True actinic light looks very blue, in my experience. Are you sure that your PC light isn't actinic?
I bought a complete kit, they came with 2 10k whites, and 2 "actinics".
My actinic bulbs are not purple at all, they are blue. I bought the Coral Life actinic bulbs
The actinic Coral Life flouresence that I was runnning before where more of a violet than a blue. The pc lights are defenatly blue.
I was just wanting to make sure I did not get jacked around on what I bought. I bought these very cheap on Ebay. The bulbs are labeled 10k, and blue, not actinic. I wanted to make sure that I was getting the blue spectrum that I needed.
