Eyes
Multiple light sensors beyond rods and cones control circadian rhythms
How It Is
Light your body can feel.
Full-spectrum light carries biological signals that standard LEDs leave out. Here's how Lumenaros recreates the restorative patterns of natural sunlight — indoors, all day long.
The science behind what you feel.
The benefits of natural light aren't just emotional — they're biological.
Skin
Contains light-sensitive opsins that help regulate local biological rhythms.
Fat Tissue
Light exposure influences metabolism and energy regulation
The process
Step 1
Light Reaches the Body
Full-spectrum light contacts a child's eyes and skin, carrying important biological signals.
Step 2
Opsins Light Up
Light-sensing proteins throughout the body detect and respond to specific wavelengths.
Step 3
Signals Travel
Biological messages cascade through neural and hormonal pathways across the body.
Step 4
Rhythms Reset
Sleep deepens, focus sharpens, and development thrives with restored natural light signals.
A day with
Lumenaros
Pre-Dawn
Bright cool light signals energy and attention
The lower wavelengths (violet and indigo) activate alertness pathways, preparing the body and brain for an active day.
The spectrum difference
Traditional LEDs miss key wavelengths like blue, violet and indigo. Lumenaros brings them back, dynamically adjusting throughout the day to follow the same restorative patterns as natural sunlight.
What we've seen so far.
"I just feel better and less anxious when I’m in the room and the lights are on."
0%of teachers noticed positive change in behavior, attention, or mood
0%of parents described the lights as "softer" or "calming"
0%of parents were excited about having Lumenaros in their child's daycare room
The science behind the light.
Targets opsins in the body
Activates OPN3, OPN4, and OPN5 light-sensing proteins found in eyes, skin, & fat tissue to regulate biological rhythms.
Backed by 150+ peer-reviewed studies
Our technology is grounded in decades of research from Nature, Cell, and leading academic institutions worldwide.
Developed by experts at Cincinnati Children's
Created in partnership with world renowned pediatric researchers and ophthalmologists focused on child health.
“Light is one of the most powerful regulators of human biology — and we're only beginning to understand its full impact on development.”
James M. Greenberg, MD Professor of Pediatrics, Cincinnati Children's Hospital “Our research shows that specific wavelengths, particularly in the violet range, play critical roles in eye health that we can no longer ignore.”
Richard A. Lang, PhD Director, Visual Systems Group, Cincinnati Children's “At our core, we are driven by the opportunity to improve human health at scale. In collaboration with Cincinnati Children's Hospital, our team is translating leading-edge research into technology that can meaningfully impact millions of lives.”
