All UV-C solutions are specified with appropriate safeguards, whether fully housed within a safe unit (Portable air disinfection), mounted at optimum height in a space (Upper air disinfection) or with automatic cut out switch (Chamber object disinfection), to ensure they can be operated safely.
Our product options include: UV-C disinfection portable air unit, upper air ceiling mounted, upper air wall mounted and stand alone object disinfection chambers.
UV-C TECHNOLOGY EXPLAINED
UV-C radiation is a proven disinfectant for air, surfaces and objects and when applied safely and effectively can help reduce the risk of the spread of infection through bacteria and viruses.
UV light is composed of UV-A, UV-B and UV-C and is invisible to the human eye. UV-C light is helpful as it is extremely effective in breaking down the DNA and RNA of micro-organisms, so that they cannot replicate and cause disease.2
UV-C has been used safely and effectively in specialist settings for over 40 years3 and due to the continued development of this technology it can now be deployed to other settings, including offices, schools, hospitality and healthcare.
Marwood have over 60 years’ experience in specialist lighting solutions, and are Philips qualified UV-C specifiers and distributors, providing comprehensive advice on UV-C specific projects as well as building UV-C lighting solutions into broader lighting schemes.

UV-C FREQUENTLY ASKED QUESTIONS
Explore further detail below in answer to some of the most common questions about UV-C lighting solutions.
All bacteria and viruses tested to date (many hundreds over the years, including various coronaviruses) respond to UV-C disinfection.1 Therefore implementing UV-C disinfection technology can reduce the risk of spreading and contracting a whole range of viruses and bacteria.

As with all our products and services, safety is our first priority and when specified, installed and used correctly, the use of UV-C lighting for disinfection as part of a multi-disinfection strategy is perfectly safe.
It is important the solutions are appropriately considered according to the individual requirements of each setting, and our trained lighting specifiers are experienced at matching the right product with the right setting to ensure both optimal results and to provide complete reassurance around safety.
The UV-C elements within our stand alone products - including our portable air units and disinfection chambers - are housed within sealed units that ensure safe use at all times.
Our upper air and active air solutions are carefully specified and installed by our qualified installation team to deliver appropriate, bespoke specification and installation for your setting, ensuring they are safe to use.
The Marwood team ensure that all our UV-C products can be operated in line with the relevant safety standards. Further information on these standards is shown below:
|Applicable UV-C safety standards:
|IEC PAS 63313 + IS
All electrical devices must fulfil the electrical, thermal, mechanical, human exposure to electromagnetic fields (EMF) and photobiological safety requirements provided in International Electrotechnical Commission (IEC) standards and UV-C devices must additionally meet:
- the UV-C safety product standard IEC 60335-2-65 in case of “Closed” air purification devices with a forced airflow through the contained UVGI compartment in the device (like our Active-Air and UVCA200 devices).
- the UV-C safety specification IEC PAS 63313 in combination with the UV-C safety application standard ISO15858 in case of “Open” air disinfection devices which safely distribute the UVGI in the well-defined upper room area of the room (like our ceiling or wall-mounted upper room devices).
Other than that, the products are designed to meet the normal CE / UKCA product certification.
UV-C light disinfection has been used safely and effectively in specialist settings for over 40 years, so there is significant data to support the technology that now enables these benefits to be deployed in day to day settings.
UV-C light is helpful as it is extremely effective in breaking down the DNA and RNA of micro-organisms, so that they cannot replicate and cause disease.
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.
Our Philips UV-C disinfection upper air wall mount luminaires inactivated 99.99% of SARS-COV-2, the virus responsible for the COVID-19 disease, in the air of a room within 10 minutes. At 20 minutes, the virus was below detectable.2

UV-C can safely be used in most workplaces and public settings, including:
- Education: Nurseries, schools, colleges and Universities
- Retail: Shops, banks and food outlets
- Fitness and wellbeing: Hair and beauty salons, gyms and indoor sporting venues
- Hospitality: Restaurants and washrooms
- Sports and Events: Communal indoor spaces, bars, restaurants, venues.
- Travel: Airports, waiting spaces and vehicles
- Office: Offices and factories
Our UV-C lighting solutions are not certified or approved as a medical device, so should never be used as such and should therefore not be used in a clinical setting.
Carefully tailoring and matching the right UV-C lighting solution to your specific workplace is an important part of ensuring the safe, effective deployment of this technology.
In order to ensure this, Marwood will undertake a survey in person as required, or provide advice and guidance through the appropriate application. Certain physical characteristics of buildings, such as ceiling heights and room size and use, will naturally inform the specification of the correct product. For instance, the popular upper air UV-C lighting solution can only be installed in rooms with ceiling heights of around 2.4m or higher, however we have many alternative solutions that could work for your organisation. One of our experienced and qualified lighting specifiers will guide you on this.
UV-C lighting technology has been used safely in specialist settings for over 40 years and through a new, exciting range of products is now accessible to a broader range of organisations to take advantage of this technology and provide safer, cleaner environments for all users.
UV-C lighting technology works by significantly reducing the levels of microorganisms and viruses in the air and on surfaces, that impact workplaces and education settings, thus positively impacting the number of infections that are likely in these environments.
With all UV-C lighting installations, Marwood’s experienced team ensure appropriate specification and qualified fitting, meeting all required Health and Safety and regulatory standards.
This will depend upon the solution that is recommended. Our portable solutions are ‘plug and play’ so can simply be installed in the agreed location and put into use immediately, following the user guidelines provided with the unit.
Our upper air solutions will be installed for you by our approved installers, to ensure the application is applied exactly per the specification and can be signed off once installation is complete.
For object disinfection (Tablets, keys, shared devices), the chambers are ‘plug and play’ so can simply be installed in the agreed location and put into use immediately, following the user guidelines provided with the unit.
Our surface disinfection solutions will be installed for you by our approved installers, to ensure the UV-C products and controls are applied exactly per the specification and can be signed off once installation is complete.
Over time, it is possible that UV-C radiation may cause the photo-degradation of materials within the room, such as plastics, paints and textiles. This should therefore be considered as part of the installation process.
The maintainable element within the system are the UV-C lamps and filters. Philips UV-C solutions have a usable lamp and filter life of 9000 hours and are replaceable at end of life. Marwood can discuss a maintenance regime with you as we guide you through the process.
