Most people think of natural light when they consider brightening up a room with a window. But you lose this light source after dark. At night, window lighting can be used to simulate daytime illumination. The illusion of daylight on the interior space can be transformative. It offers a very different visual effect than traditional overhead lighting. From the exterior, the indirect lighting can be highly decorative at the same time making window lighting dual purpose.
Warm, full spectrum LED or fluorescent light around a window is just one option. You can choose any color to enhance the interior décor or mark a particular holiday with window perimeter lights. Rope lighting can be added along all four sides, the top, or just the window sill. Or, small lamps can be added at the corners. Button lights such as those typically installed under cabinets in the kitchen could be used for window sill lighting in some situations.
Window lights can also be directed toward the outside perimeter of the home for security reasons. These make it difficult for anyone to approach the window without being noticed. Burglars tend to shy away from well lit areas at night and look for easier targets.
Drapes, curtains, shades, blinds or any other window treatments can be accented with well placed lighting. In fact, light itself can be a window treatment. This is especially true for windows around a sunroom at night. The light reflections off the glass can give a mirrored effect to the room and make it seem much less gloomy.
