Does UV Light Kill Candida Auris?

Candida Auris is a formidable fungal pathogen that poses a serious threat to healthcare facilities worldwide. As a resilient organism capable of causing severe infections, it is crucial to explore effective methods of eradicating it from surfaces.

Surface Sterilization: Harnessing the Power of UV Light to Combat Candida Auris

In recent years, the use of UV light has gained attention as a potential solution for combating this elusive fungus. One question that many healthcare professionals want to know is, does UV light kill Candida Auris? There are several scientific studies and evidence that explore Candida auris and the application of germicidal UV lamps for surface sterilization.

Understanding Candida Auris and its Spread

It is essential to understand the nature of Candida Auris and its mode of transmission to understand the most effective application of UV light to kill this harmful pathogen. Candida Auris primarily spreads through contaminated surfaces in healthcare settings. It can survive for extended periods on various surfaces, including medical equipment, furniture, and hospital room fixtures.

Candida auris is recognized as an emerging fungus that poses a significant global health risk to people worldwide. There are three primary reasons why the Centers for Disease Control and Prevention, CDC, is concerned about C. auris:

• It is frequently multidrug-resistant, which indicates that it is resistant to numerous antifungal medicines, which are often used to treat infections caused by Candida. There are some strains that show resistance to all three kinds of antifungals that are now accessible.

• It is challenging to identify using ordinary laboratory methods, and incorrect identification may occur in laboratories that do not have specific technology. A misunderstanding of this circumstance could result in incorrect management.

• Candida Auris has been responsible for outbreaks throughout many medical facilities. Because of this, it is essential to conduct a speedy diagnosis of C. auris in a patient who is currently being treated in a healthcare facility so that these facilities may take additional safety measures to prevent the infection from spreading.

The Power of UV Germicidal Lamps

Germicidal UV lamps have been widely used for disinfection purposes due to their ability to inactivate a broad range of microorganisms, including bacteria, viruses, and fungi. UV-C light, with a wavelength range of 200-280 nanometers, is particularly effective in destroying the DNA and RNA of these pathogens, rendering them unable to replicate.

Scientific Evidence on UV Light and Candida Auris

Several studies have investigated the efficacy of UV light in eradicating Candida Auris. One notable study published by the National Institute of Health concludes that C Auris can effectively be killed with UV light surface sterilization, with the density of the C Auris, and the distance and time of UVC exposure strongly influencing the efficacy of UVC treatment to kill this harmful fungal pathogen. The researchers concluded that UV light can be a valuable tool in preventing the transmission of Candida Auris in healthcare environments.

Application of UV Light for Surface Sterilization

UV light can be applied for surface sterilization in various healthcare settings, including hospital rooms, operating theaters, and medical equipment. UV Germicidal lamps can be strategically installed to target high-touch surfaces, such as bed rails, door handles, and tables. By implementing regular UV disinfection cycles, healthcare facilities can significantly reduce the presence of Candida Auris and other pathogens.

In the battle against Candida Auris, surface sterilization plays a vital role in preventing its transmission within healthcare settings. UV light, particularly UV-C irradiation from germicidal UV lamps, has demonstrated effectiveness in eradicating Candida Auris on surfaces. By harnessing the power of UVC light for surface sterilization, healthcare facilities can enhance their infection control measures and protect patients from this resilient fungal pathogen.

Where Is UV Light on the Electromagnetic Spectrum?

Electromagnetic energy travels in waves and covers a very wide spectrum from short gamma rays to long radio waves, with x-rays, visible light, and UV light in between. Only a small portion of this electromagnetic spectrum is visible light that the human eye can detect. An x-ray machine detects a different portion of the spectrum, and a radio detects yet another portion of this spectrum. 

People use electromagnetic energy every day, when they send a text message, watch television, listen to the radio, or use a microwave oven. The world as we know it would not exist without electromagnetic energy.

UV Light and Visible Light

Ultraviolet (UV) light is actually not visible to the human eye, with shorter wavelengths than visible light. Visible light can be seen at wavelengths measuring from about 400 to 700 nm, with 400 nm light being purple or violet in color. UV light is emitted in shorter wavelengths in the range of 100 to 400 nm, closest to the violet color on the visible spectrum, thus is coined beyond violet, or ultraviolet.

UVA, UVB, & UVC

Ultraviolet radiation has many practical uses and provides many benefits to industries and applications to help the human race.  Ultraviolet light is further broken down into three categories, UVA, UVB, and UVC light.  UVC is the shortest wavelength and, when emitted from the sun, is completely absorbed by the ozone layer, although it is proven to provide powerful germicidal properties. 

Scientists and lighting engineers replicate UVC radiation when manufacturing UVC bulbs that provide powerful germicidal properties in many environments, including air disinfection, surface, and water sterilization. UVB lamps are commonly used in many medical phototherapy applications, bringing relief to a wide range of people suffering from skin disorders, acne, psoriasis, and eczema, and also helping people with mood disorders and depression. UVA lamps are also useful in medical phototherapy applications and are also the commonly known black light. Black lights do much more than illuminate psychedelic posters, they help crime scene investigators identify organic material and bodily fluids and help prevent fraud with currency validation.

No matter what type of UV light bulbs you require, working with a reputable UV lamp manufacturer is the best way to ensure quality lamps, as not all UV lamps are created equal.

LightSources is recognized as a leading global supplier of UV light bulbs with a wide selection of standard shapes and sizes and custom options available, including UV light tubes, U-shaped lamps, and custom designs.

UV Efficiencies in AC Units

Almost everyone enjoys the refreshing comfort of an AC unit in their home, commercial or industrial location during the heat of summer. But along with that comfort come microorganisms, mold, and mildew inherent in the passageways of an AC system. These unwanted intruders make the system work harder and shorten the mechanisms’ operating life.

AC Units: Breeding Ground for Pathogens

They can also cause a variety of ailments, including colds, allergies, COPD, bronchitis, asthma, headaches, and nausea. More serious illnesses include lung infections, pulmonary disease, autoimmune deficiency, and even cancer. This can cause serious long-term health consequences, even for those with no other underlying health conditions.

No amount of human labor, even by a licensed professional, can eliminate all the microorganisms and spores that collect in the vents, coils, and drain pans, and along the other interior surfaces of an AC system. Even the highest-quality HEPA filter cannot trap all the potentially toxic microscopic pathogens and volatile organic compounds (VOCs) that escape the AC system. The application of chemicals will only dispel toxins into the same area the AC blower system is intended to service.

UV Light Prevents Build-Up and Improves Efficiency

The answer is to install, with a new AC unit or as a retrofitted adjunct to an existing unit, a UV light sterilization system, particularly with light in the frequency of 253.7 nanometers (commonly referred to as 254 nm). UV light at that pinpointed frequency will instantly destroy the nucleus of each microorganism that passes through its radiation. Such UV light purification systems will work with optimum efficiency at temperatures ranging from 40° to 120° F, can be programmed to radiate 24/7 or only in tandem with the AC blower, and are virtually maintenance free, with bulbs lasting several thousand hours.

The UV in-duct version of AC purification systems should be mounted near and downstream from the system’s coil and should be aimed at the coil and condensation pan. The efficiencies gained from installing a UV germicidal AC purification system are many and varied. Families will be healthier, with less time spent taking the kids to the doctor. Workforces will operate more efficiently with greater productivity and decreased absenteeism.

LightSources is a leading global supplier of high-quality UV germicidal lamps to suit HVAC sterilization needs.  We design, engineer and manufacture high-tech germicidal lamps to meet various disinfection system needs and OEM specifications. Contact us to learn more about our many options for UVC germicidal lamps.

Keeping Food Safe with UV Light

In the food growing, processing, and service industries, a lot of things can go wrong. Dangerous contaminants lurk around seemingly every corner during each step of the process of bringing food from the field to the table. As a result, the agricultural, food processing, and restaurant businesses are subject to some of the most stringent regulations, resulting in increased costs, both to producers and consumers.

UV light food sterilization equipment can play an indispensable part as a silent partner in keeping food safe and of optimal quality for human consumption. UV light can be used to destroy harmful microbes, viruses, and other microorganisms that can threaten to shut down a business, temporarily or permanently, through substantial government fines, product recalls, costly litigation, and their resultant bad publicity.

UV Food Sterilization Keeps Food Fresher Longer

Properly installed and operated, UV light food sterilization systems can effectively and efficiently ensure that food and beverage products are free from the harmful microorganisms that human effort alone cannot begin to adequately combat. The result is a safer end product that stays fresher longer, increasing shelf life and preventing premature sprouting of foods like potatoes and onions.

Products during processing are invariably exposed to the air and various surfaces within the sphere of operation. UV germicidal lamps can continuously sterilize such air and surfaces, along with any water used for rinsing products or included as an ingredient in the production process. Surfaces may include everything from tables to slicers and grinders to pans, bottles, and conveyor belts, to the final packaging material, all of which can be constantly sanitized by UV light.

UV light sterilization systems are relatively low cost and very low maintenance, and eliminate the need for chemicals, herbicides, and pesticides. Examples of food industries efficiently and effectively benefited by UV light sterilization systems are beef, fish, and poultry producers; dairy and cheesemakers; beverage companies; liquid sweetener manufacturers, such as corn syrup; frozen food companies; bakeries (where UV light was first used to treat flour and yeast to eliminate insects); fruit and vegetable producers; and chocolatiers.

LightSources is a leading supplier of UVC germicidal lamps, found in air, surface, and water sterilization applications around the globe. We offer a wide selection of UV lamps and equipment to meet the needs of any surface, water or air sterilization system.  Contact us to speak with an engineer about our high-tech UV germicidal lamps.

Do UV Lamps for Furnaces Really Sterilize the Air?

Ultraviolet radiation in the UVC range has long been proven to be an effective method of sterilization to eliminate bacteria, viruses, and pathogens. UVC lamps designed to emit wavelengths in the range of 254 nanometer (nm) have powerful germicidal effects.  UVC radiation in the most optimum wavelength penetrates the DNA of cells in pathogenic microorganisms to render them unable to replicate, thus considered harmless. 

UVC lamps used for sterilization are effective in water, on surfaces and in air purification systems.  UV lamps are also used in furnaces and HVAC systems to help prevent the spread of airborne disease and microbial growth on HVAC internal surfaces like exchanger coils. UVC sterilization lamps aimed at the coils in a furnace and AC unit prevent the build up of mold, bacteria and fungi in the damp, dark areas prone to microbial growth. 

An article published by the National Institutes of Health concludes that UV lamps are an effective method to reduce the fungal contamination in air handling units.   

UVC Lamps for Furnace and Air Purification

Germicidal UV lamps come in various shapes and sizes although must be engineered to emit the proper wavelength.  UVC ozone lamps are also used in air purification systems as ozone can sterilize the air without needing direct exposure while also eliminating foul odors from the air.  UV ozone lamps are designed to emit UVC radiation in the wavelength of 185 nm, which is an effective deodorizer. 

UV lamps must be installed in your furnace by a professional to ensure optimum sterilization and safety.  LightSources is a leading global supplier of high-quality UVC germicidal lamps and UVC ozone lamps used in air sterilization applications worldwide. 

LightSources offers a wide selection of UVC germicidal lamps for use in air purification systems as well as water and surface sterilization.  We employ the leading high-tech engineers in the industry with vast technical knowledge of UV radiation.  Contact us to learn more about our UVC germicidal lamps for furnace and air purification systems.

Do UV Lights in HVAC Systems Improve Air Quality?

Ultraviolet (UV) lamps designed to emit wavelengths in the short wave UVC range have germicidal properties which eliminate harmful bacteria and viruses.  UVC lamps designed to emit wavelengths specifically close to 254 nm for germicidal applications and 185 nm for ozone applications are most effective.  Germicidal lamps are proven to quickly eradicate even stubborn bacteria such as antibiotic resistant superbugs and inactivate viruses, including beta coronaviruses such as MERS, SARS, and SARS-CoV-2 which is the virus that causes COVID-19. 

By cleaning the air that passes through air handling units of HVAC systems, UV lights in HVAC systems help to improve indoor air quality and also prevent mold and fungi from building up on internal HVAC components. This is one of the biggest benefits of UV lights for HVAC systems, as heating coils are susceptible to contamination, a build-up of mold and fungi due to the moist environment. UV lamps directed at heating coils and in ducts prevent mold build up and contamination, thus improving HVAC performance and energy efficiency.

UV Lamps in HVAC for Residential, Commercial, and Industrial

UVC lamps have long been used in the medical field and in hospitals to protect patients and staff from lingering viruses and bacteria. Upper room ultraviolet germicidal irradiation (UVGI) is proven to help protect patients against tuberculosis and has been used for decades with guidance from the Centers for Disease Control and Prevention, CDC, an environmental control of tuberculosis bacteria with UV lamps in upper room UVGI for air sterilization. 

Several additional studies examine the effectiveness of UV lamps in HVAC systems for air sterilization and purification, such as the study by Dick Menzies, et al, published in the National Institutes of Health, which examined the effects of UV air purification lamps on work related illnesses and symptoms of employees. The study showed a clear correlation between improvements in health-related worker symptoms when UV lamps were used in HVAC systems to promote improved indoor air quality.

Can UV Lamps Help Protect My Restaurant?

For more than a year, businesses and global economies have been negatively affected by the COVID-19 pandemic, with restaurants forced to shut down or limit capacity in nearly every state across the country. With the vaccination rollout and a light at the end of the tunnel, states are loosening restrictions with more business openings. Business owners and owners of restaurants everywhere are searching for ways to ensure the safety of their staff and the public. 

Restaurants have increased manual cleaning methods such as wiping down surfaces and counters with antibacterial disinfectant cleaners, forcing mask mandates and practicing social distancing. Many restaurant owners want to know if UV lamps will help them provide a cleaner and safer environment. UVC germicidal lamps are an excellent, effective, and reliable tool that drastically improves disinfection and sterilization goals with many unique, additional benefits for restaurant owners. 

UVC Lamps Provide a Host of Benefits for Restaurants

UVC germicidal lamps for restaurants serve many purposes to improve sterilization processes and safety for staff and patrons.  UV lamp technology can be used in many areas and devices to sterilize the air in public dining places, restrooms, and kitchens. UV lamps sterilize surfaces in restaurants and commercial kitchens to prevent the spread of disease on counters and utensils, and can also be used for food irradiation, a safe and effective method of preventing foodborne illnesses.  

Food Irradiation

Food irradiation with UVC lamps is an approved method by the FDA to tread many food types such as:

• Fruits and vegetables 

• Meats and poultry

• Various dairy products

• Beverages 

UV Surface Treatment

UV surface treatment in restaurants helps to eliminate foodborne diseases such as E. coli and Salmonella.  UV lamps can be placed above food buffets, delis, food preparation counters, and food storage areas. 

UV Lamps for Walk-in Freezers

UV lamps help to prevent mold and mildew in areas susceptible to excessive moisture such as a walk-in freezer. 

UV Lamps in Kitchen Hood Exhausts

UV lamps in commercial kitchen hood exhausts prevent the build-up of grease, thus reducing the risk of fire and increasing cleanliness.  

Upper Room Air Disinfection

Restaurants can incorporate upper room Ultraviolet Germicidal Irradiation (UVGI) in UV air sterilization units mounted in public areas, restrooms, and kitchens.  UV lamps may also be incorporated into HVAC systems providing a continual defense against spreading airborne disease.

UVC lamps are an important tool in helping to prevent the spread of harmful viruses, bacteria, mold, mildew, fungi, and other harmful pathogens. Ultraviolet radiation is proven effective in sterilizing water, surfaces, and air in a variety of UV sterilization devices including UVC robots, HVAC applications and various water and surface sterilization systems.

Do UV Lamps Kill the SARS-CoV-2 Virus That Causes COVID-19?

Ultraviolet (UV) light is a type of electromagnetic radiation that has more energy than visible light but less energy than x-rays and gamma rays. UV light from the sun is replicated in UV lamps for things like tanning beds and disinfection applications. UV light is broken down into different spectrums mainly UVA, UVB and UVC light. 

UVC light is the wavelength with germicidal effectiveness and is mostly absorbed by the Earth’s ozone layer before it reaches the ground. UVC germicidal lamps are designed to emit wavelengths at the optimal nanometer to kill germs which is typically 254 nm or 185 nm for ozone lamps.  According to the study Upper-room ultraviolet air disinfection might help to reduce COVID-19 transmission in buildings: a feasibility study by the National Institutes of Health, several studies have demonstrated that the SARS-CoV-2 virus that causes COVID-19 is relatively easily inactivated by UVC disinfection lamps similar to other airborne coronaviruses.  Additionally, conclusions from this study state that Upper Room Ultraviolet Germicidal Irradiation (UVGI) with UV light at 254 nm has the potential to inhibit the transmission of COVID especially in confined places like hospital rooms or public places or anywhere that achieving a high ventilation rate is not practical.

UV Lamps in HVAC Systems Fight Spread of Disease

The use of ultraviolet (UV) light in disinfecting and sterilizing surfaces is gaining as part of the fight against the spread of the novel coronavirus and to control health acquired infections (HAIs) in hospitals. HAIs are a serious problem for hospitals, especially when stretched at capacity and short on staff.  Even prior to the COVID-19 pandemic, nearly 1 in 25 patients were estimated to contract an HAI from a hospital stay, some with dire consequences. Protecting patients and staff against HAIs including drug-resistant bacteria and serious viruses with effective hospital disinfection is top priority for hospitals and healthcare facilities. 

Nearly everything that is in a hospital room from all the surfaces to airborne particles, medical equipment and the clothing and hands of healthcare workers can serve as a reservoir and vector for transmitting opportunistic pathogens.  While contaminated surfaces and insufficient hand hygiene are the primary modes of transmission, water and air supply systems also provide a mode of transmitting harmful pathogens.

UVC HVAC Air Purification Systems

While maintaining regular cleaning and manual disinfection practices is crucial in hospitals, along with proper hand hygiene, germicidal UVC lamps in moving air applications are proven to disinfect and purify the air. Ultraviolet Devices, Inc, UVDI, offers HVAC air disinfection and purification systems with advanced UV technology. UV air disinfection eliminates viruses and bacteria with a kill rate up to 99% and UV air purification destroys volatile organic compounds (VOCs) and foul odors.

UV moving air applications include two basic systems for UVGI as a supplemental air cleaning measure:

Upper room air irradiation – UVGI lamps are wall mounted above an occupant’s level, usually 8 feet above the floor and irradiate the airflow in the room.  Upper room UVGI has been used in tuberculosis wards to inactivate TB and is also effective in patient rooms, emergency rooms, waiting rooms, hallways and anywhere patients could potentially spread airborne germs.

HVAC Duct Irradiation – UVC germicidal lamps placed inside HVAC and air handler ducts disinfect recirculated or outside air. UVC lamps in air handling units effectively eliminate microscopic organisms that are too small to filter yet are easily disinfected with UV light.

LightSources offers high-quality UVC lamps found in UV sterilization systems for hospitals including air disinfection UVGI mounted, HVAC and portable systems  Our UVC robot lamps are helping hospitals to improve patient and staff safety and prevent the spread of disease with effective surface sterilization.

Does Ultraviolet Radiation Kill the COVD-19 Virus?

Ultraviolet radiation is proven to kill viruses and bacteria and there have been many questions about the efficacy of UV light killing the novel coronavirus.  The current pandemic with the outbreak of COVID-19 is caused by the coronavirus SARS-CoV-2, and people want to know if they can purchase UV lights for their home to help protect themselves and their family with effective sterilization.  Hospitals have been using UVC lamps in surface sterilization devices and UVC robots to further sterilize patient rooms and surfaces.

The U.S. Food and Drug Administration, FDA, answers your questions about UV Lights and Lamps: Ultraviolet-C Radiation, Disinfection, and Coronavirus. 

UVC Radiation and the SARS-CoV-2 Coronavirus

UVC radiation is proven to destroy the SARS-Coronavirus, which is a different coronavirus than what causes COVID-19.  SARS-CoV-2 is the virus that causes COVID-19 and given the newness of the virus there are many ongoing research studies to verify accurate dosage of UVC exposure including exposure duration and distance, which is key to effective sterilization with germicidal UVC lamps. 

Studies like this one by Boston University are showing promise with results that show a 99% reduction of the SARS-CoV-2 virus when UVC radiation is dosed at the right level.  This study shows that UV light will deactivate the coronavirus in 6 seconds when dosed at 5 mJ/cm2.  Another study conducted by Biological Consulting Services in Feb.2020, shows effective elimination of SARS-CoV-2 virus and many other stubborn microorganisms in UVGI irradiation with 99.99% effectiveness with 15 minutes of exposure.  With surface sterilization at direct exposure and UVGI air irradiation, hospitals can significantly improve the health of patients and prevent the spread of disease. 

Hospitals using UVC light to eliminate the spread of disease and consumers wishing to purchase UVC lamps to sterilize surfaces at home must remember that direct exposure is key.  UVC radiation will only kill microorganisms that are directly exposed to the UVC radiation emissions.  Inactivation of the virus on surfaces will not be as effective if blocked by shadows, dust, soil or organic compounds which absorb the UV light and reduce the efficacy of sterilization on the surface.

UV Light Prevents Grease Build Up in Kitchen Exhaust

Kitchen hood exhaust systems in commercial kitchens serve a very important purpose, to pull grease particles up and away through mechanical filters.  Kitchen exhaust systems vent excess heat above kitchen stoves and extract grease particles, leaving smaller particulates that may linger in the hood exhaust system.  These kitchen exhaust systems can encounter grease build-up in the vents if they are not cleaned regularly or treated with UV light sterilization solutions. 

How Does UV Light Help Kitchen Hood Exhausts?

Ultraviolet (UV) light emits UV radiation, electromagnetic energy, and is harnessed in UV germicidal lamps used in a vast range of applications.  UV light is used to purify the air, disinfect water and sterilize surfaces.  Utilizing UV light in kitchen hood exhaust systems provides many benefits beyond sterilization.  Kitchen hood UV exhaust systems can actually prevent grease build-up in the exhaust duct work.  

UVC lamps break down grease through photolysis and ozonolysis. UV light causes a photochemical reaction, breaking down the molecular bond while ozonolysis oxidizes the grease molecules. By breaking down the grease particles, they are converted into particles that are much easier to clean and do not build-up grease in the kitchen hood.  

This brings many benefits to restaurant owners by mitigating the risk of a grease fire, which can often occur with grease build-up in the exhaust hood.  UV kitchen exhaust systems also help kitchens to meet stringent health department code regulations by helping to keep the kitchen cleaner.  This provides a better work environment for employees and helps to maintain health standards for patrons. 

UV Lamps are Key to Successful UV Sterilization Systems

Using the right UV lamps for your UV kitchen exhaust sterilization system is key to successful prevention of grease build-up and sterilization.  UV germicidal lamps designed to emit 254 nanometer (nm) are effective in sterilizing air and surfaces.  Ozone producing lamps emit UV energy at 185 nm and are commonly used in air and water disinfection applications, deodorizing the air and reaching places that standard UV radiation cannot reach. 

When searching for the best UV lamps for your sterilization application, contact an experienced UV lamp manufacturer like LightSources. 

LightSources leads the industry in UVC germicidal lamp production, with a wide range of low-pressure, amalgam and many other lamp types designed with proprietary technology.  We provide high-quality UVC lamps proven to outlast and outperform comparable lamps of the same size.  Contact us to learn more and for custom lamp requirements for your UV germicidal application.

Solutions for Challenges Facing Hospital Disinfection

Disinfection practices in hospitals have always been of great concern with the number of patients carrying viruses and bacteria, and the potential exposure to patients with compromised immune systems.  Hospital acquired infections are infections that occur within the first 48 hour of being admitted to the hospital, within the first three days following a hospital discharge or within the first 30 days after an operation.  The Center for Disease Control, CDC, estimates that approximately one in every 25 of hospital patients in the U.S. contracts a hospital acquired infection (HAI).  Many HAIs are resistant to treatment with antibiotics and can lead to sepsis or even death. 

HAIs and disinfecting patient rooms are of great concern for hospital staff for many reasons:

• Patients being discharged may have had a contagious, serious viral or bacterial infection

• Incoming patients are already ill and may have a compromised immune system

• Hospital staff move from room to room and have a high potential to carry pathogens from one patient room to the next

Hospital Cleaning Practices

Hospitals take their cleaning, sanitizing and disinfecting practices very seriously. Even with the most careful cleaning procedures, human error can contribute to less than sanitary conditions. Disinfecting patient rooms thoroughly can be challenging due to many factors such as:

• Using contaminated cloths which spread disease

• Using diluted disinfectant cleaning solutions

• Insufficient contact time of cleaners with surfaces

• Human error, cleaning staff can miss an area when manually cleaning

Adding UV Light Disinfection

Adding UV light disinfection to standard hospital cleaning practices has been proven to greatly increase sterilization success. UV light in shortwave UVC radiation quickly eradicates many viruses and bacteria with high efficacy and can reach into places that manual cleaning cannot access.  

UV germicidal lamp manufacturers design and engineer UVC lamps to emit the most powerful wavelength of UVC radiation at 254 nanometer.  UVC radiation penetrates the cells of viruses and bacteria, rendering them unable to replicate and leaving them harmless. High-quality UVC germicidal lamps are the key to effective UV sterilization.

LightSources is a leading global supplier of UVC germicidal lamps, with a wide range of UV germicidal lamp types.  We offer standard low-pressure mercury lamps, amalgam lamps with proprietary technology, Germipak, U-lamps and custom engineered solutions.  Contact us to learn more about our high-performance UV germicidal lamps.

How UV Light Keeps Kitchens Clean

Ultraviolet (UV) is a powerful disinfectant used in many applications to sterilize water, air and surfaces.  High intensity UV lamps eliminate harmful pathogens and break down volatile organic compounds (VOCs).  UV radiation in the wavelength of UVC ultraviolet light is highly effective at eradicating bacteria, viruses, mold, mildew and can even break down grease buildup.  UVC germicidal lamps are being used in many residential, industrial and commercial applications such as restaurants and kitchens. 

UVC germicidal lamps can help to keep restaurants and kitchens clean in many areas such as:

• UV air purification for healthy air in eating areas

• UV surface sterilization over food preparation areas

• UV lamps prevent mold and mildew in walk-in freezers

• UV food irradiation to prevent foodborne illnesses

• UV lamps in kitchen exhaust to prevent grease buildup

Commercial kitchens utilizing UV germicidal lamps in kitchen hood exhaust systems experience cleaner kitchen exhaust without grease buildup which also reduces the risk of kitchen grease fires.  Kitchen hood exhausts with UVC lamps provide low-maintenance, self-cleaning technology to help restaurant owners provide a cleaner and safer kitchen and to meet stringent health department code regulations. 

How UV Lamps Eliminate Grease Buildup

UV lamps eliminate grease buildup through a chemical reaction called photolysis and ozonolysis.  Photolysis, or photodissociation, occurs when photons break down oxygen molecules to oxygen atoms, which combine with remaining oxygen molecules to form ozone. Ozone causes a reaction with the organic compounds found in the grease through a process called ozonolysis. Ozonolysis forms byproducts which are easier to clean and reduces grease deposits and buildup in kitchen hood exhaust and duct systems. 

LightSources Offers UVC Lamps for Commercial Kitchen Sterilization

LightSources and LightTech lead the UV germicidal lamp industry with a wide selection of high-performance UV sterilization lamps.  We offer low pressure mercury lamps, amalgam lamps, medium pressure UV lamps, as well as custom and specialty UV lamp solutions.  Our lighting engineers possess deep technical knowledge of UV radiation and technology, offering custom phosphor blends to meet your specific disinfection requirements.

How Restaurant Owners Benefit from UV Sterilization

Ultraviolet (UV) light has been proven for centuries to eliminate harmful bacteria and viruses and is widely used in many environments and applications for disinfection purposes. UV light sterilization provides overwhelming benefits to many industries, especially restaurants and food preparation facilities. 

Ultraviolet sterilization can be delivered in many ways to protect nearly every single area of a restaurant including food prep countertops, kitchen areas, walk-in freezers, kitchen exhaust hoods, and dining areas. In addition to providing clean surfaces, UV light is used directly on food items in food irradiation which is safe and improves food quality.  UV air purification systems protect patrons from airborne disease and water sterilization ensures clean water free from harmful microorganisms.

Food Irradiation

UV exposure directly to food items is called food irradiation which is completely safe, helps to prevent foodborne illnesses and prolongs food shelf life.  Food irradiation provides many benefits to restaurants such as:

Reduces the risk of foodborne illnesses such as Salmonella, listeria, E. coli and other harmful microorganisms

Extends the shelf life of many food items

Reduces food spoilage

Lowers the risk of importing or exporting pesky insects hidden inside food products

Lessens the need for additives such as antioxidants and preservatives

Lessens the need for pesticides

Reduces early sprouting in potatoes, onions, spices and herbs

UV Surface Sterilization in Restaurants 

UV light sterilization systems provide clean surfaces free from harmful germs, bacteria and viruses simply by emitting UVC light in the right wavelength over countertops and food preparation areas. UV lights can be installed over counters, stoves, food buffets, delis and even walk-in freezers and kitchen hood exhausts.

UV sterilization lamps installed in walk-in freezers help to prevent mold and mildew which can easily occur in cool, damp places. UV lights in kitchen hood exhausts actually help to prevent grease buildup by altering the molecular structure of the grease into components which are more easily cleaned and removed, thus helping to prevent fires.

UV Air Purification Systems in Restaurants

Installing UV air purification systems in HVAC ductwork cleans and sanitizes air circulating through closed in spaces such as restaurant dining areas.  Restaurant owners can provide a healthier dining area for their patrons with clean air, free from airborne contaminants and disease.
