Of the incandescent type, GE,  Sylvania and Feit are pretty comparable.  Sylvania lasted 393 days on average, but since there were only two of them it&#8217;s not statistically significant.  GE lasted 315 days on average, and Feit 360 days.  There&#8217;s probably not really enough data to distinguish between these three bulb types.<\/p>\n<p>Somewhere around 2002 I started using more and more compact flourescent bulbs.  By now I have filled most of the sockets with this type, and many of them are still working.  The flourescent bulbs that failed early show up on the graph, but shouldn&#8217;t be taken as representative of flourescent bulb life.  Some of them are still in the sockets after 3, 4 and more years.<\/p>\n<p>There&#8217;s the data; do with it what you like!<\/p>\n","protected":false},"excerpt":{"rendered":"<p>My kitchen has 7 recessed light bulbs in the ceiling.
