A wide-range of effective diffusion of light with high impact resistance.

Light Diffusers

Light diffusers filter and soften light, while protecting the light source and improving the overall appearance of the space. They are widely used in schools, hospitals, office blocks, train stations, prisons, shopping centres and other public buildings. Polycarbonate is typically used for light diffusers because it provides excellent light transmission, combined with heat and impact resistance and diffusion of LED hotspots.


Domes are equally effective light diffusers, but they also have a range of other applications – we have seen them used as eyes for giant mascots, plant holders and fish ponds, including playgrounds, safari parks, surveillance cameras, underwater devices, museum displays, decorations, props, and more. The only limit is your imagination!

Skylights allow you to provide natural light into a home or office space, providing the benefits of light and warmth while lowering the cost of electricity bills because a skylight can reduce heating costs on cold days and lighting costs on sunny days. There’s also that added aesthetic effect of having your room filled with natural light and a view of the sky.

Acrylic is the most common plastic used for skylights, in either clear or opal frosted, but you can also use Polycarbonate if you’re concerned about impact resistance.
