Glowforge laser tubes

[mrsunnylam]

I have been doing some research for the Glowforge laser cutters. It turns out the tubes are either 40w or 45w tubes. to know the correct wattage, just measure the tube if it is

40w it should measure 850mm(33.5 inches)in length and 50mm(2 inches) in diameter,or just click the link( https://www.lightobject.com/SPT-850mm-C ... -P977.aspx).

45w should be 1000mm(39.4 inches) in length, 50mm(2 inches) in diameter. (https://www.lightobject.com/SPT-45W-CO2 ... -P751.aspx)
