Original Press Release:

New Indigo-Clean® M4DLIC6 Downlight Provides Proven Visible Light Disinfection for Surgical Suites

Indigo-Clean introduces a new, dual-mode 405nm downlight to complement the popular Indigo-Clean M4SEDIC luminaire.

KENOSHA, WIS. (PRWEB) APRIL 29, 2019 - Indigo-Clean is now making it even easier to install visible light disinfection fixtures in surgical suites and other critical healthcare environments. The brand has debuted a new, dual-mode 405nm downlight to complement the popular Indigo-Clean M4SEDIC luminaire.

The new M4DLIC6 downlight switches automatically from a blended white mode that provides ambient light and disinfection while the room when occupied, to full Indigo mode for maximum disinfection when the room is empty. It is part of a family of lights engineered to safely support the patient, care team and the hospital environment by killing harmful bacteria, including staph such as MRSA - the luminaire is also sealed to prevent the spread of infection.

Cliff Yahnke, PhD, Director of Clinical Affairs at Indigo-Clean, said, “The new MDLIC6 will provide additional disinfection power with a nominal footprint, which can be critical in the surgical space. We are very excited to continue growing the product line and offer additional visible light disinfection solutions.”

Indigo-Clean fixtures use light-emitting diodes (LEDs) to generate visible white light that also contains a narrow spectrum of indigo colored light (405 nm). This wavelength automatically, safely and continuously disinfects the air, and hard and soft surfaces. When the OR is not in use, the lights switch automatically to an Indigo-only mode, which provides a higher degree of safe disinfection.

Indigo-Clean bolsters current disinfecting efforts to reduce harmful bacteria in the environment. A recent peer-reviewed study conducted at Maury Regional Medical Center in Columbia, Tennessee, demonstrated a 73% reduction in surgical site infections (SSIs) in the test room compared to the baseline period. Preventing even a single SSI, which can increase healthcare costs by more than $25,000 per infection, provides healthcare facilities with an immediate return on their Indigo-Clean investment.
