TEN-HIGH 40W CO2 Laser Tube 700mm D50mm, Wires Preconnected with Coating, for Laser Cutter Laser Engraving Cutting Machine

The 40W / 700mm tube was a perfect drop-in replacement for my K40 laser cutter. The old tube had deteriorated in performance and was operating in TEM-01 mode (i.e. a split beam that diverged from the source) and could etch, but not cut through 1/8” pine in under 20 passes at 10 mm/sec. Now I have a coherent beam that focuses well and cuts all the way through the same wood in four passes at lower wattage.All seems good. Money well spent.Shipping didn’t go perfectly, but in the end it worked out.

This laser tube is a direct replacement for my Full Spectrum 5th Gen Hobby 40w laser tube that went bad. It was an easy swap out, less than a third of the price of one from Full Spectrum, and does seem more powerful than the old tube.Highly RecommendedCFH

Works fine with my manuport k40

I usually go through 2-3 tubes a year, I cut at least8 hours a day, at least 6 days a week. The last tube I got from ten high has lasted 11 months, it still works but the multiple passes is killing my production time. I’ve never had a tube that lasted this long, so I came back for another. It arrived today and to my amazement, I didn’t even have to do the regular wiring that’s required with a Full Spectrum 5th generation. It already had the wiring with the silicone and sleeves installed. I don’t know who thought of this idea but please keep it this way. I didn’t even have to open the back of my machine as I usually have to do. It took me about 10 minutes to install. I used wire nuts to secure their attached wires to my present wiring. I could kiss you, you are my hero. Thanks for such a headache free morning.

I got the tube installed pretty easily. During the process of re-aligning my mirrors, I kept getting two beams, as if I had the beam hitting the metal frame around the mirror and splitting there. Putting a small piece of card at the point where the laser leaves the tube, I verified that the lack of coherence was FROM THE TUBE! I'm returning it, and willing to try another. But dammit if it wasn't disappointing to go through the process of installing the tube just to find it had a problem. I'll update my review if the replacement works out.UPDATE: Replacement tube was great! Nice coherent beam with good cutting power! Although it was disappointing that the first one had a problem, the replacement shows there really isn't a better value for your money on these tubes!

The unit was packed well (good padding / box inside box). Wires already attached to the tube. Amazing unit & well worth the money. This "40w" unit far overpowers my original tube. I'll order from Ten-High next time (when I'm ready to move to a 60w tube.

I Ordered on April 3, 2020, Received it on April 7th 2020. It was a week or two before I could install.Worked perfectly for approximately 7 weeks. Started fading after that. Week it would only run 5 seconds and fade out. Amp meter on the machine NEVER exceeded 12-13 milliamps . VERY disapointed.I checked the day it failed and my return window had expired.For comparison purposes, I have a K40 laser with the original tube that has been running for almost 3 YEARS. I use the same power limits for it. This also shows the limited amount the laser gets used.Maybe I got a bad one? Anyway, I have a bad feeling and won't order another from this company.

I used this Laser Tube for my first replacement in my Dremel Digilab Laser. I saved $200 dollars , compared to the Dremel Laser Tube price. I had to remove the plug from my old Laser Tube and connect them to my new Laser Tube. I was concerned with the installation but it was simple. When I started my Dremel Lase it cut with no adjustments. I hope you have the same luck
