Linear Control Film


Efficiently focus and aim light along one axis with our patent-pending micro-structured linear prism films. These products grant lighting designers flexible beam control options for symmetric and asymmetric applications including high bay lighting, linear spot lighting, wall-washers, wall-grazers, and signage.

Custom multi-lane layouts are available for certain specialty applications like ultra-wide or ultra-focused batwing-type aisle distributions. Our engineers can quickly develop these custom solutions tailored to your specific application, as well as provide usage recommendations for our standard offerings.

Typical distribution using LCF190 combined with 30 degrees diffusion in linear fixture.

DFLB-20 Asymmetric Linear Prism Film


20 degree linear asymmetric prism film that can be applied to display and lighting applications where asymmetric light bending is required. Can be used with collimated and diffused sources to create asymmetric “wall wash” distributions. Works with both linear and spot sources.

These products are available in pre-cut sheets or continuous, seamless rolls.

LCF is directional, but installation varies by fixture.  Typically, films that are flat in a fixture should be installed with the microstructures facing toward the lamp, while films that are curved (e.g. in a curved lens extrusion) should be installed with the microstructures facing away from the lamp.  However, we recommend testing both orientations in your fixture
