Indigo-Clean Technology
The path to managing COVID just got a whole lot brighter

Safe, Continuous, Game-Changing Disinfection

What if the lighting used throughout your facility came with the added benefit of fighting germs? Unlike UV lighting solutions, Indigo-Clean technology is safe, continuous, and effective at killing SARS-CoV-2*, Influenza-A*, Staph Aureus** and a list of pathogens that negatively impact health and wellness.

A word on Safety

What do we mean by safe? Exposure to UV disinfection can be harmful. However, because Indigo-Clean technology uses the visible light spectrum, it is always safe for room occupants–even when performing at the highest level of disinfection. Which means no room downtime, and no worries about safety.


Destroy 94% of SARS-CoV-2

Patients, students, shoppers, guests, employees, building staff, you name it–they’re all safe on our watch. Indigo-Clean technology functions effectively even while people are present, providing safe, continuous germ-fighting performance UV can’t touch.








No matter where you go, Indigo-Clean technology is trusted to keep spaces clean, and people safe.

Proven to kill pathogens, cut costs, and add value

For more than 7 years, Legrand’s patented lighting technology has been effectively used by hundreds of hospitals and healthcare systems to reduce harmful bacteria, such as Staph, including MRSA, in ORs and patient spaces. Indigo-Clean has also demonstrated a reduction in intraoperative transmission and surgical site infections in studies at Maury Regional Medical Center and the University of Iowa. Most recently, it has been proven highly effective in killing viruses; expanding its use far beyond healthcare settings.


Eliminating a range of pathogens

Killing pathogens in the air, and on surfaces

Using a patented blend of 405 nanometer indigo and white LED, Indigo-Clean bathes spaces in germ-fighting protection. Unlike UV, Indigo-Clean light technology is both direct and indirect. Reflecting off walls and other surfaces, it reaches the many shadowed areas UV light can’t. Once exposed, pathogens are oxidized from within, no matter where they exist: in the air and on surfaces.


Around-the-clock environmental disinfection.

Around-the-clock environmental disinfection

Rather than relying solely on staff to clean surfaces, or HVAC systems to purify the air, Indigo-Clean combines the benefits of both. While patients and doctors may not notice it, our technology is always working; reducing bioburden between cleanings, and continuously filling the disinfection gap left by episodic (or non-continuous) cleaning methods.

Designed to address your entire facility, from ORs and areas where the risk of infection is highest, to classrooms, conference rooms, waiting rooms, and other high-traffic spaces, Indigo-Clean technology is a safe and fundamental part of any disinfection strategy.
