LightObject is proudly partnered with JK Laser to be the distributor of GSI technology CO2 laser tubes in the United States. GSI tubes were highly regarded in the laser industry, offering exceptional reliability and beam diameter.

This 150-watt model tube is universal and can work with virtually any CO2 laser engraving/cutting machine, but is an ideal candidate for replacing a CO2 tube of similar power/length.

This high-output tube can handle up to 34mA at 26,000 volts. We recommend pairing this laser tube with our LightObject 1600-watt chiller to ensure ample cooling capacity.

This is an universal model and can work with almost all engraving/cutting laser units. It is a perfect replacement for the same power or length CO2 Laser tube. It is a great idea to use as an upgrade with a compatible power supply also.


  • Power: 150W (190W peak)

    150 watt tube

    Posted by David on Sep 9th 2023

    I have had four 150 watt laser tubes that have not lasted more than a year. This tube was packed very well and has a lot more power than any previous tube I have owned. I am very pleased with this tube. I did pay an additional $385 for two day shipping. The one prior to that took six weeks to get and worked for an entire week.
