Elimination of hotspots
Unlike standard light diffusing materials, Led diffusing material ensures light from individual LED diodes are not visible ‘hotspots’. Light is diffused and dispersed throughout the material displaying light evenly.

Without a light source the discs are opal (off-white) in colour with a slight gloss surface finish. The temperature of the light when lit is dependent on the light source.

What are polished edges?
When we cut an acrylic sheet to size, the saw blade/router toolbit produces a matte finish on the edges of the panel. We use a technique called diamond polishing to polish the edges to a bright, smooth and glossy finish.
Our diamond edge-polishing machine polishes the edge of acrylic by running a rotating, diamond tipped wheel along the edge of the material.
You can read more about the techniques used to polish Perspex® in our blog post, The Ultimate Guide to Polishing Perspex®.
