12000k to 10000k OK?

So right now I'm running an Odyssea 48" 4 65W PC and its time for new bulbs. i dont want to get odyssea bulbs I wanted to get some Coralife bulbs. the bulbs that are in there now are 2-12000k and 2- actinic. All I see is the Coralife has is a 10000k, will this be ok?
Then another site says it has 12000k actinic white bulbs and im just confused, what bulbs should i get, what bulbs do others run that work great. any help would be great.
Thank you.

 

12000k to 1000k would be fine. only difference is that the 10000k daylight is more white. I don't know about the white actinics.

 

Is a 420nm/12000k(UVL) considered a half actinic and half daylight?

 

UVL is just the brand. (UV Lighting). Not really half. While 10,000k is white, 20,000k is very blue. 14,000 16,000k are in between there along with 12,000k.

 

take caution my frined a kelvin change can freak out corals as they did in my wifes tank. went from 12k to 10k and everything went pastel in color and is jus now starting to come around almost 2.5 months later.
