UV Disinfection Lamps in HVAC Systems

Ultraviolet (UV) lamps designed to emit UVC radiation have long been used for effective disinfection and sterilization purposes. Lighting engineers re-create UVC light which is naked to the human eye, and the shortest wave of UV light that is fully absorbed by the ozone layer. UVC radiation packs powerful germ-killing properties and quickly kills a variety of viruses, bacteria, and microorganisms within seconds of contact.

UVC lights have been used in many disinfection applications for decades, such as air purification systems, water disinfection systems, and surface sterilization applications. 

Benefits of UVC Lamps in Air Purification Systems

UVC lamps in air purification systems prevent many airborne diseases by purifying the air and cleansing air from harmful contaminants while circulating and exposed to UVC lamps. UV lamps in HVAC systems are becoming more popular as many people realize the benefits of removing harmful contaminants from the air and preventing airborne disease.

Germicidal UV lamps in HVAC units provide additional benefits of protecting equipment and air condenser coils against the formation and buildup of mold and mildew. UVC lamps are known to prevent mold and mildew, which helps equipment to run smoother, more efficiently, and last longer.

How UVC Lamps Kill Airborne Viruses

UVC radiation quickly penetrates the DNA of harmful cells, altering the genetic makeup of these microorganisms, which renders them unable to reproduce. Cells that cannot reproduce are rendered harmless without the needed proteins to replicate or survive. Many studies show high efficacy with germ-killing properties of UVC germicidal lamps in air purification and HVAC systems.

UVC lamps should only be installed by a professional in HVAC systems as exposure to UVC radiation can be harmful to human eyes and skin.

Vitiligo is an autoimmune disorder which causes white patches to appear on the skin due to a progressive loss of melanocytes, melanin forming cells. These colorless patches on the skin have distinct margins, are non-scaly, and typically will get larger over time. They may also appear inside of the nose and mouth, and loss of color can also affect hair and facial hair.

UVB Lamps for Vitiligo Provide Successful Treatment

Ultraviolet, UV lamps designed to emit narrow band UVB give patients hope for a positive prognosis when properly administered. UVB lamps for vitiligo are considered safe under the proper direction and are typically administered in the office of a dermatologist. Ultraviolet lamps are most effective at restoring skin pigmentation on patients with vitiligo on the neck and face; white patches on fingertips, toes, and the lips are less responsive to UVB phototherapy.

Narrowband UVB Proven Effective Treatment for Vitiligo

Narrowband UVB lamps were shown to provide nearly 75% repigmentation on 63% of patients receiving phototherapy for vitiligo twice per week over the course of one year in this study published by the National Library of medicine.

UV phototherapy lamps are useful in treating and providing relief to a variety of ailments and illnesses. 

Phototherapy lamps are proven to treat many health conditions, including:

Neonatal jaundice - UV lamps are the main source of treatment to break down bilirubin in the blood that occurs when an infant’s liver is not yet fully capable of breaking down the toxins in the body.  “Bili” lights help the baby’s body and prevent brain damage. 

Mood disorders, depression – many people experience Seasonal Affective Disorder (SAD) during the winter months with less sunlight. Light therapy lamps help to treat depression which can be mild to severe and can improve symptoms of fatigue, lack of interest, and many other depressive symptoms. 

Sleep disorders – phototherapy lamps treat sleep disorders, including jet lag, by helping the body to regulate the natural circadian rhythm. 

Light therapy lamps also treat a host of skin conditions and are prescribed by dermatologists to ensure the right wavelength is used to treat specific conditions such as: 

Acne – UV light is proven to help treat acne, which affects nearly 60 million people in the U.S. Topical treatments can minimize symptoms, but many are ineffective, leaving people looking for help. Combinations of red and blue light therapy have been proven successful in treating acne to reduce outbreaks and lessen the severity of symptoms. 

Eczema – UV light is useful for successfully treating eczema with UVA, UVB, and narrow-band UVB wavelengths that reduce symptoms and help to clear skin. 

Psoriasis – light therapy helps to treat psoriasis by successfully lessening the severity of symptoms and preventing outbreaks.  Sometimes medication called Psoralen is used in conjunction with UVA and UVB wavelengths to help absorption for successful treatment. 

Vitiligo – UV lights treat vitiligo which is a skin condition that leaves white patches on the skin due to a loss of melanin. Narrowband UVB lamps are a popular way to treat vitiligo and help repigment skin cells.

Ultraviolet medical phototherapy lights are used to treat these conditions and others, such as helping wounds to heal by increasing blood circulation and preventing infection. Photodynamic therapy, PDT, is a treatment where UV blue light is used in conjunction with medications to treat certain types of cancer and kill cancer cells or tumors of atypical growth. 

As you can see, ultraviolet lamps have vast healing power, although the right type of lamp with the correct wavelength must be used to treat each condition. It is important to use light therapy correctly under a physician’s care.

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.

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

UVC germicidal lamps provide high efficacy up to 99.9999% elimination of bacteria and viruses, are low maintenance without the need to purchase, store or dispose of harmful chemicals and leave no hazardous byproduct. The quality of UVC germicidal lamps makes a difference in the efficacy and lifetime performance.

How UVC Lamps are Helping Hospitals

Hospitals provide lifesaving treatments with modern medicine and staff dedicated to healing sick individuals. Unfortunately, as much effort is focused on sanitizing and sterilizing all surfaces in hospitals, many people contract an additional illness from a hospital stay when seeking treatment for a health condition. The Centers for Disease Control and Prevention, CDC, estimate that approximately 1 in 25 people who are admitted as patients to a hospital contract an additional infection from their hospital stay. This is referred to as a hospital acquired infection, HAI, and it is estimated that approximately 100,000 people die every year from an HAI in the United States.

UVC Germicidal Lamps Help Sterilize Hospitals

Surfaces in hospital patient rooms and stagnant air circulating through hospitals can create a breeding ground for bacteria and viruses. Patients ill with antibiotic resistant infections, commonly called superbugs, can leave behind transmissible germs even with thorough manual cleaning.  UVC germicidal lamps significantly improve sterilization rates when combined with manual cleaning tactics and are proven effective at eliminating many superbugs such as MRSA, SARS and even the Sars-CoV-2 virus that causes COVID-19. 

UVC Lamps Sterilize Air, Surfaces, and Water

UVC germicidal technology is utilized in hospitals in a number of ways.  UVC germicidal lamps installed in HVAC, air-conditioning units or upper room ultraviolet germicidal irradiation, UVGI, units are proven to improve indoor air quality, sterilize and purify the air. UV sterilization lamps are also utilized to disinfect many surfaces in hospitals including operating rooms, patient rooms, and to directly sterilize medical equipment and surgery devices.  UVC lamps are also used in water applications to prevent bacteria, mold or mildew and ensure clean and sterile water.

UVC Robots Help Hospitals Stay Clean

In addition to UVC germicidal lamps used in air, water, and surface sterilization systems, UVC robots are becoming more popular in hospitals and many other public places. Robots equipped with UVC sterilization lamps can roam hospital rooms and reach places that manual cleaning cannot reach, providing a safety net with powerful UV radiation proven to kill viruses and germs.

Does UV Light Kill Covid?

The novel coronavirus, SARS-CoV-2, is the virus that causes COVID-19 and a devastating global pandemic that began in early 2020. As of January 1, 2022, according to the John Hopkins Coronavirus Resource Center Global Map, there have been 5,442,655 deaths globally and over 825,982 deaths attributed to COVID-19 in the U.S. alone. Public health systems and economies continue to struggle against the changing variants such as the latest omicron variant which is spreading rapidly.

For more than 100 years, ultraviolet (UV) radiation has been used to disinfect and sterilize many environments, and public health officials are realizing that UV light provides an added layer of protection against infection from many viruses and bacteria, including SARS-CoV-2.

Does UV Light Kill Covid?

According to an article published by the American Journal of infection control, regarding the Susceptibility of SARS-CoV-2 to UV irradiation, published in August 2020, UV light effectively sterilizes a wide range of microorganisms and is an added tool for use in reaction to the ongoing COVID-19 pandemic. While more research has yet to be completed regarding the exact dosage and exposure time of UVC radiation to the SARS-CoV-2 virus, UVC sterilization systems are proven to eliminate other coronaviruses in the same beta coronavirus family. UVC radiation effectively eliminates the viruses that cause MERS and SARS, other respiratory outbreaks caused by a coronavirus.

A recent article published in Medical Life-Sciences, explains how UVC sterilization systems can be an extra layer of defense against the SARS-CoV-2 virus. UVC sterilization systems can be utilized in many public places including hospitals, restaurants, hotels, airports, universities, public transportation systems and more. 

Exposure to UVC radiation can harm the skin and eyes.  These systems such as UVC robots should be used without direct exposure to human contact and under the advice of a professional with correct UVC disinfection systems properly installed for maximum efficacy and operation.

How Phototherapy Helps Eczema

According to the National Eczema Association, eczema refers to a group of skin conditions that cause different symptoms such as itchiness, inflammation, and dry patches of skin. Eczema is quite common with more than 31 million people in the U.S. having some type of eczema. There are seven different types of eczema which include:

1. Atopic dermatitis

2. Contact dermatitis

3. Nummular eczema

4. Neurodermatitis

5. Seborrheic dermatitis

6. Stasis dermatitis

7. Dyshidrotic eczema

Eczema can appear any time from childhood to adulthood with symptoms ranging from mild to severe. The exact cause of eczema is unknown although we do know that it is not contagious and seems to develop from a combination of environmental triggers and genes.

One common treatment for eczema is light therapy, which can help to reduce symptoms of itchiness and inflammation in children and adults.

What to Expect with Phototherapy for Eczema?

Patients find relief with light therapy for eczema which should be prescribed by your doctor with specialized UV phototherapy lamps. Phototherapy lamps emit either UVA or UVB wavelengths with narrowband UVB proven effective to treat eczema. Phototherapy lamps can be used to treat just certain areas or the entire body where patients would stand in an enclosed area with protective eyewear while being exposed to phototherapy lamps. 

Sometimes a cream or lotion can be applied prior to UV exposure, or medication called psoralen may be used in combination with UVA treatments to provide better results. It may take a month or two of regular visits to see an improvement, although some patients can experience remission and reduce the number of visits. 

Many people with eczema experience flare-ups during fall and winter with less sun exposure. For those patients with improved skin conditions during the summer months, light therapy is more likely to provide positive results.
