Lumalier FAQs
UV disinfection technology is quite amazing and often misunderstood. It's helpful to understand the proven science of UV, as well as the benefits, appropriate applications, and importance of quality products and installation as you explore systems for air and surface disinfection for your application.
FAQs
Below are some questions we are often asked, but we have an extensive library of information and experts available for further discussion should you have additional questions. You can also learn more by visiting our Industries page, where we have details on a broad range of facility types and UVC applications. Please let us know how we can help.
UV Light
How can light destroy germs and biological contamination?
Ultraviolet light has three principal wavelengths: UV-A, UV-B, and UV-C. Ultraviolet light generated in the UV-C spectrum (254nm) is classified as 'Germicidal' because it will alter an organism’s DNA so that it can no longer reproduce - making it effectively harmless. Without the ability to reproduce, the microorganism population is rapidly eliminated.
Is ultraviolet light harmful?
UV-A is also known as "blacklight" and is generally harmless. It results in skin tanning and is used in medicine to treat certain skin disorders.
UV-B has a very high penetrating ability and prolonged exposure is responsible for some types of skin cancer, skin aging, and cataracts.
UV-C, also known as Germicidal UV has been used safely and effectively in hospitals, clinics, laboratories, and industry for more than 50 years. UV-C has extremely low penetrating ability and is nearly completely absorbed by the outer, dead layer of skin where it does little harm. Over exposure, can cause reddening and temporary, but painful irritation to the most superficial layer of the eye, but it cannot penetrate to the lens of the eye and cannot cause cataracts.
Is it true that some UV-C will produce ozone?
No. The UV-C devices that Lumalier installs will produce no ozone. UV-V produces ozone, and Lumalier does not use UV-V lamps.
What Is UVGI?
Germicidal UV has a specific wavelength of 253.7 nanometers (253.7 billionths of a meter) and is known to deactivate (break the DNA of) germs contained in tiny airborne droplets (droplet nuclei) that transmit diseases such as measles, tuberculosis, and influenza from person to person.
Once the DNA of a microbe is broken, it loses its ability to reproduce. Bacteria and viruses that cannot reproduce are rendered harmless.
