To install a diffuser on a lamp that uses a shade and finial, you typically unscrew the finial, place the diffuser, and then screw the finial back on.
This common method applies to lamps featuring a shade held in place by a finial at the top. The finial is the decorative knob or piece that screws onto the lamp's harp (the metal frame supporting the shade) to secure the shade.
Based on the provided reference, the process is straightforward:
Steps to Install a Diffuser Using a Finial
For lamps with shades and finials, including those with "larger cluster style sockets with a 1/8 IP style thread," installing a diffuser is a simple procedure.
- Unscrew the Finial: Begin by carefully unscrewing the finial from the top of your lamp shade. This allows you to lift or adjust the shade.
- Place the Diffuser: Put the diffuser on top of the shade. It should sit within or rest upon the top opening of the shade, depending on the diffuser type and shade design.
- Screw the Finial Back On: Once the diffuser is in place, screw the finial back onto the harp or lamp socket thread. This secures both the shade and the diffuser.
This method is effective for acrylic or other types of lamp diffusers designed to rest on top of a lamp shade and be held in place by the finial. The diffuser helps soften and spread the light from the bulb, reducing glare.
