Q: What is the best temperature to run a laser tube at?

A: The laser tube works the best at 15-20c water temp, anything above will degrade your tube. If you run at 23c your tube will not die tomorrow, but you may lower the expected life time by a couple of weeks or month. So for some its ok to run at 23c as they know they need a tube change later on.
