Yellow Acro Under MH?

[denverjon]

I'm thinking of buying a bright yellow mille from a local reefer but I'm trying to figure out whether the acro will hold its yellow under metal halides? I've got 250w 20k Radiums supplemented with T5's and LED's.

Sure this is Copps 24k milli under halides and blues in my tank

Have had a yellow in the past and light green milli now under 150w halides without any color retention issues
