Lighting & Signage Sheet

Diffusers, lightbox faces and illuminated fascias — even output with no visible LED lines.

Illuminated signage lives or dies on evenness. A face that shows the LED strip through it reads as cheap regardless of the graphics, and the fix is always the same: match the sheet to the cavity, not the other way round.

We supply both sides of this — PC diffuser sheet at above 95% diffusion uniformity for luminaires, and opal acrylic in several opacity grades for sign faces.

Questions buyers ask

Why can I see the LEDs through my sign face?

The sheet is too transmissive for the cavity depth and lamp spacing. Either move to a higher-hiding opacity grade or deepen the box. Send us both figures and we will send samples to test.

Acrylic or polycarbonate for sign faces?

Acrylic for most signage — brighter, better colour stability, cheaper. Polycarbonate where vandalism or impact is a real risk, accepting slightly lower brightness.

Will illuminated sheet yellow over time?

Not from LED light with virgin material. Yellowing comes from recycled base resin or from lamps running hot against the face.
