I'm not really sold on the UV yet, but I am still researching it.
I started looking into the UV lights, (UVA AND UVB) I already have the UVA and UVB bulbs for the the turtle tank, but want to see if I can incorporate them into the grow table as led's.
What do you think about these? 395nm - 410nm

I've been researching UV-A and B also. I watched a video of a guy who did a comparison of a few different ones and his suggestion for the best one of that group was this one:

And everyone says the UV's will burn up your plants, so you have to put them on a timer and only give them about 15 minutes, twice a day. Read the Amazon reviewers comments on that. Also it has to have a good metallic reflector, so I ordered this fixture for it:

Also note that LED's are directional, they send out a narrow focused radiation. So if you have one LED strip, your light coverage will not spread out sideways, it will shine straight down in a narrow band. In order to get good canopy coverage, you must have several of them side by side.
I've been following Dr Bruce Bugbee who is a scientist that has done research on lighting for NASA. He has many youtube videos you can watch. Here's a general discussion of his, with the guy that did the comparison of the UV Tubes.
