Rugar89 - I just purchased the Mars Hydro Reflector 192 Light you are talking about. I have it in a 2 x 4 tent with 2 girls growing in a DWC set up. I did the same as you and asked questions before i purchased. You can figure out the whole LED vs Other lights by reading older posts and internet research, but I can say that the light i purchased has worked very well. It runs quietly, there is no heat problems and my girls are now in their 2nd week of bloom. The only difference I have noticed is i add Cal-Mag every week when i use LED lights VS my old T5 or Aerogarden. It may seem like a bigger investment, but it was so worth it. I just flip a switch between veggie and bloom and it runs on my timer perfectly. Plus I got very good input from all the people here that answered my questions and posted before me.
