Alright people, I got my new Tube and everything works great.
I found out why my previous tube stopped working. (Look at images and find 1 error) 
Now my qustion to you guys is can I somehow change that mirror or will the GAS escape as soon as I pull that mirror off?
Any suggestions? 
Is that a hole in the mirror? Not certain about changing the mirror. Hopefully someone knows as it could come in handy in future.
I have a tube that has cracked glass,end mirror should be ok- where are u
@Yuusuf_Sallahuddin_Y Yes it’s a hole in the mirror! so that’s why I didn’t get the effect that I should have… there’s must have been impurities on the mirror from the start…
@Phillip_Conroy I’m located in denmark, and will definetly be happy if I could get that unused mirror of yours, but I want to see if it is possible to replace it in the first place…
Personally I don’t believe it is possible, as the photons need to hit the mirror… or else there is a glass sheet in between the mirror and to the inner gasses. but that wouldn’t be effective!
If anyone knows, please do let me know
