Buying Guide

Match diffuser diameter to your pendant opening

Measure the pendant shade opening and choose a diffuser diameter that fits the 11.5–14" range common among round acrylic discs to avoid gaps or fitting issues

Prefer frosted acrylic for even light

Frosted acrylic discs scatter light effectively and reduce glare while remaining lightweight and shatter-resistant compared with glass

Check material thickness for durability

1/8" thick acrylic offers a balance of rigidity and low weight; thicker sheets resist warping but may add weight to the fixture

Consider round vs. disc shapes for appearance

Round diffuser discs deliver uniform radial diffusion suitable for circular pendants, ensuring consistent light distribution across the opening

Compare brands for consistent specs

Choose diffusers from manufacturers that publish clear diameter and thickness specs and have consistent user ratings to reduce guesswork when matching to fixtures
