No complaints with these so far. They are bright and still working after a couple of months. If one dies particularly early I'll update the review, but I'm certain I will forget if they make it more than a year or so.They are in a recessed fixture in a bathroom that is also where the vent fan is situated, so they are in a position that is bound to be hard on bulbs. If they make it two years I'll call it a win.The light quality is good, and compared to the color temperature of the other bulbs around the house I know the temperature of they seem true to what is advertised. Can't speak to efficiency. There is just too much variance in my house to get a sense of what a couple of bulbs are doing, and the socket they are in isn't metered. If one ends up on a metered circuit I will update.
