Lighting is an important environmental factor that can significantly affect the distribution of living organisms, their phenology and behavior. Proper lighting also plays an important role in creating a comfortable living environment. When selecting lighting for different kinds of space, it is necessary to consider three aspects: brightness, color and energy efficiency. The brightness of lighting is determined by the intensity of light which should be suitable for various activities such as working, sleeping or entertaining. Its light color varies from warm white to cool white. Warm white lighting emits a yellowish light, creating a cozy atmosphere while cool white produces a bluish light, typically used for a commercial or technical purpose. For energy efficiency, LED lamps are becoming increasingly popular due to their long lifetime and energy-saving ability. Apart from that, there are different kinds of lighting for different scenarios. For outdoor lighting, safety lighting and decorative lighting are commonly used, while security lighting and spot lighting are often used indoors. Lighting can not only set a mood or atmosphere but also enhance the overall aesthetics of a space. For those reasons, choosing the right lighting for any space is always important.
