Can I replace a plastic ceiling light cover with a glass one?

Q: Can I replace a plastic ceiling light cover with a glass one?

Yes, when the glass matches the fitter and the hardware can hold the heavier shade. Keep the lamp within the fixture rating. A sealed LED panel usually needs a new fixture.

Yes, if the glass cover uses the same fitter and the screws or finial can carry the extra weight. Plastic and glass are not interchangeable just because the shape looks similar. Keep the lamp at or under the wattage printed on the fixture.

The lip diameter matches.
The attachment is the same: screws, twist lock, or center finial.
The screw holes are not stripped.
The bulb does not touch the new cover.
Stay with an LED at or below the listed maximum.

If the plastic shade is clipped to a sealed LED panel, replace the fixture.

Will glass get hotter than plastic?

The lamp sets the heat. Stay inside the fixture listed lamp rating either way.
