UV rays and environmental disinfection

UV-C Rays = Reliable Technology

UV-C rays work mainly by destroying DNA or Rna inside bacteria, viruses and fungi.
UV-C light has been used for decades to disinfect industrial surfaces and sanitize
drinking water and is, in fact, particularly advantageous for sanitary use because it
eliminates microorganisms such as the bacterium Clostridium difficile, one of the
main sources of nosocomial infections .
UV-C technology has been used for the disinfection of air, water and tools for over a
century. It is therefore validated by history. In fact, as early as the 1930s, UV rays
were commonly used for the treatment of air and water in hospitals and, starting
from the Second World War, they were widely used in processing centers, in water treatment plants and in any facility that had to do with microbial contamination.

Light Progress, since 1987, uses UV-C rays as a solution for microbial decontamination, a technology that over the years has been recognized as synonymous with efficacy and safety.

Remember to avoid exposure to the light emitted by the ultraviolet lamp in order not to risk:

• serious damage to the eyes and skin.

• to yellow plastic or painted surfaces.

Why is room disinfection important?

Environments play a significant role in disease transmission.

The latest tests carried out on the resistance of Sars-Cov-2 in different surfaces (steel, copper, cardboard, plastic) lead us to think that more attention should be paid to deep environmental disinfection, in any area, not just the hospital one.

New materials and new technologies are now being introduced in an attempt to reduce the environmental pathway of disease transmission. Ultraviolet disinfection of surfaces is proving to be one of the most decisive and easy to manage among the solutions on the market.

The use of UV rays is not intended as a substitute for normal manual cleaning activities, but as a physical and ecological alternative that allows for deeper disinfection. In combination with traditional methods it can make a substantial difference in contamination control.

Cleaning, Disinfection, Sanitization and Sterilization


Removal of dirt from a surface compatible with its correct conservation. There is no guarantee of safety with respect to viruses, fungi and bacteria.


Application of disinfectants, almost always of a chemical or physical nature (such as UV) which are capable of reducing, through destruction inactivation, the microbiological load present on objects and surfaces to be treated.


Intervention, based on the use of detergent chemicals, aimed at eliminating the contaminants that regular cleaning is unable to remove.


Total elimination of all forms of life. It occurs through particular processes, such as the use of saturated steam under pressure, fire or treatment at high temperatures.

If correctly used, UV rays can lead to abatement results close to sterilization, even if it is more correct to always speak of disinfection or high degree of disinfection.

Are UV rays effective and reliable for disinfection?

Absolutely yes: a correct use of UV rays allows the elimination of up to 99.999% of microorganisms, such as bacteria and viruses, with extreme simplicity and practicality.

Lately their popularity has increased as they disinfect practically all surfaces of a room with minimal effort and without the use of hazardous chemicals or gases. After carrying out the treatment cycle necessary for disinfection, the rooms are immediately reusable in absolute safety and without any precaution as the UV rays do not leave any residue or substances circulating in the air and on the surfaces.

What organizations recommend the use of UV-C rays?

Many world-class bodies and organizations such as WHO, EPA, CDC, ASHRAE have been recommending the use of UV-C rays for the disinfection of water, environments and air conditioning systems for decades. The use of UV-C rays is also indicated for the prevention of Coronavirus Sars-Cov-2 and, following the recent COVID-19 pandemic, it has been successfully introduced in widely affected countries such as China, with examples that include hospitals, urban transport or even domestic environments.

What are the areas of use for UV rays?

There are no limits to the possible applications of UV-C rays, however specific skills are required to use this technology in an adequate way, obtaining maximum results. UV rays are used every day at:


To disinfect air and surfaces production environments, disinfect the containers of products (packaging), isolate “protected” areas for the production and the product packaging, like the clean rooms, from areas at risk of contamination. Interventions of this type increase significantly security and conservation of the products we buy commonly.


To avoid the transmission of dangerous bacteria or viruses that may be present in the air or transported by contact by patients or visitors, such as the TB, Legionella, Sars and the new Covid-19. The sanitary field is historically the one with the most application examples, from air treatment to that of surfaces.


To avoid the transmission of any partogen into the air, but also to prevent the formation of mold and bacterial colonies inside the air treatment plants in the pipes. Air conditioning is responsible for “building-related diseases”, allergic alveolitis, virus and fungus infections, bronchial asthma, humidifier fever, legionellosis, etc. Many armies have UV-C systems to also prevent possible attacks biological (anthrax).


To eliminate all microorganisms that may be present in the water from wells and cisterns. UV rays are traditionally used in most public aqueducts and are often mandatory after an activated carbon filter in water dispensers that are increasingly taking hold in cities to replace the use of bottled water.


To avoid the formation of mold on the walls, to remove mites, to keep the air healthy inside a room, to treat water. UV-C rays also manage to eliminate odors and grease deposits in industrial kitchens and are also used in catering, with the support of ozone emissions.

If correctly used, UV rays can lead to abatement results close to sterilization, even if it is more correct to always speak of disinfection or high degree of disinfection.

Which microorganisms can be eliminated with UV rays?

Each microorganism has its own particular resistance to UV rays. For a high-level killing of a microbial load, for some myrcorganisms a few seconds of irradiation are sufficient while for others it takes longer or, for the same time, greater UV power. The charge reduction is expressed as “Log Reduction”, 1 Log = 90% reduction, 2 Log = 99% 3 Log = 99.9% etc.

These just introduced are the essential factors to understand and use UV technology effectively:

  • Objective of the degree of reduction (Log Reduction)
  • UV dose necessary for the elimination of the target pathogen
  • UV power in play
  • Exposition time
  • Space (Geometry and Distance)

What is the UV dose?

UV rays are effective against any microorganism. Thanks to experimental tests, it has been possible over the decades to establish the resistance to UV radiation of each pathogen. The energy needed to eliminate every single bacterium, spore virus, fungus, mold, etc. it is called dose and is expressed as instantaneous energy necessary to eliminate 99% (or 99.9% or 99.99% …) of the single strain.

Are UV rays effective against Coronavirus SARS-CoV-2?

Specific tests on the UV resistance of Coronavirus Sars-Cov-2 will be available soon. However, there are examples of scientific literature about the UV-C treatment of very similar viruses, such as that of Sars-1 or Mers. There is also evidence of the effectiveness of ultraviolet rays in the disinfection of air and surfaces from microorganisms much more complex and difficult to eliminate than this virus, such as C. Difficile, MRSA, or even more deadly threats, such as Ebola and Legionella. It is estimated that the Sars-Cov-2 virus can survive on surfaces for up to nine days, based on its similarity to Sars and Mers.

Standard disinfectants are effective against Sars-Cov-2, but to provide additional protection and defend against errors in the manual disinfection process, ultraviolet light can be used to disinfect surfaces and equipment following manual disinfection. UV technology is therefore a valid tool in the fight against H1N1, Sars, Mers and now also Covid-19.

Light Progress products for environmental disinfection

What are the advantages of Light Progress products for environmental disinfection?


Our UV systems can be switched on continuously in the absence of people (e.g. during the night or during work breaks.) The disinfection of air, machinery and all that which is contained within the environment allows to start the working day in ideal hygienic condition. The microbial load level of a room is therefore kept constantly low.


Purification or the integration of UV technology within the conditioning channels in centralized systems allows you to treat the air of an environment, 24 hours a day, without contraindications for the staff present.  A real “washing” of the air is thus obtained, lowering the microbial residue after a few minutes, until it is reduced to negligible percentages, in a simple, immediate and safe way and without the slightest contraindication.


For effective treatment (99.9% killing of bacteria) takes just a few minutes. All our products are sized in such a way as to guarantee safe results in certain and rapid times. After the treatment, the objects are immediately reusable, the rooms do not need to be ventilated, the surfaces have no residue.


With the special UVLON protection, the original and unique optional solution of Light Progress. No danger of dispersion of glass fragments from a possible breakage of the UV-C lamps.



The treatment is immediate and ready for use. Maintenance is minimal with low costs of both energy and service consumption. UV rays do not pass through the materials and are very safe when used correctly. For example, the UV-C wavelength (invisible) cannot pass through any glass, even if the traditional “blue light” of the lit lamp remains visible.

If correctly used, UV rays can lead to abatement results close to sterilization, even if it is more correct to always speak of disinfection or high degree of disinfection.

Direct irradiation in the absence of people



It can be easily applied as a common ceiling light, super flexible, versatile and simple to apply.

The UV-STICK series includes a wide range of models of direct irradiation strips, different according to the UV-C powers of the lamp (s) and the material of the case.

The -NX model is in fact in AISI 304 stainless steel; -AL model is made of high quality extruded aluminum, light and solid.

Placed behind the lamp a layer of reflective aluminum mirror bright mirrors the UV rays that are directed towards the surfaces to be treated by optimizing the angle of radiation by increasing the disinfection performance.

Tin to dust and water (IP 55).


Especially in the case of installation of multiple appliances, UV-STICK can be managed by controlling the operation of switching on, off, security control of entry into the treated room, fault alarm and hour counter.

It is ready for use and requires no special maintenance, except for the periodic replacement of the lamps. It is built entirely in Italy, with high quality and extremely resistant materials.

Air purifiers in the presence of people


UV-FAN is an extremely versatile UV-C air purifier and consists of a load-bearing structure in extruded aluminum and a front cover with micro-holes that allow the entry and exit of the air at the two ends. Conveyed by a silent integrated fan, the air present in the room enters the germicidal chamber of the purifier to be decontaminated by microbes, viruses but also chemical contaminants.

The germicidal chamber houses the UV-C lamps and is built in a special ultra-pure mirror aluminum which amplifies the disinfectant power of the lamps; by passing through it, the air is purified by all microorganisms to be returned to the environment free of contaminants.

Inside the chamber is housed the TIOX®, nano-structured titanium dioxide filter, which in combination with the very high UVC power emitted by the lamps, is an excellent photocatalyst that degrades organic and inorganic pollutants (SOV, VOC volatile organic compounds and NOX, nitrogen oxides) present in the environments.

In addition, the nano particles of TIOX® have a strong oxidizing power and amplify the germicidal effect of UV-C rays on microorganisms.


It can be used, always, even in the presence of people, thanks to the optical labyrinths that hold the UV-Cal rays inside, the silent fan and its low consumption. The possibility of constantly keeping the UV-FAN in operation, even 24h / 24, allows a real “washing” of the air, progressively lowering the microbial residue in the air after a few minutes, until it is reduced to negligible percentages.

The UV-FAN series includes a wide range of wall or wheel purifiers (-ST model), different according to the UV-C powers of the lamps and the dimensions.

Air Treatment



It is a disinfection system for HVAC that adapts to small spaces, even for retrofit applications installed inside the air conditioning ducts, or in the final sections of the Air Treatment Units (U.T.A.) directly from the outside. It creates a UV-C barrier that inhibits the proliferation of viruses, bacteria, molds, spores, very harmful to health, which commonly nest within the Air Conditioning.

It manages to treat the air flow that passes through its lamps, eliminating the bacterial load and the dispersion and distribution of dangerous and annoying pathogens in buildings. It inhibits the creation of biofilm on internal surfaces, the result of the presence of microorganisms and conditions favorable to their proliferation present in AC systems, such as temperature changes, high levels of humidity and darkness.

The increase in indoor air quality allows a consequent and general improvement in comfort but, more specifically, the use of UV-DUCT-FL eliminates important problems (such as Legionellosis, Tuberculosis, Influenza, etc.) but also as ” Sick Building Syndrome “,” Monday Fever “, promotes the control of high hygiene standards in the Food Industries and, in the health sector, that of dangerous Infections Related to Assistance (ICA).

In addition to the numerous health benefits, the use of UV-DUCT-FL allows important benefits in terms of running costs of the A.C. system, which is sanitized and remains clean without the need for continuous and expensive maintenance.

The UV-DUCT-FL series includes a series of flange modules from which two “U” lamps of different lengths (from 20 to 50 cm) and powers (from 70 to 90 W) emerge, protected by a stainless steel grid. The main features of UV-DUCT-FL are the super compact measurements and onboard controls, which allow an effective application even in existing air conditioning systems (retrofits).

It is installed by making two holes at the point of the A.C. channel, using the practical template provided. After inserting the lamps in these holes, it is only necessary to screw the flange directly to the duct, press the switch and you’re done. Specific ballasts are inserted directly inside the case to power the UV-C Light Progress lamps, optimizing their performance and durability.
