Rate at 2000 hours, but experiencing more than 2000 hours so far.
The manufacturer states that the life of the laser tube is between 1200 and 2000 hours. The 2000 hours can be related to using the laser for 8 hours per day, 5 days per week, and 50 weeks per year. We have experienced that our customers do not use the laser machine this much. The actual expected use of the laser is 2 to 6 hours per day and lasts more than 2 years .. at this rate. The life of the laser tube greatly depends on what percentage of the full power that the laser tube is being used at. I try to use the laser at less than 85 percent of the rated power. The laser does not run so hot and I believe it will prolong the usability of my investment. One great thing about the Chinese laser machines is the inexpensive price for replacing the laser tube. A 40 watt laser tube can be replaced for as low as $300. Try getting a replacement laser tube for a US made laser machine and you will find a MUCH higher price.
