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 […]
UGR<19 LED Panels: Opal Film & Prismatic Lens Solutions
Achieving a UGR<19 compliant luminaire with a premium opal light effect requires precise engineering and the right combination of optical materials. Modern LED panels must balance efficiency, visual comfort, and aesthetic consistency, making the pairing of optical films and prismatic sheets essential for high-performance lighting systems. In most high-quality UGR<19 LED luminaires, the opal effect is created through a carefully […]
A Complete Guide to Eco-Safe LED Diffusers: RoHS , REACH, and More
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 […]
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 […]
Easy Thermal Expansion Calculator: Fast, Accurate Linear Expansion Results
Thermal Expansion Calculator: Easily Predict Heat & Linear Expansion of PMMA Sheets Materials like PMMA (acrylic) don’t stay the same size when temperatures change. They expand when heated and contract when cooled, which is why understanding thermal linear expansion is essential in lighting, display, and architectural applications. To make this process simple, we created an easy thermal expansion calculator that […]
How Opal Diffusers Films and Prismatic Sheets Achieve UGR<19 Low-Glare LED Panels
Modern lighting design places a strong emphasis not only on brightness but also on visual comfort. In offices, schools, retail spaces, and other workplaces, lighting that produces glare can cause eye strain, headaches, and reduced productivity. This is why UGR<19 compliant LED panels have become highly valued in commercial and professional environments. These panels are […]
Light Guide Plates (LGP): The Hidden Technology Powering Illumination
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 […]
Micro Prismatic and Diffuser Films Synergy 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 […]
