Finelite Expands Indigo-Clean Offering with Dual-Mode Technology

Indigo-Clean Dual-Mode Technology

A Continuous Environmental Disinfection System Scientifically proven to Kill 94% of SARS-CoV-2*


(Union City, CA) January, 2022 – Finelite, Inc., a leader in energy-efficient lighting for offices, healthcare, and educational facilities, is pleased to announce that Finelite has integrated Kenall Manufacturing’s Dual-Mode Indigo-Clean Technology into their popular HP-2, HP-4, HP-6, and HPR product portfolios.

Aaron Smith – VP of Technology and R&D at Finelite stated, “We are excited to expand our portfolio of disinfection lighting solutions with the new addition of Dual-Mode Indigo-Clean. This addition will give our customers the ability to create cleaner environments more efficiently. This is a critical moment where we can add a tremendous amount of value and confidence to our customers.”

Indigo-Clean is a lighting technology that lights the space and also provides continuous environmental disinfection using visible light technology. This technology has been proven effective with available published research conducted by Icahn School of Medicine Mount Sinai to kill bacteria, Influenza-A, and SARS-CoV-2* – the virus that causes COVID-19. When the light is on, disinfection is active. Indigo-Clean Technology contains no UV and is certified safe for room occupants and materials.

Dual-Mode Indigo-Clean Technology utilizes a two circuit board design. When the space is occupied it utilizes a combination of blended white LEDs and 405nm LEDs. When the space is unoccupied, it utilizes just the 405nm LEDs with increased output to increase disinfection efficacy. Dual-Mode switches between occupied and unoccupied via automated controls, such as occupancy sensors and timeclocks.

In May 2021, Finelite introduced Single-Mode Indigo-Clean Technology which employs an occupant safe, blended white + 405nm visible light, exclusively, to disinfect the space.

Finelite will immediately be offering Dual-Mode Indigo-Clean Technology in a variety of color temperatures; ideal for Healthcare, Commercial, Education, Retail, Transportation and other applications where people congregate.

Finelite and Kenall are part of Legrand North and Central America’s lighting sector and are leading manufacturers of specialized solid-state lighting solutions and controls.
