When we look at the physical composition of light (the so-called spectral composition or distribution) of standard white LEDs, we almost always see the same pattern: an extremely high and narrow “peak” in the blue part of the spectrum, approximately around 445–455 nm. This peak is the foundation from which all the light produced by the fixture originates.
The physical cause of this peak:
A typical LED diode is essentially just a blue chip coated with a layer of yellow phosphor. To create the perception of white light, the blue chip must shine very intensely. The result is inherently unbalanced light—it contains an unnaturally high amount of one specific wavelength (blue) while lacking others (see the problem of the cyan gap).
Why is this physical anomaly a problem compared to sunlight?
- High-energy harmful blue light (HBL): Wavelengths in this region (below 460 nm) are the most energetic in the visible spectrum. Long-term exposure to this concentrated “blue peak” is associated with increased oxidative stress on retinal cells, “digital” eye strain, and, with prolonged exposure, a potential risk of vision damage.
- Poor biological signal: This peak provides the body with a strong, but very narrow and incomplete signal. Meanwhile, the key wavelengths for regulating the circadian rhythm (around 480 nm) are missing. It’s like trying to charge a battery with the wrong charger—power goes in, but with negative side effects.
Spectrasol’s physical advantage: Balanced spectrum without extremes
Our patented technology is designed differently from the ground up. Our goal is not to create “some kind of white” using a phosphor trick, but to physically mimic sunlight as faithfully as possible. Therefore, our light spectrum has no aggressive or isolated blue peak. Instead, the energy in the blue part of the spectrum is evenly distributed. We reduce intensity in the hazardous HBL region (harmful blue light) and shift this energy into the beneficial azure and turquoise region. This achieves two key goals simultaneously: minimizing the risk to vision and maximizing circadian effectiveness—the positive signal for energy and vitality.
