So far so great

Review by Cameron on 12/17/2020

This is my first laser tube replacement and I am blown away by the difference between this and the initial cheap Chinese garbage I had initially. I'd recommend anyone getting a K40 just buy this while you're buying your machine and you'll have an excellent backup tube to use as soon as the stock one kills itself. It went in with no issues and the first thing I cut (didn't even end up needing a mirror alignment thank God) was 1/4" MDF. The first tube that came stock with my machine could handle it in 3 passes. This new tube from Light Object cut all the way through in one. Couldn't be happier with my purchase or the professional way it was safely packaged. Thanks, Light Object, you are now my go to for laser parts supply. :)

Great tube

Perfect!

Review by Kyle on 11/9/2018

Bought this to replace my tube on the K40 and it was extremely easy to install. Perfect fit and after an alignment with new SI mirrors I’m back up and running. Fast shipping and tube was packaged extremely well. Awesome product and great company.

Met my expectations

Review by Allen on 11/4/2018

I built my own BuildLog laser in 2013 and it finally died. I chose this tube as a replacement and I am glad I did. It is a quality device, actually better in person than the pictures (as of time of this review) indicate. The output head is an anodized aluminum, the water tubing is of good quality silicon (so it looks anyway) and the high voltage lead is -very- well supported and attached. I didn't care for the ground wire (too short for my application), so I discarded it but I don't count that against the tube as I was going to replace whatever came on it anyway. The glass tube was packaged quite well and I think it could easily withstand shipping issues with no issues. I purchased my other laser components here from LightObject and I will continue to do so because the support and quality of components is excellent.

Tube saved a large job

Review by Doug on 10/24/2018

The original tube just quit in the middle of a large job. Had ordered this tube to have just in case a week ago. Seems to cut much better at lower power.
