Great Tube for eBay 50W Laser (Shenhui SH-G350)
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 Tube.
I bought this to replace the "45" watt in a Full Spectrum 12x20 after 2 died in under 300 hours combined. Full Spectrum's tubes by the size are 35 watts. This tube far out-performs the Full Spectrum tube.
