Lighting plays a very important role in our everyday lives. With the increasing use of electric lighting, it has become an essential element in our homes, workplaces and public spaces. The addition of light has transformed our lives and allowed us to live safer and more productive lives. Lighting affects the mood and atmosphere in any space. The proper lighting in the various rooms of your home can create an inviting atmosphere, while overly bright fluorescent lighting can create a sterile feeling. The color temperature of the light can also play a role. Warmer colors such as orange, yellow and red can create a relaxing mood while cooler colors such as blue and green can create a more vibrant and energetic atmosphere. Lighting is also important for security purposes. Employing outdoor lighting, such as motion-sensor lights, can help deter potential intruders and can alert you to suspicious activity. Proper illumination can create a secure public environment, reduce the risk of theft, and aid in the prevention of crime. Furthermore, lighting is important in many professions, such as photography, film and stage production, as well as industrial applications. By using lighting to accent particular features and to create moods, these professions are able to capture and create powerful experiences. In conclusion, lighting is a vital aspect to a safe and comfortable environment. Proper lighting can illuminate a room, create a mood, or increase security, making it an invaluable asset in any home or business. Nothing can quite compare to the effect which light can bring to our lives.
