I believe the problem wasn't the bulb themselves. It was how the light grating which distributes the light was applied to the glass and how it was lined up with the tubes. You don't have the same light grating with LEDs.
Again, I respectfully request that you quit being such a sour-puss and have an open mind. You aren't contributing to this thread, just bashing every chance you get. Until you get your hands on a model, or see a review, please quit bashing. You are bashing vaporware at this point for a defect that may or may not be there, and that's just silly.
And yes, a slight rotation of a bulb can cause a sudden drop in light (causing a banding effect.) The light falloff is a function of incidence angle, IOR, and light projection angle. (The edge of a bulb doesn't appears as bright as the center.) It's non-linear, and therefor causes a sudden light shift. Thinner bulbs (from thinner sets) make this more problematic.
Sharp also noted there was a problem with how the source panel was preped. I believe this problem was solved.
