Material, construction and direction of the light source are elements that settle the ideal purpose of a table lamp. With a focused and downward-facing light, the table lamp will highlight surfaces and can support tasks at desk or close to your favorite reading spot. With a diffused and upward-facing light, the table lamp provides a pleasant and intimate illumination that is perfect for establishing a relaxed atmosphere. A conical metal shade will direct the light whereas a translucent glass shade will emit the light in all directions. It is important to consider these factors when choosing the right table lamp.
