glad when I received late November 2014 but there is a month and a half a broiled I'm not worried because I have seen it lit up much more than others, but today there another who has grilled and another that has the filament that well so shaky that will soon also !! I emailed the seller to ask for the exact life of these bulbs that despite everything I find amazing !! but hey they are not given for 4 months !!
