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 80/90W model laser tube is universal and can work with virtually any CO2 laser engraving/cutting machine; it is an ideal candidate for replacing a CO2 tube of similar power/length(such as W2, A2s on FSL).

This high-output tube can handle up to 28mA at 22,000 volts. We recommend pairing this laser tube with our LightObject 600 chiller to ensure ample cooling capacity. Lightobject 80w laser power supply and 150w LPS are compatible with this laser tube.

    Delivers in the cutting power

    Posted by Joe on Feb 11th 2021

    Purchased this tube to replace an 80W RECI tube, most of what I was doing is cutting 1/4" MDF, and boy this tube can deliver on that. Easy to install as it comes with a screw-type connection and so far it is performing like a champ. I like the longer warranty compare to the w2, and so far I am satisfied with this tube.10/19/2020
