My bulb which flamed and stunk up the place, was in the upright position.
As was one of the three that I have that malfunctioned.
I believe they will hide this fact about these bulbs as long as they can, making people believe it's THEIR fault they "malfunctioned" (ie, it was "upside down" etc.).
Litigation concerning these will be hard to initiate due to the "green" money and backing involved, but once there is an actual death involving these bulbs, the trial lawyers NATIONALLY will trip over each other to get to court first.
(Ya might wanna save that bulb if ya haven't already!!)
