Looking at doing a diy LED mounting bracket above my 55g. I'm looking at purchasing some LED flood lights from amazon for cheap and mounting them myself. Rather new to LED and could use some input on what configuration would be best for my 55g with the intention of growing low to medium light plants, doing ferts and excel with root tabs. Looking at 4 30w fixtures or 4 50w. Any input or tips on this would be much appreciated!
