There are the same actinics on in each of these pics, so the difference you see is all HQI.
SPS Blue Life 14k 150 watt, ~2 months old.
Phoenix 14k 150 watt, ~1 month old.
Without Actinics the SPS is much too yellow for my taste, the Phoenix presents much more crisp white. Actinic support pushes it into the blue look that my tank has.
