A lamp shade is a decorative shade which typically surrounds a light source. Table lamps and floor lamps often use a lamp shade. The shade itself serves multiple functions, directing light upwards for ambient light, and downwards for nearby tasks. The funnel shape also helps heat to escape from the light bulbs. Some light may diffuse through the sides of the shade as well. The shade also protects your eyes from light-bulb glare and can become a part of your room's decorative style. Replacement lamp shades are a great way to refresh a lamp or light fixture. They attach to the lamp usually with a harp or fitter and finial.
A rectangle or square lamp shade appears to look like a rectangle when seen from above or below. Often the shade is wider than it is front-to-back. It features usually straight vertical flat sides and right-angled corners. It produces a modern geometric look which is ideal for a modern lamp base or one with a clean profile.
Contemporary and innovative, modern lighting underscores futuristic form and structure, and geometric or asymmetrical shapes. A modern lighting design instills functionality within an artfully streamlined form, radiating a reflective glow while providing clear and bright light. Modern Lighting complements a sleek, contemporary interior with straight lines, and can also create an agreeable contrast with transitional styles.

I was pleased with the quality of these 2 items, but as I only needed one, I decided to return them and keep my old lampshades.
