Lighting may be the most important aspect of your home's indoor appearance. Different lighting can make the same room feel cozy, lively, or peaceful. The right fixture in the right location can not only make a room more livable, it can also save money by significantly increasing the effective output (the delivered useful lumens) of your lighting. Fixtures with reflective surfaces and adjustable angles, for example, can double your useable lighting without spinning your meter another turn. Choose your lighting with care, and your comfort and savings will increase. Learn more about SAD season: If your gloomy mood matches the wintry skies, several approaches can help.
