Mark Architectural Lighting Introduces SLOT 6 Recessed with Care222® Technology

January 3, 2023 Scott Bailey

SLOT 6 Recessed with Care222® technology reduces active pathogens* on non-porous surfaces and in the air using Ushio Care222® far-UVC disinfection** technology. SLOT 6 features a mercury-free far-UVC excimer lamp that contains a patented short pass filter for narrow band 222nm emission. This removes wavelengths that penetrate the living tissue in skin or deeper than the top layer of the cornea.

Blending modern aesthetics with unparalleled optical performance, the Slot 6 LED luminaire creates simple lines of light. Energy efficiency, design flexibility and seamless control make this recessed fixture a brilliant addition to any design. Available in 4’ or 8’ lengths, SLOT 6 can be used to create continuous runs that elevate ceilings in offices, lobbies, hotels and beyond. Slot 6 delivers up to 1200 lumens per foot at an excellent color quality of up to 90CRI.

Care222® technology uses filtered 222 nanometer UV-C light to inactivate a variety of bacteria and viruses* in spaces like conference rooms, break rooms and rest rooms. A patented short pass filter ensures only a narrow band of 222nm UV-C light is emitted, which does not penetrate living tissue in the skin or past tear layers in the eye.  SLOT 6 can be used in occupied spaces when properly installed and operated.
