So I am getting ready to replace my PC bulbs in my current light running 4 65 watt and was considering a different direction on the light spectrum I current have 2 10k bulbs and 2 actinic. I was looking to get a bit more "pop" so was thinking of either 2 50/50 bulbs 10K/460nm and either 2 420nm or another 2 460nm. to enhance the blue a bit more.

This is my last time to replace the bulbs before going to either T5 or LED but its just not in the budget to replace the light now so I am trying to optimize what I have.

What are your suggestions???
