Learn How UV Light Curing Improves Your Process

UV light curing is the process of altering the properties of polymers, or photopolymers which refers to polymers that undergo changes to their molecular structure when exposed to light.  UV light emits invisible electromagnetic radiation, causing a change in properties to photopolymers. UV light will cause a photopolymer, which are a wide variety of resins, to instantly dry, harden or seal with an unbreakable bond.

UV light is used in many curing processes worldwide by industrial, commercial and government manufacturing and production companies to improve their process.  By exposing their manufactured polymer products to UV radiation, they can instantly dry ink on parts and strengthen surfaces without using harmful chemicals or solvents.  Some examples of processes that benefit from UV curing include:

• Instantly drying of inks, lacquers and varnishes

• Creating an improved adhesive bond

• Enhancing decorative glazes

• Drying outer surface coatings

• Improving graphic designs

• Screen printing

• Disinfecting of surfaces, air, and water

• Disinfecting medical equipment

This is only a short list of the multitude of benefits realized by UV curing.  As more and more businesses realize the many benefits of curing with UV radiation, there will continue to be an increase in companies adopting this superior curing method in their processes.

Types of UV Light Curing Lamps

The three basic types of lamps used in UV curing processes are:

• Low-Pressure Amalgam Lamps

• Medium-pressure UV (MPUV) Lamps

• High-Pressure UV (HPUV) Lamps

Low pressure amalgam lamps are typically used for polymer curing, although they can also be highly effective in germicidal applications.  Medium Pressure lamps are effective in germicidal applications and are typically used for air, water, and surface disinfection, while high pressure lamps are typically used to alter the properties of photopolymers in many UV curing processes.

Benefits of UV Light Curing

There are a multitude of benefits to using UV lights for curing, some of the most important would be efficiency, consistency and safety.

Efficiency

There is no other method that is quite as efficient at curing products as using UV light.  Depending on your operation, you could utilize specific UV light curing machines for your process or use more of a conveyor type of UV curing station to instantly treat numerous parts, without even touching them.  Imagine the time, money and labor you save by having an instant curing process occurring simply while your parts are being transported from one station to another such as quality inspection or shipping. The alternative methods such as drying or using solvents are less desirable due to several factors.  Force drying or air-drying products leaves them susceptible to inconsistencies with evaporation and possible contamination, and takes more time than an instant UV cure.  In manufacturing, time is money, and anytime you can improve your cycle time with a higher level of quality, it is evident which method is preferred.   UV light curing dramatically improves throughput and cycle times, with less costs than additional labor and purchasing chemicals which could be harmful to employees and the environment.

Consistency

Consistency is key to producing high quality products.   UV curing produces a consistent process with an even amount of UV exposure applied to parts and products, whereas employees applying a chemical spray for an outer coating can produce inconsistencies in the finished product.  Allowing parts to air dry also leaves room for an inconsistent finished surface due to evaporation.  As all quality minded OEM’s are aware, consistency increases the quality of products in all processes.

Safety and Health of Employees

While efficiency and consistency are top considerations for any production process, the safety and health of your workforce is also a top consideration.  With UV curing there is no emission of harmful pollutants and chemicals in the air, and no need to purchase or store hazardous materials and maintain material safety data sheets on such materials.  Using ultraviolet radiation is effective on photopolymers, and safe to the environment and your workforce.  With all these benefits, it is no wonder that OEMs, quality and production managers are realizing the value of ultraviolet radiation to enhance their production processes.  Cost efficient and consistent processes dramatically increase throughput and profitability.  Combined with health and safety practices UV curing is the most desirable of processes used to cure product surfaces.

UV Light in HVAC Effectiveness

Originally posted at: https://www.light-sources.com/blog/uv-light-in-hvac-effectiveness/

Direct exposure to UVC lights can be hazardous to skin and eyes, although with the right type of germicidal lamps and proper installation, there is proven evidence of high germicidal UV light in HVAC effectiveness.

How Do UV Lights in HVAC Systems Work?

UVC lights are designed to emit particular wavelengths in the range of 254 nanometer (nm), which is effective at penetrating the DNA of microorganisms. The UV radiation is absorbed by the cells’ DNA which renders them unable to produce the needed proteins to survive or replicate. UV light does not immediately kill the germs, although it shortens their life span, and nullifies their ability to replicate and cause harm.

UVC light can penetrate the cells of viruses, bacteria, mold spores, fungi, and various germs when they pass through a heating, ventilation and cooling (HVAC) system. Strategically installing germicidal UVC lamps in HVAC units helps to purify the air and sterilize HVAC equipment for longer, more efficient use. UV light in HVAC effectiveness is proven to improve indoor air quality for a healthier indoor environment.

UV Light in HVAC Effectiveness

There are several studies that evaluate UV light in HVAC effectiveness with promising results for UV light in HVAC systems in hospitals, offices, and schools. According to a study conducted by American Society of Heating, Refrigerating and Air-Conditioning Engineers, ASHRAE, and Penn State University, ultraviolet germicidal irradiation (UVGI) showed successful results for reducing the amount of fungi in air handling units and cited improvements in children with mold induced asthma when installed in schools.

UV light has been used in hospitals and endorsed by the Centers for Disease Control and Prevention, CDC, for controlling the spread of tuberculosis in hospitals and healthcare facilities. UVC radiation is known to kill harmful microorganisms even antibiotic-resistant “superbugs” like MRSA, SARS and is even proven to be effective at killing the SARS-CoV-2 virus that causes the novel COVID-19.

How are UV Lights Installed in HVAC Systems?

Treating the volume of air in your home or office is immense, and only possible when installed properly in air handling units or HVAC systems since humans cannot be exposed to UVC light. Since the HVAC system draws air into the evaporator unit, forcing it out through air vents and registers throughout the home, UV light installed in the evaporator unit sterilizes the air as it circulates.

Only a professional HVAC technician should install UV lights in HVAC systems for germicidal effectiveness. The lights must be installed in the right area with the right angle of exposure to sterilize the air as it passes through. The HVAC technician will clean the air handler system thoroughly prior to installing UV lights and should inspect all ductwork for leaks. With the right installation by a certified technician, UV lights in HVAC effectiveness will be at maximum levels to prevent airborne infection.

Does UV Light Kill COVID-19?

COVID-19 (Coronavirus Disease 2019) is the disease caused by the novel coronavirus, SARS-CoV-2, which is the cause of a viral outbreak that led to a devastating global pandemic. Public health systems and economies worldwide have been ravaged by this virus and many people are asking the question, “Does UV light kill Covid?”. As of December 31, 2021, the pandemic is experiencing a surge with the new Omicron variant and a total death toll of 5,439,895 globally, with more than 825,816 deaths in the United States. *UPDATE – as of 3/29/23, there have been 761,402,282 confirmed cases of COVID-19, including 6,887,000 deaths globally, and 102,697,566 confirmed cases of COVID-19 with 1,117,054 deaths in the U.S., as reported by the World Health Organization, WHO.

We put together a compilation of several studies showing the effectiveness of UV light for COVID, including how UVC light kills other coronaviruses, how SARS-CoV-2 is transmitted, and UVC lamps that are proven effective at eliminating betacoronaviruses and the SARS-CoV-2 virus that causes COVID-19.

Types of UVC Lamps Effective in Killing Covid

Ultraviolet (UV) light is a type of UV radiation from the sun, that has less energy than X-rays and gamma rays, although has more energy than visible light and radio waves. Sunlight emits natural UV rays in three broad spectrums, UVA, UVB and UVC. People can experience exposure to UVA and UVB rays from natural sunlight, although most UVC natural rays are absorbed by the ozone layer.

UVC light is replicated in manmade germicidal UVC lamps, which have been proven to kill many viruses and bacteria including beta coronaviruses. SARS-CoV-2 is in the beta coronavirus family similar to the MERS (Middle East Respiratory Syndrome) and SARS (Severe Acute Respiratory Syndrome). UVC light is proven effective at eradicating MERS and SARS and recent studies show that UVC lamps are also similarly effective in killing the SARS-CoV-2 virus that causes COVID-19.

Does UV Light Kill Covid in Liquid?

UV light is an effective disinfectant and sterilizer, proven to kill viruses in water, on surfaces and in the air. UVC light effectively inactivates bacteria and viruses by damaging nucleic acids of cells, rendering them unable to replicate. An inactivated cell that is unable to replicate is considered harmless and unable to spread further disease. According to a recent study in the American Journal of Infection Control (AJIC), UVC light is proven effective at killing the SARS-CoV-2 virus that causes COVID-19 in liquid cultures as “SARS-CoV-2 is highly susceptible to irradiation with ultraviolet light“.

UVC lamps are used in UV water disinfection applications such as waste water treatment plants, aqua culture, pool and spa and many additional water sterilization needs.

Does UV Light Kill COVID on Surfaces?

In Laboratories and all Surfaces

UVC germicidal lamps have been shown to be effective at killing the SARS-CoV-2 on surfaces in studies by the AJIC showing a 99.7% effective rate on laboratory surfaces. In order to achieve this high efficacy rate to disinfect surfaces they must be clean and experience direct exposure.

In Hospitals and Medical Facilities

For this reason, many hospitals and medical facilities have added UVC light disinfection to their regular cleaning regimen. UVC light disinfection helps to keep hospital rooms, surgical rooms, surgical and medical equipment sterile and free from harmful bacteria, including some antibiotic resistant superbugs.

UVC Lamps for Restaurant Disinfection

UVC disinfection is helping restaurant owners get back to business and keep their staff and patrons safe. UVC lamps are used in many areas of a restaurant such as disinfecting commercial kitchen surfaces and preventing grease build-up in exhaust fans. Learn the many benefits of UV lamps for restaurants.

UVC Germicidal Lamps

UVC lamps manufactured to emit light in the UVC range are the most effective to kill viruses and bacteria, with standard germicidal lamps designed to emit light at 254 nm. While this wavelength is proven highly effective it can also be damaging to human skin and eyes, therefore some germicidal lamps are designed to emit wavelengths between 207- 222 nm, referred to as Far-UVC light. Far-UVC light is effective at killing germs and viruses and is less hazardous to skin and eyes than other types of UVC lamps.

Does UV Light Kill COVID in the Air?

UV Air Sterilization

Many scientists believe that airborne particles are one of the most common modes of transmission of the SARS-CoV-2 virus, thus sterilizing and disinfecting air in enclosed spaces should help to protect people against contracting the COVID-19 disease. UVC lamps in HVAC units are an effective method of sterilizing air and is utilized in many commercial, industrial, and residential air purification systems.

A recent study published in Scientific Reports concludes that UVC light is effective at killing airborne human coronaviruses including those that cause the common cold and the SARS-CoV-2 virus.

Based on what we know about ultraviolet light, specifically UV light emitted in the UVC range, many studies are showing that UV light may be used as a valuable tool to kill the SARS-CoV-2 virus that causes COVID-19 in liquid, on surfaces and in the air. Far-UVC light may be a good choice for some disinfection applications with less harmful health risks to human exposure.

Germicidal compact lamps are useful in a wide range of applications and industries, including air and surface disinfection. This type of lamp is broken down into one of two primary categories, short (PLS) or long (PLL). PLL lamps provide higher energy density in a compact footprint versus that of traditional linear lamps.

Due to this compact nature, these low-pressure mercury UVC PLL lamps provide germicidal solutions in applications where full-size germicidal lamps may not be an option. Regardless of type, PLL and PLS compact germicidal lamps feature high germicidal efficacy and can aid in the reduction/disinfection of viruses, bacteria, and harmful pathogens in air, water and surface applications.

Compact UVC Germicidal PLL Lamps

Compact PLL germicidal lamps are highly effective at providing disinfection solutions in cost-efficient, geometrically small foot prints. PLL lighting has become a popular choice with plug in versatility typically available in either 2-pin or 4-pin bases.

Germicidal Applications for UVC PLL Lamps

UVC PLL lamps designed to emit ultraviolet radiation in the range of 254 nm is proven to be extremely effective at eliminating various types of harmful pathogens including many types of viruses and bacteria. UVC germicidal lamps are also proven to prevent the buildup of mold and mildew in many environments. UVC ozone lamps are engineered to emit precisely 185 nm of UV radiation and provide sterilization and oxidizing effects such as order control.

UVC lamps designed to produce ozone work in the air without needing direct contact as opposed to 254 nm lamps which must be pointed at the point of sterilization without obstruction. Many types of sterilization systems utilize UVC lamps including short and long PLL lamps to provide a healthier environment with purified air, sterilized water and surfaces.

Germicidal UVC lamps eliminate harmful microorganisms in water and even kill viruses and bacteria that chlorine does not. Compact CFL UVC bulbs provide sterilization solutions to many surface disinfection systems with countless application uses in public, commercial, industrial, and residential settings. UVC lamps help to provide a safer environment in hospitals, restaurants, schools, public transportation systems and more with endless application possibilities.

Far UVC Lamps: Safe and Effective

Far UVC lamps are ultraviolet lamps designed to emit wavelengths in a range of 222 nanometers (nm) as opposed to the typical range of standard germicidal 254 nm UV lamps. There is an increase in Far UVC light technology interest and accessibility with research showing an effective sweet spot to kill germs with people present.  Healthcare facilities and practitioners are discovering the benefits of far UVC light with increased safety and high efficacy.

Far UVC 222nm lamps with the right lamp design can prevent the emission of the longer and more harmful wavelengths, providing the same effectiveness in killing viruses, bacteria, and antibiotic-resistant bacteria.

Far UVC Lamps are Increasing in Usage

UVC lamps have been used for decades as scientists have known that UVC radiation rapidly and effectively kills bacteria, viruses, and microbes. UVC lamps have been shown to effectively eliminate up to 97.7% of harmful pathogens in hospital operating rooms as reported by Technology Networks and many other proven scientific studies.

So why would health practitioners or other users of UVC disinfection technology want to make the switch to Far UVC lamps? Far UVC lamps offer increased safety over standard 254 nm UV lamps without jeopardizing effectiveness.

Increased Safety with Far UVC Lamps

Conventional UVC germicidal lamps are effective at eliminating harmful pathogens in the air, in water, and on surfaces, although they cannot be used in occupied spaces due to potential health hazards. Standard 254 nm UVC germicidal lamps are known to be dangerous to human skin and eyes, making it important that those UV germicidal systems be closed systems with protection mechanisms.  People should also wear proper personal protective equipment (PPE) when servicing or installing traditional UV disinfection systems.

Far UVC lamps, on the other hand, emit shorter wavelengths that significantly reduce the risk of human exposure, and some experts might even suggest that risk is reduced to zero.  This allows for Far UVC light disinfection systems to run constantly without causing harm as opposed to traditional UVC lamps that can only operate in unoccupied spaces.

Far UVC Light Disinfection Effectiveness

Far UVC light at 222 nm allows for safe, continual disinfection and is highly effective at deactivating and destroying pathogens. Far UVC lamps in line of sight disinfection systems can destroy airborne pathogens at the speed of light. According to an article published at UVReporter.com, far UVC light deactivates and destroys pathogens. 254nm light is proven highly effective at inactivating pathogens, although in some cases those pathogens could be reconstituted through a photoreactivation process. Far UVC light is known to deactivate and destroy many pathogens including bacteria, viruses, fungi, protozoa, mold, and other harmful microorganisms.

While far UVC technology has not had the extensive research that traditional UVC wavelengths have had, several studies do suggest that far UVC radiation at 222 nm is effective at destroying a wide range of harmful pathogens. This includes viruses such as influenza, (H1N1), alpha and beta coronaviruses, including the SARS-CoV-2 virus that causes COVID-19, and adenovirus, according to a scientific report, Far-UVC light: A new tool to control the spread of airborne-mediated microbial diseases. 

In another recent study published in March 2022, Far-UVC (222 nm) efficiently inactivates an airborne pathogen in a room-sized chamber, scientists at several different universities came together to test the efficacy of far UVC light in a large room-sized chamber with a ventilation rate the same as a typical office or home, which is about three air changes per hour. The experiment included continuously spraying an aerosol mist of S. aureus bacteria into the room, a microbe that is slightly less sensitive than coronaviruses to far UVC light to provide a conservative model. Far UVC lamps were turned on in commercially overhead systems and in just five minutes, 98% of the airborne microbes were inactivated even though they were continually being sprayed into the room.

This same study verified the high efficacy of far UVC lamps which is often measured in terms of equivalent air changes per hour, with this study producing an equivalent of 184 air exchanges per hour. This far exceeds other approaches to disinfecting occupied spaces indoors where an equivalent of 5 to 20 air changes per hour is typical.

A Future for Far UVC Light

Given the safety and efficacy of far UVC light at 222 nm, the future looks bright for increasing the usage of far UVC lamps which can provide disinfection of the air with any excess radiation extending to disinfecting surfaces. This provides a big advantage of far UVC technology over traditional 254 nm UV lamps.

Ultra Violet Lights: Types and Applications

Ultra violet lights are designed to emit ultraviolet radiation, a form of electromagnetic radiation, with wavelengths in the ultraviolet (UV) range, which is shorter than visible light, although longer than x-rays.

What are UltraViolet Lights?

Ultra violet lights are designed to mimic ultraviolet (UV) wavelengths from the sun, which are typically divided into three basic subcategories.  UV wavelengths are measured in nanometers (nm), with the following distinctions made for the three common bands of ultra violet lighting:

• UVA –  315 to 400 nm, long-wave, not absorbed by ozone layer

• UVB –  280 to 315 nm, medium wave, 95% of UVB rays are absorbed by the ozone layer

• UVC –  100 to 280 nm, all UVC rays are absorbed by the ozone layer

Far UVC light describes ultraviolet wavelengths in the range of 200 to 230 nm, specifically 222 nm, which is gaining interest for many UVC germicidal applications.

All short-wave UVC light and about 95% of UVB rays emitted by the sun are absorbed by the ozone layer. Exposure to UVB light increases the risk of cellular damage to living organisms and is the main cause of sunburns and is thought to be the main cause of skin cancer, the most common form of cancer in the U.S.

UVB light is also, however, the main source of vitamin D to most land vertebrates, including humans. Vit D assists with bone development and helps the body absorb calcium. Ultra violet lighting can be both harmful and beneficial to life. UVB and UVA lamps are also useful for a variety of medical phototherapy applications, such as treating skin conditions, mood disorders, and other health conditions.

All UVA light from the sun reaches the earth’s surface and is the main cause of suntan and skin aging, including wrinkles. UVA damages the skin’s elastin and collagen in the skin and generates free radicals. UVA lamps are the main types of lamps used in tanning beds.

UVC Germicidal Ultra Violet Lights

Exposure to UVC light is also harmful to human skin and eyes, and UVC germicidal lamps should be used in unoccupied spaces. Far UVC lights, however, are gaining recognition as providing highly effective germicidal properties while safer for human exposure and can be used for sterilization purposes in occupied spaces.

UVC ultra violet lights are used in a wide range of germicidal applications and are proven to eliminate harmful pathogens and microbes in the air, in water, and on surfaces. UVC ultra violet lights eliminate airborne pathogens in UV air purification systems and can be used in HVAC systems, including furnaces and AC units, to prevent mold buildup and sterilize equipment as well as the air that passes through the UVC wavelengths.

UVC lamps are also used in many water sterilization systems, and UVC ultra violet lighting can even kill some harmful bacteria in water that chlorine does not kill, such as Cryptosporidium and Giardia. UVC ultra violet lamps are also used for many surface sterilization applications such as in hospitals, laboratories, restaurants, food processing, and many other residential, commercial, and industrial applications.

Ultra Violet Lighting Applications

There are many practical applications, including biological and chemical effects, derived by the way that ultra violet lighting interacts with organic molecules. UVC Ultra violet lights are used in germicidal applications but ultra violet lights perform many valuable functions to many industries.

UV lights are found in many applications and processes such as:

• Germicidal

• Tanning

• UV Curing

• Illumination

• Signs

• Backlighting

• Medical phototherapy

• Specialty purposes

Whatever purpose is planned for the use of ultra violet lighting, it is critical to use quality ultra violet lamps. Not all UV lamps are created, and consulting with an experienced UV lamp manufacturer will help to ensure that you receive the correct type of lamps for your application.

While social distancing, handwashing, and mask wearing are all recommended measures to prevent the spread of disease, providing a sanitary environment where people gather is a must. Business owners increased cleaning and disinfecting measures and explored new sterilization techniques like ultraviolet (UV) light.

UV lamps designed to emit UV electromagnetic radiation in the UVC range have been used for decades to eliminate the threat of viruses, bacteria, and various harmful microorganisms. UVC germicidal lamps are used in air purification systems, water disinfection, and surface sterilization systems worldwide. Ultraviolet germicidal irradiation (UVGI) has been used in upper room air disinfection systems for decades and was a popular measure to protect people against tuberculosis in the 1950s.

UV Germicidal Lamps Help the Entertainment Industry 

With much evidence to back up the effectiveness of UVC germicidal lamps, the entertainment industry has looked to UV technology to remain open during the pandemic and protect patrons. Research has shown that UVC radiation when emitted at the right wavelength and for the proper time period eliminates many types of viruses and bacteria including stubborn antibiotic-resistant bacteria and viruses including beta corona viruses such as MERS, SARS and SARS-CoV-2, the virus that causes COVID-19. 

Germicidal UV lamps are proven to help prevent airborne transmission of disease in air purification systems and can be used in HVAC systems as well as upper room UVGI systems.  Surface sterilization can include handheld countertop disinfection devices or sophisticated UV robots that roam areas of unoccupied spaces.  UV disinfection systems must utilize quality UVC germicidal lamps for maximum effectiveness.

How is Far UVC 222 nm Light Safer than 254 nm UV lamps?

Ultraviolet light emitted in the UVC range (100-280 nm) is highly effective at eliminating harmful germs with standard germicidal lamps designed to emit wavelengths close to the 254 nm range. The specific wavelength is proven to be highly effective at eliminating many harmful pathogens, including bacteria, viruses, mold, fungi, and other microorganisms. Germicidal UVC lamps are used in UV air treatment systems, water purification and surface sterilization systems worldwide. 

The standard germicidal lamps, however, cannot be used in the presence of humans due to the risk of damage to human skin and eyes.

222 Nm Far UVC Lamps Are Safer Than Standard Germicidal Lamps

UVC light emitted precisely at 222 nm is also called Far UVC and is proven to have the same germicidal effectiveness without the risk of human exposure. 222 nm UV light is highly absorbed by the DNA of cells, similar to how cells absorb UV light when in the range of 254 nm. 222 nm light is also absorbed by the proteins that surround the cells, which differs from 254 nm light. 

Proteins are contained in the cell outer membranes of bacteria and viruses, and because they absorb 222 nm UV light, the harmful radiation cannot penetrate into the thick layer of human cells. This protective layer is also found on the eyes, making 222 nm light safer for exposure to human skin and eyes, allowing for use in occupied spaces.

Far UVC lamps designed to emit 222 nm are currently in use in many applications, including medical facilities, hospitals, public spaces, and commercial uses providing effective sterilization and disinfection without the risk of causing harm to human health.

LightSources and LightTech are leading global suppliers of UVC germicidal lamps designed for a wide range of industries and applications. We offer custom design and engineering, and prototype development and are currently developing Excimer lamps to produce Far UVC in the range of 222 nm UV light.

Contact us with any questions and to learn more about all her germicidal solutions  including the efficacy and safety of 222 nm UV light.

How Effective is Far UVC Light at 222 nm?

Far UVC is ultraviolet (UV) light in the range of 207–222 nm, which are shorter wavelengths than the traditional 254 nm UVC lamps.  Interest in far UVC technology is increasing with more research and awareness of the many benefits of UVC lamps engineered to emit wavelengths in the far UVC range. Far UVC wavelengths are shown to provide the same germicidal effectiveness with many benefits such as improved safety. 

Safety of Far UVC vs. Traditional 254 nm UV Lamps

Traditional 254 nm lamps emit powerful UVC radiation highly effective for germicidal applications, although cannot be used when people are present in the room. Traditional UVC sterilization systems must be operated in a closed system, with precautionary measures to shut off automatically if a person enters the room because they can damage human eyes and skin. Far UVC 222 nm lamps emit shorter wavelengths that are shown to operate safely without causing harm to human eyes and skin. 

Far UVC 222 nm Lamp Effectiveness

Far UVC lamps are also shown to be highly effective at killing the same types of viruses, bacteria, and harmful pathogens as traditional UV germicidal lamps, influenza, alpha, and beta coronaviruses. One study conducted by various universities showed that far UVC technology effectively eliminated the threat of airborne bacteria, S. Aureus, while continually spraying into a room. The far UVC lamps and overhead systems eliminated 98% of airborne microbes even though they were continually spraying into the room.

This study and others like it so that the future is bright for far UVC light, with effective disinfection that can be used continually as opposed to only when people are not in the room.

How UV Light Kills Bacteria on Surfaces

Killing bacteria with UV light is a highly effective method of improving health and safety with reliable sterilization and disinfection of many surfaces. Ultraviolet (UV) light is emitted from the sun in basically three different wavelengths, either UVA, UVB, or UVC. UVC is shortwave radiation that is entirely absorbed by the ozone layer. It is these UVC radiation wavelengths, measured in nanometers at the most effective 254 nm wavelength, which eliminates many types of bacteria and viruses. UVC light emitted at 185 nm produces ozone.

UVC germicidal lamp engineers replicate 185 nm UVC radiation for ozone lamps and 254 nm UVC radiation for many other types of effective sterilization lamps. UVC lamps are used in sterilization systems to disinfect surfaces, water, and air with high efficacy and many benefits.

What Types Of Surfaces Can You Disinfect with UVC Lamps?

UVC lamps are beneficial in almost any environment on many types of surfaces. Because surfaces need direct exposure to UVC lamps, when they are already cleaned with manual cleaning methods UVC energy is better absorbed. This is why UVC lamps provide a safety net with additional measures to ensure disinfection when used in conjunction with manual cleaning methods especially in environments like hospitals and medical care facilities.

UVC lamps are being utilized to disinfect surfaces in a wide range of environments such as residential homes, industrial operations, and commercial properties in public places. UVC lamps have been used for decades to sterilize surfaces and hospitals such as surgical equipment and operating rooms as well as patient rooms especially those known to have contracted a serious infection. Germicidal lamps are proven to eliminate bacteria called superbugs. UVC lamps effectively eliminate many types of superbugs like MRSA, C., Diff., E.Coli, Salmonella and many others making them a great addition to hospital sterilization methods

UVC robots are becoming more popular as they provide effective sterilization after manual cleaning crews have left a patient room and can reach many places missed by manual cleaning methods.

UVC lamps are beneficial to sterilize surfaces in many environments such as:

• Hospitals

• Restaurants

• Food irradiation

• Industrial commercial properties

• Schools

• Libraries

• Public transportation systems

• Residential homes
