The best replacement for an 8-inch fitter glass shade is one whose fitter measurement matches the fixture’s opening—not just a shade with an 8-inch overall width. The Satco and KOR options below list fitter measurements close to 8 inches and are intended for mushroom-style fixtures. The 8-inch globe with a 4-inch fitter is a different size and is included as a measurement check, not as a match for an 8-inch fitter. Confirm the opening and shade dimensions before ordering.
| Product | Listed fitter | Best for |
|---|---|---|
| Satco 50-330 Mushroom Shade | 7-7/8 inches | A wider replacement mushroom shade |
| Satco 50/106 Drum Shade | 7-7/8 inches | A white drum shade with clear sections |
| KOR Mushroom Shade | 7.75 inches | Diffused light from a white interior |
| 8-Inch White Glass Globe | 4-inch opening | Fixtures requiring a smaller fitter |
| Westinghouse Mushroom Shade | Not specified | Shoppers considering a named 8-inch shade |
Satco 50-330 Mushroom Glass Shade
This replacement shade is designed for mushroom light fixtures. Its listed dimensions are 4 inches high by 9.5 inches in diameter, with a 7-7/8-inch fitter. That fitter is close to an 8-inch nominal size, but buyers should compare it with the fixture’s actual opening and existing shade.
Best for: Replacing a broad mushroom shade when the fixture takes a 7-7/8-inch fitter. It was selected because the listing provides both the fitter and overall dimensions, making it easier to check against an existing shade.
Limitation: Its 9.5-inch diameter may be larger than a buyer expects from an “8-inch shade” search. Measure the outside width as well as the fitter.
Satco 50/106 White Drum Shade
This white drum glass shade has an 8-3/8-inch diameter, a 7-7/8-inch fitter, and a 4-inch height. The listing describes a white exterior with clear sides and bottom. These details distinguish it from a fully opaque shade and help buyers compare the shape and light openings with their current fixture.
Best for: A buyer seeking a low-profile drum shade with a fitter close to 8 inches. It is a useful option when the fixture calls for a 7-7/8-inch fitter and the listed 8-3/8-inch diameter suits the space.
Limitation: The shade is only 4 inches high, and its clear sections differ from an all-white design. Check the appearance and dimensions against the original shade before choosing it.
KOR 8-Inch Fitter Mushroom Shade
KOR describes this as a replacement mushroom shade for ceiling lights and other fixtures that use a standard 8-inch fitter glass shade. Its listed fitter diameter is 7.75 inches; the shade is 4 inches high and 9.5 inches wide. A sprayed white interior is intended to diffuse light and reduce glare.
Best for: Buyers replacing a mushroom-style cover who want a white interior finish. It was selected for its stated use as a replacement and its clearly listed dimensions.
Limitation: The listed 7.75-inch fitter is not the same measurement as 7-7/8 inches. Confirm the fixture’s required fitter size rather than assuming the labels are interchangeable.
8-Inch White Glass Globe
The product name specifies an 8-inch white glass globe with a 4-inch fitter opening. The overall globe size and fitter size are different measurements: an 8-inch globe does not mean it fits an 8-inch fitter fixture.
Best for: Buyers whose fixture requires a 4-inch fitter and an 8-inch globe. It is included to make the sizing distinction clear when comparing search results.
Limitation: Avoid this shade if your fixture requires an 8-inch fitter. The available product information does not provide additional dimensions or finish details.
Westinghouse White Mushroom Shade
The Westinghouse 8375700 is identified as a white glass mushroom shade, and its name includes an 8-inch size. The provided product information does not specify the fitter measurement, so the name alone is not enough to confirm that it will fit an 8-inch fitter opening.
Best for: Buyers looking for a white mushroom-style shade who can verify the fitter details before purchase. Its listed style makes it relevant to this replacement search.
Limitation: The supplied details do not state the fitter diameter, height, or full shade dimensions. Check the product listing or confirm the measurement before selecting it.
Buying Guide
How do you measure an 8-inch fitter?
Measure the fitter opening—the part of the shade that sits at the fixture—not the widest part of the glass. Use the existing shade or fixture opening as a reference, and compare that measurement with the replacement’s listed fitter diameter. Product names may use rounded or nominal sizes, while specifications give a more precise measurement.
Does an 8-inch shade fit an 8-inch fitter?
Not necessarily. “8-inch” can describe the overall shade width, while “fitter” describes the opening that attaches to the fixture. The 8-inch globe listed above has a 4-inch fitter opening, illustrating why both measurements matter.
Which shape and finish should you choose?
Match the replacement’s shape to the fixture and the space available. A mushroom shade has a broad, rounded profile; a drum shade is shorter and more cylindrical. Also compare opaque white glass with designs that include clear sides or a clear bottom, since those finishes differ in appearance and how light passes through the shade.
What should you verify before ordering?
- Fitter diameter and how it compares with the fixture opening.
- Overall shade width and height, especially if clearance is limited.
- Shape and glass finish compared with the existing shade.
- Whether the listing provides enough dimensions to confirm a match.
Frequently Asked Questions
Is a 7-7/8-inch fitter the same as an 8-inch fitter?
It is slightly smaller by measurement. Check the fixture’s required fitter specification and compare it with the replacement rather than relying on a rounded size label.
What does fitter mean on a glass shade?
The fitter is the opening or attachment diameter where the shade meets the light fixture. It is separate from the shade’s overall width.
Can I choose a shade based only on its overall diameter?
No. Confirm the fitter measurement as well as the shade’s width and height. A shade with the right overall diameter may have an opening that does not match the fixture.
Which listed shade has the clearest dimensions for comparison?
The Satco 50-330 lists a 7-7/8-inch fitter, 4-inch height, and 9.5-inch diameter. The KOR shade also lists its fitter, height, and overall width.
