The negative health impacts of LED flicker and the stroboscopic effect (temporal light modulation) are now widely recognized, linked to eye strain, migraines, and reduced visual performance. Consequently, there is a strong regulatory and market push towards truly flicker-free lighting, especially in workplaces, schools, and healthcare. Leading manufacturers are designing drivers and control systems that maintain extremely low levels of temporal modulation (measured by metrics like Percent Flicker and SVM – Stroboscopic Visibility Measure) under all dimming conditions. This requires high-quality electronic components and sophisticated driver design. Specifications from large buyers and standards bodies are increasingly mandating stringent flicker performance. This shift is moving flicker mitigation from a technical footnote to a fundamental quality and wellness attribute, ensuring that the energy efficiency of LEDs does not come at the cost of occupant health and comfort.
