How the Spectral Blue system works
System overview
The Spectral Blue™ surface disinfection system consists of three parts:
- Spectral Blue disinfection devices.
- Optional - Control automation that switches between regular lighting and disinfection mode automatically.
- Optional - Photocatalytic coating.
The disinfection devices provide the disinfecting MWHI blue light that eliminates pathogens from the room air and surfaces.
The control automation is optional, and means any switches, presence detectors and timers that you may use for controlling the device activity during the day. Most devices are DALI-equipped, allowing smart and flexible configuration. Alternatively you can just have regular on/off switches or devices with a wall plug. Ideally your system is in blue light mode whenever the room is unoccupied and in general white light mode at other times.
The photocatalytic coating is an invisible, antimicrobial and dirt-repellent surface coating, that improves the antimicrobial performance of the system. With the coating the Spectral Blue system can eliminate pathogens in already 15-30 minutes (up to 99% reduction). The coating is based on nanotechnology and does not change the appearance of your premises.
Continuous disinfection - Blue light keeps facilities hygienic 24/7, not just once per day

Antimicrobial effect of the Spectral Blue system
The ability of blue light to destroy microbes is based on its ability to energize naturally light-sensitive compounds inside microbial cells.
When exposed to certain blue wavelengths and high enough intensity, these compounds start reacting, producing reactive oxygen radicals. These radicals, called Reactive oxygen species (ROS), are molecules containing very reactive oxygen. The ROS cause damage to the microbial cell's vital structures and destroys the cell internally.
Identified oxygen radicals are:
- O2- superoxide (type I reactions)
- H2O2 hydrogen peroxide (type I reactions)
- •OH hydroxyl radical (type I reactions)
- 1O2 singlet oxygen (type II reactions)
The efficiency of blue light can be further enhanced by applying the Spectral Blue photocatalytic coating on surfaces. The coating utilizes a phenomenon known as photocatalysis: energy of blue light starts a chemical reaction on the surface, producing short-lived Reactive Oxygen Species (ROS). The ROS disintegrate all microbes, including viruses, on the surface.
