This bulb is new, that silver shinning is normal at GIB bulbs.

When it´s a used one you can see it on the "white plastic" inside the bulb.

What I can see it´s clear white.

If needed I can make some pics for you from some 100% unused ones to compare.

Eye writing changes from brown to orange, perhaps GIB bulbs have a way of showing if used or not as well. It looks used, but could be the way the company makes the color of the glass.

Years ago the Agro bulbs started coming to me that way. A couple even had a small hole through the metal base.

I had sent some back to them as most were fine and fired like a normal looking bulb does.

Some did not however and some would burn out way to soon.

I think it is a hinky in the HPS production line, where base meets bulb.

Well it was some story like that they told to me.

They treated me very well, and once I went to the Gold bulb, I never saw it again.

 

I would assume, bulb makers, like potato chip/bread/pretzel makers, you see many different brands of bags at the end of the production lines going into the baggers, of many different brands, threaded on the baggers, to fill with your favorite potato chip.

But they are all off the same production line, and they all taste so different...

 

But I've never been in a bulb factory, so what do I know.

GIB produces there bulbs in China and Germany maybe they changed the manufacturer.

These one above are from china.

I haven't seen that on grow bulbs before, but it's the norm on amp vacuum tubes. I think it has something to do with reflecting UV back into the bulb to help heat up the element.
