Defective straight from the sleeve OSRAM F36T8 Daylight

Defective straight from the sleeve OSRAM F36T8 Daylight

In the workplace I also this second fixture with two tubes, and I installed in it two new German OSRAM F36T8 Daylight tubes, and one was really dim, didn't seem to warm up at all during 5 hours it was lit, also got extremely hot and it glared in these green ripples that you can see on camera - I could see those green ripples in real life too, so weird.. Maybe some of you could tell me what happened to this tube? Sadly, I don't have this tube, I threw this tube out..

It probably had an air leak, or wasn't filled properly to begin with.

I'm leaning towards to it wasn't properly filled in the factory.. sometimes these slips happen regardless of quality control

New lighting technologies is a pity fest everywhere you look. From LEDs that last only for two months, to a never-ending global starvation of t8 fluorescent tubes.
We shall reinforce ourselves with good old full mercury t12s and HIDs made to surpass one's life, and give them all the middle finger ;

Interesting. I've also had some get very hot with what is believed to be 'air' contamination or improper gas fill. Usually, mine would require much higher voltage to strike than normal ballast.

Oh yeah definitely contamination, tube was finished. Surprised it started on those ballasts which look like preheat, usually the badly contaminated ones will only work on electronic instant start ballasts with a high voltage of 600.

Probably was a tube made by Ledvance, which produces some pretty garbage products IMO. They hide behind the Sylvania name and probably also use the Osram name too
