Sleepy light

In the evening your body produces melatonin (aka sleep hormone). Regular lamps and bright light suppresses the melatonin production. The Sleepy bulb has a spectrum that can be used in the evening. It is best to reduce the light brightness on your eye-level gradually in the evening. Bedside lamps and floor standing lamps are perfect fixtures to use with Sleepy.
