THE SCIENCE

What is Flicker?

Flicker is rapid, repeated changes in light brightness. While sometimes visible to the naked eye, most flicker occurs at frequencies too fast to consciously perceive—but your eyes still respond. Traditional LED drivers use pulse-width modulation (PWM) to control brightness, creating a strobe effect at 100Hz or higher. Even though you can't see it, your eyes and brain must constantly adjust, leading to cumulative strain.

"Most LED lights flicker at 100-200Hz. PalFish achieves <0.5% flicker rate—completely stable."

THE SOLUTION

Flicker-Free Driver Technology

We developed a proprietary constant-current driver that eliminates flicker at the source. Instead of pulsing the LED, we regulate the current continuously for completely stable light output. The result is light that feels as natural as daylight—gentle on your eyes even during extended reading, studying, or working sessions.
