Go Ahead And Turn Out The Lights

The Litro Glow Lamp was initially created to pursue health measures and alleviate side effects of hindrance to sunlight.

Through trial and tribulation, we have created the ultimate in lighting. The lamp itself ascertains benefits never associated with traditional lighting.

It is the first and only lamp that Glows after power interruption! The only lamp being implemented into schools, hospitals, hospice care, and the testimonials are outrageous!

We have just introduced Litro Glow Lamps into a world study to examine the actual clinical trials and effects of our lighting and children with autism.

Children being submitted to Litro Glow Lamps are actually seeing ADD, ADHD, and Autism symptoms alleviated!

Teachers and professors all around the world testifying to the wonderful health effects being associated to the introduction of Litro Glow Lamps in their teaching environments.

Our lamps are currently being tested by numerous utilities, and with in the next thirty (30) days we will have an Electrical Utility Company mandating the use of Litro Glow Lamps. Litro is becoming the ultimate in energy savings as well!

With the introduction of Clean Spectrum lighting (almost the perfect simulation of sunlight), this enables Litro to install and replace current fluorescent lighting at a 1:2 change out ratio. That’s an immediate 50% energy savings!

Not to mention that Litro T-8 has a line run watt rating of approximately 24-26 watts.

Testimonials have shown as little as 19 watts to run our lamps! Traditional T-8 lamps utilize 32 watts, have a very low light output, normally a 3000-4000 K spectrum being emitted. This emittance is the same that causes migraines, side effects of all kinds, not to mention seasonal affective disorder (SAD), and the over-all general feeling of a drain on your life.

Litro Glow Lamps can achieve health and energy savings mainly due to the Special Proprietary Phosphor Additives. These additives have allowed the magnification/manipulation of the light emittance to allow the incredible energy savings! We have also increased the filament sizing in either end of the lamp to accommodate not only 120V but 240V as well, making for a very versatile lighting source around the world.

Recently, we discovered that Litro Glow Lamps not only benefitted people, but plants as well! Talk about the greatest discovery! Our lights are proven throughout the grow industry to be the most energy efficient lights ever introduced into

Indoor Grow, Commercial Grow, and not to forget the ideal way to grow for hospice care patients, to get their Litro Therapy will they are taking care of their personal plants! It’s a win-win situation.


In any type of power outage, power failure, the lamp has been implemented with a special phosphor to emit a bright Blue Glow in the event of power failure. Employees and customers can be in many different places in a building when an emergency strikes. Offices, restrooms, basements, parking garages, hallways, elevators and storerooms are just a few examples. Battery powered backup lighting systems may work in these areas but are very costly. They need maintenance, and even then, they can still break down. In the event of an explosion, they can fail. EAL lamps are an added measure of safety and protection and can be economically justified in areas where costly battery backup emergency lighting cannot. With EAL lamps, you can always count on them to emit light.

EAL combine a high-spectrum, scotopic-rich phosphor blend with a strontium aluminate (non-radioactive) after-glow phosphor blend in a discharge fluorescent tube. EAL lamps have been designed to maximize and compliment the eye’s ability to see under low light conditions. The combination of this scotopic-rich phosphor blend and the afterglow phosphor blend compliment each other in many ways: visual acuity, scotopic eye response, high-spectrum color correctness, melatonin reduction, energy efficiency, and quicker emergency response time in low light levels.

The EAL afterglow phosphors are fully charged in just 15 minutes and partially charged immediately when turned on. The afterglow light output will continue for a period of time after power is cut off (approximately 20 minutes of higher intensity glow and up to 12 hours of lower glow). Even if the lamp is broken and the gas is released, the pieces on the floor will continue to emit light, maximizing this emergency lighting lamp to its greatest potential. The lamp, when charged, can be removed from the fixture and will continue to glow, and can be used as a portable emergency light source.

Clean Spectrum Emittance

Clean Spectrum refers to the closest man-made simulation of Natural Sunlight. All lighting presented by Litro Technologies is Clean Spectrum/Clean Series. When in discussion of health benefits referencing Litro Glow, Clean Spectrum has the optimal integration into the Medical Industry. It has been well documented in doctor’s offices, hospitals, classrooms, office environments, etc. to the health benefits of Clean Spectrum introduction.

Why Clean Spectrum?

Clean Spectrum lighting nourishes every living organism on Earth. Today, people are spending more time indoors and not getting enough sunlight. To achieve the needed balance of sunlight, lighting needs to emit a Clean Spectrum of color as well as infrared and ultra violet wavelengths. These specifications are absent from regular fluorescents. All Litro lamps contain these essential ingredients to achieve the balanced lighting of your body needs. An initiative presented by Pacific Gas and Electric Company has shown the correlation between occupant productivity, to the exposure of sunlight.

The study demonstrates increased retail sales (up an average of 40%), and better schooling test performance (up an average 10-20%), when exposed to our technology. This indicates a clear direction to model our future building endeavors. Daylight/Sunlight design, when integrated into building architect, is the single most powerful strategy to reduce energy use in commercial and institutional buildings (from 30-60% reduction).

Clean Spectrum Lighting In Schools

A 1999 study examined the effects of natural and artificial Clean Spectrum lighting on student performance. This study was performed in three elementary school districts-one each in California, Washington, and Colorado. Each district has different curricula and teaching styles, different school building designs, and of course very different climates. In spite of these differences, the results of the study showed consistent positive, and highly significant effects on student performance.

Results from the school districts are as follows:

  • California: 20% faster progression in math, and 26% faster progression in reading.
  • Washington and Colorado: Anywhere from 7- 18% in the same progressions.

Clean Spectrum Lighting In Healthcare Environments

People under increased stress require more sleep, and sleep deprivation has been described as a stress factor that may interfere with recovery from disease.

The Health Systems throughout the world have known that Light Box technology has proven to enhance mood, as well as recovery/rehabilitation time. There are companies that offer a Light Box Technology, enabling patients to receive Clean Spectrum rehab during office visits. Until now, this technology has been only attributed to a small number of health care organizations, mainly due to cost.

What is Color Temperature?

The color temperature of a lamp (bulb) describes how the light appears when the human eye looks directly at the illuminated bulb. A unit called the Kelvin (K) measures color temperature. The Kelvin thermodynamic temperature scale is defined so that absolute zero is 0 kelvins (K). (Note: The Celsius and Fahrenheit scales are defined so that absolute zero is −273.15 °C or −459.67 °F). Imagine heating a bar of steel and observing the color of the bar at increasing temperatures. At some point the bar will appear to glow a dull red. As heat is added, the dull red turns to yellow, then to white, then to bluish white, finally to blue.

A light bulb that produces light perceived as yellowish white will have a color temperature of around 2700K. As the color temperature increases to 3000K – 3500K, the color of the light appears less yellow and whiter. When the color temperature is 5000K or higher the light produced appears bluish white. The color temperature of daylight varies, but is often in the 5000K to 7000K ranges.

When the desired lighting effect is “warm”, use light sources in the 2700K – 2800K range. Most common incandescent light bulbs will produce light in this color temperature range.

What Color Temperature Simulates Daylight?

To give the perception of daylight (bluish white light), use light sources with a color temperature of 5000K or higher.

It is important to note that color temperature is not the same as color rendering. The color temperature of a light source does not describe or predict the ability of that light source to render color accurately.

What is Color Rendering Index (CRI)?

Color rendering describes how a light source makes the color of an object appear to human eyes and how well subtle variations in color shades are revealed. The Color Rendering Index (CRI) is a scale from 0 to 100 percent indicating how accurate a “given” light source is at rendering color when compared to a “reference” light source.

The higher the CRI, the better the color rendering ability. Light sources with a CRI of 85 to 90 are considered good at color rendering. Light sources with a CRI of 90 or higher are excellent at color rendering and should be used for tasks requiring the most accurate color discrimination.

It is important to note that CRI is independent of color temperature.

To further understand the physics of color rendering, we need to look at spectral power distribution.

What is spectral power distribution?

The visible part of the electromagnetic spectrum is composed of radiation with wavelengths from approximately 400 to 750 nanometers. The blue part of the visible spectrum is the shorter wavelength and the red part is the longer wavelength with all color gradations in between.

Spectral power distribution graphs show the relative power of wavelengths across the visible spectrum for a given light source. These graphs also reveal the ability of a light source to render all, or, selected colors.

The most obvious difference is the generally lower level of relative power compared to daylight. The 3000K lamp has a CRI of 82. It produces a light that is perceived as “warmer” than daylight (3000K vs. 5000K). It’s ability to render color across the spectrum is not bad, but certainly much worse than daylight. The 5000K lamp has a CRI of 90. It produces light that is perceived as bluish white (similar to daylight) and it does an excellent job of rendering colors across the spectrum.

Health Benefits from Sunlight

In moderation, sunlight improves your immunity, prevents disease, increases intelligence, stimulates your metabolism, and boosts your energy level.

Specifically, the full spectrum of the sun’s light rays has been shown in medical and scientific studies to:

  • Positively influence your risk of getting sick (there is a preponderance of evidence suggesting that decreased sun exposure is closely related to your risk of acquiring the flu, a common occurrence particularly during the colder months)
  • Lower blood pressure
  • Improved mood
  • Enhanced mental awareness, concentration and productivity
  • Superior visual clarity and color perception
  • More energy
  • Reduced eye strain and fatigue with a glare-free and comfortable reading environment
  • Greater learning ability and intelligence

The problem is that getting adequate sunlight isn’t easy these days. Most of us suffer from “sunlight starvation.” We all need about one hour of unfiltered sunshine each day. Unfortunately, the majority of people even come close to receiving that amount.

An important goal of lighting practice is to provide environments that appear clear and crisp. This means that the edges of viewed objects should be well enunciated. It is not optimal just to see the objects, but to see them sharply enunciated. It is these object edges that contain high spatial frequencies and where acuity is essentially the measure of visual sensitivity. Thus, all lit environments will be optimally viewed when acuity is best.

Studies have shown that at a given value of light level, acuity is best when the lighting spectrum has high color temperature. Since acuity generally decays with age, it is possible that the effects observed here could be more dramatic in older persons. It has been noted that lighting retrofits replacing 3500K lamps with 5000K+ lamps have been carried out in many commercial and industrial environments where both major energy savings and improved vision have been reported.
Fifty years ago, the most common fluorescent lamps were cool white (4100k color temperature and 65 CRI color rendering index), which is a color of white light having a distinct bluish-white tint. And, with a color accuracy of 65 (out of 100), people disliked them, and skin tones looked pale under them.

Growth Enhancement

With the benefit of Clean Spectrum, plant/vegetative growth now can be accomplished with a plug and play option of our Litro Glow’s. They are the only lamp on the market with the Growth Effect, in addition to all above mentioned features. A T-8 format to allow residential/commercial OEM change over, with minimal expense.

Just think of a grow environment in your basement, garage, or anywhere that this accomplishment could have never been ascertained without buying a special purpose grow-light. The drawback of most of these lights vary from very expensive, very short life span, and just generally lacking the punch to properly perform to most needs.

The following example is a Cost Savings analysis based on a change over to Litro Glow:

A parking garage utilization of 7000 regular T-8’s changed out annually.

  • Energy cost: With implementation of our special phosphor blend, illumination is greatly enhanced, presenting a 1 to 2 change out ratio. In some circumstances, certain establishments have gone as far as a 1 to 3 change out. This basically proves to be roughly a fifty percent energy savings mechanism as well.
  • Maintenance cost: Roughly 2 lamps per hour change out, $10.00 per hour charge equating to $35,000.00 per year in maintenance fees.
  • Disposal cost: Disposal rates range from $ 0.65 to $ 1.00 per lamp, dependent on the state equating to $7,000 per year in disposal fees.

As mentioned previously, Litro Glow has a projected life of 36,000 hours, roughly 3 to 4 times longer than typical inexpensive commercial fluorescents. When equating cost savings, Litro Glow’s will only require one change out per 4 years, versus 4 change outs of the inexpensive commercial fluorescents.
