How to Select a Light Therapy Box for Seasonal Depression

According to the American Academy of Family Physicians, seasonal depression that occurs during fall and winter months due to a lack of sunlight affects approximately 4 to 6% of people. Seasonal Affective Disorder, also called SAD, can affect another 10 to 20% of people and is four times more likely to occur in women than in men. SAD is also more common in northern locations such as Washington state as opposed to a more southern and sunny state like Florida

Light therapy with a medical phototherapy lamp, also called a light therapy box, can help to alleviate some symptoms of seasonal depression although can be more effective when combined with additional treatments such as psychotherapy and antidepressant medication

How Light Therapy Treatment for Depression Work

Light therapy boxes mimic outdoor sunlight, which is believed to cause a chemical change in the brain that eases symptoms of seasonal depression and lifts your mood. Generally, a light therapy box should emit as little UV light as possible and should provide an exposure to 10,000 lux of light

Recommendations for using light therapy include:

• Using for about 20 to 30 minutes within the first hour of waking up

• Have your eyes open but do not look directly at the light

• Keep the lamp a distance of 16 to 24 inches away from your face

Light therapy boxes are designed with special medical phototherapy lamps. Some people might think that a tanning bed provides the same benefit although this is not true. Tanning bed lamps are quite different and are known to increase the risk of skin cancer. While light therapy for seasonal depression is not regulated by the Food and Drug Administration, FDA, they are designed to be safe and effective.

Your doctor can help to recommend a specific type of light therapy box, although you can buy one without a prescription and most health insurance plans will not cover the cost.

Considerations When Choosing a Light Therapy Box

It is best to speak with your doctor about your symptoms and for help in choosing the right type of light therapy treatment. For people with bipolar disorder, too much exposure could induce manic symptoms. People with eye conditions such as cataracts, glaucoma, or eye damage from diabetes should speak with their eye doctor before beginning phototherapy

When choosing a light therapy box make sure that it is specifically designed to treat seasonal depression. Many medical phototherapy lamps are designed to treat skin disorders such as acne, eczema, psoriasis, and vitiligo. Medical therapy lamps designed for skin conditions are not the same as lamps designed for depression.  Tanning lamps and UVC germicidal lamps are also not designed with the same wavelength and can cause harm instead of benefits if used incorrectly.

UV Lamps in Your Furnace Disinfect the Air

Ultraviolet (UV) light has very distinct properties and when emitted in the short wave UVC range, it is very effective at killing germs.  UV light is emitted in different wavelengths known as UVA, UVB and UVC.  UVA and UVB reach the earth and are what causes the common sunburn, whereas UVC energy is absorbed by the ozone layer.  UV lamp engineers recreate UVC energy in powerful germ-killing lamps that quickly eliminate harmful pathogens to sterilize surfaces and the air in mere seconds. 

How Do UVC Lamps Sterilize Air?

UVC lamps sterilize the air by quickly eliminating harmful germs including bacteria and viruses.  UV wavelengths are measured in nanometers (nm) and UV light at the 254 nm range is proven very effective at destroying germs. UVC electromagnetic energy penetrates the DNA of these cells and renders them unable to replicate.  A cell that cannot replicate is considered harmless. 

UVC Lamps in Furnaces

UVC lamps are the key to disinfection in surface, water, and air purification systems.  UVC disinfection lamps can be mounted in furnaces and HVAC systems to eliminate the growth of mold or mildew inside the unit itself and to sterilize the air as it passes through the lamp’s wavelengths.  UVC germicidal lamps in furnaces help to prevent the spread of airborne disease while also improving equipment performance.  Mold and mildew tend to build up in damp, dark places like the inside of a furnace, UV lamps improve equipment performance for longer lasting use with less maintenance required. 

According to this article by the National Institutes of Health, UVC lamps effectively reduce contamination of fungi in HVAC air handling systems. 

UVC Lamps for Furnaces

LightSources offers germicidal UVC lamps for air purification when installed in furnaces and HVAC systems.  UVC germicidal lamps designed to emit 185 nm produce ozone, another type of disinfection lamp that can travel in the air with an oxidative effect to eliminate foul odors. UV lamps should be installed by a professional for furnace and HVAC disinfection. 

LightSources offers UVC germicidal lamp solutions to OEMs of all sizes.  We provide a wide selection of high-tech, high-quality germicidal lamps and offer custom designed solutions to meet the specifications of your air purification system.  Contact us to speak with an engineer about UV lamps for furnace disinfection applications. 

UVC Lamps Help Hospitals with Effective Sterilization

Hospitals provide critical care to people with serious illness whether emergency treatment, diagnostic services, or ongoing care for chronic illness.  Due to the nature of the typical patient, hospitals must be vigilant in sterilizing surfaces and protecting patients from infection.  The Centers for Disease Control and Prevention (CDC) reports that on any given day an estimated one out of every 31 patients in the U.S. contract a Healthcare Acquired Infection (HAI) from their stay in a hospital. 

Patients who enter a room following a patient that had an infection such as the influenza virus and even drug resistant superbugs like MRSA run a high risk of contracting an HAI.  

UV Lamps in HVAC and Air Purification Systems

Many illnesses can be transmitted through airborne particles such as tuberculosis and many influenza viruses.  UVC lamps in air purification systems play an important role in sterilizing the air making it healthier for patients and staff.  UV lamps can be installed in upper room UVGI (ultraviolet germicidal irradiation) systems or directly into HVAC systems for automatic purification.  Some systems can be designed to come on when a patient leaves the restroom, for example, while others are always working behind the scenes in furnaces and AC units.  

UVC Germicidal Lamps for Surface Sterilization

UVC lamps provide highly effective sterilization in air, water, and surface sterilization systems.  There are many ways to reap the benefits of surface sterilization with systems like UVC robots and UVC lamps that directly disinfect critical areas like surgical rooms.  UVC lamps are also used to disinfect and keep surgical equipment clean.  UVC robots are being deployed in hospitals as well as other public places to work autonomously with high rates of efficacy.

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.

UVC Robots Enter the Battle Against COVID

COVID-19 and its variants have been ravaging the globe for more than a year now, and hopefully the war is winding to its conclusion, with increased vaccinations and increasingly knowledgeable diligence by citizens to help curb the spread of infection.

There is another significant weapon in the fight against COVID: UVC germicidal lamp robots. Several scientific studies have confirmed UVC light’s effectiveness in killing the SARS-CoV-2 virus that causes COVID-19, and businesses, particularly hospitals, are increasingly deploying robots to aid in sterilization of air and surfaces. Many hospitals across the United States are using UV light robots as an added layer of protection against the spread of the pernicious virus. 

Human resources and personal protective equipment are sometimes pressed to exhaustion during surges in COVID-19 cases. That is when UV robots can provide valuable resources with additional sterilization.  UVC robots can be programmed to enter a hospital room after the manual cleaning is complete and finish the job by killing bacteria and viruses missed by overworked staff. The robots can work tirelessly and even navigate back to their charging ports when sensing depletion of their battery power.

UVC germicidal lamps have been proven effective in eliminating causes all along the spectrum of coronavirus diseases, including Middle East respiratory syndrome (MERS) and severe acute respiratory syndrome (SARS).  

UVC Robots Valuable in Many Settings

The value of UVC robots does not end with battling coronaviruses. They also reduce risk of the most common Healthcare Associated Infections (HAIs) generated from superbugs that invade hospital environments. UVC robots are increasingly employed outside the medical field where masses gather in concentrated locations, such as airports, train stations, shopping malls, and public shelters. 

As with any UVC sterilization system, the type of germicidal UV lamps is key to reaching maximum disinfection. LightSources is a leader among UV lamp manufacturers, with decades of experience, a global presence, and the leading high-tech lamp engineers in the industry.

Many Advantages of UV Light Disinfection Robots

Robots have been used in many areas of the medical field for decades, such as the Da Vinci robot that helps with surgeries and robots that roam from patient room to patient room with tablets allowing for tele-visits with your doctor. Robots assist with many other roles in the medical field such as disinfection robots equipped with ultraviolet (UV) lamps used to help sterilize surfaces.  

Disinfection robots are not a new idea, they have been around for a while although have gained increased attention amidst the coronavirus pandemic.  UV light disinfection is used in many industries to sterilize surfaces, air and water and is proven effective in the healthcare industry to help prevent the spread of infection.  Hospitals must be diligent in cleaning and sterilizing patient rooms as hospital acquired infections (HAIs) are a serious concern for patients and staff. 

The most commonly transmitted HAIs are from viruses and bacteria resistant to antibiotics and are also referred to as superbugs. Some of the most common superbugs include methicillin-resistant Staphylococcus aureus (MRSA), Vancomycin-resistant enterococci (VRE), and Clostridium difficile (C.diff).  It is estimated by the CDC that one in every 31 hospital patients will contract an HAI on any given day.  This puts patients and staff at risk of contracting a serious illness that causes pain, suffering and even death. 

UV Disinfection Robots Help to Prevent HAIs

A study by the National Institutes of Health, Application of Service Robots for Disinfection in Medical Institutions published in 2017 shows that ultraviolet light robots significantly reduced the burden of MRSA on patient room surfaces.  This was true for patients known to have had a MRSA infection.  UV light sterilization devices including UV light robots used in conjunction with manual cleaning and sterilization efforts are highly effective at reducing the amount of harmful pathogens on surfaces. 

UV light robots provide effective disinfection properties and many additional benefits such as automation, robots can be programmed to shut down in the presence of people and to find their way back to their charging station.  Robots are an investment that pays off with increased sterilization and no labor expenses.  The types of UVC germicidal lamps used in UVC robots are crucial to achieve maximum sterilization effectiveness.

Does UV Light Kill Covid in Water, Surfaces, and in Air?

Ultraviolet (UV) UV light emitted specifically in the UVC range is proven to be highly effective at killing many germs including tough bacteria and viruses. UVC radiation emitted at specifically 254 nm wavelengths is the most effective to inactivate viruses and bacteria by penetrating the cells of these microorganisms and rendering them unable to replicate. UVC wavelengths emitted in the range of 207 - 222 nm is referred to as far UVC light, which is also very effective at sterilization while not quite as harmful to human skin and eyes. 

UV Sterilization in Water

UVC germicidal lamps are used in many water sterilization applications such as wastewater treatment plants, pool and spa and many other water disinfection applications. Germicidal UV lamps have been proven to eliminate many harmful bacteria that even chlorine does not kill, like Cryptosporidium and Giardia. UV light is also proven to kill harmful beta coronaviruses, like Middle East Respiratory Syndrome (MERS) and Severe Acute Respiratory Syndrome (SARS).  The SARS-CoV-2 virus that causes COVID-19 is in the same beta coronavirus family as MERS and SARS and UV light is also effective at eliminating the SARS-CoV-2 virus, as shown in this recent study. 

UV Light Kills SARS CoV-2 Virus on Surfaces

UVC lamps are highly effective at eliminating harmful pathogens on surfaces and are in wide use in many applications such as hospitals, schools, and laboratories. Surfaces should be clean and indirect exposure of UV radiation for maximum efficacy, which is why many hospitals follow manual cleaning procedures with a roaming UVC robot. This is an effective practice to significantly increase the safety of patients in hospital rooms and staff. 

UVC Lamps Kill Covid in the Air

The SARS-CoV-2 virus that causes COVID-19 is known to spread the airborne particles which is one of the most common modes of transmission and infection. UVC air purification systems kill viruses and bacteria as they circulate through the air in your home or office, protecting people from airborne disease. UV lamps in HVAC and central AC units provide automatic 24/7 protection by killing viruses that pass through air handling units (AHUs) and protect your equipment by preventing the buildup of mold and fungi.

UVC germicidal lamps are highly effective at eliminating bacteria and viruses, including beta coronaviruses and the SARS-CoV-2 virus that causes COVID-19.

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.

Are UVC Robots Effective in Killing the SARS CoV-2 Virus?

One full year into the COVID-19 pandemic and we are seeing the light at the end of the tunnel, with widespread vaccinations and people everywhere doing what they can to reduce the spread of infection. With several studies documenting the effectiveness of UVC germicidal lamps to kill the SARS-CoV-2 virus that causes COVID-19, businesses are taking notice and investing in UV disinfection systems to protect their staff and the public. In addition to typical UV light water, surface and air sterilization systems, UVC robots are in high demand. 

Many hospitals across the country have invested in UV light robots to provide an added layer of protection against spreading disease. In spite of the most meticulous manual cleaning regimen, hospital staff can be pushed to the limit and operating with limited personal protective equipment. A UVC robot can be programmed to enter a hospital room after a manual cleaning process, and effectively kill bacteria and viruses often time missed even with the most diligent attempt at disinfection. UVC robots aid weary hospital staff without being on the payroll or needing a break, they simply make their way back to the charging station when required and deliver powerful germ killing UVC light to eliminate viruses and bacteria.

UVC Robots Proven Effective

Several studies have now been conducted which verify the effectiveness of UVC germicidal lamps to kill the SARS-CoV-2 virus, which is a member of the beta coronavirus family similar to MERS and SARS.  Middle East respiratory syndrome (MERS) and Severe Acute Respiratory Syndrome (SARS) are in the same coronavirus family and have been known to be effectively eliminated by UVC radiation.  UVC light effectively inactivates these viruses as shown in a recent study by PURPLESUN which shows dosage and exposure time required to inactivate various types of coronaviruses as well as exposure time required to effectively kill drug-resistant bacteria.

Not only will UVC robots help hospitals to prevent the spread of COVID-19, they also continue to reduce risk of common health care associated infections (HAIs) from superbugs often found in hospitals. With UV light sterilization gaining in popularity, UVC robots are now seen outside of the medical field in places such as airports, train stations, shopping malls and public shelters.

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.
