You went with 400w is that considered a big, medium or small fixture for your tank? I cant remember what he said he had. Definitely not 250w thats for sure hahaAny metal halide fixture will work.
Fixtures like lunembright and lumenmax that I have put down more par than grow lights due to their angled reflectors.
The Reef Brite is the only new one in the US marketed for reef tanks.
Only way to tell is try them.
You won't be disappointed either way.

he offered me a few last year, I just shot him a message asking if he had any and what wattabe they were
