Lighting plays an important role in our daily life. It helps to bring brightness and visibility indoors and outdoors. It is used for general purposes and decoration which can create a pleasant atmosphere. Indoor lighting comes in many forms. Fluorescent light, LED, halogen and incandescent are all lights that can be used indoors. Fluorescent lights are long and thin tubes that use less energy than other forms of light and are often used in offices and other public facilities. LED bulbs may be the most energy efficient form of lighting and their bulb life lasts up to 10 times longer than that of traditional incandescent bulbs. Halogen bulbs use a gas-filled quartz envelope to produce a bright white light that is similar to sunlight. And finally, the incandescent bulb is the most common indoor lighting that is used in homes worldwide. Outdoor lighting is mainly used for security or decorative purposes. Typically, outdoor lights come in two types, either post mounted or wall mounted. Post mounted lights are placed at the end of a post and come in a variety of styles and materials. Wall mounted lights are attached to the wall and can be used to illuminate a porches, driveway, or walkway. Apart from these, solar lights are the most revolutionary form of lighting. They are cost effective, eco-friendly and reliable. Solar lights work by collecting energy from the sun during the day which is stored in a rechargeable battery. At night the battery powers the light and produces a bright light as long as the battery is charged and the LED bulb is in working condition. In conclusion, lighting is an essential part of our daily lives. Whether its used indoors or outdoors, lighting can be a source of security, visibility and beauty in our lives. By choosing the right type of lighting, we can enjoy the benefits of a pleasant atmosphere as well as save money on energy bills.
