UV HVAC Systems for Hospitals and Homes


Ultraviolet light is a powerful disinfectant, sterilizing surfaces, water and air in many environments.  The power of UVC radiation was discovered decades ago and UVC lamps are now found in many sterilization applications, providing quick, effective and cost-efficient sterilization solutions.  The ability for UV light to kill pathogens in air and water was proven scientifically early in the 20th century.  UV lamps have been used in air treatment systems in hospitals since the 1930’s to prevent the spread of diseases including tuberculosis and measles. 

UVC Lamps Kill Many Viruses and Bacteria

UVC lamps replicate the powerful UV electromagnetic radiation from the sun, proven to eliminate harmful viruses, bacteria and pathogens in air and surface sterilization systems.  UVC germicidal lamps are proven to be effective against many types of viruses including influenza (flu), rhinoviruses (common cold), severe acute respiratory syndrome (SARS) and the novel coronavirus (COVID-19).   UV light also eliminates bacteria such as many variations of Streptococcus including Staphylococcus aureus (Staph infection). 

UVC lamps, when properly installed in HVAC systems, are known to prevent the spread of airborne illnesses by destroying viruses on contact.  UV HVAC systems are also known as ultraviolet germicidal irradiation (UVGI) systems and target air contaminants like viruses, bacteria and mold spores.  UV light has the ability to penetrate the DNA of these living organisms and render them unable to replicate which leaves them harmless. 

Commercial and Residential Benefits of UV Lamps in HVAC Systems 

Hospitals and many commercial and industrial applications have been using UV air sterilization systems for decades to disinfect potentially dangerous environments.  UV HVAC systems used in hospitals help to prevent the spread of airborne illnesses in patient rooms, operating rooms and common areas.  UV lamps can be installed in the main HVAC unit aimed at the coils to prevent the spread of contaminants through your heating and cooling system as well as in air ducts.  Stand alone units can be placed in patient bathrooms for further protection in areas known to spread bacteria and viruses. 

UV HVAC systems are becoming more popular in residential homes as many people become aware of the benefits and the ease in which you can disinfect the air in your home.  This is very beneficial to people with compromised immune systems or underlying health conditions, especially respiratory illnesses like asthma.  

UVC Lamps for HVAC Units

Using the proper UVC germicidal lamps with proper installation is key to achieve maximum benefit.  LightSources understands UVC radiation and how to harness the most effective, germ-killing wavelength for maximum germicidal effectiveness.  We offer a wide range of UV germicidal lamps including medium output lamps, high output lamps patented amalgam technology and custom, specialty designed lamps.  LightSources is a valuable supplier of high quality lamps, bases and sockets to OEMs worldwide.

Do UV Germicidal Lamps Really Work?


An ultraviolet (UV) germicidal lamp produces ultraviolet radiation with electricity. UV radiation is proven to eliminate harmful germs, bacteria, viruses and microorganisms within seconds of exposure. UV radiation emitted at 254 nm is the most effective wavelength which instantly penetrates the DNA of these harmful cells and renders them unable to replicate. Viruses and germs that cannot multiplied to infectious levels are considered dead and harmless.

Low-pressure Mercury discharge lamps are similar in construction to fluorescent lamps although the inner lamp wall does not have a phosphor coating which allows the right amount of UV radiation to filter through.  Low-pressure Mercury germicidal lamps convert up to 40% of electricity into UV radiation.  

The lamp body of a UV germicidal lamp is made with soft glass, quartz or pure fused quartz. Lamp bodies constructed with pure fused quartz of 185 nm as well as 254 nm emissions with VH (very high) glass.  UV germicidal lamps that transmit 185 nm of UV radiation produce ozone which is a known oxidizer and sanitizer. Ozone effectively eliminates foul odors in the air and can be transmitted through the air to reach places direct UV exposure cannot reach.

UV lamps manufactured with quartz and titanium block out 185 nm emissions to transmit 254 nm of UVC radiation only. UVC lamps engineered with L glass is soft glass which transmits 254 nm UV radiation for germicidal effectiveness.  Electrodes located at each lamp and connect an external current source to the Mercury gas discharge device. 

The germicidal lamp body is filled with either pure argon gas or a mixture of rare gasses including neon and argon. A small amount of mercury produces the necessary UVC radiation.  UV germicidal lamps really do work although it is best to speak with a reputable UV lamp manufacturer to be sure that you achieve the right emissions of UV radiation for your application.

LightSources has constructed patented UVC germicidal lamps which outlast and outperform comparable products with energy efficiency and safety features included.  You can find our germicidal lamps in air purification systems and water sterilization applications worldwide.

High Performance UV Lamps for Ballast Water Treatment Systems

post 110

UVC radiation is a highly effective, proven method of sterilizing and purifying water, air and surfaces.  With the new Ballast Water Treatment Convention, BWTC, that went into full effect last September of 2017, shipping companies are required to maintain an effective system on board their vessel.  Contaminated ballast water is considered to be one of the top 5 threats to the sustainability of the planet’s oceans, as foreign marine organisms are picked up in one port and released in another.

This has wreaked havoc on the fishing industry in many shipping ports and threatened the safety of human life in cases where foreign invaders take over without their natural predators.  Jellyfish have been known to multiply to uncontrollable levels while mussels attach to structures such as dams and bridges causing damage by upsetting the natural ecosystem. UV lamps utilized in ballast water sterilization systems solves this problem with a highly effective and simple to maintain system.

UV Lamps with Powerful Water Sterilization Effects

Ultraviolet technology is proven to sterilize water by instantly killing bacteria, viruses and microorganisms naked to the human eye.  With powerful wavelengths emitted at 254 nanometer, nm, the DNA of these living organisms is immediately altered making them unable to replicate rendering them harmless.
