The Science of Light and Sight
For millions of years, the human eye evolved for one light: the sun. Its full, balanced spectrum is our biological default. Today, we've replaced it with a harsh, incomplete substitute that forces our eyes to strain. We call it Ultra-Processed Light, and we believe it’s the real reason so many of us find reading more difficult.

Why your eyes work so hard indoors
The "white" light from a standard LED is an illusion. It is typically built on a harsh blue spike, and it is missing the vital wavelengths of colour that our eyes need to receive complete visual information.
When your eyes are starved of this information, your brain has to work overtime to fill in the gaps. This constant, hidden effort is the direct cause of the physical strain, headaches, and frustration you feel when trying to focus on a page. It's a problem of engineering, not of age.
-
Rebuilding the spectrum
To solve this problem, we had to re-engineer the light engine from first principles. Instead of a common blue LED chip, our system is built on a specialist Purple LED. This is a critical engineering decision that allows us to generate the wide-band energy needed to rebuild the full spectrum from its core components.
This energy excites a patented recipe of phosphors that regenerate the missing wavelengths, eliminating the harsh blue spike and filling the spectral gaps. It is a complex process, but the goal is simple: to create a complete, balanced spectrum that gives your eyes the light they were designed for.

The proof is in the data
Our claims are not subjective. The quality of a light spectrum can be measured, and the most revealing test is for deep red, known as R9. This is where standard LEDs consistently fail.
A commodity LED often scores a low or even negative R9 value, rendering reds as muted and brown. Our light engine scores an exceptional R9 value of over 90. This is a definitive, quantitative mark of a truly complete and balanced spectrum, a fact verified by the industry’s most advanced metric, TM-30.

Built for performance, not decoration
This is not a decorative object. It is a precision instrument, designed to reverse the hidden costs of poor light. Each one is built to last and guaranteed for five years. It is for anyone who refuses to let inadequate light dictate when they have to put down their book, their paintbrush, or their tools.
We are so confident in the difference it will make that we invite you to try one in your own home for 30 days. See and feel the difference for yourself. If you don't, we will collect it at our expense and refund you in full.
In the end, the fact that 98 out of 100 people keep their light is the only metric that truly matters.

Thank you for the Floor Light. I now sit and read in the evenings in a pool of pure daylight.
