Ok, well I like the look of LED
's to but just so you know what you are buying they do not add any benefit for the corals, they are purely for enjoyment purpose.
The reason PC
is incorporated into a MH
is to add acintic supplementation if you use white bulbs.
Being that said the reason I recommended pendants was purely because you can save a ton of cash and have a great MH
setup with a nice blue tint. You can rest a pendant right on wood above a tank if needed.
As far as all in one fixtures, there is nothing wrong with them at all, just very expensive with the same results.
