BS180 or PG180 for Scrog growbox

Guys,
i have small space for one scrog plant. i am planning to do hydro with some led lamp.
distance will be from 12inch (veg) to 6inch (flowering).
question is which one to choose - pro grow 180 is more expensive, but i dont care. my concern is - is it be too powerful for such set up. since it will be only 2.5sqrt f area of illumination.
Blackstar 180 has bad reviews on reliability. i am not from us, so for me it is an issue.
what yeild can i get if i top, lst and scrog after with such led setup. any other ideas if nob of these are optimal. i will buy is us, and ship it internationally.
thanks in advace
