  COVID-19 (Coronavirus Disease 2019) is the disease caused by the novel coronavirus, SARS-CoV-2, which is the cause of a viral outbreak that led to a devastating global pandemic. Public health systems and economies worldwide have been ravaged by this virus and many people are asking the question, “Does UV light kill Covid?”. As of December 31, 2021, the pandemic is experiencing a surge with the new Omicron variant and a total death toll of 5,439,895 globally, with more than 825,816 deaths in the United States.   We put together a compilation of several studies showing the effectiveness of UV light for COVID, although according to the Food and Drug Administration, FDA, as of February 2021 there is still a limited amount of published data on the required dose, wavelength, and duration of UV light necessary to kill the SARS-CoV-2 virus that causes COVID-19.   Types of UVC Lamps Effective in Killing Covid   Ultraviolet (UV) light is a type of UV radiation f...

  The world has challenged many technological changes many times over. These changes remain to persist and one such field that has experienced tremendous number of modifications is the lighting market. Energy efficient lighting is in high mandate these days principally because standard components which were used for years in numerous commercial luminaries are being fine-tuned as well as polished in order to encounter the demands of energy conscious generations. It is really shocking to see the exceptional outcomes of these energy saving lightings. Lamp and UV Lamp Ballasts are the two most significant components that form a part of commercial lighting fixtures. Many high-end applications such as 250W or 400W metal halide lamps mainly depends on engineering requirements, ceiling height, as well as fixing space. Due to the efficiency, it provides, these high lumen output lanterns have been the biggest strength of the energy efficient lighting industry for more than 50 years till dat...

  UV Electronic Ballast , also known as the controller gear, is found in most of the electric circuits to possess a check on the allowable limit for supply of electric current to the circuits. They performance more like resistors and are used in neon bulbs, UV Lamp and LEDs.   The uses of UV Electronic Ballast for high power installations are not recommended as the resistance varies greatly in complexity and depends much upon the capacitive action of inductors and capacitors. Most of the ballasts are remote controlled and come with digital technology to be used in fluorescent lamps. In general, the ballasts assistance in stabilizing the overall current load. With negative supply of current flow, the ballasts draw power from a high voltage supply and distribute it at an appropriate level for the circuit to be stabilized. By deriving positive resistance, the ballasts limit the supply of current and a good example would be the gas discharge lamp.   The concept is mo...

  Start Breathing Easier in Your Home There are numerouskinds of UV lights on the bazaar today, especially with the current concerns about living healthy and germ-free. However, it's hard to know which ones you can confidence with your family's well-being and which ones are fake and ineffective. What are UV lights? Ultraviolet (UV) light is a constituent of the electromagnetic spectrum that decreases in the region between visible light and X-Rays. UV light includes the wavelength range of 100 nm to 400 nm and can be additional subdivided and categorized into four separate regions: 100 nm to 200 nm: Far UV or vacuum UV (these wavelengths only propagate in a vacuum) 200 nm to 280 nm: UVC – valuable for disinfection and sensing 280 nm to 315 nm: UVB – valuable for curing, tanning and medical applications 315 nm to 400 nm: UVA (or “near UV”) – valuable for printing, curing, lithography, sensing and medical applications How does UVC disinfection w...

  Ultraviolet (UV) light was first discovered in the mid-20th century, introducing a new way for people to eliminate viruses and bacteria. Although UV technology has risen to prominence in recent years, especially during the current COVID-19 pandemic, the majority of the general public does not fully understand exactly how UV lighting helps kill viruses and bacteria. The following article will shed light (pun intended) on how UV light works, what UV-C products and equipment are available on the market, and the precautions that need to be taken to avoid exposure to human skin. Types of UV light UV light is divided into several ranges: UV-A, UV-B, UV-C (close to the visible light range) and Vacuum-UV (close to the x-ray range). The UV-C light range is the only one able to destroy germs. It is found in UV water purifiers, used in fish tanks, and in portable UV light sanitizers designed to destroy germs that may exist on your tech gadgets and other regular household items. UV-C l...

  Traditional disinfection methods have been used for centuries – but are they good enough? The truth is that even the most rigorous cleaning with hot water, bleach, and disinfectants can miss harmful germs and bacteria. In the worst-case scenario, those things may cause illness or even death. On the other hand, UV light disinfection uses ultraviolet technology to kill all germs and bacteria more quickly and is a great supplement for other methods. Some businesses are reluctant to try it, but at Violet Defense, we know that the benefits far outweigh the expense of making the switch. Here are the top six benefits of using UV light for disinfection. Benefit #1: UV Light Disinfection is Non-Toxic Arguably, the most important benefit of UV light disinfection is that it’s non-toxic. Unlike harsh chemicals that are sometimes used in cleaning and sanitization products, UV light is environmentally friendly. UV light disinfection is a physical process, not a chemical one. UV light ...

  Most of us know that UV light can kill viruses and bacteria with germicidal properties, but do you know how it works and the many benefits of hospital UV light disinfection? Ultraviolet (UV) light is electromagnetic radiation emitted in various wavelengths, either UVA, UVB or UVC, with short-wave UVC having the most powerful, germ-killing properties. UVC light emitted at 254 nanometer (nm) is proven to destroy harmful pathogens and microorganisms with high efficacy. Disinfection in hospitals has always been of great concern, although recent events with hospitals across the country reaching near capacity makes cleanliness and disinfection even more important. Hospital acquired infections (HAIs) are infections that occur within 48 hours of hospital admission, within three days after discharge or up to 30 days following an operation. The Center for Disease Control, CDC, estimates that 1 in 31 patients in U.S. hospitals contract an HAI, many caused by serious antibiotic resist...
