Pure-Light makes no claims concerning being used as a treatment or cure of any kind for any disease.
Pure-Light is currently in PRE-LAUNCH.
Our full-spectrum LED light bulbs are coated with titanium dioxide which is a photo-catalyst that removes bacteria, viruses, mold, fungus, odors and toxic chemicals from the air in your home, office, RV, or any other location.
48-inch LED TUBE LIGHTS:
The photocatalytic process breaks down toxic indoor air pollutants like formaldehyde, carbon monoxide, methane, benzene and other VOCs into harmless components. (The main components of deadly "smog")
ANTI-ALLERGEN The process also neutralizes pollen and other allergens. You can literally help make your home hypo-allergenic.
DESTROYS ODORS without masking them with fragrances.
Eliminates the need for harmful chemical sanitizers.
Eliminates aerosols that deplete the ozone layer.
DAYLIGHT BRIGHT FULL SPECTRUM also known as the "HAPPY LIGHT" that helps fight winter blues. (Same type of light used to overcome S.A.D. at 1/2 the cost).
COOL TO THE TOUCH SAFE + Eco-friendly, odorless, non-toxic.
New patent pending technology allows it to work indoors for up to 10 years.
Helps comply with indoor air quality regulations.
Uses 70%-90% less energy compared to incandescent bulbs.
Uses 50% less energy compared to fluorescent lights with no mercury.
Lasts 10-20 times longer than incandescent and fluorescent bulbs.
INSTANT ON, high quality, flicker free lighting.
Produces less heat and reduces fire hazards.
Silent operation with no filters or maintenance.
Fits into any standard light bulb socket.
Great for plants and animals (in actual lab tests, Pure-Light bulbs increased plant growth over regular greenhouse lighting, and plants were healthier overall).
According to the EPA, the air inside your home may be up to 100 times more polluted than the air outside.
Most Americans spend up to 90% of their time indoors. Recent studies have shown that no home is immune to indoor air quality problems. New homes tend to have higher concentrations of chemicals. Older homes are breeding grounds for mold and mildew. And all homes, no matter how clean they appear, are contaminated with airborne bacteria, viruses, fungi and mold.
For children, seniors and those who suffer from allergies or asthma, the effects may be long lasting and devastating. Pollutants in the air in your home can cause aggravated allergies, asthma and other health problems. Spray disinfectants that often just mask an odor, can be harmful to humans and household pets, too.

Laboratory tests comparing the growth of barley grass under LEDs with and without TiO2 showed that the TiO2 coated lights created an environment that doubled the growth rate of the barley grass but reduced the growth of mold by 80%.
Using a new patent pending process, PURE-LIGHT TECHNOLOGIES™ coats light bulbs with an ultra-thin, transparent coating of an enhanced Titanium Dioxide formula (TiO2) that reacts with light to produce free radicals that are attracted to viruses, bacteria, mold volatile organic compounds (VOCs) in the surrounding air.
In the oxidative reaction, the positive holes react with the moisture present on the surface and produce a hydroxyl radical and the excited electrons react with atmospheric oxygen to form superoxide radicals. As air comes near the PURE-LIGHT coated light bulbs the free radicals generated by the light bulb help to cleanse the air of bacteria, viruses, mold, and pollutants. The air also gets deodorized as well since almost all odors are volatile organic compounds.
The hydroxyl radical is often referred to as the "detergent" of the atmosphere because it reacts with many pollutants called Volatile Organic Compounds (VOCs), often acting as the first step to their removal. There is also a secondary PURE-LIGHT effect on the surfaces of items near the light bulb, such as kitchen/bathroom counters, dishes, stoves, cutting boards, door knobs, etc.
THE LIGHT MUST BE ON. It takes about 45min once the light is on for the photocatalytic action to start (for the negative ions to start to be generated).
BULBS MUST BE OPEN TO THE AIR. Putting bulbs in a sealed cover doesn't do any good. They must be open to the air.
A FAN IS NOT NEEDED TO CIRCULATE AIR. The bulbs will work so long as air can naturally circulate near and around the bulb.
THE BULBS CAN BE USED WITH LAMP SHADES. The air needs to be able to circulate around the bulb.
THE MORE BULBS IN A ROOM - THE BETTER. 2-3 Pure-Light bulbs in an average room (15 ft x 15 ft) seem to work the best.
FULL SPECTRUM BRIGHT DAYTIME WHITE LIGHT. Pure-Light LEDs are full spectrum and provide light with a color spectrum that is very similar to natural daylight. They provide all colors of light with an emphasis on red, yellow, and green light (wavelengths between 480-680 nanometers).
10 WARRANTY (on the A19 bulbs) No receipt is needed. Though the bulbs are nearly unbreakable, they can be broken. If the outside of the bulb is damaged, then the warranty is voided. Otherwise, if the bulb fails to perform in any way, simple return it for a replacement bulb.
ULTRAVIOLET LIGHT SANITIZATION Pure-Light does NOT use ultraviolet light. Ultraviolet light is deadly to all life forms for a variety of reasons. Including animal life and plant life. Because of this it is used as a method of sterilization. Ultra-violet light IS an effective method of sanitation. Ultraviolet lamps are used in sewage treatment plants, hospital clean rooms and many other areas where killing bacteria, viruses and spores is crucial. Ultraviolet light kills cells by damaging their DNA.
UVC light can initiate a reaction between two molecules of thymine (one of the compounds found in DNA). UVC light can cause adjacent thymine molecules in DNA to stick together or "dimerize". If enough of these defects accumulate on a microorganism's DNA then its ability to replicate is inhibited. The longer the exposure to UVC light, the more thymine dimers are formed in the DNA. If cellular processes are disrupted because of DNA damage, the cell cannot carry out its normal functions. If the damage is extensive and widespread, the cell will die.
The harmful effects from exposure to ultraviolet (UV) radiation can be classified as acute or chronic. The acute effects of UV-A and UV-B exposure are both short-lived and reversible. These effects include mainly sunburn (or erythema) and tanning (or pigment darkening). The chronic effects of UV exposure can be much more serious, even life threatening, and include premature aging of the skin, suppression of the immune system, damage to the eyes, and skin cancer.
The long term negative effect of ultraviolet light is well documented. The problem is that it damages/kills good cells as well as bad cells. Please note also that it is only partially effective in sanitizing because it only destroys the cells that the ultraviolet light actually shines on directly. Bacteria in the shadows are not affected by ultraviolet light.
However, ultraviolet light is only able to harm cells that it contacts. Even a small crack can hide spores in its shadow, keeping them safe from the UV. Ultraviolet light is also harmful to people (it damages our DNA too!) Ultralight sanitization is possibly a better alternative to some of those other nasty chemicals out there - as long as we avoid direct exposure.
PHOTOCATALYSIS USING NATURAL LIGHT Pure-Light does not produce, use, or need to use harmful UltraViolet (UV) light. Pure-Light uses Super-Oxygen technology. Superoxide molecules are produced by photocatalytic action that occurs on the titanium dioxide coating that is applied to the surface of the bulb. It is the superoxide molecules that provide the sanitizing action, not the light itself. Plants exposed to Pure-Light grow faster and are healthier, and the Pure-Light action can even sanitize deadly bacteria that may be hiding in the shadows.
I got my first bulbs today. Wow do these bulbs light up your space! I also did the heat test: I put two bulbs in a dual socket. One standard 75 watt common bulb and one 9 watt Pure-Light bulb. I turned on both lights for 5 minutes and then I tested the heat. The 75 watt was so hot that if I had held on to it I would had burned my fingers good. The Pure light bulb was warm but I could hold it without burning my fingers. The pure light was so bright. It was brillant and very intense light. Like sun power - Oh my Lord - was it bright! It filled the room with this amazing light that I have not experienced before. I am amazed. Now I really know I have a better lighting in the house. I now am looking over time for other things as air cleaning also some mold I had from the hurricane in October 2017. I am watching and seeing the results. Just 9 watts of power and more brightness. I am very impressed indeed. --Demetrios P, Florida
"My office is next to my boss's office and he is a chain smoker. Even though I have air purifiers in my office it still smells like cigarette smoke all of the time. In desperation I replaced the bulbs in my office with the Pure-Light bulbs. Now, when I come into my office in the morning it smells like stale cigarette smoke. After turning them on about an hour or so, the smell is gone. God bless you. I am trying to get permission to start leaving the lights on in my office all night so that even in the morning it smells clean." --R. Laird, Tennessee
"I am so thrilled! I got the 'Pure Light' light-bulbs in this afternoon, finally! About an hour ago I put 6 bulbs in. 1 in the bedroom, 1 in the bathroom, 2 in the hallway and 2 in my laundry room. Coincidentally, I have been doing laundry all afternoon and what a difference, wow!! So glad I got them. I was a bit skeptical, not knowing what to expect, but they are worth every penny! Thanks Diane, for telling me about them!!! It is like the middle of a lovely summer day in here. Fumes leave very quickly. We got skunk scent here for the first time I have been here, and now that smell is gone (it still smells outside though). People's cooking smell in the hallway, which finds its way in here too, that is gone. Well I am impressed!!! And all the other invisible benefits we read about....that is very good! My kitties are looking around happier and my plants, I am sure will love it! These light bulbs are cool to touch, so it will be great in the summer time, since my regular bulbs give out lot of heat and the unhealthy fluorescent or the energy saver / spiral ones are really bad for us, so I do not used those, never did." --Alena, Canada
"Hello - I would like to provide this testimonial as to the effectiveness of the PURE-LIGHT (PLT) light bulbs. I will preface this by saying the bulbs were first installed while my wife was out of town for a few weeks. The PLT bulbs replaced “normal” LED 9 watt light bulbs and located in a bathroom (where litter boxes are located) and family room (where the dog spends 18 hours per day). We have multiple cats (& one dog) and the resulting background odors associated with pets. The PLT were initially left on overnight for a couple nights and then for 2-3 hours per day. I noticed an immediate reduction of odors overnight and pretty much elimination of odors within one day. My wife returned from her trip and was amazed by the reduction of odors. I had a friend who wanted to try out the PLT bulbs, so I removed my bulbs & installed the normal LED bulbs. My wife walked into the house that night (following a 12 hour shift at the hospital) and immediately asked where “her” PLT bulbs were and “asked” me to re-install immediately. That was proof enough for me as to the effectiveness of the PLT technology." --Troy, Ohio
"I am so thrilled with these light bulbs. I ordered 12 last night through a friend of mine who has seen great results with hers. She allowed me to take 2 home from her order. Upon arriving home I found out my plumbing had backed up and there was a sewer smell throughout my home, primarily in the kitchen. I put a bulb in one of the kitchen sockets and left it on all night. When I awoke this morning and went into the kitchen, there was no more stench! I was so impressed I called and increased my order to 18 bulbs so, I can gift some and put them throughout my home. I am so grateful for this new technology." --Hope H., California

WHY DO WE HIGHLY RECOMMEND THE NEW PATENTED PURE-LIGHT TECHNOLOGIES ANTI-BACTERIAL BULBS? Here at the West Clinic we have some of the sickest people in the world walk through our doors. We have been searching for ways to limit bacteria and viruses, to protect our patients, their family members and our medical team.
What we found are two revolutionary new products, PLT (Pure-Light Technologies) anti-bacterial light bulbs and anti-bacterial wipes.
According to the manufacture they have been proven to kill 99.9% of bacteria, viruses, fungus, and mold… including MRSA, E-COLI, STAPH, CRE, Salmonella and other diseases...even those viruses and bacteria that have become resistant to antibiotics. Additionally, the Pure-Light light bulbs last up to 20,000.00 hours and the antibacterial wipes for one year.
All we did is replace the light bulbs in our clinic with the new patented Pure-Light anti-bacterial/anti-pollution/anti-allergen light bulbs, and use the new Pure-Light anti-bacterial/anti-allergen surface wipes. We wipe down everything…our counters, door handles, light switches, faucets, and medical equipment, everything that will help reduce bacteria or viruses.
Besides adding the anti-bacterial and anti-allergen protection, we find that odors are reduced and surfaces are easier to clean.
We are using the Pure-Light anti-bacterial light bulbs and surface wipes because we want to:
Protect our patients and their families
Provide a safer work environment for our medical team
Have a cleaner, fresher smelling facility
What we discovered is an economic way to provide added protection for healthier, happier patients and that gives us added peace of mind.

PURE-LIGHT INDUCED REDUCTION IN MOLD COUNT AND ENHANCED GROWTH IN BARLEY GRASS RESEARCH REPORT
Using high efficacy LED grow lights, barley sprouts were grown from seed to harvest using the Pure‐Light coating on the grow light lenses with a control group grown under identical conditions without the Pure‐Light application.
ANALYSIS: With Pure‐Light ‐ 129,908 colony forming units per gram Without Pure‐Light - more than 626,632 colony forming units per gram Use of the Pure-Light resulted in a reduction in mold/yeast counts of almost 80%. At the time of harvest, the test group had roughly twice the sprout height of the control group.
CONCLUSION: Pure‐Light coating offers significant benefits such as enhanced growth and improved control of mold while sprouting grains such as barley grass.
