It will grow anything, assuming you have enough units for tank size.... But that goes for all lights.....
Regarding par, they are in top output in that "90w" class, so no worries there.
Regarding spectrum, well, things are here bit complicated. It is just basic spectrum, ab+ is closest. By all means not bad, nice sharpness, nice colors, just dont expect "image quality" like some high end units have.
These lights are not meant to compete with radions, stratons, hydra, philips and other high end stuff, they simply can't.
But they are great options/alternative for low-middle range lights, they provide all that is needed for growth, coloration and health of corals.....
Being "red sea inspired", they look good, modern, white color is nice touch, for sure best than most, if not all black boxes out there, imho...
Edit: some torches, hammers, etc with these lights..bad quality pics, but good looking corals ;)
