UV Warning
WARNING: ULTRAVIOLET LIGHT IS HARMFUL TO EYES AND SKIN. DO NOT STARE DIRECTLY INTO THE
ULTRAVIOLET BEAM WITHOUT WEARING PROTECTIVE GEAR TO PROTECT EYES FROM LONG TERM DAMAGE.
UNPLUG LAMP BEFORE SERVICING.
The Larson Electronics IND-CDL-SQ-10-FUVC-MP-1L-V1 Far-UV Recessed Square Light disinfects 99% of
viruses, bacteria, mold and spores from ceilings in occupied areas. This eye and skin safe disinfection unit uses
one 10-watt microplasma board that emits far-UV 222 nm germicidal light. Featuring an expected lifespan of 6,000+
hours, the unit is compatible with 120-277V AC, 50/60Hz.

fungi and other deadly microbes. Moreover, far-UV light is considered to be eye and skin safe for humans, as 222 nm UV rays cannot penetrate the skin to levels that cause burns or severe damage. A 2018 study published in the US National Library of Medicine National Institutes of Health has proven that chronic irradiation with 222 nm far-UV lamps does not cause epidermal lesions often associated with exposure to traditional 254 nm UV-C rays. -

During sanitation, UV-C light in large, concentrated doses causes RNA and DNA mutations in microbes during absorption. The ideal wavelength for peak absorptivity occurs at wavelengths of 254nm to 262nm (for traditional UV sanitation) and 222 nm. According to a 2012 study published in US National Library of Medicine National Institutes of Health, UV-C treatment has the following devastating effects on microbes: “The light-induced damage to the DNA and RNA of a microorganism often results from the... -

higher UV absorption than conventional 254 nm. The possibility of photo-reactivation is also decreased due to the high energy of 222 nm. Spectral-selective excimer lamps are the artificial light source of choice when generating far-UV 222 nm light for sanitation. The term “excimer” is short for excited dimer, which refers to the presence of dimeric molecules with nanosecond-lifespans in an excited state. -

period to mice. In both tests (skin samples and chronic exposure), traditional UV sanitation lights in the 254 nm range were tested using the same types of samples for comparison. After exposure to 222 nm light, the skin samples in the first test did not produce lesions or display signs of irritation, as well as did not generate damaging levels of cyclobutane pyrimidine dimers (CPD) and pyrimidine-pyrimidone 6-4 photoproducts (6-4PP). -

type A2 biosafety cabinet housed the chamber with the samples. The results showed that the 222 nm light eliminated more than 95 percent of the aerosolized H1N1 influenza virus. A 2020 study (pre-print; under review) aimed to determine the effectiveness of far-UV 222 nm light on human coronaviruses from subgroups alpha (HCoV-229E) and beta (HCoV-OC43). -

manufactured using doped fused quartz (can produce 185 nm ozone) or soda-lime glass (cannot produce 185 nm ozone) so that UV 254 nm bands from the mercury arc can pass through the material. Quartz-based UV-C lights increase electrical efficiency and require a short warm-up time of 30 seconds to reach full output. -

from the study concluded that such devices, which include systems used to administer UV-C light or radiation, can improve survival rate of individuals. At the front lines, UV-C light is proven to be effective in sanitizing N95 filtering facepiece respirators (N95 FFRs). Medical staff must deal with the shortage in N95 respirators and other protective devices by disinfecting the equipment and reusing them. -
