Ok, since all I could get outta the fiber for glass was black with TiO2, I figured I'd try the CO2. No it's not lined up, need to make a fixture for these, and I don't know what happened around the C. Didn't notice it till I was cropping the pic.
I started with some Monport 80 watt settings I have, nothing. Then I tried Alex's settings from the LE site and converted them from 100W to 80W and got a little. In the end it was 400 mm/s @ 30%. I may try a lower % next time. I still have a few from JPP I can test with. I'll be using the ones from JDS for anything I'm gonna sell.
