Do Sunsred’s light therapy lights have Flicker issues?

Absolutely not! Sunsred knows that user comfort and eye safety are paramount, and we insist on making "Zero-Flicker" healthy light sources.

Many low-cost LED devices, due to the use of inferior driver power supplies, produce high-frequency flickering that is imperceptible to the naked eye but perceivable by the brain. Long-term exposure to such flickering may cause eye fatigue, headaches, lack of concentration, and even poses a potential safety risk of inducing photosensitive epilepsy.

All of Sunsred's red light therapy devices spare no cost in adopting high-quality flicker-free constant current driver power supply solutions, ensuring the output light is absolutely stable, pure, zero-flicker DC light.

This not only protects the user's eye health and nervous system but also provides a more comfortable, safer, and more professional treatment experience.

Sunsred insists on zero-flicker technology to guard your eye health and provide the most comfortable light therapy enjoyment!
