If it was a gov't requirement to print the life expectancy directly on the bulb (alongside the wattage and voltage) they would all last 3,000 hours or better. And 3,000 hour bulbs would not cost 5-10x as much they would compete on price.
I remember the 2000 hr life were pretty much the "STANDARD" bulbs and then they had 3000 and 5000hr bulbs (the 5000 were basically rough service ones with out the rough service ratings.)
