- Modern LED lighting in historic buildings can create discomfort due to flickering, despite appearing warm.
- Pulse-width modulation (PWM) is a common cause of flicker in LED lights and digital displays, leading to eye strain and discomfort.
- 5-20% of people experience acute reactions to flicker, including migraines and nausea.
- Constant Current Reduction (CCR) is a flicker-free dimming method that reduces health risks and enhances visual comfort.
- Look for flicker-free certifications or high-frequency PWM (above 20 kHz) in lighting products to minimize discomfort.
- Calm Tech Certified™ products prioritize flicker-free standards to improve user well-being and productivity.
