Our home was converted to 100% LED about 4 or so years ago. Since then, only one bulb failed and we had an outside bulb crack but it still works. Here is a short timelapse I shot of some of the bulbs going in: http://www.youtube.com/watch?v=lotVAqiDOsQ.
Light quality is amazing. Bulbs last. Reduced our energy bill by about 15% (was 100% fluorescent before the switch).
