This application is a nonprovisional application of U.S. Provisional Application No. 63/562,784, filed Mar. 8, 2024, which is hereby incorporated herein by reference in its entirety.

BACKGROUND

Light fixtures, including chandeliers, typically include ornamental bodies. The ornamental bodies typically serve to enhance the visual presentation of the light fixture and the room in which it is mounted. The ornamental bodies typically include varying shapes based on a consumer's preference. The ornamental bodies are typically made from glass and are typically coupled to the light fixture. Supporting the ornamental bodies in the light fixture typically includes fitting the ornamental bodies with dowels or collars. The use of dowels involves boring holes into the ornamental bodies, which may cause fractures in the ornamental bodies. Collars typically involve adhesive, which can become brittle and fail. Collars, if made of polymer, may become brittle and fail.

It would therefore be desirable to provide improved apparatus and methods for light fixtures including translucent bodies.
