Harmful Light & Health: Better Lighting Solutions
Examine the often-overlooked hazards lurking in your home and office: harmful light and its impact on your well-being. This vital read details the detrimental effects of flicker, common in many LED lights and devices, possibly affecting your eyes and health. Learn about PWM (Pulse Width Modulation) dimming and why it might be causing you hidden discomfort. Discover a superior alternative: Constant Current Reduction (CCR) dimming. We unpack the science, the risks, and how to choose lighting solutions that prioritize your health and comfort. News Directory 3 delivers the insights ensuring you make informed choices.

Okay, I’ve analyzed the provided text. Here’s a summary of the key points regarding light flicker and its impact, along with the choice dimming method mentioned:
Key points:
PWM (Pulse Width Modulation) Flicker: Many LED lights, OLED displays, smartphones, laptops, monitors, and TVs use PWM to dim the light. This involves rapidly switching the light on and off.
Flicker Perception: While our eyes often can’t consciously see this rapid blinking, it can still cause discomfort, especially with lower frequencies. The human eye can detect flicker up to 2,000 Hz, particularly in peripheral vision.
Health Risks: Many popular devices have low kHz levels of flicker, which can pose health risks.
Constant current Reduction (CCR) Dimming: This is presented as a better alternative to PWM. It’s a method for dimming light that is easier on the eyes.
* Calm Tech Certified™: This certification ranks products based on various factors, including light flicker. They prefer “CCR Dimming” or require companies to display the frequency of their PWM dimming as “High-Frequency PWM Dimming (XX kHz)”.
In essence, the text argues that PWM dimming, while common, can be harmful due to the rapid flicker it produces. It promotes CCR dimming as a healthier alternative and suggests looking for products that are Calm Tech Certified™ or that clearly state their PWM dimming frequency is high.
