Strong is a relative term obviously. I mention it only as an example of a device employing UV LEDs that I have encountered. The nail polish it is used with must be cured with such a light as far as I know.
Anyway, here's a list I pulled off an auction site of the LED types used in a "7-band" fixture:

I don't doubt the UV polish, there is a CHEMICAL reaction that occurs. Sort of like photosynthesis... I just doubt you are getting much of the same benefit I discussed above from a "LED ARRAY". Look at SCIENCE SUPPLY UV lamps, you can't even be near them. Check the Advanced Mushroom Cultivation forum for people discussing them at various times to cause MUTATIONS. Anything with real power, they couldn't sell as grow lights for health reasons. Think of a tanning bed . Also last time I checked, Eauction's weren't considered an acceptable scholarly source.

More useful garbage. By the information Messiah No more tests The future is here
Photosynthesis, the conversion of light energy into chemical energy in cells that contain chlorophyll, a green pigment. Photosynthesis occurs in most plants and algae and in some bacteria and protozoans. The process is also called carbon fixation, because it includes the production of carbon compounds that store the chemical energy for use in cell growth. These compounds—mainly sugars and starches, collectively called carbohydrates—also serve as building blocks for more complex foods, such as fats and proteins. For photosynthesis to occur, water, carbon dioxide, chlorophyll, and light are necessary.
The Reactions of Photosynthesis Two main chemical reactions occur in photosynthesis. One takes place only in the presence of light and is called the light reaction; the other can occur with or without light and is called the dark reaction.
The Light Reaction has the following steps:
Light enters a cell and is absorbed by chlorophyll. The light's energy raises the energy level of some chlorophyll electrons, freeing them from the chlorophyll molecules. Molecules of water (H2O) from the environment take part in chemical reactions in the cell. Electrons from the hydrogen atoms in each of these water molecules are attracted to the chlorophyll molecules lacking the electrons freed in step 1. This attraction causes the water molecules to break apart into oxygen atoms, protons, and electrons. The oxygen atoms join together in pairs, forming molecules of oxygen. Oxygen molecules, called free oxygen, are released into the environment. The electrons freed from the chlorophyll molecules and the protons freed from the water molecules take part in chemical reactions in the cell. These reactions result in the production of adenosine triphosphate (ATP) and nicotinamide adenine dinucleotide diphosphate (NADPH2). The Dark Reaction The chemical energy possessed by ATP and NADPH2 is used in making carbohydrates from hydrogen and carbon dioxide. (The carbon dioxide is obtained from the environment.) The carbohydrates then possess the chemical energy given up by ATP and NADPH2.
The generalized, overall chemical equation for photosynthesis is:
6CO2+12H2O + light → C6H12O6 + 6O2 + 6H2O
The carbohydrate in this equation (C6H12O6) is glucose, a simple sugar. Glucose is only one of several compounds that can be formed by photosynthesis.
Importance of Photosynthesis Photosynthesis is the most important chemical process for life. Through photosynthesis, the sun's energy is made available to all organisms. For example, when an animal eats a plant, it obtains chemical energy that the plant acquired through photosynthesis; when a second animal eats a plant-eating animal, it obtains some of the chemical energy that the first animal obtained by eating plants.
As organisms respire, they take in free oxygen and give off carbon dioxide. Respiration is dependent on photosynthesis because photosynthesis is the source of virtually all the free oxygen in the atmosphere and in bodies of water. In addition, photosynthesis removes carbon dioxide from the atmosphere and from bodies of water. If this carbon dioxide were not removed, it would eventually smother the organisms that produce it.
Coal and petroleum, composed of the remains of various kinds of organisms, contain energy that was captured from the sun's rays by photosynthesis millions of years ago.

The missing piece of information is how much UV may or may not be needed for growing peyote. You haven't seriously addressed that question so far that I've seen. The bulk of your OP deals with UV's effects on humans. Are UV LEDs sufficient or do you need something more powerful? Are there even any ill effects at all if there is no UV whatsoever?

Psi, I hate to say it but your being an IDIOT! WERE ALL CONNECTED (YOU, ME, PEYOTE, ANNE, SUPERD, SHROOMERY FAMILY)
Plant pigments effect the effectiveness and light absorption of photosynthesis. Which is why you'll notice someones pereskiopsis has red tips.. The plant is reacting to ITS environment, to survive, because thats what LIFE is.

I can tell it's been a while since I've been out of school because it's taking me several re-reads to truly capture the gist of everything being posted haha. Not that that's a bad thing. It's good my brain is getting a bit more exercise than usual these days. Also helps that I'm no longer baked 24/7 like I was for over 10 years.

Anything in those links in particular that struck you as relating to UV having some special significance? From the graph it looks like UV can be used for photosynthesis but not very efficiently.

Might as well just go ahead and finish it now...
  http://www.biology.iupui.edu/biocourses/N100/ch9photosynth.html
And there's this. http://www.nytimes.com/2013/07/23/science/how-does-a-plant-with-red-leaves-support-itself-without-green-chlorophyll.html?_r=0
"Most plants also have other pigments: carotenoids, which usually appear yellow to orange, and anthocyanins, which are red to purple. One pigment usually dominates. So a plant with red leaves probably has higher than usual amounts of anthocyanins, Dr. Pell said. But chlorophyll is still present and at work.
“We used to think that all fall foliage color change resulted from the revealing of already-present carotenoids and anthocyanins when chlorophyll was broken down in preparation for dormancy,” she said. We now know that leaves actually produce additional anthocyanins into old age, she said.
The evolutionary advantages are not fully understood, Dr. Pell said. One theory is that extra anthocyanins provide shade under which chloroplasts (structures within cells) can break down their chlorophyll, helping the plant reabsorb its building blocks, especially valuable nitrogen. Another theory is that anthocyanins, which are powerful antioxidants, protect the plants in preparation for winter."

I have 150W Metal Halide light bulb combined to 250W High Pressure Sodium when sun isn't visible.. Best would be 600W+600W but I don't need to imitate summer, only this winter I have no possibility to keep plants below +18-20C much.
Metal Halide offers an UV-B Radiation to my plants when I need to try imitate the sun ..Afak HPS should also radiate some UV? Idk for sure..

Also these radiate some heat I need.. and only two bulbs are enough to light whole 5x5meter living room for people and plants. 
It's fucking hard time over winter because sun isn't visible over horizon and fatigue is something most people can't understand..
I have arrange some artificial light for use to keep day light for humans and plants.. 
At 7AM Morning 150W MH light starts and light till 8PM. At 9AM 250W HPS will turn on and goes off at 3:30PM.
It's too much of dormancy light but I should choose, no light at all or as strong as possible, cool temps without no frost I can't use this winter.
My lights caused astrophytum ornatum to bloom accidentally at mid-winter but I missed the flower while I was on the road...
Pretty good results with these lights.. All other trichs have stop growing due to lack of water but this strain doesn't want to stop even I have not watered this for months.
 I know this is etiolated some.. I know also it would grow very pale white ugly tip if I have no lights.
This chilipepper is +2,5meter(8-9feet) away from light bulbs and look what kind of foliage plant have.. Only sun (or more wattage) beat's this light combination in plant cultivation
 Light bulbs are designed to use for plants and this are old tech enough proper bulbs are available around.
Other cacti are just stunted because lack of water and they receive light from light bulbs I have above southern windowsill to mature cacti.. This was my only choice in there arctic cause I can't use +5-10C room.. House building there is different anyway.
Same light technology are used in professional greenhouses and these are relatively cheap price but still consume electricity. Also this same technology lights are used to light our highways and infrastructure in every city because these are enough powerful with output of light also, 600W bulb are best what comes to lux and lumen amount per wattage.
But: Why all professional and commercial plant growers use this light technology in greenhouses and cities are illuminating whole streets, parks, valleys, baseball and football fields all over the globe? Why this tek have not been replaced... Isn't that obvious?
"New technology" used in car industry as front lights of car are basically new 12 Voltage metal halide bulb also.. Who could have seen this happen?
