KastLite 12ft Bronze Acrylic Lamp Post Globe - Custom 4-5/8ft Twist

Our review of the KastLite 12' Bronze Acrylic Lamp Post Globe finds it best suited for owners of older or rare post lamp fixtures that need a custom fit. The single biggest reason to buy is the custom 4-5/8' twist-lock neck, which solves a common compatibility problem when standard globes will not seat properly. Reviewers noted the globe's clear, smoky bronze look and one-piece construction, and KastLite's U.S. manufacturing and UV resistant acrylic make it a practical replacement for outdoor fixtures where fit and weather resistance matter.

Key Features

• Custom Twist-Lock Neck: The 4-5/8' outside diameter twist-lock neck is manually customized to fit fixtures that refuse standard globes, ensuring a proper mechanical connection.
• Acrylic Construction: One-piece injection blow-molded acrylic with UV inhibitors provides a high transmittance of 92% while resisting yellowing in outdoor use.
• Weather Resistance: Water and weather resistant design keeps the globe serviceable on posts and outdoor fixtures in typical conditions.
• High Temperature Rating: The material handles continuous operating temperatures up to 90C, making it stable around warm lamp sources.
• Made in the USA: Manufactured domestically by KastLite, offering consistent quality control and support across all 50 states.

Who It's For

This globe is ideal for homeowners, maintenance crews, or restoration enthusiasts who have hard-to-find lamp post fixtures with a 4-5/8' opening and need a reliable replacement that will fit without extensive modification. It suits outdoor applications where UV resistance and a clear, smoky bronze appearance are desired.

Those who should look elsewhere are buyers who need a standard-size globe or expect included mounting hardware; a set screw is required but not included, and returns incur a 30% restock fee. If fit is uncertain, contact the seller before purchasing to avoid restocking penalties.
