Indigo-Clean Technology
Environmental Disinfection Lighting

Indigo-Clean® Technology is a safe environmental disinfection light source integrated into Finelite luminaires. Proven through recently conducted independent laboratory testing, Indigo-Clean Technology kills bacteria, Influenza-A, and SARS-CoV-2* – the virus that causes COVID-19. The 405nm Indigo-Clean germicidal wavelength contains no ultraviolet (UV) and is safe for room occupants and materials.

How Does Indigo-Clean Technology Work?

Indigo-Clean Technology is a continuous environmental disinfection system that blends standard white LEDs and 405nm Indigo-Clean Technology LEDs. The narrow spectrum light provides a safe visible light that disinfects the space. When the light is on, disinfection is active.


  • Contains NO ultraviolet (UV) wavelength light

  • The 405nm light targets bacteria and produces intra-cellular Reactive Oxygen Species (ROS)

  • Similar to bleach, these ROS kill the bacteria and prevent it from re-populating the space

  • The 405nm light emitted reflects off walls and surfaces killing bacteria in the air and on surfaces


Indigo-Clean Technology Is Certified Safe

The Indigo-Clean Technology 405nm is visible light and safe for people and materials unlike all types of ultraviolet (UV) light. Indigo-Clean Technology is certified as 'risk exempt' (per IEC62471) eliminating the need for exposure controls, while still being clinically proven to improve patient outcomes.
