50/50 lights?

[dolph]

What are 50/50 vho lights? I know what vho lights are, but 50/50?

Also, I currently have 2 110w vho super actinics on an icecap 660. Could I run 2 160 w super actinics instead?

50/50 lighting is a mix of 50% actinic and 50% 10,000k. No matter what system (VHO, NO, PC) its all the same as the mix if its called 50/50.

As far as the different bulbs, heres what I found:
