Not powerful enough for nems. You can do soft corals and lps corals. Not sure it would be able to handle any SPS corals as this light has about 400 par at the waters surface, but as soon as you dive one to six inches down it drops dramatically to 120-150 par and from 6 inches to 9 inches it goes from 120-70. Which is again great for LPS and soft corals, but not enough for SPS or nems. https://current-usa.com/wp-content/uploads/2017/02/Orbit-PAR-Measurements-1.pdf
Here's my old set-up standard 29g with Current Orbit only- mostly LPS, Softies and couple easy SPS placed near the top.
I am not sure how is your tank is set-up, maybe add dual t5's for the Nems?
