The HD Pro is engineered to deliver the full, natural spectrum.
We use a specialist purple LED and a patented recipe of phosphors to fill in the gaps left by standard lights. This gives your eyes all the information they've been missing.
The result is simple: seeing clearly requires less effort.
Recreating the sun's full spectrum is the result of a 40-year obsession. This is no ordinary light; it is a precision instrument, engineered to deliver the complete, unbroken light your eyes were designed for.
Standard LEDs create glare with a harsh blue spike. We use a specialist purple LED to eliminate this flaw at its source.
Cheap phosphors leave gaps in the light. Our patented recipe of three rebuilds the full spectrum, ensuring colours are true.
When a light fails the R9 test for deep red, black text looks grey. Ours passes with a score of 92 to rebuild true contrast for sharp text.
Recreating the sun's spectrum is a complex engineering challenge. Our solution is Daylight Wavelength Technology™, a proprietary system built from three essential, uncompromising components.
We rejected the standard blue LED chip, the source of the harsh, glaring spike in all common LEDs. Our system is built on a specialist purple LED engine, eliminating the fundamental flaw at its origin.
The energy from the purple engine excites our patented recipe of three distinct, high-purity phosphors. This regenerates every vital colour of the natural spectrum, restoring the deep reds and filling the spectral voids that standard LEDs leave out.
This advanced system cannot run on standard circuitry. It requires a custom-engineered, 36-volt power system and bespoke electronics to guarantee absolute spectral purity and eliminate the invisible flicker common in lesser lights.
A look inside the deliberate engineering. from the specialist LED to our patented phosphors, required to build a perfect spectrum.
