Description

Polycarbonate Light Diffuser Sheets provide superior strength and impact resistance compared to traditional acrylic diffusers. Designed for lighting panels, skylights, and commercial fixtures, these sheets offer excellent light transmission while reducing glare and hot spots, ensuring even illumination in both indoor and outdoor environments.

Key Benefits of Polycarbonate over Acrylic Diffusers:

  • Impact Resistance: Polycarbonate is up to 250 times stronger than glass and significantly tougher than acrylic, making it ideal for high-impact or vandal-prone areas.
  • Heat Resistance: With a higher softening point, polycarbonate performs better under high-temperature lighting conditions.
  • Durability: Superior UV and weather resistance ensures long-term clarity and performance, even in harsh environments.
  • Safety: Its shatter-resistant properties make it a safer alternative in public spaces and industrial lighting systems.

Available in a range of thicknesses, patterns, and light diffusion levels, polycarbonate diffusers deliver a reliable, energy-efficient solution for modern lighting applications where strength and clarity are equally important.

Frequently Asked Questions​

What is a polycarbonate light diffuser?

A polycarbonate light diffuser is a translucent plastic sheet designed to spread light evenly and reduce glare or hot spots. It is commonly used in LED lighting, ceiling panels, light boxes, signage, and architectural lighting where controlled light transmission is required.

How does polycarbonate compare to acrylic for light diffusers?

Polycarbonate is significantly stronger and more impact-resistant than acrylic, making it better for high-traffic or vandal-prone areas. Acrylic offers slightly better optical clarity, but polycarbonate is preferred where durability, heat resistance, and safety are more important.

Is polycarbonate suitable for LED lighting?

Yes. Polycarbonate diffusers are widely used with LED lights due to their heat resistance, impact strength, and consistent light diffusion. They help eliminate harsh glare while maintaining good light output, even in high-temperature or commercial environments.

What light transmission options are available?

Polycarbonate light diffusers are available in various diffusion levels, typically ranging from high transmission (soft diffusion) to heavy diffusion for maximum glare reduction. Common finishes include opal, frost, and prismatic patterns, depending on the lighting effect required.

Can polycarbonate diffusers handle heat from lighting?

Yes. Polycarbonate has a higher heat resistance than acrylic, making it suitable for high-output LEDs and enclosed light fittings where heat buildup may occur. It maintains structural integrity and diffusion performance under elevated temperatures.
