Disinfection
Numerous peer-reviewed studies demonstrate the effectiveness of visible 405nm light against bacteria, viruses, mold and fungi — the core science behind CleanWhite®’s continuous, chemical-free disinfection in occupied spaces.

Blue Light Health
Not all blue light behaves the same way. Understanding wavelength and intensity is essential to separating harmful exposure from the visible light used in CleanWhite® disinfection.
Eye Pain
Conventional high-energy blue light in the 415–455nm range has been associated with visual discomfort and retinal stress. CleanWhite® is engineered outside this harmful band, distinguishing disinfection-grade visible light from the blue light emitted by standard consumer LEDs and screens.Effect of light-emitting diodes with different color rendering indexes on the ocular tissues of rat

Blue Light Direct pain
Discomfort and hazard from light exposure are driven by a combination of intensity and wavelength, not wavelength alone. Research shows that carefully calibrated irradiance at 405nm can deliver germicidal effect while remaining within recognized visual comfort thresholds.Retinal phototoxicity and the evaluation of the blue light hazard of a new solid-state lighting technology

Circadian
Light is the primary cue that regulates the human body clock. Understanding how spectral composition across the day-night cycle influences circadian rhythm is central to designing healthier indoor lighting.

Frequently Asked Questions
No. This is one of the most important distinctions to make. UV light falls below 400nm and carries real safety concerns with prolonged exposure. CleanWhite® uses 405nm violet light, which sits within the visible spectrum. You can see it, and it's safe to work under. That difference is what allows CleanWhite® to run continuously in occupied spaces where UV systems simply can't.
Yes. CleanWhite® is certified to IEC 62471 Risk Group 0, the exempt category for photobiological hazard, meaning no restriction on exposure time for eyes or skin. It's designed to run around the clock in spaces where people live, work, and heal. There's no need to clear a room, schedule downtime, or wait for a cycle to finish.
Many bacteria and fungi naturally contain molecules called porphyrins. When 405nm light reaches them, those porphyrins absorb the energy and release reactive oxygen species inside the cell. That internal reaction damages the organism and inactivates it. Because the process works on the microbe's own chemistry rather than a surface coating or chemical residue, it keeps working quietly and continuously as long as the light is on.
No, and it isn't meant to. CleanWhite® works alongside your existing cleaning routines, not in place of them. Manual cleaning handles what you can see. CleanWhite® goes to work in the hours between, adding a continuous layer of protection on the surfaces your team already maintains. Think of it as reinforcement, not a replacement.
We believe in backing our claims with published science. The peer-reviewed studies behind CleanWhite's technology, along with our certifications and testing summaries, are available on request. Reach out to our team and we'll share the research most relevant to your facility type.
