What is Indigo‐CleanTM?

  • An overhead light fixture which continuously and

safely disinfects the environment using visible light

2 Indigo‐Only Mixed‐White

White Disinfection Mode = Ambient White Light + Disinfection Indigo Disinfection Mode = Increased Disinfection Only

How Does Indigo‐Clean Work?

  • 3. Pathogen inactivation breaks the

environmental chain of infection

  • 4. Measured bacterial reduction*

  • 1. Continuous, automatic, safe system creates hostile

environment for bacteria

  • 2. Environment creates Reactive Oxygen Species

within bacteria causing inactivation

Types of Visible Light Disinfection

Indigo‐Only

  • Disinfection only

Mixed White

  • Use of complimentary colors

allows for ambient lighting applications

Clinical Implementation of Indigo‐ CleanTM

  • Overhead light fixtures which continuously and

safely disinfect the environment using visible light

10 Indigo‐Only Mixed White

Wall switch can be used to select desired mode OR Occupancy/ Vacancy control can automatically switch between modes

Significant reduction of total bacterial contamination

  • n surfaces around the room (2-day use)

76% reduction

86% reduction

All reductions in bacterial contamination were achieved over and above standard cleaning and infection control practices Whole Room Results Surface-Specific Results

Froedtert & The Medical College

  • f Wisconsin Froedtert Hospital
  • GI Diagnostic Waiting Area
  • Easier to show a reduction

due to high amount of bacteria

  • Proximity to procedure

rooms

  • Approximately 450 ft.2

(Equivalent to small OR)

  • Results consistent with

previously published patient room results

  • Additional studies underway

Clinical Results for Indigo‐CleanTM

  • Inactivation of S. aureus in Waiting Room

70%+ Decrease

“In Phase 2 of the trial, where the lighting deployment was optimized across the room, we were able to improve the bacterial reduction to more than 70%.” ‐ Dr. Nathan Ledeboer, Associate Professor of Pathology, Medical College of Wisconsin

Clinical and Commercial Success!

  • State‐of‐the‐art

facilities in Las Vegas and other unannounced locations

  • Henderson Hospital‐
