Success with LED and SPS

For full spectrum, it should be 5:2:2:1 RB:NW:TV:RGB for full spectrum. True violet (405nm) actually pops up a lot of colors that RB:NW cannot and it triggers a specific region of photosynthesis too. UV (390nm) on the other hand, is actually bad, possibly because the wavelength gets shorter in water from the source.

And this is coming from your experience with LEDs?

Nope. Researches from nano-reef led full spectrum thread
