Lighting is an important part of our daily lives. Lighting helps us wake up in the morning, provides light in dark places, sets the mood for activities, and keeps us safe at night. In homes, lighting can be used for both utilitarian and aesthetic purposes. For example, a bright ceiling lamp in the kitchen may help with cooking or a living room chandelier may be used to create a romantic atmosphere. In addition, glare-free industrial lighting can make working environments more comfortable. Outdoor lighting is also important for safety at night. Streetlights light our way and help pedestrians, motorists, and cyclists stay safe. Cars use headlights to improve visibility and signal to other drivers. Lighting can also be used to set the mood in all kinds of spaces, from public spaces such as parks and shopping malls, to private homes. Subtle lighting can help create a calming atmosphere, while bright lights can be used to energize and inject a place with a sense of fun. Lights are a key component of our everyday lives so, no matter how they're used, it's important that we pay attention to lighting efficiency, safety, and design.
