THEORY
7.1.
Visual light is part of the electromagnetic spectrum that can be detected by the
human eye, typically having wavelengths between 400nm to 700nm.
7.2.
UV radiation is usually specified as having wavelengths from 10nm to 400nm.
7.3.
UVC radiation is identified as having wavelengths between 100nm and 280nm,
and it is MUV (Middle Ultraviolet) having wavelengths between 200nm and
300nm that is considered germicidal.
7.4.
UVC light can be absorbed by RNA and DNA causing damage to these
molecules, such as in the formation of a thymine or cytosine dimers, which
distort the molecule and prevent proper functionality.
7.5.
The efficacy of UVC radiation is well documented in the literature as a means
to inhibit microbial viability and inactivation of COVID-19 (See References,
Section 14).
7.5.1. Recent studies indicate that an irradiance dosage of
≥ 3.6mW/cm
2
of
UVC
(260
–285nm)
on contact surfaces is sufficient to
inactivate or “kill” the
SARS-CoV-2 virus.

PRODUCT DESCRIPTION
8.1.
The WT-Germ Killer 8910UVC BODYLight is a flexible battery powered or
cord connected germicidal UVC LED Light.
8.2.
The UVC BODYLight and all components are ETL Certified to be Explosion
Proof compliant for use in the following hazardous (classified) location
atmospheres and water environmental conditions: Class I Division 1 & 2,
Groups C, D; Class II Division 1 & 2, Groups E, F, G; Zone 1 & 2, Zone 20, 21
& 22; Suitable for Use in Wet Locations, NEMA Type 6P when fully
assembled.
8.3.
The UVC BODYLight utilizes 10 High-Power germicidal UVC LEDs with a
peak emittance at 265-275nm having an average adjusted output power at 4-
inches (10.16cm) of >2.2mW/cm
2
and at 3-inches (7.62cm) of >3.7mW/cm
2
across a projected 60° beam angle.
