UVC Induction Technology
An Induction Lamp is surprisingly similar to a fluorescent lamp. It contains solid metals in a gas fill inside the bulb, which becomes excited when electricity is applied emitting UVC. Fluorescent lamps, however, use electrodes inside the bulb to strike the arc and maintain the flow of current - each time the arc is struck, the electrodes degrade a little causing the lamp to flicker and then fail. Induction Lamps differ from fluorescent lamps in that they do not use internal electrodes, but use a high-frequency generator with a power coupler to produce a magnetic field to excite the gas fill. Induction lamps are more powerful, up to 50% more efficient and last 5-7 times longer.
Why is UVC Induction Lighting Effective?
Induction UVC, a type of Germicidal lamp works by breaking down certain chemical bonds and scrambling the structure of DNA, RNA and protein in viruses, bacteria and protozoa causing these microorganisms to be unable to multiply and leads to their inactivation and ability to be infectious.
How is germicidal effectiveness determined?
Power intensity, wavelength and exposure duration are typically used to determine germicidal effectiveness. For instance, in water there may be multiple germs with different optimal absorption wavelengths. For any given wavelength of germicidal UV light, the power and duration of exposure would need to be calculated in order to achieve the desired level of sanitization of the structure of DNA, RNA and protein in viruses, bacteria and protozoa causing these microorganisms to be unable to multiply and leads to their inactivation and ability to be infectious.

- According to a Tulane University study published in Emerging Infectious Diseases, coronavirus can remain infective in aerosol for up to 16 hours. UVC Purelight360™ is able to sanitize surfaces in rooms up to 576 sq ft. within 5-20 minutes.
- According to the US Department of Energy many induction lighting units have an extremely long life of up to 100,000 hours. To put this in perspective, an induction lighting system lasting 100,000 hours will last more than 11 years in continuous 24/7 operation, and 25 years if operated 10 hours a day.
- Unlike other UVC carts that use fluorescent lamps that contain hazardous liquid mercury, UVC Purelight 360™ induction lamps use mercury in a solid form combined with a metal so that it only turns into a gas when excited by electricity and it returns to its solid form when cooled making it safer in the event of breakage. According to the World Health Organization, exposure to mercury – even small amounts – may cause serious health problems, and is a threat to the development of the child in utero and early in life.
- UVC Purelight360™ does not use Ozone. According to the Environmental Protection Agency, when inhaled, ozone can damage the lungs. Relatively low amounts of ozone can cause chest pain, coughing, shortness of breath, and throat irritation. It may also worsen chronic respiratory diseases such as asthma as well as compromise the ability of the body to fight respiratory infections.
- UVC Purelight 360™ lamps are produced with doped quartz glass, which blocks the transmission of the 185nm ozone-producing wavelength. The doped quartz glass allows the 253.7nm UVC radiation to pass through, but it blocks the 185nm wavelength from escaping. Therefore, Purelight 360™ germicidal lamps with doped glass CANNOT produce ozone. According to the Environmental Protection Agency, many UV germicidal lamps are not made with doped quartz glass and produce ozone which when inhaled can damage the lungs. Relatively low amounts of ozone can cause chest pain, coughing, shortness of breath, and throat irritation.
- According to the Environmental Protection Agency, it is not recommended to use fumigation or wide-area spraying to control COVID-19.
- Furthermore, according to the World Health Organization, in indoor spaces, routine application of sanitizers to environmental surfaces via spraying or fogging (also known as fumigation or misting) is not recommended. Spraying environmental surfaces in both health care and non-healthcare settings (e.g. patient households) with sanitizers will not be effective and may pose harm to individuals.
