Night lights, also known as nursery night lights, are fixtures that emit a low wattage night-light glow used to illuminate dark rooms and hallways. They are often used to provide gentle illumination in nurseries or bedrooms for young children. Night lights are typically rated by the brightness and color temperature of the emitted light. Most night lights use LED technology to conserve energy and provide a longer life expectancy. LED night lights emit a soft light, usually of a warm yellowish color, which can be soothing or calming. The soft glow may also help parents look for their child in the dark, as the light isnt bright enough to wake them up. Night lights are available in a wide variety of shapes, sizes, and colors that can appeal to childrens preferences. There are many night-light options to choose from such as plug-in models, battery-operated lights, motion-activated lights, and even novelty lights. Many parents choose to purchase night-lights with a baby monitor, allowing them to keep an eye on their child at night. In addition to being soothing and providing extra nighttime safety, night lights also help children feel secure while sleeping in the dark. Having a night light on may also help children get back to sleep more easily if they wake in the middle of the night.
