Lighting plays an important role in our life. It can not only provide us light to see, but also help us create a comfortable and safe environment. There are various kinds of lights now, from old-fashioned gas or electric lamps to the newer LED lights, we can choose the one that fits for our needs. When choosing lights for our home, we should consider factors including safety. Old style lamps may cause fire, which will put our home in danger. And for LED lights, we should choose the one with UL or CUL certification, which can guarantee our safety. Besides, energy efficiency of the lights should also be taken into account. New type of LED lighting is more efficient and more durable, which can save us money on energy bill. In addition, the types and brightness of the lights also depends on where you are going to use them. For places with human activities such as living room and bedroom, we need bright and comfortable lights to ensure our safety and make us comfortable; while for places where we just need lighting such as bathroom, what we need is just enough light to see, which will reduce unnecessary energy consumption. Overall, lighting can help us bring some convenience to our life, and make our home more safe and comfortable. Therefore, choosing the right kind of lighting is very important.
