18" Diffusers are available in Prismatic Curved, Prismatic Flat, White Curved, and White Flat.

Diffuser lens only. Trim ring not included.

All diffusers are made of durable acrylic.

Prismatic

The prismatic diffuser's surface contains several small prisms to help spread natural light evenly throughout the room. Prismatic diffusers will put out the brightest, natural looking light.

White

The white diffuser's surface is smooth and evenly spreads a softer tone of light. White diffusers put out less light than the prismatic diffusers and they look similar to a white florescent light.
