Lighting is possibly the most powerful tool you have when it comes to interior design. Why invest in beautiful furniture, rugs, paintings and accessories if you are living in the dark? When looking for a light fixture, think of yourself as a curator looking for a perfect piece of art.

Like art, a fabulous fixture can make a strong design statement as well as provide illumination for your space. Don't be afraid to add interest by using a modern fixture in a traditionally decorated room or vice versa. Find one special piece and build your room around it.

RIGHT LIGHT: Let Light Set the Tone

Create a room for living by carefully choosing light fixtures that not only illuminate well, but also add aesthetic appeal. By creating an artfully balanced space, you create a comfortable and more enjoyable space.

Use at least four layers of light to create a space that can smoothly transition from lively to low-key at the touch of a switch. While a dramatic fixture or eye-catching pendants may set the tone, additional lighting (for example, recessed and track lights, sconces, portables, etc.) may be needed to create appropriate illumination and comfort zones.
