01 ⸺ The Spectrum
Conventional LEDs have a blue light problem. CleanWhite Pure doesn't.
Every conventional white LED produces light by exciting a phosphor with a blue pump wavelength, typically centered at 450nm. That blue pump wavelength never goes away: it is present in the light every hour the fixture is on, and it is the source of many photobiological concerns documented in clinical and occupational-health literature, including elevated blue-light hazard scores, melatonin suppression, circadian disruption, and visual discomfort under prolonged exposure.
Some manufacturers have responded by adding a secondary 470nm emission, marketed as “circadian support.” However, 470nm sits near the melanopsin absorption peak and introduces a second blue spike with its own photobiological consequences.
CleanWhite Pure eliminates both. Its 405nm chip produces white light through phosphor conversion with no concentrated blue peak anywhere in the output. The result is a smoother, broader spectral power distribution, and that cleaner spectrum is why CRI 90+ is achievable without engineering compromises.
Spectral Power Distribution
Visible spectrum, 380nm to 700nm
CleanWhite Pure has a narrow peak at 405 nanometers and a broad secondary spectrum around 600 nanometers. The conventional LED has a flat-topped primary peak between the 450 and 470 nanometer reference guides.
This graph may/is not reflective of our actual spectrum.
CleanWhite Pure vs Conventional LED
405NM
CleanWhite Pure, 405nm chip
Single-chip 405nm emission converts through phosphor to produce CRI 90+ white light with no blue peaks. The cleaner spectral base enables both the higher CRI and the IEC 62471 RG 0 safety rating; they come from the same design decision.
450NM
Conventional LED, 450nm blue spike
The 450nm pump spike is not a design choice. It is an inherent byproduct of the standard phosphor excitation method. It cannot be filtered out without sacrificing output. It is present in every conventional white LED at full intensity, every hour the fixture operates.
470NM
“Circadian” LEDs, the 470nm problem
Products that add 470nm for circadian stimulation introduce a spike near the melanopsin absorption peak (~480nm). 470nm does drive alertness, but it also suppresses melatonin and disrupts sleep in evening and nighttime environments. It is not a clean solution.
Color Rendering Index (CRI) 90+: because better light starts with a better spectrum.
Color Rendering Index (CRI) measures how accurately a light source reveals the true colors of what it illuminates, relative to natural daylight. Conventional LEDs score CRI 80–85. Their heavy blue pump spike narrows the effective spectral base, creating gaps in the output that can cause colors, including skin tones, food textures, and clinical tissue, to appear cool or slightly flattened.
CleanWhite Pure achieves CRI 90+ because its 405nm chip drives a broader, more even phosphor conversion across the visible spectrum. The output fills spectral gaps that conventional LEDs miss, producing more accurate, more natural color rendering without additional hardware or tuning.
In practice, CRI 90+ means surgical staff can assess tissue color with greater confidence. Dental professionals see shade and gingival tone accurately. Educators and office workers experience less visual fatigue. Grocery retailers present produce and protein that looks genuinely fresh. The light does its job better because the spectrum is cleaner.
02 ⸺ Where CRI 90+ matters by vertical
01
Healthcare & Surgery
Accurate tissue color assessment, wound evaluation, and specimen identification. High CRI reduces misread risk in clinical tasks.
02
Dental
Shade matching and enamel assessment require accurate color rendering. CRI 90+ is the minimum standard for serious clinical dentistry.
03
Grocery & Retail
Produce, meat, and packaged goods look more appealing under high-CRI light. Better color rendering drives purchase confidence.
04
Education & Office
Natural-quality light reduces visual fatigue over long occupancy periods. Students and staff sustain focus longer under a cleaner spectrum.
05
Design
Conveying the right colors to clients is imperative to managing expectations. Using a CRI that works closer to natural light means the most accurate results.
03 ⸺ OCULAR HEALTH AND HUMAN WELLBEING
The light people spend their days under should not be working against them.
Most people spend eight to twelve hours a day under artificial light.
Conventional LEDs are designed for efficiency, not for the biology of the people underneath them. The 450nm blue spike that enables standard white LED output is the same wavelength range most implicated in retinal phototoxicity, digital eye strain, melatonin suppression, and circadian disruption. CleanWhite Pure removes it entirely.
Blue light hazard
The IEC 62471 blue light hazard function (B(λ)) peaks at 435–450nm. Removing the 450nm pump eliminates that peak. For clinics, schools, and gyms, that means less cumulative ocular exposure over the fixture’s life. It’s why CleanWhite Pure earns RG 0 while conventional LEDs score RG 1 or higher.
Visual comfort
The IEC 62471 blue light hazard function (B(λ)) peaks at 435–450nm. Removing the 450nm pump eliminates that peak. For clinics, schools, and gyms, that means less cumulative ocular exposure over the fixture’s life. It’s why CleanWhite Pure earns RG 0 while conventional LEDs score RG 1 or higher.
Circadian neutrality
The IEC 62471 blue light hazard function (B(λ)) peaks at 435–450nm. Removing the 450nm pump eliminates that peak. For clinics, schools, and gyms, that means less cumulative ocular exposure over the fixture’s life. It’s why CleanWhite Pure earns RG 0 while conventional LEDs score RG 1 or higher.
Long-term exposure
The IEC 62471 blue light hazard function (B(λ)) peaks at 435–450nm. Removing the 450nm pump eliminates that peak. For clinics, schools, and gyms, that means less cumulative ocular exposure over the fixture’s life. It’s why CleanWhite Pure earns RG 0 while conventional LEDs score RG 1 or higher.

04 ⸺ SPECTRAL POSITION, WHERE 405NM SITS
The only wavelength that disinfects without touching the circadian system.
The visible spectrum is not uniform in its effects on human biology. Different wavelength bands interact differently with the eye, the circadian system, and microbial chemistry. CleanWhite Pure’s 405nm anchor sits in a precise position: above UV, below the blue-light hazard window, and below the melanopsin curve—while remaining in the only visible wavelength range with proven antimicrobial activity.

2002. Melanopsin peak ~480nm; sensitivity declines sharply below 450nm.
05 ⸺ And one more thing
The same chip that lights better also continuously disinfects.
The 405nm wavelength that gives CleanWhite Pure its clean spectrum and superior color rendering is also the only visible wavelength with peer-reviewed, demonstrated antimicrobial efficacy. It is not a separate function. The same chip delivers both benefits every hour the light is on.
How it works
Photoinactivation: no UV, no chemicals, no mode switching.
405nm photons are absorbed by naturally occurring porphyrins within bacteria, fungi, and enveloped viruses. This creates reactive oxygen species, including superoxide, singlet oxygen, and hydroxyl radicals, which cause irreversible oxidative damage to the pathogen’s cell membrane, proteins, and DNA. The pathogen is destroyed from within. No added agent. No UV. No downtime.
Continuous, no cycles, no downtime.
As long as the light is on, the space is being treated. No scheduling, no evacuation, no staff involvement required.
Safe for fully occupied spaces.
IEC 62471 RG 0 means the disinfection function operates in ORs, patient rooms, classrooms, and gyms, with people present, without restriction.
Not a replacement for UV-C.
405nm visible light disinfection provides continuous passive reduction, not terminal sterilization. For high-risk terminal events, UV-C or chemical protocols remain appropriate.
No resistance development.
Photoinactivation targets multiple cellular systems simultaneously. Unlike antibiotics or chemical disinfectants, pathogens cannot develop resistance to oxidative ROS damage.
Questions about the spectrum.
Conventional white LEDs use a blue pump wavelength, typically around 450nm, which remains present whenever the fixture is on. This blue light is linked to blue light hazards, melatonin suppression, circadian disruption, and visual discomfort.
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.
