UV-C basic information
What is UV-C?
Ultraviolet (UV) light is invisible to human eyes. It can be subdivided into three categories:
-
UV-C from 200 to 280 nm - For disinfection purposes and germicidal application.
-
UV-B from 280 to 315 nm - For medical use (i.e. phototherapy to treat skin conditions, including psoriasis).
-
UV-A from 315 to 400 nm - For use with curing, suntanning and insect traps.
How does UV-C work?
-
UV-C radiation can break the DNA and RNA of bacteria, viruses and spores, meaning that they leave them harmless. There
are no known micro-organisms resistant to UV-C
-
UV-C technology has been used safely and effectively in hospitals and governmental buildings for more than 40 years
-
Most UV-C solutions utilize conventional lighting, with LED now improving in efficiency.
-
The peak output of our germicidal lamps (253.7 nm) is close (80%-85%) to the maximum effectiveness of UV-C (265 nm).
-
Smaller UV-C wavelengths (222 nm) are being explored as less harmful alternatives.

Installation requirements and safeguards for this product
The device described in this guide is designed to operate and provide UV-C irradiation in the open air of indoor rooms for
disinfection. The disinfection happens in a germicidal zone over the height where people are occupying the room. Staying in the
room where these luminaires are installed and turned on is allowed if the below instructions are followed while being present in
the subject indoor room. To achieve this safe condition, the following precautions must be taken and followed and kept during
use:
2.1
Installation, electrical connection, and verification of installed products,
2.1.1 Installation of the products referenced herein should only happen after a design of the UV-C irradiation in the application
itself, which defines exact positions for installation. (referenced commonly as lighting design).
2.1.2 The product installation must follow the pictorial instructions provided in this document, with the below precautions to
be followed:
a. Check the product after unpacking for damage. Do not install physically damaged product.
b. Only install into ceilings that meets the following criteria:
i.
Suitable to hold luminaire weight
ii.
The ceiling is horizontal and suitable for the size of the fixture
iii.
The product must be installed in a safe height as described in the pictorial instructions
iv.
Attach safety anchorage strap to the luminaire to both top connection points (behind the ceiling after
installation), as additional safety measure (safety strap not included)
2.1.3 The product must be installed on a power circuit which meets the following criteria:
A.
Can be turned on/off separately from any general lighting used in the building
B.
It meets the national electric code of the actual country of use and installation
C.
It is separated from any lighting system by its own circuit breaker
D.
The input power switch must be lockable for safe shutdown during maintenance
