Ozone Light Bulbs with High Quality Quartz Glass

May 31, 2024 by John Andros in Germicidal Lamps

Ozone is naturally produced from ultraviolet light, with ozone light bulbs replicating the UV wavelength needed to produce ozone. When we hear the word ozone, we think of the ozone layer in the atmosphere. This ozone layer is produced from UV light, and filters most of the UV light from the sun.

UV light is emitted at a frequency that is higher than visible light, which is in the range of 400 to 700 nanometer (nm). Ultraviolet light, is beyond the highest frequency of visible light, which is violet, and is emitted from the sun within the range of 100 to 315 nm. Most of this is filtered through the ozone layer in the atmosphere.

UV light emitted in short wavelengths, between 160 and 240 nm, will produce ozone through a process called photolysis of oxygen (O2). This process disrupts the molecule to create valent oxygen atoms that attach to individual oxygen molecules and creates ozone (O3).

Ozone Provides Natural Germicidal Effectiveness

Ultraviolet radiation emitted at 254 nm is proven to deliver highly effective germicidal properties by killing germs and harmful bacteria. UV wavelengths in the range of 185 nm are effective to create ozone, which eliminates contaminants in air, water and surfaces and also acts as a natural oxidizer to eliminate foul odor in the air.

UVC Ozone Light Bulbs

Ozone light bulbs produce UV radiation at less than 220 nm, in the range of 185nm, to effectively decompress the oxygen (O2) in the air which produces ozone (O3). UVC ozone lamps also eliminate volatile organic compounds (VOCs) such as mercaptans, sulfides, and ammonia. One of the greatest advantages of ozone light is that it is carried through the air to places where direct UV exposure cannot reach.

UVC light bulbs emitting 254 nm wavelengths instantly eradicate viruses and bacteria upon exposure, combined with ozone-generating light bulbs, a UV air purification system delivers additional deodorizing properties.

PLS Lights with Custom Options

September 07, 2023 by John Andros in PLS Lights

Compact ultraviolet (UV) lamps are used in many industries and applications in fluorescent-type lamps as well as UVC germicidal, low-pressure mercury lamps. Plug-in lamps with pin sockets come in various sizes and lengths, such as long (PLL) and short (PLS). PLS lights are used in many environments such as accentuating modern architecture, lighting solutions for homes, offices, exterior signs, and security.

Low-pressure mercury compact PLS lights provide germicidal solutions in many applications, killing bacteria, viruses and harmful microorganisms in water, in the air, and on surfaces.

PLS Compact Fluorescent Lamps

Lamp manufacturers offer PLS lamps which are a type of compact fluorescent lamp, also known as CFL bulbs, or energy-saving bulbs. PLS light is becoming more popular and a common lighting choice due to its high performance from a smaller, cost-efficient fluorescent lamp with long life performance. PLS fluorescent lamps are typically available with 2-pin or 4-pin bases with a range of options in emissions and color temperatures from daylight to warm white lighting.

CFL bulbs contain a phosphor coating inside the glass tube which produces UV light when electricity mixes with mercury and argon gases. The fluorescent coating reacts with the UV light to produce visible light, which may start off dim and become brighter.

UVC PLS Light for Germicidal Applications

Ultraviolet radiation in the UVC range, specifically at 254 nm, is proven highly effective at eradicating many types of harmful microorganisms, including viruses, bacteria, mold, mildew, and others. UVC lamps designed to emit 185 nm produce ozone, another proven sterilizer, and oxidizer. There are countless sterilization systems that utilize UVC lamps for cleaner air, water, and surfaces. Many of these sterilization systems require high UVC output in a small space.

UVC PLS lamps provide germicidal effectiveness in a smaller, cost-efficient compact lamp solution.

UVC Virus Killers: Germicidal Lamps and Far UVC

April 14, 2023 by John Andros in Germicidal Lamps

The ongoing COVID-19 pandemic continues to stress the importance of utilizing effective Infection Prevention and Control (IPC) methods, and germicidal lamps are gaining in popularity as UVC virus killers.  Ultraviolet (UV) based technologies are promising IPC tools showing high efficacy in killing many types of beta coronaviruses, including the SARS-CoV-2 virus that causes COVID-19.

As of March 29, 2023, the toll of the global health pandemic as reported by the World Health Organization, WHO, reports 761,402,282 confirmed cases of COVID-19, including 6,887,000 deaths in 229 countries and territories and 102,697,566 confirmed cases of COVID-19 with 1,117,054 deaths in the United States.

UVC Virus Inactivation and Efficacy in Reducing the Spread of Disease

The Federal Drug Administration, FDA, offers additional information for businesses and consumers to learn more about ultraviolet light virus inactivation and its efficacy in reducing the spread of disease. UVC radiation at the correct wavelength has been used for decades for the effective disinfection of air, water, and surfaces and is engineered in UVC germicidal lamps. UV-C light kills bacteria such as tuberculosis and many viruses, including beta coronaviruses.

UV-C Light Kills Viruses MERS, SARS, and SARS-CoV-2

Coronaviruses are a large family of viruses that typically cause mild-to-moderate respiratory infections in humans, although coronaviruses are known to infect both humans and animals. They can often spread in animals but can jump to humans and continue spreading in humans with viral mutations. Coronaviruses are named partly due to the crown-like spiked protrusions on the surface.

Some types of coronaviruses may cause illnesses like the common cold, although severe acute respiratory syndrome viruses (SARS-CoV) can be severe, such as the fatal outbreak of SARS in 2002 and Middle East Respiratory Syndrome coronavirus (MERS-CoV) in 2012. SARS-CoV-2 is another severe acute respiratory syndrome virus that causes COVID-19.

Ultraviolet light virus inactivation is highly effective at eliminating the threat of coronaviruses, including the SARS-CoV-2 virus, when administered at the proper wavelength and dosage. According to a scientific report, UV-C irradiation is highly effective in inactivating SARS-CoV-2 replication; the response of UV virus inactivation depends on both the virus concentration and the UVC dose. The results of this study and many others show that the SARS-CoV-2 is extremely sensitive to UVC light.

UVC Light Kill Viruses And Other Harmful Pathogens

According to a study published in 2020 and reported by Biological Consulting Services, UVC virus inactivation was determined against various harmful pathogens with results including:

  • Influenza A H1N1 – 99.999% reduction

  • SARS-CoV-2 virus – 99.999% reduction

  • Polio Virus LSc 1 – 99.99% reduction

  • Methicillin Resistant Staphylococcus Aureus (MRSA) – 99.99 reduction

  • Salmonella species, 6 variations – 99.99% reduction

UV virus elimination is very effective when using the right type of UVC germicidal lamps and the proper dosage, and environment such as line of sight disinfection on a surface not contaminated with dirt that can affect UV inactivation results. This is why ultraviolet light virus disinfection is recommended in addition to manual cleaning practices for maximum effectiveness.

UVC Virus Disinfection in Air, Water, and Surfaces

UVC germicidal lamps are typically designed to emit wavelengths at precisely 254 nm, proven to be highly effective at penetrating the DNA of microorganisms to render them harmless. Far UVC lamps are gaining in popularity and showing high germicidal efficacy while being safer to operate in the presence of humans. Standard germicidal UVC lamps should operate in non-occupied spaces and can be found in upper room ultraviolet germicidal irradiation (UVGI) systems, HVAC systems, and other disinfection devices like UVC robots programmed to run through hospital hallways or patient rooms that are unoccupied.

Not all UVC germicidal lamps are created equal, and it is important to work with an experienced ultraviolet lamp designer to ensure effective germicidal properties.
