Hi,
I have a 5th gen machine with an original FSL 45w tube. It is around one year old (used almost every day) and is starting to show the first signs of decay.
Lightobject seems to be a popular option for tubes replacement here. (Ebay for my is more a risky alternative).

Lightoject offer a 35w tube with the measurement of the one I have (720x50mm) in the machine, common lore here is that the FSL tubes a really not 40w but 30-35 ones so it looks like a possible option:
http://www.lightobject.com/SP-35W-CO2-S ... -P208.aspx

There is other 40w tube model with the same width (50mm) but longer (850mm), it will fit on the tube holders, and the longer part could be put thought the window designed for the 90w upgrade. The tube have the same voltage/current data, but I have very little knowledge about electrics. Would it work on the 5thgen machine?

Do you have direct experience with this tubes? Have you been able to compare the light objects tubes (35 or specially 40w for a bit extra power) with the FLS ones?

Thanks!

I ordered and installed the 40w (850mm) tube a few weeks ago on the 5th gen machine and it is working perfectly.
I accomodated the extra lenght through the port intended for the 90w upgrade. The cutting is really good and stable over 3 hours or more for several days and the power is a bit higher compared to the original 45w tube from FSL (I am cutting at around +5% speed on the settings)
So I am very happy with the tube. Just lets see how long is its working life.

I highly recommend you put a metal enclosure over the end of the tube. It'll shield from RF interference, possible laser energy bouncing out that way, and potential for you coming into contact with very high voltages where your body becomes a very good conductor. It'll also eliminate any chance you drop something nearby and have it bang into the end of the tube.

Were you able to use the existing 5th Gen power supply for the 40 watt replacement tube?

The existing power supply will work with that tube just fine.

That's good to know! Thanks Thomas. My tube's still working, but sooner or later it'll need replacing.....

These are all commodity off the shelf parts. If you get a power supply for a 40-45w tube, it'll work with any manufacturer of tube. You wouldn't want to run a 90w tube on a 40w power supply though.

I've never done any work with metal. Is the metal enclosure something that I could buy or would I need to build one? Really appreciate any advice you can give.

Thanks,

Jim

Some places have the end enclosures for sale. As far as metalworking going and the possibility of making your own? It's not that hard. It's a rectangular box. You could literally just cut all the parts rectangular, then get some L channel or fold some L shaped tabs, drill and pop rivet them at the corners.
