A technical guide to optical diffuser films for LED lighting — covering PET vs PC substrates, transmittance grades, haze, how films fit within an optical stack, and applications across commercial, display, and architectural lighting.
A complete technical comparison of PMMA, polycarbonate (PC), and polystyrene (PS) for LED diffusers and optical sheets. Covers optical transmittance, impact resistance, fire ratings, UV stability, thermal behaviour, and application-by-application guidance to help engineers and buyers specify the right material first time.
