Well no more assistance is needed with this for now. Thanks to everyone who helped out!
After chat last night I had some extra ideas on how to search for the bulbs I needed. By searching for "Power Compact" instead of "Compact Flourescent" I was able to locate some new possibilites.
has the 18 Watt Bulbs in 6700K and after checking with the vendor found out that they are the 9" I was looking for. They even have discounts at smaller volumes so I was able to get a price break by ordering four. Now I'll have two to put in the fixture and two spares for a year or so from now. Under $30 shipped for four!
In addition, I corresponded with a rep from ESU (manufacturer of Coralife) and they confirmed that they don't carry daylight bulbs in that size. However, he was going to forward my recommendation to start carrying them on to their product designers. Who knows, maybe they'll have them in the future.
