Lighting is important for our daily life and activities. It provides illumination when the natural light is insufficient, making us able to finish the work indoors or outdoors. There are generally two types of lighting technology, incandescent lighting and fluorescent lighting, both used in different kinds of lighting fixtures. Incandescent lighting is a method of electric lighting. It works by passing electricity through a filament in a bulb, causing it to emit visible light. It provides a warm and cozy lighting effect, what people usually want for home decoration. Fluorescent lighting is an energy-saving technology that emits more visible light output than incandescents and require much lower amount of electricity. It is also commonly used in offices because it emits less heat and can reduce cooling loads. Whats more important is that appropriate lighting can relieve the strain on the eyes, prevent eyestrain, and improve visual performance. To make sure that your eyes are comfortable, it is suggested to adjust the lighting angle so that it is facing downwards, and adjust the light intensity so it is suitable for the eyes. Lighting is such an essential part of our life. To make the most of these different sources of illumination, we should choose the right type and adjust the lighting conditions to suit for our activities.
