Ligting FAQs
What are UV lights, Ultraviolet lights and Ultraviolet radiations?
Sun is a main source of energy to earth. Sun transmits the energy and light in the form of radiations. From these radiations, UVs has more energy than radio waves or visible-light but less energy than X-rays or gamma rays.
What are UVA, UVB and UVC?
UVs or ultraviolet lights normally fall in different EM (Electromagnetic) Spectrum between visible and X-rays with different frequency ranges. UVs have generally three sub domains depending upon their frequency range.
- UVA, or near UV (315–400 nm)
- Contains low energy
- Linked to skin aging and damage
- Human are directly exposed from the Sun
- Large source from Sun
- UVB, or middle UV (280–315 nm)
- A small amount of Sun contains this radiation
- Main radiations that causes sunburns & skin cancers
- UVC, or far UV (180–280 nm)
- High energy UVs
- Mostly absorbed by Ozone layer
- UVC lights are mainly human made
- UVA, or near UV (315–400 nm)
How does UV light kill bacteria?
Ultraviolet lights (UV lights) initiate a reaction that can cause DNA damage in cells. UVC lamps are normally used for decades for killing bacteria from water and different surfaces. Therefore, UVC lamps are also known as germicidal lamps.
Are germicidal lamps a proper solution for COVID-19?
According to different studies, different germicidal lights or UVC Lights damages the outer protein structure for different SARS-Coronavirus. The structure of current Covid-19 does not confirm UV lights are also as much effective as SARS-Coronavirus. However, it may be inactive the current SARS-CoV-2 which is the main cause of Covid-19.
