light for nighttime journeys and fears of darkness. The Glow Night Light helps minimize the sleep disruption of the inevitable trips out of bed in the night by gradually increasing light when it detects movement from further away, and dimming once you've returned to bed -- this keeps from shocking your system when turning bright lights on and off.
