Hamilton Reefstar or Reef Optix III

[Willito]

I am having a hard time deciding which of the two HQI pendants would do a better job of spreading light. I plan on putting 2 pendants over a 4' tank and I dont want the spotlight affect. The Reefstar is L16.5"xW10.25"xH3.5 w/hammer tone reflector and the Reef Optix is L11"xW 9"xH 4" w/polished aluminum reflector. With the differences in dimension and reflectors, will one spread the light better than the one (same ballasts/bulbs). Any inputs?
