Lighting is an essential part of any living space. Good lighting can make a room look more inviting, inviting us to linger in it for longer and feel more at ease. It packs a psychological punch, driving away oppressive darkness and creating atmosphere. The right type and level of light will depend on the style of a room and the activities performed in it. While bright lighting may be suitable in a bathroom that needs to be well lit for safety, it is completely unsuitable in the bedroom, which should be cosy. In a living room some bright spots for reading and working may be necessary, but the overall light level should be balanced and comfortable. In modern homes, lighting has come a long way from a single overhead light to a selection of both hardwired and portable lamps providing an array of lighting options. Switches can be programmable, allowing lights to dim or turn on and off at preset times or in response to motion or sound. Specialty lights such as track lighting and wall washers can be used to create unique looks, or highlight artwork or other special features. High efficiency LED and other energy efficient light bulbs now provide good lighting while consuming very little energy, helping to reduce environmental impacts of lighting. Additionally, these newer bulbs last much longer than their incandescent counterparts, saving on energy and replacement costs. Lighting is an essential part of any living space. With careful selection of light fixtures and bulbs, its possible to create an inviting atmosphere that is both attractive and energy efficient.
