Continuous Visible Light Disinfection Keeps Spaces Safer

In healthcare, a highly successful disinfection method is vital for critical environments. Ultraviolet-C (UV-C) radiation has become the most popular method because of its proven ability to dramatically reduce the transmission of many viral and bacterial infections, including mumps, measles, tuberculosis, and COVID-19. However, UV-C radiation poses a real danger to humans.

Indigo-Clean from SLD Technology

More and more life science facilities are choosing safer options. SLD Technology’s Indigo-Clean is used in place of UV-C radiation and is approved for human exposure. Using a safe 405-nanometer frequency of visible light, Indigo-Clean operates very close to the UV spectrum, referred to as near-UV. The continuous environmental disinfection technology uses an LED visible light that, like UV-C, can kill a wide variety of pathogens, including SARS-CoV-2 and Influenza, but can simultaneously provide safe illumination for the people in the room.

Two Operating Modes

Indigo-Clean has two operating modes: white and indigo blue. In white mode, white and 405nm LEDs are on simultaneously, so they operate at a lower dose. It continuously cleans 24 hours a day, seven days a week, 365 days a year. This mode is used during and between procedures to clean the room. When a deep cleaning is needed, it automatically turns to the indigo blue mode, which we call full dosing, when the space is unoccupied.

Third-Party Research Confirms Performance

According to an AJIC peer-reviewed study, Indigo-Clean has been shown to reduce harmful bacteria by 85%. This research reveals the potential to reduce healthcare providers’ costs and the additional cost per patient savings due to fewer healthcare-associated infections (HAIs).
