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 JK 130-watt model laser 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 32mA 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: 130W (150W peak)
  • Triggering Voltage: 30KV
  • Operating Voltage: 26KV
  • Current:    26~30mA (32mA max)
  • Length:    1700mm / 66.9 inches
  • Diameter:  80mm / 3.15  inches

    I need a replacement tube for my laser engraver/cutter and tried the JK from light object. Had it for about a month using it daily and I am very pleased .

    The Best Upgrade Ever!

    Posted by Tam on Sep 23rd 2021

    We have been battling with the GSI 80W and RECI 90W. We finally decided to pull the trigger on the 130W GSI and installed LO new power supply. It is definitely love at first sight as soon as we saw the performance output! What a beast this laser tube is! Thank you to everyone over at LO for always taking such good care of me as a customer.
