Most of the replacements I've looked at have listed a range for the color temperature (2500-3000K for example) with a subjective descriptor like "warm white". I recently purchased a set that was listed as "warm white" with a 3500K rating (IIRC) that was almost right. It seems to me that the difference between 2800 and 3000 would not be within most lower-cost manufacturers tolerance?
Sorry, despite all the bulbs I've tried, I still haven't found "the one". Maybe next round, I'll have better news...
