    Laser Tube

    Posted by Danny on Jan 5th 2022

    It's working! I replaced my 50w tube for a 90w tube. And thanks to these guys I was able pull it off. I bought this along with a new power supply. It was a bit intimidating. I emailed CS and they replied within two hours. I followed up with a phone call and talked to the same guy (Jay) that replied to my email. He already knew who I was and walked me right through it. I can't say enough about their support. It's the best!

    Good Tube

    I run 7 machines with these tubes on Light Object chillers. they run all day every day and are pretty reliable. Be sure to throttle your mA to the recommended rating and you shouldn't have any trouble.

    Tube works great

    Posted by Geno on Feb 11th 2021

    The tube came packaged VERY WELL. The wiring and water connections were included (see picture above). You have to connect the two wires to the power supply and connect the water lines to your chiller and the laser is ready to go. I run it at about 30% for cutting, and it's working great. Cuts like a charm. I would recommend the SPT tubes all day.8/10/2018
