GREEN & YELLOW LIGHT
GREEN & YELLOW LIGHT
~520–590nm Yellow and green are the frequencies of growth and renewal — the wavelengths of chlorophyll, of sunlight at its most visible, of the nervous system finding its equilibrium. Operating... Read more...
BLUE LIGHT
BLUE LIGHT
~ 450–495 nm Blue sits at the shorter end of the visible spectrum — the colour of sky and sea, long associated with calm and clarity. It also has an... Read more...
Frequencies — What They Are, How the Body Responds, and Why the Carrier Matters
Frequencies — What They Are, How the Body Responds, and Why the Carrier Matters
What a frequency actually is A frequency is simply a rate of oscillation — how often something repeats per second. In physics, frequency is everywhere: Atoms vibrate Molecules oscillate Electrons... Read more...

Full-spectrum thinking
Biology evolved under full-spectrum light. Cells are accustomed to receiving multiple wavelengths simultaneously, not isolated bands. Firefly’s multi-wavelength architecture reflects this reality. Rather than relying on a single wavelength to... Read more...

NEAR-INFRARED LIGHT
NEAR-INFRARED LIGHT
~ 700–1000 nm Near-infrared sits just beyond what the human eye can see — invisible, yet deeply felt. Where visible light ends, near-infrared continues, carrying energy that the body absorbs... Read more...
RED LIGHT
RED LIGHT
~ 620–700 nm Red sits at the visible spectrum's longer wavelengths — the colour of fire, of dawn, of warning and warmth. In photobiomodulation, red light is strongly absorbed by... Read more...
Light, Wavelengths, and Why Power Matters
Light, Wavelengths, and Why Power Matters
What light actually is Light is electromagnetic energy expressed as discrete packets called photons. Each photon carries a specific amount of energy determined by its wavelength. Shorter wavelengths carry higher... Read more...
