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 drum lamp shade resembles a barrel or drum shape. The sides of the shade are completely vertical, or near to. They go straight up and down, which means the top and bottom of the drum lampshade are usually about the same size. This produces a somewhat more modern look, and equal amounts of light may emit out the top and bottom of the shade. Due to its cylinder shape, the shade easily allows bulb heat to escape. A cylindrical drum shade coordinates well with modern lamp bases or a base with a clean profile.
Informal and comfortable, this relaxed style accentuates an airy and unpretentious living space, evoking the feeling of a permanent beach cottage vacation. Casual Lighting uses clean and simple lines, subtle curves, natural textures, and decorative glass for a subtle elegance that doesn’t overwhelm the senses.
Sits on top of a harp or fitter, which is typically attached to a floor or table lamp. Spider-fitter shades sit on top of a harp fitter (a separate item). Uno fitter shades sit below the bulb with the uno fitter above. Clip-on shades clip directly onto the light bulb.
I have been looking for drum-style lamp shades for a long time before I came over these online. I love them, but the only think that is not represented by the pictures given was that the weave of the burlap is so much looser than it appears. Other than this minor con, they are perfect. I'm buying a couple more for my other lamps.
