Works Perfect

Review by Brandon Rowe on 6/10/2013

We run a Full Spectrum Laser, 40 watt and got this for the replacement tube. Fast and easy hookup. Had to adjust my mirrors and workers perfect.

K40 Replacement

Review by John on 4/20/2015

Carefully packed and delivered in perfect working order. Very steady power when the water system is working correctly: Inlet at the output mirror (-Lead) and outlet at the rear mirror (+Lead). 1.6LPH (Pump rated at 6000LPH) is enough to self purge the bubbles and gives a 1C input to output differential at 70% power = 11.5mA... Marco indicated 16mA as the maximum continuous current for this tube. I used Digikey ED1189-ND socket pins to connect the power leads: Plug onto the laser tube pins and solder to the socket solder tail. Connecting the hoses was a challenge until I made a 3/8" diameter mandrel made into a cone the same size and shape as the water inlet. Soak the hose in hot water so you can shove it 1/2 inch up the mandrel and then use freeze spray to lock it in shape. In a hurry, pull the hose off the mandrel and shove it onto the laser before it warms up at which point it shrinks onto the water inlet. VERY happy with this tube.

Works great

I purchased this to replace the stock tube that came with my K40 laser I purchased off of eBay. It shipped the same day I placed my order and was carefully packaged. It is slightly longer than the stock tube, but fits great with no modifications necessary. It works great so far and seems to have more power than my laser ever did before, even when it was new. I will definitely be back here to purchase again when I need another tube.

Tube is as described, replaced my old fading tube and this is working just like it was when the machine was new. This is for a Full Spectrum Laser 5th Generation Machine.
