Hello Everyone,

As the maker of the “ALTA LED FULL SPECTRUM COB PRODUCT LINE” I am reaching out to all of you with this information below that is vital in the decision making of what technology to choose when growing organically.

I have blind copied over 100 people on this email that includes grow engineers, lighting specifiers, growers, green house manufacturers, energy engineers, magazine editors, and so on.


There are a lot of different measuring devices people use to make their decisions about growing such as MicroMole Meters, Par Meters, Lumen Meters, Footcandle Meters, and so on. All of these meters or techniques were made to measure light sources that are being used for growing and layout and design. Alta is an innovator, so more than likely, there has not been a meter made in the world that gives you the specific things that we produce. For instance, a Par Meter takes a reading of spectrum from 400-700, so if you are basing your decision on amount of PAR this is misleading. Because we know that the plant growth needs the spectrum from 400-800, and 600-800 being the best area for growth in the cycle, then a PAR reading of 560 might have a lot of intensity but the green and yellow part of the spectrum does us no good. You do not want all the intensity in the yellow and green spectrum, you want it in the orange and red for results, so basically the reading you ware getting is with the furthest spectrum green diode, but giving the results and energy that does not enhance the growth cycle of the plant. MicroMole readings will measure the amount of radiation and energy but is it necessarily measuring the nanometer range of the color spectrum that is needed. Lumen and Footcandle outputs are for the lighting industry mainly, they will show how many pieces of light is emitted and how much light in general is hitting the surface, but will not tell you what you need to grow plants. It is all about What Colors in the full spectrum you are the best at without drop offs/peaks and valleys, continuous nanometer results throughout the complete spectrum like the apogee tests attached.


Please do not base your decisions on the amount of LIGHT, the amount of PAR, the MICROMOLE Readings. You should be basing your decisions on the amount of the correct Light, the correct color spectrum of PAR, and the correct Color and Intensity and Radiation to grow whatever you are growing. We know that growing Cannabis requires high intensity, high radiation, and lots of spectrum from 600-800 to flower with high yield and results. But we should remember that the more of these 3 areas even to Vegetables and Flowers will just mean the same as giving it more Sunlight, which will increase your results either by finishing your grow cycle faster or by giving you more yield.


Alta LED feels very comfortable with their position in the grow industry. We have reached out to all grow fixture makers whether it be HID or LED types of lighting to ask them to provide any test results third party that would be good enough to advertise, we have yet to find one in a worldwide search. If there is any published test results with a complete full spectrum from 400 – 800 we would like to see it.

The reason I say the above two sayings is because Alta LED is 1 of only 8 Diode Technologies in the world today. We are privately held and Made in the USA. Since we are at the creation level of making light out of nothing, we constantly put the R&D into areas where nobody has ever gone, or where our competitors cannot go. Out of all the LED’s we see in the world today, it all originates from 8 technologies, 7 of these companies create Diodes the same way but with different materials used so they don’t infringe on each others patents, then the 8th is Alta which has its patents in an area called “Nanolithography” which is patternization and the ability to do things in the LED industry that have never been done. The other 7 technologies (Osram, Lumileds, Cree, Nichia, Toyoda Goshei, Samsung, and Epistar) use the term random patternization which means they have a wider range of binning than Alta. A wider range of Binning means that their inconsistant forward voltage will not allow them to duplicate diode nanometers in mass quantity. Having all the blue diodes with the same nanometer is vital in the consistant spectrum performance when growing.

When you give photons a path to emit rather than forcing them out, you increase the level of light and at the same time you decrease the heat per 1 watt used. This is why Alta is able to make Color Corrected chips with the standard blue Diodes, all the same nanometer, along with our patented secret sauce to give the world a full spectrum chip source that has the following characteristics.

These points below will never be matched in the world since the other 7 technologies will not be able to do this. If it was able to be done, RGB would have been gone along time ago.

Up to 500W in a single chip, Diode area 3″ diameter (Replacing 1500W HID Lighting, and 1500W Tungsten)

3200 Kelvin, 94 – 100 CRI, the higher the CRI the more expensive it is (Remember the Sun is 100 CRI)

5600 Kelvin, 91 – 95 CRI, highest level ever known with white light, color correction, to replace Metal Halide

Nanometer Range for Growing from 400 – 800, (Remember for Growing Blues and Reds are what is needed)

Full LED Life – 5 year warranty, estimated life is 8 years

Full Spectrum, Radiation Levels, Intensity (These 3 Areas gives Alta the advantage)

I want to now compare Alta Technology against the other sources of Grow fixtures commonly used and compared against:

600W Full Spectrum High Pressure Sodium

Pros & Cons 600W

Pros – Inexpensive
Pros – Does a good job for low level vegetables, and flowers, (Flowers and Vegetables do not need the intensity)
Pros – Easily replaceable
Cons – Color Shift within 6 months to 1 year, spectrum is shot, replace bulbs
Cons – Main Light Bulb makers still get lamps from China, no really great proven lamp for color correction over time
Cons – Nanometer level is mostly between 5,000 – 6,000 which is not really what the plants need, wasted energy, but will still work with Vegetables and flowers
Cons – Hazardous waste, dirty technology, will not be the answer for future programs
Cons – High Labor since life expectancy is not more than 1 year
Cons – Limits alternative energy projects because of the wattage used

RGB LED (Mixing Red/Green/Blue Diodes to make the best Spectrum possible)

As a maker I know what color Diodes will give you the best useable spectrums for lighting. Green Diodes have the furthest spectrum (example: If you have an aircraft carrier off the shore of Iraq, you would shine the green color for the troups to see you)
Blue Diodes have the most useable spectrum (Commercially used in the lighting industry today)(example: Blue Diodes with yellow phosphor makes white light, this is what the combo is for commercial use)
Red Diodes have the shortest spectrum(example: If you have an aircraft carrier off the shore of Iraq, and you only want the planes to see the shipand not the enemy on shore, you would shine the red color) Mixing these 3 diode colors is what scientists have been doing for years trying to get the best color spectrum for growing. Unfortunately, RGB will never be the answer for the grow industry. When growing plants all the way up to growing cannabis, you need a combination of color radiation, and intensity.

Lets break it down what is needed:

For Flowers and Vegetables, the color spectrum up to 650 will work, radiation and intensity needs to be mid range.

For Cannabis, the color spectrum needs to get more into the reds and up to 750, with high radiation and intensity levels.Why won’t RGB will never work for everything? The Red Diode is what is needed to grow, but the spectrum for the Red Diode is the shortest. So for growing Vegetables, and flowers lower intensity with a smaller amount of red will work, but not with the results of a source with a lot of red. Just like growing grass with the sun, the more sun the faster the grass grows, common sense. The only way to get the intensity to grow rapidly with the Red spectrum in RGB is to over power it to see intensity for rapid results, but by doing this, you kill the longevity of the LED and within 6 months or a couple cycles, the light out put and intensity has fallen roughly 50-60 percent and now the light is worthless. This is why RGB grow fixtures are mostly only warranted for 1 year, all the technologies for this area of growing are with China based technologies. If you really want to put any RGB grow fixture company on its heals, just ask for an LM80 test, which is the life maintenance test that government and utility projects require to assure the consumer that the life of the LED’s will last for a long time and that the light level will not drop off for a long time either. Alta LED has the LM80 test available for all customers.

Pros – Energy Efficient
Pros – Clean Technology – no hazardous waste
Pros – Becoming more inexpensive, mass produced now in China
Pros – Good for growing low level vegetables, and flowers
Cons – Maximum Spectrum Range up to 650
Cons – Rely mostly on optics to get light to surface, cannot power up for red color
Cons – Short Warranty periods
Cons – RGB Technology needs pulse modulation, which is high speed flickering to save the Diodes Not noticeable to the naked eye, but can interfere with the grow cycle
Cons – China technology, china manufactured
Cons – No maintenance, when light loses intensity, need new light
Cons – Lower radiation and intensity levels

Apogee is a third party test facility located in Utah that has validated the Alta LED Technology and the HP4S series grow fixture. In the attached test results you will find a graph that consists of measurements for every nanometer from 300 – 1100 in the spectrum. There are 3 pages to each file attached that includes the PAR range, photon flux, energy flux. I have included both tests, 3200 Kelvin color that showcases the red spectrum, 5600 Kelvin color that showcases the blue spectrum. They both have their strengths in the world of growing and cover the full spectrum.

In Conclusion, Alta LED is excited and poised to introduce their full spectrum technology to the world. We have conducted private trials for over a 2 year period and now are very confident that the worldwide market will benefit on its results.If you are happy with your Metal Halide or High Pressure Sodium results, performance, and costs then keep using it.If you are happy with RGB LED Style of Grow Lights, then keep using it.Alta is the answer for the consumer that is motivated to go with the newest LED technology, most energy efficient, longest lasting,and American Made. State of the Art facilities that are being built around the world are spending tens of millions of dollars, even though the HP4S series is not cheap, it is the future and the best option.

Thank You,
John Klena
