Y19 Prismatic Acrylic Light Diffuser

A premium diffuser for quality lighting applications


Y19 is the premier prismatic pattern. With a 4.7mm male prism running parallel and perpendicular to the length and width of the panel, Y19 provides good lamp cut-off to minimize lamp images and provide very low brightness at angles close to the horizontal.

Y19 Silver-Tint has a faint translucent tint that creates an elegant lighting effect. Y19 Silver-Tint produces lower brightness enclosure with improved visual comfort.

Y19’s high degree of luminance control makes it best suited for interiors involving more arduous visual tasks.


Acrylic material used in Y19 meets or exceeds recognised standards.  Under normal interior conditions, these lenses will perform satisfactorily for 20 years.

Y19 is manufactured from 100% Acrylic (Polymethylmethacrylate). Flammability Rating-UL94 HB.
