There are three basic types of lamp shade fittings: spider fittings, uno fittings, and clip-on fittings: Spider Fittings: Spider fittings are the most common type of fitting for table and floor lamps and are used with harps. There are three types of lamp shade fitters: spider, clip-on and UNO. Lampshades come in all shapes and sizes and can be paired with the right sized lamp base when fitted well. The right lampshade can provide an accent to your home's décor. You must know how to measure one to make sure it fits your lamp well. Harp/Spider Fitters The spider fitter is part of the lampshade itself. It sits on top of the harp and is secured by a finial. The height of a table lamp shade should be approximately the height of the base (to bottom of socket) x 60% up to 70%. The height of a floor lamp shade should be approximately the height of the base x 30% to 40%. Measure shade height along the slant.
Lampshades are made of fabric, parchment, glass, Tiffany glass, paper or plastic. Common fabric materials include silk, linen and cotton. Fabric shades are reinforced by metal frames to give the lampshades their shape, while paper or plastic shades can hold their shape without support.
To determine the size, measure the bottom diameter of the floor lamp base. A 10” floor lamp base should have an 18” bottom diameter shade. An 11” to 12” floor lamp base needs a 19” Jr to 20” Jr bottom diameter shade. A 13” or bigger floor lamp base will look good with a 20” to 22” bottom diameter shade.
A lamp harp is the component of a lamp to which the lamp shade is attached. It typically comes in two separate parts, a saddle which is fastened under the lamp socket, and the harp itself which consist of a lightweight frame attached to the saddle at its lower end and extending upwards to a point above the bulb.
Finials are stylized caps that fit over shades at the top of a lamp. They help secure the lampshade in place, provide a surface with which the lamp can be picked up from above, and complete the lamp or fixture's aesthetics.
There are three basic kinds of light bulbs on the market: incandescent, halogen, and CFL (compact fluorescent light).
Please don't match your lampshades. They can be different shapes, textures and colors. I don't go crazy on colors--I stick with white, cream and ivory (okay, sometimes gray or browns).
Types of Lamp Shade Fitters There are the three common fitters: Spider, Clip-On, and Uno. The spider lamp shade is the most common type of fitter for table and floor lamp shades. Spider fitters sit atop the lamp's harp (the U-shaped metal part of a lamp that fits around and protects the light bulb).
Parts of a Table Lamp (top to bottom): Lock: Locks the lampshade in place. Lampshade fitting: structural frame for the lampshade. Lampshade: Softens the light. Bulb: Provide the light. Harp: Vertical shade support and shade attachment into the socket. Socket shell: light socket for bulb.
The shade should be twice as wide as the lamp base, and one third of the total height of the lamp. So for a 6-inch lamp base, the shade should be at least 12 inches wide. And if the total height of the lamp (including the bulb and harp) is 24 inches, the shade should be 8 inches tall.
The right light If you need ambient light in the room or if you use the lamp for reading, go for a translucent shade. But if the lamp is just for decorative accent lighting, an opaque shade in a dark colour will be fine. If possible, test the shade with the light on.
How To Use an Uno Shade with a Harp & Finial Lamp 1 & 2. Unscrew the finial and then squeeze the harp to remove it. Pop the socket itself apart. Remove the top portion of the socket to reveal wire connections. Thread the wire through the ring of the uno shade and then through the socket cup. Reconnect the wiring, making sure to use an underwriter's knot for safety.
