I am not exactly sure how strong the lighting is(don't worry I am not buying any corals until I understand the lighting part better) but the friend that gave it to me said it is strong enough for soft corals. I have to look into the strenght of the light before I purchase anything.
I think the issue with the sfe not being "reefsafe" is that it will eat other small animals like shrimp, crabs, and fish. I don't think you would have to worry about it eating your corals.
