Excellent Tube for FSL replacement
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!

Bought this to replace the factory tube that came with my "50W" Chinese blue laser. Got the tubes swapped today and the laser is cutting about 60% faster than when the factory tube was brand new. I'm very impressed. This tube is about 1" longer than the original, but I had no issues with installing it and didn't have to make any modifications.

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.10/26/2018
Light object made getting a new tube easy. So far the tube has exceeded my expectations 9/20/2018
