Battery-powered lighting refers to light sources that operate using batteries instead of being plugged into an electrical outlet. This type of lighting is versatile and portable, making it ideal for various applications such as camping, emergency situations, or home use. Common examples include flashlights, LED lanterns, and string lights. These lights come in various styles and brightness levels, often using LED technology for energy efficiency. Battery-powered lighting is convenient because it can be used in areas without access to electricity, and many models are designed to be lightweight and easy to carry.
