Difference in Color temp between 150 w Phoenix & 250 w Phoenix

[koral_lover]

I know ballasts can impact this quite a bit, but generally are the 150 watt Phoenix metal halide bulbs the same color temp visually as the 250 watt de version? Or is the 250 watt version a little whiter? Thinking of upgrading to bigger fixture, but trying to match a 250 de bulb to my old 150 phoenix bulb colorwise... thanks
