Frequently Asked Questions



How does it work?


1 - Must the light be on for the bulb to work?
 
The light must be on for the bulb to work. It takes about 45 minutes once the light is on for the photocatalytic action to start i.e. for the super-oxygen molecules to start to be made.

2 - Can the 9 watt bulbs be used with a 3 -Way or Dimmer switch?
 
No. The 9 watt bulbs should not be used with a 3 Way socket or dimmer switch socket.
We sell dimmable bulbs and 3 way bulbs. 

3 - Will an air fan help the photocatalytic action?

The air naturally circulates near and around the bulb. The super-oxygen molecules spread out from the light bulb to a distance of approximately 8 feet. The closer things are to the light the better for the photocatalytic action. A fan is not necessary in order for the photocatalytic process to work.

4 - Can the bulbs be used inside lamp shades?
 
Yes. The air does need to be able to circulate around the bulb, which at the same time, allows the Super-Oxygen molecules to circulate out also.

5 - Will more bulbs increase the effectiveness of the photocatalytic process? 

Yes. Two to three of the 9 watt bulbs work best in a room 15 ft x 15 ft (average kitchen size). The more bulbs the greater the area covered by the photocatalytic process.

6 - Must the light bulb be in the open air to work?

Putting bulbs in a sealed cover will only be effective for the air inside that cover. They must be open to the air of the room they are in for the photocatalytic process to have its greatest effect.

7 - Are PLT lights classed as full spectrum daylight color lights?

Yes. Because they are full spectrum and the same color as natural daylight, they have all colors with emphasis on red, yellow, and green light (between 480-680 na wavelengths).

8 - What are the long term benefits of Pure-Light TiO2 Super Oxygen technology?

We believe that Pure-Light is a part of the holistic answer to our current toxic life.

Let's talk long term benefits of Titanium Dioxide Photocatalytic action.  TiO2 has been around, oh, ever since God created the earth (or, if you are a Darwinist, a whole lot longer).  It has been  "Nature's" Primary way of cleaning and detoxifying the atmosphere from harmful and deadly chemicals, gases, bacteria, molds, and viruses.  It's one of the main reasons that we are not surrounded by toxic fumes and deadly diseases.  There are scientists that would venture to say TiO2 is the primary reason, even superior to the cleansing of the atmosphere by plants.

One of the big problems  we have with our current buildings, is that we make them so air tight, that the toxins that we have brought into the house can't get cleaned by the outside TiO2 Catalytic action.  So we seal ourselves into our homes and businesses with our toxic fumes, molds, viruses, bacteria, etc. and we wonder why we are sicker today than our great grandparents were who spent most of their time outside in the clean fresh air, air cleaned and purified by the TiO2 photocatalytic action. In essence, all Pure-Light is doing is bringing a little bit of natures detoxifying system into our homes and businesses to help clean the air we breathe. 

9 - Is blue light or ultraviolet light bad for your health? 

The answer is it depends on what type of ultraviolet or blue light and how much.

Generally, too much ultraviolet light is not good, (see #11 below), but on the other hand humans especially need some ultraviolet light to produce vitamin D. Vitamin D (or Cholecalciferol) is essential for the absorption of calcium in the intestines.  The major source of Vitamin D for humans comes from the skin, where sunlight converts 7-dehydrocholesterol into Vitamin D. Further modification in the liver can convert Vitamin D into Vitamin D2 (or Calciferol). The conversion of 7-dehydrocholesterol into Vitamin D requires ultraviolet (UV) irradiation between 275 - 310 nm (nanometers: 1 nm equals 1 millionth of a millimeter); however, Vitamin D is susceptible to degradation from UV irradiation between 260 - 290 nm, so the optimal wavelengths for Vitamin D production are between 290 - 300 nm, or what is often termed as UV-B light. 

In other words, ultraviolet light at around 300 nm (UV-B) is essential for human health, but higher frequency UV light above 280 (UV-C) is harmful and in high concentrations can be deadly.   Note: UV-A (315 nm-400nm) is visible, and is often referred to as "black light" or the "purple" light that is often used in special effects.

10 - How does Pure-Light compare against Ultraviolet Light Sanitization?
 
Pure-light makes no claims concerning being used as a treatment or cure of any kind for any disease.
 
Pure-Light is the only light that uses Super-Oxygen technology, where actual super-oxygen molecules are produced by the bulb.
 
It is the Super-Oxygen molecules that provide the sanitizing action, not the light itself.
 
Pure-Light bulbs and technology do not produce, use, or need to use harmful ultraviolet light.
 
Strong ultraviolet light (UV-C or UV light higher than 254 nm), especially in excess, 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 sterilizing action in some instances. 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 light "contacts."  Bacteria in the shadows are not affected by ultraviolet light.  
In comparison, Pure-Light distinguishes between good "cells" and bad "cells" having an effect only on bad cells.  Additionally,  plants love the super oxygen and grow faster and healthier with it's presence, and the Pure-Light action can sanitize deadly bacteria hiding in the shadows. 
"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. 

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. 
The light initiates a reaction between two molecules of thymine, one of the bases that make up DNA. UV light at this wavelength (shortwave UV or UVC) causes adjacent thymine molecules on DNA to dimerize. The resulting thymine dimer is very stable. If enough of these defects accumulate on a microorganism's DNA its replication is inhibited, thereby rendering it harmless. 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. 
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. And although UV light is also harmful to people (it damages our DNA too!) - as long as we stay out of direct exposure - it is possibly a better alternative to some of those other nasty chemicals out there."

11 - Are LED lights bad for my health? 

No. Pure-Light Technologies recommends having a healthy balance of natural sun light and LED Pure-Light for best overall health.
Our Pure-Light LED lights are full spectrum, having red, green, as well as some blue frequencies present.
Our simple quest is to seek after and produce the best and healthiest lights we can.   

12 -Why do plants grow so well with Pure-Light Technology?

It is primarily because of the extra oxygen that the technology produces along with the discouragment of harmful bacteria and mold.  Plants need oxygen to actually grow and survive.  This article from the University of California at Santa Barbara helps explain it.

Why do plants need oxygen?  

Answer Part 1:  I'll bet you are wondering that because you already know that plants can make oxygen. You probably already know that in photosynthesis, plants take CO2 from the air, Water (H2O) from their roots, and energy from the sun and make sugar (C6H12O6). What a lot of people don't realize is that when there's little or no light, plants do the same thing we do. The break down the sugar to release CO2, water, and energy. This requires oxygen. The reason is pretty complex, but basically, electrons get passed around, and oxygen has to pick them up at the end of the process.  If you measured the amount of oxygen and CO2 dissolved in a lake, how do you think the daytime levels would compare to the nighttime levels?   Would a plant need oxygen if it were under lights 24 hours a day?   

Answer Part 2:  Plants respire, just like we do. When a plant doesn't have access to light, it burns sugar to make energy, consuming energy. It's just that plants use sugars to build their bodies as well as an energy storage, so over the course of a plant's life, as it grows, it makes more sugar than it burns, and so releases more oxygen than it consumes.

Answer Part 3:  Plants need oxygen for the same reason you and I do -- without oxygen we can't convert the carbohydrates, fats, and proteins we eat into energy. We call this process respiration, and the formula for this sort of reaction is like this:     sugar + oxygen --> carbon dioxide + water + energy

So we breathe in oxygen and eat food, and we exhale carbon dioxide and excrete water.
This exact same reaction goes on in every living cell, including all plant cells. But of course plants don't have to eat food, because they make their own food using photosynthesis. The formula for photosynthesis is basically this:

carbon dioxide + water + sunlight --> sugar + oxygen

You can see that this is basically the reverse of respiration, but plants convert the energy in sunlight into the chemical bonds of the sugar. When cells respire, they break those bonds and get the energy out of them.Anyway, you can see that photosynthesis produces oxygen as a waste product, so for the most part plants don't have to breathe in extra oxygen -- they can just use the oxygen that they produce during photosynthesis. However, plants only perform photosynthesis in the green parts, like leaves and stems, but all plant cells need oxygen to respire. Cells in the leaves get plenty of oxygen from photosynthesis, but cells in the roots often need to get oxygen from the environment to stay alive. Even though roots are buried, they can absorb oxygen from the small air spaces in soil. This is why it's possible to 'drown' plants by watering them too much. 
If the soil is way too wet, the roots are smothered, the roots can't get any oxygen from the air, and the cells in the roots die. Without those root cells, the rest of the plant dies. Some plants have evolved adaptations to deal with extremely wet soil. Mangroves are trees that live in swampy environments along the coast in the tropics. The roots of mangroves are often entirely under saltwater, so they have special structures called pneumatophores (Greek for "air carrier") that act like snorkels, sticking up out of the water to get a oxygen for the roots.
