CECIndustries #6S6 130V Bulbs, 130 V, 6 W, E12 Base, S-6 Shape (Box of 10)

Bulb burned out on the particle hardness tester. Cheaper on Amazon. Works the same

I was a little concerned when I saw how these bulbs were shipped. They were all crammed together in two sheets of small plastic wrap inside a small box. Nothing was protecting them from one another on the trip. But I installed 9 of the 10 and all of them worked so I was satisfied.

These are good bulbs in the sense that I had a hard time finding any of his size and specs easily. My only criticism is that out of three packs ordered (30 bulbs), five didn't work straight out of the box. To me, this is unacceptable.
