The only thing I'm a little concerned about is that they seem 'dim' to the naked eye, even when providing more than enough light for corals. I guess I'll see...

UV is defined as 400 nm to 10 nm, so yes 400 nm is UV. I can't find anywhere where Kessil states the wavelengths of their UV component is, maybe you have a link? I can control my UV independently on my Hydra 52s.
