Daylight Wavelength Technology™
We have spent the last 40 years solving a single problem: how to fix the flawed artificial light that now dominates our indoor lives. Our technology offers a solution. It doesn’t only imitate the colours of daylight at different times, but crucially it closely replicates the full, balanced natural visual spectrum, which is where the magic happens. Click here to see the evidence.
How we bring daylight indoors
-
A high-fidelity foundation
The harsh blue spike in standard blue LEDs creates glare that reduces clarity and causes us to strain. This is what makes LED car headlights hard to look at.
Our technology is built around a rare specialist purple LED; a deliberate choice to eliminate the primary cause of damaging visual noise at its source.
-
The complete spectrum
Standard artificial lights project a fractured signal, with too much blue and voids where reds should be. This drains contrast, and makes accurate colour rendition impossible, forcing our brains to work harder to decode the words and colour hues on a page.
A recipe of phosphors rebuilds this missing information, delivering a full, continuous spectrum. Eyes get the complete picture, and the brain doesn't have to work so hard.
-
Proven fidelity
Brightness is not a measure of light quality. The old CRI metric cannot be relied upon when it comes to LEDs. Only the international TM-30 standard offers us an accurate, rigorous test for LED light fidelity.
The data is clear: a colour fidelity score of 98/100 and a deep red rendering score of over 90. Objective proof behind why text appears crisp, colours true and the feeling that your eyes can relax.

It's like reading in intense daylight, but without any glare or stray reflections - fantastic!
Mr. Hambidge, Milford Haven

I can see more easily with less eye strain because the light is much more like daylight.

When sitting under this light it feels as though you are bathed in sunlight. Well worth the money.
Mrs. Nicholls, Shropshire
