The Power of UVC Light

UVC is a known disinfectant for air, water, and nonporous surfaces.
UVC radiation has effectively been used for decades to reduce the spread of viruses and bacteria, for this reason, UVC lamps are often called “germicidal” lamps. In the 1930s and 40s, an experiment in public schools in Philadelphia showed that upper-room ultraviolet fixtures could significantly reduce the transmission of measles among students. In the late 80’s it is used to combat tuberculosis and in the latter part, HAI’s or Hospital Acquired Infections.
UV-C equipped air disinfectants are designed to use short-wave ultraviolet light to inactivate the DNA of airborne pathogens and micro-organisms like viruses, bacteria, and fungi. On the market, UVC air disinfectants are currently sold as systems installed into pre-existing residential or commercial HVAC and re-circulating units. As air is forced through the device, it passes thru the UVC lamps, which directly disinfect the air by means of (UVGI) ultraviolet germicidal irradiation. UV Air Disinfectants are known to work better than normal particle filter purifiers when it comes to nasal allergic reaction and asthma prevention.

Signify, the world leader in lighting, together with the National Emerging Infectious Diseases Laboratories (NEIDL) at Boston University in the US have conducted research that validates the effectiveness of Signify’s UV-C light sources on the inactivation of SARS-CoV-2, the virus that causes COVID-19.

Since the start of the SARS CoV-2 pandemic, Dr Anthony Griffiths, Associate Professor of Microbiology at Boston University School of Medicine and his team have been working on developing tools to support scientific advancement in this field. During their research, they have treated inoculated material with different doses of UV-C radiation coming from a Signify light source and assessed the inactivation capacity under various conditions. The team applied a dose of 5mJ/cm2, resulting in a reduction of the SARS-CoV-2 virus of 99% in 6 seconds. Based on the data, it was determined that a dose of 22mJ/cm2 will result in a reduction of 99.9999% in 25 seconds.
“Our test results show that above a specific dose of UV-C radiation, viruses were completely inactivated: in a matter of seconds we could no longer detect any virus.
We’re very excited about these findings and hope that this will accelerate the development of products that can help limit the spread of COVID-19,” Dr Griffiths added.
Signify is the leader in UV-C light sources and has been at the forefront of UV technology for more than 35 years. It has a proven track record of innovation in UV-C lighting, which is designed, manufactured, and installed in line with the highest safety standards.
Eric Rondolat (CEO of Signify): “I’m very happy about the fruitful cooperation with Boston University in the fight against the coronavirus. Boston University has validated the effectiveness of our light sources as a preventive measure for companies and institutions as they seek ways to provide virus-free environments. READ MORE


In a press release on January 18, 2022. Signify the world leader in lighting, is equipping a significant number of schools in Munich with 7,500 Philips UVC air disinfection devices, providing schoolchildren, teachers and other staff with an additional layer of protection against viruses and germs. The closed air units provide continuous disinfection of the indoor air, while their unobtrusive design and silent disinfection make them ideal to use while classes are in session. READ MORE

The Company

The team behind LumenAire consist of R&D scientist and engineers engaged by ARID Indoor Air Solutions started its first research and development meeting in February 2020 during the onset of the COVID-19 pandemic. The aim is to combat the spread of the novel coronavirus thru improved indoor air quality using innovative, affordable and stylish solutions to air disinfection. The project was rolled out and funded by ARID Indoor Air Solutions Pte Ltd (Formerly ARID Builders Pte Ltd) under the leadership of its founder and CEO, Mr. James Paul Pilande.

The first product, the Pendant Light Purifier (PLP) conceptual model was completed on 24th March and was applied for a patent on 31st March 2020. The team worked despite the circuit breaker period and the full working prototype was completed on the 5th of June. Further improvements were added and product testing under TUV-SUD PSB Pte Ltd started on the 28th of September 2020.

At the end of December, the first batch of products was completed for local and overseas roll-out. It has been shipped to Hong Kong, India, Malaysia, Dubai, Saudi Arabia, and the Philippines at the start of January 2021.


The LumenAire™ has been selected as the Top-6 finalist representing Singapore out of 270 participants worldwide in the recently concluded CapitaLand Sustainability X Challenge. READ MORE or WATCH the PITCH
