There's nothing missing but you get more usable light and wider spectrum growing with LED's and you need to adjust accordingly.
Wider spectrum with led is not entirely true. In your standard growlight there is very little outside the standard range of blurples: 450nm - 660nm. Yes, there are some light that throw in a a smidgen of far red but usually its so low in coverage between 660 and 700 that you cant really count it in comparison with the coverage between above mentioned peak. EVO sammies goes a bit further but in most cases 90nm of 300 total in the range of 400-700 is almost completely uncovered. If using extended par range this grows even further. Some of the best parts of the spectrum is right there at those ends and i feel its a misstake to just skimp out there; theres almost a 3rd of the visible spectrum and even more of the bio reactive spectrum left out...
