Frequently Asked Questions

What is an egg crate diffuser?

An egg crate diffuser is a lightweight lighting panel with a grid (cell) structure designed to control glare and spread light evenly. It is commonly used in commercial and architectural lighting, suspended ceilings, LED panels, and light boxes to reduce direct light visibility while maintaining airflow and brightness.

What are egg crate diffusers used for?

Egg crate diffusers are used in offices, retail spaces, hospitals, workshops, and commercial buildings to minimise glare, soften harsh lighting, and improve visual comfort. They are also used in HVAC return air grilles and custom lighting installations where light control and ventilation are required.

What materials are egg crate diffusers made from?

Most egg crate diffusers are manufactured from polystyrene, acrylic, or PVC. Polystyrene is the most common due to its low cost and light weight. Acrylic versions offer better durability and appearance, while PVC options are preferred in applications requiring higher impact resistance or moisture tolerance.

Do egg crate diffusers reduce light output?

Yes. Egg crate diffusers reduce glare by blocking direct line-of-sight to the light source, which results in some light loss. Typical light reduction ranges from 10% to 25% depending on cell depth, cell size, and material. The trade-off is improved comfort and reduced eye strain.

Are egg crate diffusers suitable for LED lights?

Yes. Egg crate diffusers are widely used with LED panels and troffers. They help control LED glare, especially in high-lumen fixtures, while maintaining even light distribution. Ensure the diffuser size and cell depth are compatible with the LED fitting to avoid uneven shadows.
