UV light is not visible to the human eye and works in different wavelengths. UV light has a little wavelength than the light we can view. UV light is also more power rich, for example, trigger a chemical reaction. This is one of the reasons that the radiation of UV is bad if you come into contact with it for too long.

How UV light kill bacteria and viruses
Using UV light disinfection, the cell walls of virus, bacteria and protozoa are penetrated; permanently change the DNA of the microorganisms. This successfully inactivates the microorganisms, making them not capable to infect and reproduce. As the cells are not capable to reproduce, they will not be capable to cause any infection, thus killing the viruses and bacteria. This causes the pathogens to become non-infections by destroying its DNA.

UV disinfection has become the best water disinfection solution to kill and inactive microorganisms, viruses and bacteria, due to its many benefits. A bigger disinfection is chlorine, which has proven to lead to many health issues such as respiratory diseases.
The many benefits of UV include:

• Low maintenance, operating costs, and administration
• A lower carbon footprint matched to the substitute disinfection techniques
• No risky chemicals involved
• No change in the water features such as temperature and pH
• No by-products being included in the process
• Quick treatment, meaning there is no processing time
• Simple and safe implementation

How long does it take to kill bacteria?
The amount of time it takes for UV light to kill germs and bacteria depends on number of factors.

One of them most vital factors to consider is the bacteria type to be targeted. This is due to some bacteria being more resistant to UV light than others, which means that they need a longer exposure or top UV dose to be inactivated. Assessing which virus or bacteria to inactive is the primary step to consider before advancing with the individual water treatment case.

Another vital factor is the UV lamp intensity, which issues the amount of UV radiation that is needed to inactive the targeted viruses or bacteria. This naturally means that lamps with higher intensity will be capable to inactive the bacteria more immediately than low-intensity UV lamps.

UVT% would need UV lamps with lower intensity, as the UV light is better capable to “reach” the microorganisms.

All these factors must be taken into account when assessing the best UV system for the specific water treatment situations to be achieved – including bacteria inactivation.

Let’s be clear
UV lamps or flashlights do not contribute to the quick elimination of viruses, such as coronavirus. We know that UV flashlight like Arkfeld Pro Flat ED flashlight can help you to notice stains and dirt particles.

Viruses don’t like Vitamin D or sunlight so while they may give some level of protection remember that too much exposure to sunlight can also be harmful to your health. UV light is perfect for disinfecting air, water, and objects.

What are the other purposes of UV flashlight?

Insect spotting
UV light is generally used in insect entomology and spotting for many objectives, including identifying species, insect behavior, and controlling insect populations. Insects particularly certain species like bees, scorpions, and some types of beetles, have compounds in their bodies that fluorescent under UV light. This fluorescence can range from blue to green to white, dep3ending on the species and the compounds present.

By using UV light sources, such as black lights or handheld UV flashlights, insect and entomologist lovers can successfully spot and identify insects, mainly in dark and low-light atmosphere. This technique is particularly help in nocturnal insects that are active during the night.

In addition to identifying insects, UV light can also be used in pest control techniques. For example, some insect traps and pest control devices like use UV light to attract and capture flying insects like flies, mosquitoes and moths. The UV light attracts these insects, causing them to fly toward the light source and get trapped.

Crime scene investigation
Law enforcement provides often use UV flashlights to detect proof that is not visible under general lighting conditions. This may contain fingerprints, blood stains, and other proof that can be exposed to ultraviolent radiation.

Leak detection
UV flashlights can be used to notice leaks in pipes and other structures by following the attendance of fluorescent dyes added to the system fluid. This makes it easy to find the source of the leak and repair it.

Difference between UV light and black light
Both types of light are just pretty beyond that spectrum, and the last color we are capable to distinguish here is violet due to the red receptors in our eyes. So, what is the difference between these two?

Black light
To put it simply, black light is an ultraviolet light type – mainly UVA light, where it emits UV radiation in the UVA band. These rays are low-power and long-wavelength and are least bad as far as ultraviolent radiation is concerned. You would not want to stare at a black light for very long time, but it is UVC and UVB light that represent the worst types known to cause sunburns and even skin cancer.

Ultraviolent light
On the other hand, UV light is made up of both UVB and UVA light, but not UVC light. UVC light would technically be the most bad and risky of all, but it does not reach the earth area and is instead absorbed by the ozone layer. UVB and UVA light seem to be the cause of the black light vs. UV light confusion, but the disinfection is pretty simple. The power of both in conjunction provides the capability to sterilize water, surfaces and even air. This is due to the mixture of the two, but mainly UVB rays which have a medium wavelength and are capable to cause more problems to the DNA contained in our skin.
