PC Lighting.

[qsails]

I have 2x36W PC Lights over my 18 Gallon. The Lights that came with the hood are a 7,100 white and a 12,000 Blue.

My question is should I switch to 2 50/50 10,000 daylight and actinic or should it be, 1 10,000 Daylight and 1 Actinic?

Or am I safe to wait and change them when these bulbs start to Die?

I would stick with what you have until it's time to replace them. I usually go with something between 6500-10000K with an actinic, FWIW.
