Smart lighting is one of the simplest ways to give you more wireless control over your home. Philips produces the Hue line of products, which can perform some rather cool tricks that will make your standard lights envious. For example, they can be programmed to change colors when they detect smoke, or when your favorite sports team scores. We recently linked to a deal on Amazon for new Hue units, but if you're looking for more savings, Woot has refurbished models on sale for a larger discount.
