Product Description

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

This 150-watt model GSI 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 GSI 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.
