Germicidal UVC lights generate ultraviolet waves that kills viruses, bacteria and mold. The light, sometimes referred to as a nano UV disinfection light, stops the germs in their tracks, damaging their DNA so that they can no longer replicate. UVC light attacks viruses, bacteria and pathogens on the surfaces in the environments we are exposed to.
England's Deputy Chief Medical Officer, Dr Jenny Harries, told the BBC in March that the coronavirus can live on soft surfaces for 24 hours, and hard ones for 48 hours.
More recently, The Guardian reported on a new study by The New England Journal of Medicine from March 17. It found the coronavirus lasted on plastic and steel for up to 72 hours, cardboard for up to 24 hours, and copper for up to four hours.

Note: LED UVC Lights are not to be used as a means of sterilization on people, pets or plants.
Our High Power LED UV Germicidal Lights are:
80% UVC at 275 nm (invisible spectrum - optimal range is 270-280 nm)
20% UVA at 400 nm (provides purple glow to indicate light is working)
Does not produce Ozone
UV refers to ultraviolet light produced by the Sun.
UVC refers to UV light with the wavelength between 200-290 nanometers (nm). It is almost entirely filtered out by the atmosphere before reaching the Earth’s surface.
UVC LED reproduces the UVC light by taking a special wavelength between 260–280 nm.
UVC eliminates up to 99.99% of germs and bacteria by destroying their DNA & RNA, reduces unpleasant smells by decomposing molecular structure of odor. It is a non-chemical disinfection method being used by hospitals and aerospace applications for decades.
UVC Light - Its effectiveness varies by spectrum
UVC light follows a visible spectrum range of 180 nm to 280 nm. When we talk about UVC light, its important to understand how effective the UVC product is. According to Global Lighting Association, spectrums closer to 280 nm are far more effective than spectrums closer to 180 nm.
How to interpret the above UVC effectiveness chart
Column 2 lists spectrum range, column 3 list effectiveness. You will notice 180 nm is 0.012 effective (out of a score between 0 and 1) and 270 nm is 1.0 effective (very effective)
You may have heard of FAR-UVC. FAR UVC in the above chart is indicated at 222 nm. It is 0.13 effective
What about UVC fluorescent tubes? Its listed on the chart at 254 nm. It is only .50 effective.
Our LED UVC products are in the 270-275 nm range. It is 100 efficient at killing viruses and pathogens
So when comparing our LED UVC against the competitors fluorescent UVC products, keep in mind you would need 'more' fluorescent products to achieve the same results as LED UVC

LED UVC Germicidal Lights
UV light occurs naturally in nature. Its created by the sun. In particular, there are three spectrums of UV light that matter: UVA, UVB and UVC. And make no mistake about it, these spectrums are considered to be "light", although some are not visible to humans. Our eye sight cannot detect these invisible spectrums but they do exist.

What is UVA Light?
UVA makes up the largest source of ultraviolet light that reaches the planets surface. To humans, it is capable of penetrating deep into skin tissue. It is thought to be 80% responsible for aging of the skin issues - like age spots and wrinkles. Most recently, its been recognized as a source that contributes to skin cancer.
What is UVB Light?
UVB can also be harmful to humans. It is less common than UVA, however, it can damage our skin DNA. It is the UV source that contributes to sunburn. This is the spectrum that's mostly linked to skin cancer.
What is UVC Light?
This spectrum is very good at destroying genetic material. Unfortunately, it doesn't differentiate between good genetic material and bad. It will cause harm to humans (good) and viruses (bad).
So why isn't UVC light more of a problem now? That's because the earth's ozone layer filters most of the UVC spectrum out. So the good in this is it keeps people safe. The bad part is we lose its ability to kill viruses, bacteria and other harmful pathogens.
UVC light is also particularly damaging to eye sight. The reason is that the light source is invisible to us. When people are exposed to a bright light source, they have mechanisms to deal with this. They turn away, they blink, the close their eye lids, or block the light with their hands. UVC light is not detectable to us. So we don't naturally try to avoid or protect ourselves from this light source. So it can cause serious and permanent damage to our eye sight if we are exposed to it.
Scientists discovered in 1878 that UVC light could be used as a method of sterilization. And this method is a common place in hospitals, dentists offices and even nail salons to disinfect tools after use. UVC light is used in water treatment plants, HVAC units and hot tubs as a means of sterilizing bacteria and viruses.
Other methods of sterilization has become ineffective to some forms of pathogens, bacteria's and viruses. Heat is sometime used, but some pathogens have built resistance to heat. And using dangerous chemicals like bleach is not always a good option (or even an option). UVC has been found to be very effective in destroying these pathogens. But as mentioned, it has its own risks and so proper use of this technology is important.
The sweet spot for UVC is between 270 and 280 nm. Our lights are 80% UVC at 275 nm and 20% UVA to provide a visible purple glow to indicate the light is operational.
How long to do you need to run our lights? It's the run time to achieve 90% effective destruction rate. Our UVC products are all the same size and cover the same area. The difference between the lower wattage and the higher wattage units is the higher wattage units can achieve the 90% destruction rate quicker.
Our 200 Watt UVC High Bay will be 2X faster than the 100 Watt unit and 4X faster than the 50 Watt unit in achieving the 90% rate. If you are looking for a higher effective destruction rate (90-99%), you have to increase the run time or increase the wattage used.
What is good use of UVC Light?
Containment of UVC light is important. That's why many good products you see are sealed boxes or machines where you place materials inside, close the lid, and turn on the device to perform sterilization. It's in contained environments, with the absence of people, that UVC light is effective and safe. Creating safe sanitizing areas, either by design or the containment area, or the design of the product, is essential for keeping people safe while getting the benefit of UVC sterilization.
What is a bad use of UVC Light?
UVC light should never be thought of as an acceptable method of sterilizing people or pets. You should not, for example, use UVC light as a hand sanitizer in place of soap and water or alcohol based products. It should never be used to sanitize employees in the entrance areas of commercial buildings
How to Practice Safe UVC Sterilization?
Create a safe sterilization room
A sterilization room is one that controls what is placed in it, and more importantly, locking access to it when the sterilization process is in use. Smaller versions of these, known as UVC boxes, are found to sterilize small items like cell phones. Larger versions can be created in hospitals, schools and commercial buildings where items are rolled in, doors are locked, and the UVC lights are turned on. Safe protocols and practices must be employed, along with fail safes (motion detection turns off the lights) to keep the area safe.
Create a safe practice
It is not always possible to use UVC lights exclusively in a safe room. For example, as a commercial business, you may have a room, such as a lunch room, that you need to sterilize every day. It is not practical to move all the tables and chairs into your sterilization room on a daily basis.
However, it is reasonable to run the sterilization process at 2:00 am, when no one is around. A safe practice would include being able to lock the light switch to this product so it could not be turned on accidentally. Locking the room at night and unlocking it in the morning would further safe guard the room from being entered when sterilization is being performed.
Use a LED UV Light with built in safe guards
LED Lighting Supply's High Power UVC lights have safety features built in to make sure they operate in a safe fashion. Timers can be set so they only operate at times when people are known not to be around. Alarms are triggered before the lights turn on to warn people to leave the area. And most importantly, motion detectors turn off the lights when motion is detected and turn back on when motion is not detected.
Because UVC is not visible, our lights also have UVA spectrums, which glows a light purple when the light is on. So visibly, you can detect when the light is on.
But even with these safe guards, safe operating practices needs to be employed to further safe guard the use of these products. These products can provide a great option to sterilize objects and environments, but they must be safe and used in a safe manner.
Avoid using UVC lights on people and animals
UVC light is not a people or pet disinfecting tool. Never use UVC light when people or pets are under its beam. UVC cannot differentiate between good and bad life forms. It does not discriminate between people and pathogens such as bacteria and viruses. While it does a great job on pathogens, it is also harmful to people and should never be used in rooms or areas when people are present.
Comparing UV Fluorescent Tubes to LED UVC
There are some who are making claims the LEDs are not effective in being a disinfecting light source because the LED spectrum is at 400nm, essentially, UVA. They are both right and wrong in making this statement. 400nm is not an effective wavelength to destroy the DNA of bacteria, germs, viruses and mold. You need to be between 270 and 280. The problem is they are unaware that our LED UVC lights produce 275nm UVC light. Their error is only in the fact they are not aware our product exists.
But what about tubes? Most UVC fluorescent tubes are dialed in at 253.7nm. While they are theoretically within the UVC spectrum, they are not at the most effective range. Keep in mind, these mercury based products need to be recycled when end of life happens, which is typically after 1 year.
The EPA does not confirm whether UV devices might be effective against viruses and bacteria, and rather advises that that the effectiveness of any UV device “will depend on a variety of factors including, but not limited to, the device’s duration of use, distance of the light from the surface intended to be treated, the UV wavelength, the specific pest being targeted, the strength or wattage of the UV light bulb, the age of the UV light bulb, shadow areas or other factors.”
LED Lighting Supply uses a custom UVC calculator. It takes input that includes the length, width and height of the room, the UVC model chosen, and time. From that, we can calculate sterilization rates for any specific location within that room. We can alter time and UVC watts to give you an effective sterilization recipe. Our units have been SGS certified - a test to confirm that our lights are effective against viruses and bacteria and pathogens. LED Lighting Supply calculates the amount of time and power required to deliver pathogen sterilization for a specific area.
Can UV LED lights kill bacteria?
The wavelength of 264 nm is very effective at killing germs, viruses and bacteria. UVC radiation can pass through air without creating ozone. UVC lamps can be used in air to disinfect surfaces. UVC LEDs can play a useful role in preventing infectious disease.
Is UVC light harmful?
Some forms of UV light can penetrate the skin and cause issues like cancer. UVA and UVB occur naturally in nature and is produced by the sun, Its was causes sunburn when we are over-exposed to it. It can lead to skin cancer. Studies show that UVC light is blocked by dead skin cells from penetrating the skin. However, prolonged and intense exposure to UVC lights, such as using them in tanning beds, should be avoided.
Do LED UV lights work?
Hospitals and laboratories use ultraviolet (UV) light to kill microbes, and bacteria. It is also found in what purification systems, like hot tubs and water treatment plants, to kill bacteria in the water. Researchers found that far UVC eliminated bacteria on surfaces but was not harmful to humans when exposed to the lab animals.
