The Power of UVC Light

Germicidal UV light has been used in the treatment of tuberculosis and to disinfect hospitals, kitchens, meat processing plants, and laboratories. UV air disinfectants are designed to use short-wave ultraviolet light (UVC light) to inactivate airborne pathogens and micro-organisms like molds, bacteria, and viruses. They have the same goal as that of other air purifiers which are to reduce indoor air pollutants.
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.

The LumenAireDifference

Singapore has been at the forefront of the ASEAN region’s fight against COVID-19. So far the country has been the most successful in containing the spread of the coronavirus. The Singapore government has been actively involved with research and tertiary institutions as well as funding businesses thru Enterprise Singapore to develop new technologies to keep the pandemic under control.  LumenAire™ thru its parent company ARID Indoor Air Solutions Pte Ltd has been selected as one of the key air disinfection devices to fight COVID-19, the company has been working with reputable research institutions to prove its effectiveness and maintain its efficacy against any strain of the coronavirus.  

The LumenAire™ Air Disinfection Fixture performs better than the traditional way of integrating UVC light into an HVAC system. It pushes contaminated air to thru the lighting fixtures integrated germicidal irradiation chamber equipped with a HEPA filter and Activated Carbon fabric, coupled with an Ozone-free 253.7nm UV-C lamp efficiently killing 99.9% of harmful viruses in seconds before releasing the disinfected air back to the atmosphere. This method is repeated overtime and the multi-pass circulation ensures that a steady flow of clean air is always present in an indoor environment.

The LumenAire™ is also known to work well in eliminating TVOC & Odour, therefore performs better than particle filter-based air purifiers in preventing nasal allergic reaction and asthma.

 Philips / Signify Research on SARS-CoV2

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. 

“Given the potential of the technology to aid the fight against the coronavirus, Signify will not keep the technology for its exclusive use but make it available to other lighting companies. To service the growing need for disinfection we will increase our production capacity multifold in the coming months. READ MORE

UVC Light vs Coronavirus causing COVID-19

Ultraviolet light can be an effective measure for decontaminating surfaces that may be contaminated by the SARS-CoV-2 virus by inducing photo dimmers in the genomes of microorganisms. Ultraviolet light has been demonstrated to be capable of destroying viruses, bacteria, and fungi in hundreds of laboratory studies. The SARS-CoV-2 virus has been specifically tested in Boston University (NEIDL) for its ultraviolet susceptibility, many other tests on related coronaviruses, including the SARS coronavirus, have concluded that they are highly susceptible to ultraviolet inactivation.
The novel coronavirus is a kind of positive-sense single-stranded RNA virus, same as the SARS and MERS virus. Researches on SARS found out that like any other virus, this kind of coronavirus is also sensitive to heat radiation and UVC light. It can be diminished when exposed to UVC irradiation stronger than 90 μW/cm2. Thus, in theory, UV light would be able to destroy the novel coronavirus SARS-CoV-2. In Wuhan, China it has been used to disinfect banknotes that have been stored for 7-14 days before releasing it back to the public.
In the United States, it has been widely used in Hospitals and Healthcare facilities to avoid the spread of the virus through aerosol and help prevent Hospital Acquired Infections (HAI).

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 on 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
