The Longer B1 30W laser has been a market leader for almost a year. However, Longer has now released an upgraded Longer B1 40W laser option that can power your projects with 44-48W. This promises to be a great cutting laser, but is it also an excellent engraving laser? Let's find out.

In this video, I'll review the new Longer Laser B1 40W and show how it compares to its older sibling as well as other 40W lasers. I'll show you the results of my standard test suite and then go head-to-head with the Creality Falcon 2 and xTool S1.
