I really dislike these LED vs M/H vs T5 battles, which wasnt even what this thread was about lol, but when i hear lines like that, well then that's fine if you just want decent and something to work well. The main theme here is the guys that defend M/H and T5s are usually the guys growing SPS or Acro dominant tanks and dont want to settle for "decent", or for "grows coral fine". They're growing Acros, usually high demanding ones, not zoas, or euphyllia or mushrooms and they are not looking to compromise one ounce with things like spectrum, blending, spread, output.
