Outdoor lights, also known as street lamps, indoor or outdoor lights that decorate buildings, yards and parks, are an important part of city lighting. Outdoor lighting also plays a role in keeping buildings and gardens illuminated at night and providing nighttime guidance for pedestrians. Outdoor lights introduce an aesthetic beauty to an environment. Depending on the type of lighting used, the look of a home or garden can be enhanced. Different types of outdoor lights create different atmospheres. For example, soft white lights will create a gentle, romantic atmosphere and cause less eye strain, while colorful, sparky lights will create a cheerful, festive atmosphere and be more suitable for partying. Outdoor lighting also has an important practical function. Pedestrians and drivers rely on outdoor lighting at night to navigate the road, follow directions, and even recognize certain storefronts. When a customer notices a well-lit store, they may be more likely to enter it. Outdoor lights provide safety and security in important public spaces and during certain events, such as concerts and film screenings. Finally, outdoor lights can be energy-efficient if used correctly. LED outdoor lights are available with the same intensity as halogen lamps yet use much less energy, providing the same light at a fraction of the cost. LED outdoor lights can be adjusted to provide only the light needed in a specific area and be turned off when not in use, making them more efficient than traditional lights. Outdoor lights can be both a practical and aesthetic necessity in any environment. They provide visibility in otherwise dark places, providing safety and security as well as a way to beautify an environment.
