I have those Cree bulbs, too. They are omnidirectional and have a very warm, slightly yellowish color like a traditional incandescent dimmed almost imperceptibly below full power. Those are my favorite for intimate lighting.
My favorite bang-for-the-buck-bulbs (also dimmable) are
THESE Feit Electric bulbs from Costco. They are cheaper in the store, $19.99 for a 3 pack, than on the website. They are 3000k, omnidirectional, and have a white, neutral hue with no blueishness.
I have tried several types from Ebay and have been disappointed by most of them.
What we need to push manufacturers to do is make reasonable output/reasonable price candelabra (E11) base bulbs. The cheapest I've seen were $10 and put out only 200 lumens or so.
Nice retrofit, where2!
