    Fight against viruses and bacteria

    UV-C lighting has the power to treat air, surfaces and water

    The quality of the air we breathe and the cleanliness of the surfaces we touch have a profound effect on our health and wellbeing. We’re all at risk of contracting and spreading viruses and bacteria, especially in busy public areas like the office, stores, schools and museums. A proven and effective way to treat a virus is through UV-C radiation. In laboratory testing, Signify’s UV-C light sources reduced SARS-CoV-2 virus infectivity on a surface to below detectable levels in as few as 9 seconds.1

    Ultimate protection for air, surfaces and water

    Treating air, surfaces and water

     

    We offer an extensive range of Philips UV-C lamps that can be integrated into luminaires and equipment of all sizes to treat air and surfaces. We have a proven track record of developing innovative UV-C solutions that are optimized for the application and work closely with manufacturers on design-in.

    Treating objects

     

    We also offer a range of Once BioShift® UV-C chambers for treating equipment. Resembling an industrial microwave, objects that do not qualify as medical devices can be placed in the chamber for speedy treatment, so they can be reused safely.4 The chamber treats a majority of viruses during the recommended 5-minute cycle.5

    Professional Services

     

    Our lighting application & design team will analyze with you in which type of areas you want to apply the UV-C solution. An audit on type of walls, materials used, fans, ventilation of these areas can be performed to define the dynamics of the room to ensure a maximum effect and application safety. Our UV-C lighting and system design will be made for these areas with the right UV light output, the right position, mounting height, angle and functionality of the UV-C devices.

    Trusted


    35 years experience in UV-C lighting and strong application expertise

    Effective


    All bacteria and viruses tested to date respond to UV-C treatment1,6.

    Fast


    Treats surfaces and objects in a matter of minutes.

    Versatile


    Can be used in numerous applications, such as offices, stores and schools.
    Used extensively by scientists for over 40 years2, UV-C is a know treatment for air, water and surfaces. All bacteria and viruses tested to date (many hundreds over the years, including various coronaviruses) respond to UV-C radiation.3 Signify has been at the forefront of UV technology for many years and has a proven track record of developing innovative UV-C products and applications.

    Applications

    Retail
     

    High-touch areas such as Point of Sale Keypads have a high risk of transmitting germs

    Work places

     

    Germs can be picked up from phones, keyboards and stationery

    Food services

     

    Germs and bacteria are common in raw and wasted foods

    Restrooms

     

    One of the most common places to find harmful germs and bacteria

    A word of caution


    UV-C products present minimum risk when used by professionals who know how to use them. They must shield their eyes and skin to avoid light damage and severe injuries to the eyes and skin.

     

    At this moment, none of our UV-C products are certified or approved under any applicable laws as a medical device and as such, Signify and/or any of its group companies do not currently intend for them to be used as medical devices anywhere in the world.

     

    1) In laboratory testing, Signify’s UV-C light sources reduced SARS-CoV-2 virus infectivity on a surface to below detectable levels in as few as 9 seconds (Nadia Storm et al, Rapid and complete inactivation of SARS-CoV-2 by ultraviolet-C irradiation, 2020. Report available at https://www.nature.com/articles/s41598-020-79600-8). In this study, an exposure to an UV-C irradiance of 0.849 mW/cm2 for the duration of 9 seconds was applied, resulting in an UV-C dose of 7.64 mJ/cm2. Our UV-C surface disinfection products (fitted with our UV-C light sources) will achieve the same level of virus infectivity reduction as long as the same UV-C dose is achieved on each area of surface that is irradiated.

    3) Fluence (UV Dose) Required to Achieve Incremental Log Inactivation of Bacteria, Protozoa, Viruses and Algae Revised, updated and expanded by Adel Haji Malayeri, Madjid Mohseni, Bill Cairns and James R. Bolton. With earlier contributions by Gabriel Chevrefils (2006) and Eric Caron (2006) With peer review by Benoit Barbeau, Harold Wright (1999) and Karl G. Linden

    4) There is a limit to the amount of times certain objects (such as non-medical face masks) can be reused after disinfection with UV-C.

    6) Alkco’s wall mount and ceiling mount upper air UV-C luminaires were tested for SARS-CoV-2 in Innovative Bioanalysis Lab.  The wall-mounted luminaire achieved 99.9% reduction in 10 minutes and the ceiling mount luminaire achieved 92.6% reduction in 20 minutes.  The luminaires were also tested for Escherichia coli in Intertek Lab.  Both luminaires achieved 99.9% reduction in 45 minutes.
