SomniLight red nights lights are perfect for nurseries, hallways, bathrooms, and bedrooms. Blue light emitted by standard night lights has been demonstrated to interfere with sleep patterns, particularly in young children who sleep with a night light throughout the evening. Unlike most night lights, our low-blue, native red LEDs will not interfere with melatonin production during the evening, allowing you to find your way to the bathroom or nursery in the middle of the night without interfering with your circadian rhythm. SomniLight red night lights feature a dawn/dusk sensor, automatically shutting off in the presence of light.
