the problem is the size of the box, normally the lamps cover 120x60, 120x120, 100x100 so you would have excess or insufficient light... my opinion is to get a 120x120 and reduce the power by 10% (I have an 80x80 with a light suitable for 1x1, I keep it lower during the vegetative stage but in flowering I can push it to 100% with adequate air circulation) of course quantum board for you needs very well-distributed light
