:O where'd you find that little gem?
Yes, the only 6" size color I'm missing is yellow. Though honestly they're more just mind blowing and cool than useful. I boggles my mind that you can get green from a tube so small. I almost didn't believe it till I saw it. I don't fired up often because I have a feeling that has a very short lifespan... At least by comparison to the other tubes. It only does something like 0.1mW, maybe 0.2 when all the planets align.
My 6" night light tube I got from Laser Sam is also .1 mw. But it was a freebie with some other stuff i got.
It runs very well and been doing so for a few years. But not continuous.
I wouldn't think the 6" would have a shorter lifespan, maybe longer. I'd be more worried with a big HeNe with bore issues and magnets, etc. But I could be wrong.
Is it green or red? Do you know the model? The smaller diameter tubes generally do have a shorter life because there is less cathode to expend. All non red hene tubes generally have a shorter life also because they are filled at a lower pressure to help with the output.
