What is night light?

A night light is a small, low-powered electric light kept on during the night in bedrooms and other areas to provide a subtle illumination. Night lights are often used to help children feel more secure and to help them avoid the fear of the dark, but it can also be used for adults or seniors who may wake up in the middle of the night and need illumination to move around.

Night lights come in various types, shapes, and sizes, from traditional plug-ins to battery-operated, portable, and color-changing ones. They usually emit a soft glow that provides enough illumination to help people avoid tripping over objects or walking into walls while remaining unobtrusive and not disrupting sleep. Some night lights also come with features such as automatic switching on and off, timers, motion sensors, and adjustable brightness levels.

Night lights are typically energy-efficient and use either LED or incandescent bulbs. LED bulbs are considered more efficient and long-lasting, while incandescent bulbs offer a warmer and softer light. Some night lights even come with interchangeable light bulbs, so users can switch between colors or adjust brightness levels according to their preferences.
