Specialty and Architectural Lighting — Ultraviolet Light

Since the COVID-19 outbreak, there has been a proliferation of ultraviolet UVC products. While there are many good companies out there using high-quality products and effective designs, there has also been a flood of low-quality junk and even completely fake UVC devices. As of this writing, there are few official standards for UVC germicidal lighting products, either bulbs or fixtures. Many companies have been manufacturing specialty ultraviolet lamps, ballasts, and luminaires for decades. However, it...

Over the last few months, matching UV bulbs to ballasts has become increasingly difficult. While specialized ultraviolet ballasts have been bought up, equipment manufacturers have become more creative in finding compatible fluorescent ballasts for the UVC bulbs. But will these always work? And how can you find a compatible ballast?

When UV-C fixtures or handheld devices are used to sanitize surfaces and objects, it may be useful to determine the UV dose applied and comparing that to tables of dose requirements for deactivating microorganisms. Measure UV Intensity To get accurate dose data you need to start with a UV-C detector. The detector needs to display an intensity reading measured in microwatts per square centimeter (μW/cm² ). The Zenith detector is one example of a UV-C...

Should you buy that cheap UVC LED bulb on Amazon or eBay? It's a 500W equivalent and screws into your table lamp. Great deal, right? Unfortunately, it's starting to come out that these bulbs are fake. Instead of outputting UVC light, many are likely UVA blacklights, and manufacturers are exploiting coronavirus fears to sell fakes to consumers and medical professionals.

Large naval vessels are compact environments where microbes can thrive, circulating through the ventilation system. Ultraviolet germicidal irradiation (UVC) lighting systems can reduce incidence of harmful bacteria and viruses, and mitigate the risk of respiratory and airborne illnesses spreading throughout a navy vessel, cruise ship, yacht, or smaller boat.

Sometime in the future, whether it be a month, six months, or another year, offices and commercial buildings will reopen to employees and the public. One big change, though, is that both workers and visitors will expect a higher level of cleanliness for any building they walk into. Ultraviolet UVC lighting has been in use in commercial buildings for decades, but concern is growing over reducing airborne pathogens. Building owners, managers, and maintenance departments can...

One of the concerns about reopening the economy is that, if large gatherings are allowed again, the COVID-19 strain of coronavirus may spread rapidly. This is a legitimate concern as historical outbreaks of serious or deadly diseases have occurred in places of large assembly where one person exposed an entire population. But with the greater awareness of sanitizing air and surfaces, UVC lighting systems can provide some protection and mitigate the risks of allowing public...

Since the COVID-19 outbreak, hospitals and medical professionals have begun using ultraviolet germicidal UVC light more than ever before. Learn about the options the medical industry has for disinfecting air, stopping the spread of germs, and disinfecting patient rooms with ultraviolet light.

One small positive of the coronavirus outbreak and response is the increasing awareness of people of the effects of ultraviolet UVC germicidal light on viruses, bacteria, mold, and fungi. This article examines the harmful microorganisms commonly found in homes, as well as UVC solutions for sanitizing air and surfaces.

Everyday, it seems like the news coming out of China gets worse and worse. Far from the coronavirus being a small outbreak, there are indications that it won't be over soon and is worse than reported. But the ramifications of coronavirus reach far beyond just the illness and deaths the outbreak is causing, which are tragic and heartbreaking enough. Parts of China are simply shut down with quarantines or people staying home, meaning manufacturing is...
