Title: What upgrades need to be done on the 50w version?
Post by: Network23 on July 15, 2018, 08:04:44 AM
 I pulled the trigger and ordered a 50w blue and white.  I am aware it has better parts, but was wondering what should be changed out?

I don't think anything needs to be changed out, just make sure you have a good cooling source. Use DI (or at least distilled) water in a closed system with a few drops of clear ethylene or propylene glycol (anti freeze). It will eliminate any bacterial growth.

The Chinese pumps usually don't last long, so a flow and temperature interlock switch on the coolant are very important, they will save your laser tube should something fail.

If you want the tube to last a long time, never use more than 90% power.
