When we design lighting for a space we often obsess over the lumens, the color temperature, and the energy efficiency. However, there is a crucial component that often goes overlooked until it cracks, yellows, or shatters: the LED diffuser. The diffuser is the shield. It is the interface between the raw, piercing light of the […]

How to Master Thermoforming with PMMA for Precision and Performance
In lighting design, materials need to do more than just look good — they must perform, adapt, and last. At Hexatron, we’ve worked with optical-grade materials for years, and when it comes to thermoformed diffusers, one material stands out: PMMA (Polymethyl Methacrylate). Why PMMA Is Ideal for Thermoforming PMMA, also known as acrylic, offers several advantages that make it […]
Hospital and Cleanroom Diffusers: A Complete Guide to Choosing the Right One
In critical environments like hospitals, laboratories, and cleanrooms, lighting plays an essential role not only in visibility and aesthetics but also in hygiene, safety, and human well-being. In such places, every component of the lighting system—from the housing to the diffuser—must meet strict standards for durability, optical quality, and chemical resistance. One of the most […]
Using Prismatic Sheets and Optical Films for UGR<19 Low-Glare Lighting
Achieving a UGR<19 compliant luminaire with a premium opal light effect requires the right combination of optical materials. In most high-quality LED panels, this effect is created by pairing a translucent or semi-opal optical film with a solid prismatic diffuser sheet. The clear prismatic sheet plays a critical role in beam angle control, helping reduce glare and maintain high luminous efficiency. Meanwhile, the optical diffusion film conceals visible […]
Environmental and Chemical Compliance in Diffusers: Meeting Global Safety Standards
In today’s world, diffusers for LED lighting are everywhere—from the panels in your office ceilings to the backlights on your smartphones and fixtures like street lamps. These materials, like polycarbonate (PC), polymethyl methacrylate (PMMA), or polystyrene (PS) offer incredible benefits: they’re lightweight and can be molded into complex shapes that traditional alternatives simply can’t match. […]
The Importance of GWFI in Diffusers for Lighting: Safety and Compliance with IEC 60695-2-12
When designing LED lighting, engineers must balance optical performance, thermal stability, and fire safety. One critical indicator for safe material selection is the Glow-Wire Flammability Index (GWFI), a global standard used to evaluate a plastic’s resistance to ignition. At Hexatron, our optical-grade materials are tested and certified to meet IEC 60695-2-12 standards, ensuring both optical […]
Thermal Expansion Calculator
When working with PMMA diffuser sheets it’s important to remember that plastics don’t stay the same size under all conditions. They expand in heat and contract in cold. This natural behavior, known as thermal expansion, can affect the final dimensions and fit of your sheets in lighting, display, or architectural applications. To make planning easier, […]
Using Prismatic Sheets and Films for UGR<19
Most of the premium UGR<19 compliant LED panels have an opal light effect. That is achieved by combining a translucent or semi opal film with a solid prismatic sheet. While the clear prismatic sheet will control the beam angle to reduce the glare, the film will hide the LED hotspots. The overall effect is a […]
What is Light Guide Plate (LGP): The Science of Light Distribution
A Light Guide Plate (LGP) is a thin, transparent optical sheet typically made from optical-grade acrylic (PMMA) or polycarbonate (PC). It is designed to distribute light evenly across its surface by guiding light from edge-mounted LEDs and emitting it uniformly through the front face. Originally developed for LCD backlight modules (BLUs), the LGP has evolved into a core optical component in LED panel lighting, architectural illumination, and decorative display systems. The unique value of an […]
Innovative Synergy of Micro Prismatic and Diffuser Films for UGR<19
Achieving UGR<19 Lighting with Micro Prismatic Sheets and Diffuser Films Creating visually comfortable indoor environments requires lighting systems that minimize glare while maintaining high efficiency. One of the most effective approaches is the combination of micro prismatic sheets and optical diffuser films, commonly used in LED luminaires designed to achieve a Unified Glare Rating (UGR) below 19, the recommended […]
