Night Light, a magical device that is designed to brighten up our lives. It is used mainly in bedrooms to allow a subtle flow of illumination when darkness falls. Night lights work by using a light source inside a shield that contains a reflective lining. This lining acts like a miniature mirror, pushing and bouncing the light all around the room ensuring it's distributed evenly and with minimal heat generation. Inside each night light is either an LED or CFL (Compact Fluorescent Lamp). LED stands for Light Emitting Diode and CFL stands for Compact Fluorescent Lamp. Night lights have several advantages. Firstly, they make your rooms look great. Whether you just want a simple, warm glow to set the mood, or you're going for a more futuristic look with colored LEDs, these lights make a great addition to any bedroom. Secondly, they are incredibly energy efficient and use minimal electricity, meaning they will not drastically increase your energy bills. Finally, they provide a safe, soft light in the dark – much more safely than leaving a large light on – and can even be programmed to switch off automatically after a set period of time. All in all, night lights have a lot of excellent benefits and are a great addition to any bedroom. They allow for subtle illumination, are energy efficient, and look great too!
