A lampshade typically fits onto a lamp using a spider, harp, or clip-on mechanism that attaches to the lamp's bulb socket or the lamp's body.
Here's a breakdown of common fitting methods:
-
Spider fitting: This is the most common type. A spider (a wire framework) sits on a harp (a wire support that straddles the bulb socket). A finial screws onto the top of the harp, securing the lampshade in place.
- The spider rests on the harp.
- The finial screws onto the threaded rod of the harp.
- Different sized harps are available to adjust the lampshade height.
-
Clip-on fitting: Clip-on lampshades have small clips that directly attach to the light bulb. These are often used for smaller lamps or sconces.
- The clips securely grip the light bulb.
- These are usually for smaller, lighter shades.
-
Uno fitting: This lampshade sits directly on the lamp's bulb socket, held in place by tightening a decorative ring or socket cover.
- The lampshade has a recessed area that fits snugly around the socket.
- A decorative ring screws onto the socket to secure the shade.
Key Considerations for Choosing a Lampshade Fitting:
- Lamp Style: The lamp's design often dictates the fitting type.
- Shade Size and Weight: Larger, heavier shades typically require a more robust spider and harp system.
- Personal Preference: Some find certain fitting methods easier to use than others.
It's essential to ensure the lampshade is securely fitted to prevent it from wobbling or falling off, potentially damaging the lamp or creating a safety hazard. Remember to choose a lampshade size that is proportional to the lamp base. A general guideline is that the lampshade height should be approximately 2/3 the height of the lamp base.
