Excellent Tube for FSL replacement

Review by Alex on 8/12/2019

Used this tube to replace the default Full Spectrum Laser 5th-Gen 20"x12" tube, (which is actually a 35W I think). I run this tube at just 60% of current as the old tube and it cuts much better. Slightly longer at 850mm than the default tube so had to open up the side of the housing to accommodate. Excellent packaging with soft foam and very reasonable price to Canada. Very impressed!

Great Tube for eBay 50W Laser (Shenhui SH-G350)

Review by Robert on 10/26/2018

My 50W eBay laser suddenly stopped cutting, so I ordered this tube and a few days later it was delivered to my office. Unfortunately, it turned out that my power supply was bad, not my tube, but since the tube was 3 years old I guess it was time for a replacement anyway. This tube works great and fits perfectly, I didn't even need to do any alignment and it started cutting as well as the old one right away.

Great product
