Just my thoughts on the question, the ATI True actinic compliments the 6500k really well and helps tame down the yellow look. That pair goes nicely with the blue plus to cover most of the spectrum.I always run T5’s because I feel it is one of the best light sources out there. I’m my last fixture I ran two 6500’s, but wow it was yellow. So I dropped down to one. Some of these T5’s bulbs have a good range. What are your go to T5 bulbs If you weren’t running MH’s?
