Total Disinfection Using UVC Germicidal Light

Updated on November 21, 2017

My 400 Watt UVC Germicidal Light.

My 400 Watt UVC Germicidal Light.

You know all this started with my intention to eradicate mosquitoes in Sierra Leone, well this piece of kit will do that and has been my secret for years, I'm not out to target the flying ones, I'm looking to kill the eggs and lavre, ok you might say uvc light doesn't work in water, ooops think out of the box, I intend building purpose sized alumium boxes to enclose the eggs and blast with the light, job done the UVC Kills eggs instantly and the larva DNA is destroyed killing them.



I like to thank people who assisted in helping me change my choices in life, who placed suggestions in my head leaving me a choice, to listen and ignore or to listen and do. Well Jim, I listened and I did as you kept telling me --- SEMPLE you need to read more books on technology ---. Well Jim I did just that and what a journey, at the time I had no idea in what direction to start reading books on technology, I read fiction if anything. Well I started reading and still do, its lead me to understanding so many principles regarding old and new technology of which im starting to use or will be using in Sierra Leone. Silly things but essential if you have nothing, like

Desalination of sea water and so many ways to achieve it, using the sun or by steam. Turning into Distilled Water which some doctors say is good for the body.

Building toilet sewage systems that are bio-friendly re-routing waste water to plants.

Building RAM-Pumps to move water from streams to our farm land. 24/7 pumping of water no power required.

Building or making Ovens to heat water to use for baths within the village and soak a ways to remove used water.

Building or making Ovens to produce BIO-CHAR to use once activated within toilet waste tanks to contain odours, also to use on our farm to assist in growing crops.

These are a few of the items I would never have looked at if Jim hadn’t been so persistent, so thanks Jim.

It’s the same with this new venture, for years ive read documents about mosquitoes, how they live, there breeding cycle the full monty, sadly there was always a missing link. How do you eradicate them quickly. Then maybe 3 years ago I read a university students document regarding the use of UVC lights and eradicating bed bugs, it had everything in this document, exposure times and results and it was like an alarm had gone off in my head, UVC light can do that to bedbugs then it will do similar to mosquitoes, so that was that. I now searched for documents on this and found very little.

Although reading other associated documents about insects in general told me then, Yes that is what I must use, so for 3 years ive know the answer. Even in 2014 I had enough knowledge about the use of UV lights to know they would kill the ebola virus and that was positively agreed by the company im purchasing the light from, as they tried to be part of the relief aid for sierra leone but sadly had no contacts who could assist them. Again its not who you are, its who can open the door.

I might ramble on about Mosquitoes, well unless you've had malaria ( twice, last time 4 days intensive care ) or seen loved ones die because of these blood sucking vermin you wont understand. Mosquitoes and there elimination forces me forward, they kill so many people world wide.

Just a little history of why I ended up reading and understand the positive uses of UVC or UV Germicidal lights.


This is interesting piece of information for people who buy Fly Zappers / those blue lights you see hanging in shops and gardens. It has been proven that mosquitoes are not attracted to the uv light being omitted from these Zappers, the female mosquito is the blood sucker and prays on smell , not light, the average kill rate from fly zappers installed in garden settings for mosquitoes is around 4 % the rest being flys and moths plus midges ( related to the mosquito ). This saved me £ 300,00 as I was in process of ordering one to take to sierra leone.

Stating that above does not mean UVC light wont kill insects including mosquitoes, it does but over a period of time. Exposure effects the DNA of the insect / mosquito and stops them breeding and eventually death occurs, time depends on exposure rate of light emitted from light fitting and distance insect /mosquito from light fitting.



Ultraviolet germicidal irradiation (UVGI) is a disinfection method that uses short-wavelength ultraviolet (UV-C) light to kill or inactivate microorganisms by destroying nucleic acids and disrupting their DNA, leaving them unable to perform vital cellular functions. UVGI is used in a variety of applications, such as food, air, and water purification.

UV-C light is weak at the Earth's surface as the ozone layer of the atmosphere blocks it. UVGI devices can produce strong enough UV-C light in circulating air or water systems to make them inhospitable environments to microorganisms such as bacteria, viruses, molds and other pathogens. UVGI can be coupled with a filtration system to sanitize air and water.

The application of UVGI to disinfection has been an accepted practice since the mid-20th century. It has been used primarily in medical sanitation and sterile work facilities. Increasingly it has been employed to sterilize drinking and wastewater, as the holding facilities are enclosed and can be circulated to ensure a higher exposure to the UV. In recent years UVGI has found renewed application in air purifiers.

Shortwave UV Energy or Ozone can be generated by specially designed UV lamps. It is primarily used as an effective sterilant in applications requiring cleanliness with no residual contamination. UV-C is the wavelength used in germicidal applications. It is well know that ultraviolet germicidal lamps can destroy any microorganism that comes in contact with its powerful UV-C rays. This method is recommended by the Centers for Disease Control for its germicidal effects.

Ultraviolet Germicidal Energy is produced by low level mercury lamps. The lamps are made of special glass which allows the passage of light rays emanating at 253.7 nanometers. This particular energy has the capability to kill all micro- organisms it comes in contact with.

The destruction of germs and bacteria by germicidal ultraviolet light is accomplished quickly and effectively. The UV-C rays strike the various microorganisms whether they are bacteria, virus, yeast, mold or algae, and they break through the outer membrane. The radiation reaches the heart of the organisms (commonly known as the DNA) where it causes abrupt modifications. The modified DNA transmits incorrect codes or messages, and this impairment actually brings about destruction of the microorganisms.

Does it work?

Yes, thousands of references to this type of process can be found in literature and in actual applications

UVC germicidal light kills the following.

UVC germicidal light kills the following.


People with flu can spread it to others up to about 6 feet away. Most experts think that flu viruses are spread mainly by droplets made when people with flu cough, sneeze or talk. These droplets can land in the mouths or noses of people who are nearby or possibly be inhaled into the lungs. Less often, a person might also get flu by touching a surface or object that has flu virus on it and then touching their own mouth or nose.

The Flu Is Contagious

Most healthy adults may be able to infect other people beginning 1 day before symptoms develop and up to 5 to 7 days after becoming sick. Children may pass the virus for longer than 7 days. Symptoms start 1 to 4 days after the virus enters the body. That means that you may be able to pass on the flu to someone else before you know you are sick, as well as while you are sick. Some people can be infected with the flu virus but have no symptoms. During this time, those persons may still spread the virus to others.

2. Germs

What are germs?

Germs are tiny microorganisms that exist all around us and are invisible to the human eye. There are many different types of germs. Most are not harmful, but some cause infectious diseases. You probably already know about many infectious diseases. There are vaccines to prevent some and medicines to treat others, but we don't have vaccines and medicines for every kind of infectious diseases . It is important to know about germs and infectious diseases , and simple ways to avoid getting and spreading them.

Where do germs live?

Germs have favorite places to live, preferred ways to travel, and if they are harmful, their own unique ways of causing disease. Germs can live in or on dirt, water, countertops, our skin, our intestines, and in many other places around us. Some germs can survive on their own while others prefer living in people or animals. Some germs live only in hot areas of the world while others live only in cold areas. When germs find a place that is good for them, they multiply and set up a home for themselves.

How do germs spread?

Germs spread in different ways. To catch an infectious disease, you first need to be exposed to a harmful germ. Then it needs to get on or into your body and act in its unique ways to cause disease. Our bodies are good at fighting infections; not everybody who is exposed to germs will get sick, but some will. Here are the most common ways to be exposed:

Touching. Some germs live in body fluids like mucus, pus, and stool. Even the invisible drops released when people talk, cough, or sneeze can carry germs. Touching a contaminated surface or object, then touching your eyes, nose, mouth, a cut, or other opening in the body, can lead to an infectious disease.

Eating or drinking. Some germs exist in food and untreated water. Unwashed fruits and vegetables, and foods not properly cooked or kept at the right temperature, may carry harmful germs.

Breathing. Some germs spread through the air. When someone coughs, sneezes, or talks they can release germs. When harmful germs are inhaled, they can cause illness.

Getting bitten. Animals can carry and spread infectious diseases to people. Bites from wild animals, pets, or even a small animal like a bat or insect can cause illness. Even if the animal doesn't look sick, it may carry harmful germs.

3. Bacteria

Bacterial infections are illnesses that occur when harmful forms of bacteria multiply inside the body. They range from mild to severe. Although they include such deadly diseases as plague, tuberculosis, and cholera, these and many other bacterial infections can be prevented by good sanitation or cured by antibiotics.

Bacteria are everywhere: in soil, in water, in air, and in the bodies of every person and animal. These microorganisms * are among the most numerous forms of life on Earth.

Most bacteria are either harmless, or helpful, or even essential to life. Bacteria break down (decompose) dead plants and animals. This allows chemical elements like carbon to return to the earth to be used again. In addition, some bacteria help plants get nitrogen. Without them, plants could not grow. In the human body, bacteria help keep the digestive tract working properly.

Like viruses, however, bacteria can cause hundreds of illnesses. Some bacterial infections are common in childhood, such as strep throat and ear infections. Others cause major diseases, such as tuberculosis, plague, syphilis, and cholera. The infection may be localized (limited to a small area), as when a surgical wound gets infected with a bacterium called Staphy loco ccus (staf-i-lo-KOK-us).

* microorganisms are living organisms that can only be seen using a microscope. Examples of microorganisms are bacteria, fungi, and viruses.

Some bacteria, such as pneumococcus (noo-mo-KOK-us), which is also called Streptococcus pneumoniae, almost always cause illness if they get into the body. Others, such as Escherichia coli, usually called by the short form E. coli, often are present without doing harm. If the immune system is weakened, however, these bacteria can grow out of control and start doing damage. Such illnesses are called "opportunistic infections." They have become more common in recent years, in part because AIDS, organ transplants, and other medical treatments have left more people living with weakened immune systems.

How do bacterial infections spread?

Different bacteria spread in different ways. Examples include:

  • through contaminated water (cholera and typhoid fever)
  • through contaminated food (botulism, E coli food poisoning, salmonella food poisoning)
  • through sexual contact (syphilis, gonorrhea, chlamydia)
  • through the air, when infected people sneeze or cough (tuberculosis)
  • through contact with animals (anthrax, cat scratch disease)
  • through touching infected people (strep throat)
  • from one part of the body, where they are harmless, to another part, where they cause illness (as when E coli spread from the intestines to the urinary tract).

4. Fungi and Yeast

Fungi, the word for more than one fungus, can be found on different parts of the body. Here are some common types of fungal infections:

  • Tinea (say: TIH-nee-uh) is a type of fungal infection of the hair, skin, or nails. When it's on the skin, tinea usually begins as a small red area the size of a pea. As it grows, it spreads out in a circle or ring. Tinea is often called ringworm because it may look like tiny worms are under the skin (but of course, they're not!).
  • Because the fungi that cause tinea (ringworm) live on different parts of the body, they are named for the part of the body they infect. Scalp ringworm is found on the head, and body ringworm affects any other skin areas.
  • Athlete's foot is another type of fungal infection that usually appears between the toes but can also affect toenails and the bottom or sides of the feet.
  • Jock itch is a fungal infection of the groin and upper thighs. You might think only men and boys get it, but girls and women can get it, too.
  • Candida (say: KAN-dih-duh) is a yeast, similar to a fungus. It most often affects the skin around the nails or the soft, moist areas around body openings. Diaper rash in babies can be from one type of candidal infection, as can thrush (white patches often found in the mouths of babies). Older girls and women may develop another form of candidal infection in and around the vagina. This is called a yeast infection.
  • Pityriasis versicolor (say: pih-tuh-RYE-uh-sis VUR-suh-kul-ur) is a mouthful to say. It's a rash caused by a fungus that normally lives on human skin. It can appear over the chest, shoulders, and back, and is common in teenagers.

Kids Get Fungal Infections?

Lots of kids get fungal infections. Kids love to share and hang out together. Some of these infections are contagious (say: kon-TAY-jus), which means they easily spread from person to person. Close contact or sharing a comb or hairbrush with someone who has tinea can spread the fungus from one person to another. Because fungi need a warm, dark, and humid place to grow, public showers, pools, locker rooms, and even the warmth of shoes and socks can give fungi the perfect opportunity to strike.

  • Taking antibiotics can cause some kids to get a yeast infection. Antibiotics get rid of germs that make us sick, but they can also kill many of the harmless bacteria in our body. These harmless bacteria normally fight with the yeast for a place to live, but when antibiotics kill them, the yeast is free to grow.

5. Dust Mites

Dust mites tend to infest most households. They feed on dead skin cells, and since cleanliness doesn't stop humans from constantly shedding skin cells, dust mites will eventually show up. Where there's one dust mite, there are many more. For those with allergies to dust and dust mites, this can become a serious problem. If you have dust mite allergies, the most important thing that you can do is control the level of the allergen in your environment. How do you do this? You take aim at your bed!

The place where you're most exposed to dust mites is the place where you spend the most time in little or no movement - for most people, that's the bed. Why? Dust mites like to live on the skin cells that you shed. Every day, dead skin cells on the surface of your skin fall off to reveal newer living ones. Each time you roll over in bed, or when you switch positions on your pillow, the dead skin cells are left behind on your bedding and in your mattress. Those cells are the dust mite's favourite food. So every night, for 6 to 8 hours a day, you end up feeding one of the main sources of allergens!

Dust mites are too small to be seen, but are the most common cause of year-round allergy and asthma. Dust mites live in mattresses, pillows, curtains, carpets, sofas, loveseats, chairs, other furniture, bedcovers, clothes - and anywhere else they get to eat dead microscopic flakes of human skin. The problem for us is what the dust mites leave behind. It is their droppings, the waste products, that are highly allergenic. People with dust allergies and/or mold allergies very frequently have a dust mite allergy to dust mite droppings.

What are the allergy symptoms for allergies to dust, dust mites and/or dust mite droppings?

Asthma, Bronchitis, Inflammation of the Mucous Membranes, Eczema, and Itchy Red Eyes, are some of the most well known symptoms. There is a whole host of other Allergy related conditions, including chronic fatigue, irritability, mood swings, and even depression, which have been proven to be caused by allergies.



To assist you in the disinfection of your work place / home. As you can see from reading the above text, most issues are caused by other people / animals we come into contact with or who have left germs behind them by coughing or spitting on surfaces.

Typical areas we are looking to target are the following

Private Dwellings




Public Transport- tubes-buses-trains and taxis

Public Buildings

Doctors waiting rooms

Dental waiting rooms

Children,s creshe

Police Cells

Court Cells

Office Work Stations

Full office cleanse

Shipping Containers, internal and external



Toilet Blocks

Construction Site Set Ups


Housing Associations

Retirement Homes


Farm Buildings

There are other areas.

Using this system to Disinfect areas / surface does not do away with good house keeping, this takes it to another level of cleanliness, so if I turn up and the place / area looks like a rubbish tip , it will still look like a rubbish tip when I leave , just a disinfected rubbish tip.

The major issue with a business like this is , there is no evidence that the area has been disinfected but guaranteed if I shine this 400 watt germicidal lamp across a surface / bed / carpet / work station on any other area, it will kill all in its path.

Safety is paramount whilst using this equipment, risk assessment has to be done for each area to ensure my safety , your safety and any animals safety be they pets or wildlife. ( with exception to bugs and insects )

I will be using the business in London area at this present moment, but have had a few interesting emails from people in Africa and India were they have issues, so the world is a small place.
