The Cree A-type replacement bulbs are some of the best and lowest cost on the market.  They look like an incandescent type bulb and an industry leading 10-year warranty! 
This bulb is the daylight bulb with a color temperature of 5000K.  There is also a warm white bulb at a color temperature of 2700K that is slightly less efficient at 9.5 W.  Finally, they have a 40 W replacement at 6 W and 450 lumens at a color temperature of 2700K.  Here is a link for a comparison of all three Cree A-type replacement LED bulbs.
When the product was released it was available at Home Depot at $13.97, $1 more than the warm white variety.
