A first bulb just let me go, like any lambda light bulb ... So I will avoid this model now, suddenly, I am again looking for efficient LED bulbs ... Edit: September 25, two months late, I realize that I did not provide for these new LED bulbs, 4 are now changing after two others had dropped. I preferred to change the fourth before it will turn loose because being disabled, I benefited a valid person is there to do it. That said, these bulbs are available from several vendors I think maybe I'm falling on the wrong ...
