FB40/Spec35. Today's landfill find

I found these in the used bulbs at the landfill today. They are my first 40 watt u tubes. I already tested them and they both work fine. They give off a more soft white color. It is also interesting how the bulbs are stamped on opposite ends. The writing on the bulbs is identical.

I've worked in a factory.... And I can take a guess why they've been stamped in such a way.... They may have been going down a conveyor and for the sake of efficiency instead of having the "printing arm" go from one right side to the other, they decided to pair the bulbs in twos on a conveyor and have the printer move only about an inch or two every time..

That makes sense. I was guessing the same thing too. So far every bulb I have taken from the landfill works.
