THE SCIENCE AND THE STUDIES

​Though the photocatalytic properties of Titanium Dioxide has been known for many years, it wasn't until NASA helped develop it for use on the International Space Station as an air purification system that it became somewhat viable, though expensive.  Pure-Light Technologies has taken the NASA technology and improved upon it in several ways, and in the process reduced it's cost to consumers.  

The unique action of the PURE-LIGHT TECHNOLOGIES light bulb is that it uses light in a photocatalytic action to continuously create two special types of super oxygen molecules called Superoxide (0-2) and Hydroxyl ion radical (HO) that kill bacteria, viruses, mold, and also break down toxic VOC pollutants. The air that we breathe is full of these bacteria, viruses, mold, toxic pollutants (called VOC--Volatile Organic Compounds like Carbon Monoxide, Benzine, Formaldahyde...)  especially in enclosed areas like hospitals, schools, businesses, and homes looking for a place to land and grow.  As air comes near the PURE-LIGHT coated light bulbs it gets cleansed of these bacteria, viruses, mold, and pollutants. The air also gets deoderized as well.  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 unique photocatalytic phenomenon or action was discovered in 1967.

  • The well known PHOTOCATALYTIC ACTION of TiO2 is such that when light hits it, it produces a special type of excited electron. This excited electron, when it comes into contact with a water molecule, changes the water molecule (H20) into a couple of types of special super oxygen molecules called SUPEROXIDE (O-2) and HYDROXYL ION (HO). These two super oxygen molecules provide a triple "action"... two actions against viruses and bacterias, and another "action" against VOCs.

  • SUPEROXIDE (O-2), or super oxygen (also called hyperoxide), is actually produced in the human body in large quantities by Phagocytes (White blood cells)  and is used by the immune system to kill invading microorganisms.

    Superoxide (O-2) inside the body, or in the air, combines with a microorganism giving it essentially a boost of oxygen. Good cells thrive with the extra oxygen while viruses and bacteria are killed by the extra oxygen.

    Superoxides are also used in firefighterers' oxygen tanks and divers rebreather systems in order to provide a readily available source of oxygen.

    The HYDROXYL ION radical (HO) is often referred to as the "detergent" of the atmosphere because it reacts with many pollutants called VOCs (Volatile Organic Compounds), often acting as the first step to their removal.

    Hydroxyl radicals also attack the porous cell walls of bacteria and viruses which destroys them through the process known as cell lysing. Human, animal and plant cells are “designed” to be in the sunlight and have cell walls that are less porous and are not harmed by atmospheric hydroxyl radicals.

WHAT MAKES PURE-LIGHT BULBS UNIQUE

Though the properties of TiO2 are well documented, there have been problems in the past with applications:

  • The first problem is that the photocatalytic process of TiO2 works well with sunlight or high power UV lights but not with ordinary light. PURE-LIGHT overcomes this by using a newly developed proprietary enhanced TiO2 formulation (Z-TiO2) that works extremely well with ordinary light. PURE-LIGHT TECHNOLOGIES has the exclusive rights to use this new formulation on light bulbs.

  • The second problem is getting the TiO2 to "stick" to a surface longer than a few weeks or months. That is why other companies have tried to do it, but it has not worked very well for them. PURE-LIGHT has developed a new patent pending process that can "seal" the TiO2 to the surface of a light for up to 10 years. Since PURE-LIGHT developed it, no one else has it.

THE STUDIES

We are in the Process of conducting Certified Lab Tests on our products for effectiveness in certain areas.  

1. Pure-Light Study #1: Barley Sprouts and mold  November 2017  

  • Conducted by Sustainable Lighting Solutions Christopher Rakowitz & Ken Chio

  • The purpose of this experiment was to determine the effectiveness of the Pure-Light coating using photocatalytic activation specifically to control mold and yeast on barley sprouts.

  • Conclusion:  Pure-Light Not only dramatically reduced the heavily introduced mold, but doubled the growth of the Barley sprouts.  "The photocatalytic technique appears to be a versatile and efficient disinfection process capable of inactivating a wide range of harmful microorganisms in various media. It is a safe, nontoxic, and relatively inexpensive disinfection method whose adaptability allows it to be used for many purposes.   Mold levels are very significantly reduced under very difficult conditions not normally seen in horticulture. Typical conditions would not promote mold before and during a cultivation period and therefore would never reach levels of mold found in our testing. Under normal conditions, it would be expected from our test results that mold levels would very easily be controlled by use of the Pure-Light coating."​  Click here to read full report.

2. Pure_light Study #2: Pure-Light Effectiveness against E-Coli, Salmonella, and MRSA.  February 2018.

  • "Glass slide and laminated wood flooring coupons were inoculated in triplicate with a suspension of Escherichia coli, Salmonella enterica, and methicillin-resistant Staphylococcus aureus (MRSA). The slides and wood flooring samples were exposed to PURE-LIGHT coated LED light bulbs and tested at 24 and 72 hour intervals to determine organism survival/reduction. Control slides and coupons (not exposed to light bulbs) were also tested at 24 hour and 72 hour intervals for comparison purposes. The glass slide coupons were set on a counter approximately 5 feet from the surface of the lights. The wood flooring coupons were set on the floor of the room approximately 8 feet from the lights."

  • "CONCLUSIONS/OBSERVATIONS: The greatest bacterial reduction was seen after 72 hours of treatment compared to 24 hours. E. coli was reduced by 94.7% on glass and 93.3% on the wood surface after 72 hours of treatment. MRSA was reduced by 80.6% and 80.0% on glass and wood after 72 hours. S. enterica was also reduced but by a smaller degree; 47.3% on glass and 57.4% on wood after 72 hours of treatment."   Click here for full study in PDF Format.
