Cove lighting ideas in a room can really add a touch of class. Well the most common form is the kind that is installed in a crown molding around a tray ceiling. It is not limited to that alone though. There are actually a lot of applications for cove lights. They can be installed above the crown molding in kitchens or under the toe kick. Over cabinets in bathrooms and the toe kicks there as well is another. Basically, anyplace there is a space for it, cove lighting can be installed and create a very nice effect.
