Lighting is an essential part of interior design. It has the power to set the mood and atmosphere of a room, as well as providing necessary illumination. Lighting can also be used to highlight certain features of a room, create an illusion of greater space and to create a more attractive and inviting living space. One of the most important aspects of lighting is understanding the different types of bulbs used. Incandescent bulbs are the oldest type and are still widely used; however, they produce a significant amount of heat and are not energy efficient. Halogen bulbs produce much less heat, but they are still not particularly energy efficient. CFLs and LEDs are the most energy efficient bulbs, and they also produce less heat, making them a popular choice. There are many different styles of lighting fixtures available to fit any decor. Wall fixtures can be used for task lighting, while chandeliers and pendant lights are great for general lighting and other decorative lighting effects. Ceiling fans with light fixtures are a great way to bring style and a cool breeze into a room. Dimmer switches can also be used, allowing you to adjust the brightness of the lights. No matter what type of lighting you choose, it is important to understand how to use it properly. Take the time to figure out how best to light your space in order to best illuminate the areas you need and create an inviting atmosphere. With lighting, you can create the perfect living space that is both functional and stylish.
