sure thing, the 12.5k i found is a crisp white (at least in my eyes), with 0 tinge of yellow. the stock current 10k was a little too yellow for me, though i think the PAR value on those was very good as corals started to color up intensely. anyways, the 12.5k coupled with the actinic makes for a good combination in my opinion for aestethic purposes. the magnetic ballasts also overdrives bulbs maki
