Frequently Asked Questions

How do I choose the correct replacement globe size?
Measure the diameter across the widest part of your existing globe (edge to edge). For necked globes, also measure the inside diameter of the neck or opening. Round up to the nearest standard size.

What are the differences between acrylic and polycarbonate light globes?
Acrylic globes provide excellent clarity and resist yellowing, making them a great choice for decorative and residential use. Polycarbonate lamp globes are stronger and more impact-resistant, perfect for outdoor, public, or high-traffic areas.

Which finishes are available for lamp globes and covers?
We offer clear, white, prismatic, smoke, bronze, and frosted finishes. Clear globes maximize brightness, while prismatic and white globes diffuse light for softer, even illumination. Smoke and bronze finishes add a unique decorative touch.
