Which of these LEDs would you choise for an ATS?

I'm at least not zeroing in on roughly what i want lights wise, but there seems to be a great deal of argument about whether some of these arent powerful enough and whether some are too powerful. If anyone could run an expert eye over these choices and recommend one to me i would really appreciate it. Thanks:

Choice number one:

Choice number two:

Choice number three:

I'm using a "choice number three" (nearly). It's doing a good job. It is also bloody bright.

thanks for replys people. for a two sided algae scrubber will i need two of these lights or could i place one above the mesh? im guessing i will need two, but then that will be really, really bright. my scrubber is built from an 18x10x10 inch fish tank, with a wet chamber and two dry for lighting.

thanks
