Upgrading my Chinese Shenhui G350 + Laser tube question.

[tt_bala]

Hello there guys, how are you? I have been running my chinese Shenhui G350 laser cutter for 6 years(advertised as 50 but it's really 40 as we all know).
The machine works like a charm. This machine is 500X300 (work area)

Also, the first tube started getting weak at about 3 years after I bought the machine, using it about 25 hours a week. But bad I guess, I am currently on my second tube, and my second set of mirrors + Optical lens.

I am thinking about upgrade the machine to a 700X500. I found some same grade ones made in china, with a good price, with a beam combiner(laser dot etc).

I have a few questions though before I commit.

1) Is there an alternative to chinese glass tubes? Is there something better? Anything rechargeable?
2) Does the laser last longer if you use 20% power rather than 70%?

Thank you !
