With 2010 about to bid adieu, and you contemplating what things you could do to improve your home and spice it up a little, allow me to suggest ambient lighting. Start researching on "lighting fixtures for home" and see where some will do good in your abode.
They need not be expensive installations anyway. Maybe, a soft spotlight on your collectibles is all you need, or some back lighing in your shelf. Maybe you'd really benefit from a reading light in your bedroom that will cover the couch where you love to curl up in. And of course, there is always the garage or basement that can do with good white light to aid your chores and help prevent accidents.
