My chinese laser machine is about 3 years old and weaker than ever.
My current tube is 800mm length and 55mm diameter.

In this link the 800mm by 55mm is rated 45W:

and in this link the 800mm by 50mm is rated 50W:

Of course china is china and I don't believe anything they declare but my question is if the size always dictates the power.
If so, I will go with the 45W to replace my current "50W" rated tube as they are the same size.

Also, was wandering, what exactly wears in a laser tube? isn't it just a piece of glass?
