The Science of Healthy Light
Understanding how light affects your body is the first step to better sleep. Here's what decades of research tells us about the hidden impacts of modern lighting.
The Blue Light Problem
Blue light, with wavelengths between 450-495 nanometers, is everywhere in modern life. It's emitted by smartphones, tablets, computers, LED bulbs, and televisions. While beneficial during the day for alertness and mood, exposure at night has significant consequences for your health.
Your body produces melatonin, the sleep hormone, in response to darkness. Blue light powerfully suppresses this production by signaling to your brain that it's still daytime. Research shows that even dim blue light can disrupt your circadian rhythm—your internal 24-hour clock that regulates sleep, hormones, and cellular repair.
Research published in the Journal of Applied Physiology found that blue light is more than 3 times more potent at suppressing melatonin than warmer light. A 2024 study of young adults showed that just two hours of LED screen exposure at night causes a 55% drop in melatonin and delays sleep onset by 1.5 hours.
"Blue light at night does more than disrupt sleep—it has been linked to increased risk of depression, diabetes, and cardiovascular problems."

The Hidden Danger of Flicker
Many people believe that switching to warmer-colored LEDs is enough to create a healthier home. But while warm tones partly address the blue light problem, they do nothing about a second, invisible issue that most manufacturers ignore.
Nearly all LED lights flicker—turning on and off hundreds of times per second. This flicker is too fast to consciously see, but your nervous system still responds to it, and the effects can be significant.
Research has shown that even imperceptible flicker above 100Hz can cause headaches, eye strain, and fatigue. A double-blind study of office workers found marked differences in headache rates when switching between high-flicker and low-flicker lighting—even though workers couldn't consciously detect any change.

The Solution
Our products are engineered from the ground up to eliminate both blue light and flicker, creating truly healthy lighting for your home.
Zero Blue Light
Our night lights emit only in the amber and red spectrum (590-700nm), completely eliminating the blue wavelengths that suppress melatonin. Use them in the evening without disrupting your natural sleep preparation.
Flicker-Free Technology
We use advanced constant-current drivers that eliminate flicker entirely. Our lights produce steady, stable illumination that won't strain your eyes or trigger headaches—even during extended use.
Blue blocking glasses
When we can't control the light environment, or when using screens at night, glasses that block blue light are very powerful and effective tools for emulating natural darkness in order to guarantee good, restorative sleep.
