I get asked this a lot, being in the Lighting industry. The short answer is yes, Lighting is Feng Shui, sometimes good and sometimes bad.
Light equates to fire element, which is good in the south direction of your home. But most lights are made of metal, sometimes wood, sometimes crystal (represents water) sometimes ceramic (represents earth).
