Q & A

Are the 222 UVC devices sold on this website TGA approved?

We have consulted with and sought the advice of the The Therapeutic Goods Administration (TGA) as well the Commonwealth Health Minister and both have confirmed that TGA approval and listing on the Australian Register of Therapeutic Goods (ARTG) is not required for our products.

Will 222 UVC device save me money?

Yes! 222 UVC devices are fully automatic and require no personal effort. Install, turn it on, forget. It's sanitation genie that works in the background for you, all day long, every day, and never calls in sick. 

  • It doesn't consume any chemicals or any cleaning products.
  • No sprays, mists or fog. 
  • No dampness.
  • No streaks. 
  • It doesn't produce waste.
  • It reduces the amount of time and money you spend on cleaning while delivering a substantially higher level of sanitation.  
  • It doesn't have any filters that require disposal to an EPA approved infectious waste facility. 

222 UVC devices will deliver an operational cost reduction by virtue of reducing cleaning labour and materials costs.

More importantly 222UVC device sanitises your workspace air as well as surface. 

This simultaneous dual capability and the ability to kill a wide variety of infectious microbes that are common in most work and public spaces, such as those that cause sore throats, cold and flu means big opex savings is achieved by reduced absenteeism due to less inter-staff transmission of workplace germs.  

Does 222 UVC Light kill infectious pathogens commonly found in public places?

Yes! 222 UVC light "kills" or more accurately inactivates a very large range of infectious pathogens, including bacteria, viruses and molds.

222 UVC is very effective against the pathogens that are widespread and commonly found in public place. These include;

  • Streptococcus pyogenes which is associated with causing sore throats.
  • Human Rhinoviruses which is associated with causing the common cold.
  • Influenza virus which is associated with causing the flu.
  • SARS-Cov-2 which is associated with causing Covid-19 illnesses.

Where should I install my 222 UVC devices?

222 UVC devices should be installed in locations where the light emitted from the device can land on surfaces that people touch frequently. These would include door handles, counter-tops, chairs, desks, keyboards, mice, and the like. 

Remember, all the airborne particles in the air space between the Far UVC light and your target surfaces will also be sanitised, therefore positioning the light to cover as many surfaces as possible is the key consideration when determining the install location. 

Each of our products it's own product information page which will indicate the surface area that the product will cover. Generally, the 150 Watt products will cover 55m2 and the 20 Watt products will cover 30m2.  To ensure optimum protection we recommend that you firstly take into account the best sanitation time for your setting and secondly use multiple lights to provide over-lapping coverage.

Please note, glass windows block-out 222 UVC light. As such consider it to be a the same as a wall, i.e. they both act as a barrier. 

Ideally for the lights located overhead, we recommend positioning them 2.1m to 2.5m above floor level.  In buildings having high ceilings or roofs our Pendant unit can be used and suspended via wires or chain. 

Where wall mounting is required, we recommend fitted them at a height of 1.6m to 1.8m above floor level.

What is 222 UVC light?

This is the region of the electromagnetic spectrum and part of the UV-C spectrum of radiation, from 107 to 222 nm, outside of visible light, which is safe for human eyes and skin.

What is 222 UVC radiation used for?

Since 222 UVC kills airborne viruses and does not harm humans, it is most effective when used in crowded places: buses, trains, airports, entrances to shopping centres, elevators, escalators and so many more.

What’s known about 222 UVC light and the new coronavirus?

UV-C radiation can be used to kill the new SARS-CoV-2 coronavirus. Because it can effectively inactivate the new coronavirus without the use of chemicals in the presence of people, Far-UVC radiation is a very attractive disinfection option.

Does 222 UVC light kill COVID 19?

222 UVC light kills all dangerous pathogens, not just covid 19, but all viruses, bacteria, and mould.

Where are 222 UVC lamps already used?

What are 222 UVC emitters?

Currently, there are two types of lamps that emit 222 UVC: excimer lamps and microplasma emitters.

What are Excimer lamps?

Excimer lamps or krypton-chlorine (KrCl) excimer lamps emit mainly far ultraviolet radiation with a maximum wavelength of 222 nm and are a safe alternative to low pressure mercury vapor arc lamps.

What is the difference between excimer lamps and mercury lamps?

Excimer lamps with a wavelength of 222 nm have exactly the same bactericidal properties as mercury discharge lamps, but shorter wavelengths of radiation do not penetrate the cells of the eyes and skin and cannot cause harm.
Excimer lamps can constantly work in the immediate vicinity of people in the room to disinfect air and surfaces.

How much safer is 222 UVC (222nm) compared to UV-C (254nm)?

222 UVC (222 nm) is nearly 1000 times safer than UV-C (254 nm). UV-C will begin to negatively affect the skin and eyes of a person with a radiation of more than 6 mJ / cm2, while 222 UVC at a radiation of 5000 mJ / cm2 does not cause any damage or even redness.

Which lamps last longer, excimer lamps or discharge lamps?

Excimer lamps do not use electrodes, which wear out over time and degrade the characteristics of the lamp, so an excimer lamp lasts 3-5 times longer than a gas discharge lamp, but this also depends on the lamp manufacturer.

Do Excimer lamps contain mercury?


What are microplasma emitters?

Microplasma emitters are based on the same technology previously used to produce plasma television screens, but emit ultraviolet light with a maximum wavelength of 222 nm.

Do Excimer lamps generate ozone?

No. 222 UVC uses lamps that do not emit light in the 185nm wavelength range that typically generates ozone for conventional UV-C lamps.

Are 222 UVC lamps safe for plants?

222 UVC lamps are safe for plants, on the contrary, they kill harmful microorganisms on their surface, improving growth, flowering and fruiting.

Are 222 UVC lamps safe for animals?

Far ultraviolet lamps are safe for animals. There are known cases of using Excimer lamps in poultry farms to prevent the spread of bird flu.

How to properly design an ultraviolet germicidal system?

To properly design a UV germicidal system, we need to know the intensity distribution of UV sources in the same way that we calculate the intensity distribution for luminaires. View example –

In what units is the intensity of ultraviolet radiation measured?

Intensity of ultraviolet radiation is expressed in microwatts (mW) per square centimeter (cm2) or in microjoules (mJ) per square centimeter (cm2) per second. One microjoule is equal to one microwatt per square centimeter per second.

How to choose the dose of radiation?

Studies have shown that complete deactivation of COVID-19 requires 1.7 mJ / cm2. Some researchers recommend ( ) using a dose of 2 mJ / cm2. The radiation dose depends on the number and power of ultraviolet sources and the distance and time of radiation.
