Alright so I received the boxes of OEM bulbs and I've got to say, the bulb quality is quite different. There are only 1 and 2 SMD bulbs instead of the 3, 5, and however many found on the other versions. I was nervous that they wouldn't be nearly as bright because of this, but I found them to be just as bright or even brighter. The color is a true white versus a blue-ish white too. It really doesn't get whiter than these. I would compare them to a fluorescent bulb found in an office building.
The first pic is an example of the group buy bulbs. Second is the OEM. The third is both versions in a side by side (the best I could do!).
No more flickering too!
